Thanks to everyone in our community who attended the GAINS AMA yesterday with, Shiv Malik. We were excited to see that so many people attended and gladly overwhelmed by the amount of questions we got from you on Twitter and Telegram. We decided to do a little recap of the session for anyone who missed it, and to archive some points we haven’t previously discussed with our community. Happy reading and thanks to Alexandre and Henry for having us on their channel!
What is the project about in a few simple sentences?
At Streamr we are building a real-time network for tomorrow’s data economy. It’s a decentralized, peer-to-peer network which we are hoping will one day replace centralized message brokers like Amazon’s AWS services. On top of that one of the things I’m most excited about are Data Unions. With Data Unions anyone can join the data economy and start monetizing the data they already produce. Streamr’s Data Union framework provides a really easy way for devs to start building their own data unions and can also be easily integrated into any existing apps.
Okay, sounds interesting. Do you have a concrete example you could give us to make it easier to understand?
The best example of a Data Union is the first one that has been built out of our stack. It's called Swash and it's a browser plugin.
You can download it here: http://swashapp.io/
And basically it helps you monetize the data you already generate (day in day out) as you browse the web. It's the sort of data that Google already knows about you. But this way, with Swash, you can actually monetize it yourself. The more people that join the union, the more powerful it becomes and the greater the rewards are for everyone as the data product sells to potential buyers.
Very interesting. What stage is the project/product at? It's live, right?
Yes. It's live. And the Data Union framework is in public beta. The Network is on course to be fully decentralized at some point next year.
How much can a regular person browsing the Internet expect to make for example?
So that's a great question. The answer is no one quite knows yet. We do know that this sort of data (consumer insights) is worth hundreds of millions and really isn't available in high quality. So With a union of a few million people, everyone could be getting 20-50 dollars a year. But it'll take a few years at least to realise that growth. Of course Swash is just one data union amongst many possible others (which are now starting to get built out on our platform!)
With Swash, I believe they now have 3,000 members. They need to get to 50,000 before they become really viable but they are yet to do any marketing. So all that is organic growth.
I assume the data is anonymized btw?
Yes. And there in fact a few privacy protecting tools Swash supplys to its users.
How does Swash compare to Brave?
So Brave really is about consent for people's attention and getting paid for that. They don't sell your data as such.
Swash can of course be a plugin with Brave and therefore you can make passive income browsing the internet. Whilst also then consenting to advertising if you so want to earn BAT.
Of course it's Streamr that is powering Swash. And we're looking at powering other DUs - say for example mobile applications.
The holy grail might be having already existing apps and platforms out there, integrating DU tech into their apps so people can consent (or not) to having their data sold - and then getting a cut of that revenue when it does sell.
The other thing to recognise is that the big tech companies monopolise data on a vast scale - data that we of course produce for them. That is stifling innovation.
Take for example a competitor map app. To effectively compete with Google maps or Waze, they need millions of users feeding real time data into it.
Without that - it's like Google maps used to be - static and a bit useless.
Right, so how do you convince these big tech companies that are producing these big apps to integrate with Streamr? Does it mean they wouldn't be able to monetize data as well on their end if it becomes more available through an aggregation of individuals?
If a map application does manage to scale to that level then inevitably Google buys them out - that's what happened with Waze.
But if you have a data union which bundles together the raw location data of millions of people then any application builder can come along and license that data for their app. This encourages all sorts of innovation and breaks the monopoly.
We're currently having conversations with Mobile Network operators to see if they want to pilot this new approach to data monetization. And that's what even more exciting. Just be explicit with users - do you want to sell your data? Okay, if yes, then which data point do you want to sell.
Then the mobile network operator (like T-mobile for example) then organises the sale of the data of those who consent and everyone gets a cut.
Streamr - in this example provides the backend to port and bundle the data, and also the token and payment rail for the payments.
So for big companies (mobile operators in this case), it's less logistics, handing over the implementation to you, and simply taking a cut?
It's a vision that we'll be able to talk more about more concretely in a few weeks time 😁
Compared to having to make sense of that data themselves (in the past) and selling it themselves
Sort of.
We provide the backened to port the data and the template smart contracts to distribute the payments.
They get to focus on finding buyers for the data and ensuring that the data that is being collected from the app is the kind of data that is valuable and useful to the world.
(Through our sister company TX, we also help build out the applications for them and ensure a smooth integration).
The other thing to add is that the reason why this vision is working, is that the current data economy is under attack. Not just from privacy laws such as GDPR, but also from Google shutting down cookies, bidstream data being investigated by the FTC (for example) and Apple making changes to IoS14 to make third party data sharing more explicit for users.
All this means that the only real places for thousands of multinationals to buy the sort of consumer insights they need to ensure good business decisions will be owned by Google/FB etc, or from SDKs or through this method - from overt, rich, consent from the consumer in return for a cut of the earnings.
A couple of questions to get a better feel about Streamr as a whole now and where it came from. How many people are in the team? For how long have you been working on Streamr?
We are around 35 people with one office in Zug, Switzerland and another one in Helsinki. But there are team members all over the globe, we’ve people in the US, Spain, the UK, Germany, Poland, Australia and Singapore. I joined Streamr back in 2017 during the ICO craze (but not for that reason!)
And did you raise funds so far? If so, how did you handle them? Are you planning to do any future raises?
We did an ICO back in Sept/Oct 2017 in which we raised around 30 Millions CHF. The funds give us enough runway for around five/six years to finalize our roadmap. We’ve also simultaneously opened up a sister company consultancy business, TX which helps enterprise clients implementing the Streamr stack. We've got no more plans to raise more!
What is the token use case? How did you make sure it captures the value of the ecosystem you're building
The token is used for payments on the Marketplace (such as for Data Union products for example) also for the broker nodes in the Network. ( we haven't talked much about the P2P network but it's our project's secret sauce).
The broker nodes will be paid in DATAcoin for providing bandwidth. We are currently working together with Blockscience on our tokeneconomics. We’ve just started the second phase in their consultancy process and will be soon able to share more on the Streamr Network’s tokeneconoimcs.
But if you want to summate the Network in a sentence or two - imagine the Bittorrent network being run by nodes who get paid to do so. Except that instead of passing around static files, it's realtime data streams.
That of course means it's really well suited for the IoT economy.
Well, let's continue with questions from Twitter and this one comes at the perfect time. Can Streamr Network be used to transfer data from IOT devices? Is the network bandwidth sufficient? How is it possible to monetize the received data from a huge number of IOT devices? From u/ EgorCypto
Yes, IoT devices are a perfect use case for the Network. When it comes to the network’s bandwidth and speed - the Streamr team just recently did extensive research to find out how well the network scales.
The result was that it is on par with centralized solutions. We ran experiments with network sizes between 32 to 2048 nodes and in the largest network of 2048 nodes, 99% of deliveries happened within 362 ms globally.
To put these results in context, PubNub, a centralized message brokering service, promises to deliver messages within 250 ms — and that’s a centralized service! So we're super happy with those results.
Here's a link to the paper:
https://medium.com/streamrblog/streamr-network-performance-and-scalability-whitepaper-adb461edd002
While we're on the technical side, second question from Twitter: Can you be sure that valuable data is safe and not shared with service providers? Are you using any encryption methods? From u/ CryptoMatvey
Yes, the messages in the Network are encrypted. Currently all nodes are still run by the Streamr team. This will change in the Brubeck release - our last milestone on the roadmap - when end-to-end encryption is added. This release adds end-to-end encryption and automatic key exchange mechanisms, ensuring that node operators can not access any confidential data.
If BTW - you want to get very technical the encryption algorithms we are using are: AES (AES-256-CTR) for encryption of data payloads, RSA (PKCS #1) for securely exchanging the AES keys and ECDSA (secp256k1) for data signing (same as Bitcoin and Ethereum).
Last question from Twitter, less technical now :) In their AMA ad, they say that Streamr has three unions, Swash, Tracey and MyDiem. Why does Tracey help fisherfolk in the Philippines monetize their catch data? Do they only work with this country or do they plan to expand? From u/ alej_pacedo
So yes, Tracey is one of the first Data Unions on top of the Streamr stack. Currently we are working together with the WWF-Philippines and the UnionBank of the Philippines on doing a first pilot with local fishing communities in the Philippines.
WWF is interested in the catch data to protect wildlife and make sure that no overfishing happens. And at the same time the fisherfolk are incentivized to record their catch data by being able to access micro loans from banks, which in turn helps them make their business more profitable.
So far, we have lots of interest from other places in South East Asia which would like to use Tracey, too. In fact TX have already had explicit interest in building out the use cases in other countries and not just for sea-food tracking, but also for many other agricultural products.
(I think they had a call this week about a use case involving cows 😂)
I recall late last year, that the Streamr Data Union framework was launched into private beta, now public beta was recently released. What are the differences? Any added new features? By u/ Idee02
The main difference will be that the DU 2.0 release will be more reliable and also more transparent since the sidechain we are using for micropayments is also now based on blockchain consensus (PoA).
Are there plans in the pipeline for Streamr to focus on the consumer-facing products themselves or will the emphasis be on the further development of the underlying engine?by u/ Andromedamin
We're all about what's under the hood. We want third party devs to take on the challenge of building the consumer facing apps. We know it would be foolish to try and do it all!
As a project how do you consider the progress of the project to fully developed (in % of progress plz) by u/ Hash2T
We're about 60% through I reckon!
What tools does Streamr offer developers so that they can create their own DApps and monetize data?What is Streamr Architecture? How do the Ethereum blockchain and the Streamr network and Streamr Core applications interact? By u/ CryptoDurden
We'll be releasing the Data UNion framework in a few weeks from now and I think DApp builders will be impressed with what they find.
We all know that Blockchain has many disadvantages as well,
So why did Streamr choose blockchain as a combination for its technology?
What's your plan to merge Blockchain with your technologies to make it safer and more convenient for your users? By u/ noonecanstopme
So we're not a blockchain ourselves - that's important to note. The P2P network only uses BC tech for the payments. Why on earth for example would you want to store every single piece of info on a blockchain. You should only store what you want to store. And that should probably happen off chain.
So we think we got the mix right there.
What were the requirements needed for node setup ? by u/ John097
Good q - we're still working on that but those specs will be out in the next release.
How does the STREAMR team ensure good data is entered into the blockchain by participants? By u/ kartika84
Another great Q there! From the product buying end, this will be done by reputation. But ensuring the quality of the data as it passes through the network - if that is what you also mean - is all about getting the architecture right. In a decentralised network, that's not easy as data points in streams have to arrive in the right order. It's one of the biggest challenges but we think we're solving it in a really decentralised way.
What are the requirements for integrating applications with Data Union? What role does the DATA token play in this case? By u/ JP_Morgan_Chase
There are no specific requirements as such, just that your application needs to generate some kind of real-time data. Data Union members and administrators are both paid in DATA by data buyers coming from the Streamr marketplace.
Regarding security and legality, how does STREAMR guarantee that the data uploaded by a given user belongs to him and he can monetize and capitalize on it? By u/ kherrera22
So that's a sort of million dollar question for anyone involved in a digital industry. Within our system there are ways of ensuring that but in the end the negotiation of data licensing will still, in many ways be done human to human and via legal licenses rather than smart contracts. at least when it comes to sizeable data products. There are more answers to this but it's a long one!
Okay thank you all for all of those!

IBM Will Unleash Commercial "Universal" Quantum Computers This Year

CryptoTools.net - A simple client-side cryptographic tool suite

Hey everyone! My apologies in advance from the plug, but I just wanted to show off my project, CryptoTools.net. It has no ads, no trackers, and does not ask for money.

Backstory

I got sick of bouncing around from site to sketchy site while trying to perform the simplest of cryptographic operations: things like hashing a string, converting base64, or encrypting a string. Each site had their own way of doing things as well, with a large portion of them POSTing all of the data to the server for it to do the calculations (a major no-no for those unfamiliar). Even some of the good sites were single-purpose with clunky UIs and forgettable URLs. I have yet to meet anyone who has memorized every OpenSSL command, myself included.
There's no shortage of crypto implementations in Javascript, but they're usually implemented in the background of a larger application, not presented in plain form for users to take advantage of as they please.
For these reasons, I decided to make my own collection of tools. All client side, easy to use, mobile friendly, and compatible with OpenSSL! Most tools also include DIY instructions for self-serve. All source code is on GitHub and all libraries are attributed to their authors. Rule #1 of crypto is to never roll your own crypto, so only outside libraries were used for that.

Tools

I hope at least some of you find these tools as useful as I do! I'm always open to suggestions for improvement. Thanks for reading!

Evidence Points to Bitcoin being an NSA-engineered Psyop to roll out One-World Digital Currency

Eye
I'm going to assume the readers who make it to this article are well informed enough that I don't have to go into the history of the global money changers and their desire for a one world currency.
(If you don't yet understand the goal of the globalist banking empire and the coming engineered collapse of the fiat currency system, you're already about 5,000 posts behind the curve.)
With that as a starting point, it's now becoming increasingly evident that Bitcoin may be a creation of the NSA and was rolled out as a "normalization" experiment to get the public familiar with digital currency.
Once this is established, the world's fiat currencies will be obliterated in an engineered debt collapse (see below for the sequence of events), then replaced with a government approved cryptocurrency with tracking of all transactions and digital wallets by the world's western governments.
NSA mathematicians detailed "digital cash" two decades ago
What evidence supports this notion?
First, take a look at this document entitled, "How to Make a Mint - The Cryptography of Anonymous Electronic Cash." This document, released in 1997 - yes, twenty years ago - detailed the overall structure and function of Bitcoin cryptocurrency.
Who authored the document?
Try not to be shocked when you learn it was authored by,
"mathematical cryptographers at the National Security Agency's Office of Information Security Research and Technology." 
The NSA, in other words, detailed key elements of Bitcoin long before Bitcoin ever came into existence.
Much of the Bitcoin protocol is detailed in this document, including signature authentication techniques, eliminating cryptocoin counterfeits through transaction authentication and several features that support anonymity and untraceability of transactions.
The document even outlines the heightened risk of money laundering that's easily accomplished with cryptocurrencies. It also describes "secure hashing" to be "both one-way and collision-free."
Although Bitcoin adds mining and a shared, peer-to-peer blockchain transaction authentication system to this structure, it's clear that the NSA was researching cryptocurrencies long before everyday users had ever heard of the term.
Note, too, that the name of the person credited with founding Bitcoin is Satoshi Nakamoto, who is reputed to have reserved one million Bitcoins for himself.
Millions of posts and online threads discuss the possible identity of Satishi Nakamoto, and some posts even claim the NSA has identified Satoshi.
However, another likely explanation is that Satoshi Nakamoto is the NSA, which means he is either working for the NSA or is a sock puppet character created by the NSA for the purpose of this whole grand experiment.
The NSA also wrote the crypto hash used by Bitcoin to secure all transactions
On top of the fact that the NSA authored a technical paper on cryptocurrency long before the arrival of Bitcoin, the agency is also the creator of the SHA-256 hash upon which every Bitcoin transaction in the world depends.
As The Hacker News (THN) explains.
"The integrity of Bitcoin depends on a hash function called **SHA-256**, which was designed by the NSA and published by the *National Institute for Standards and Technology* ([NIST](https://en.wikipedia.org/wiki/National_Institute_of_Standards_and_Technology))." 
THN also adds:
"If you assume that the NSA did something to SHA-256, which no outside researcher has detected, what you get is the ability, with credible and detectable action, they would be able to forge transactions. The really scary thing is somebody finds a way to find collisions in SHA-256 really fast without brute-forcing it or using lots of hardware and then they take control of the network." 
Cryptography researcher Matthew D. Green of Johns Hopkins University said.
In other words, if the SHA-256 hash, which was created by the NSA, actually has a backdoor method for cracking the encryption, it would mean the NSA could steal everybody's Bitcoins whenever it wants (call it "Zero Day.")
That same article, written by Mohit Kumar, mysteriously concludes,
"Even today it's too early to come to conclusions about Bitcoin. Possibly it was designed from day one as a tool to help maintain control of the money supplies of the world." 
And with that statement, Kumar has indeed stumbled upon the bigger goal in all this:
To seize control over the world money supply as the fiat currency system crumbles and is replaced with a one-world *digital currency controlled by globalists*. 
Think cryptography is bulletproof? Think again…
Lest you think that the cryptography of cryptocurrency is secure and bulletproof, consider this article from The Hacker News, 'Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto Library,' which states,
"The attack allows an attacker to extract the secret crypto key from a system by analyzing the pattern of memory utilization or the electromagnetic outputs of the device that are emitted during the decryption process." 
Note, importantly, that this is a 1024-bit encryption system.
The same technique is also said to be able to crack 2048-bit encryption. In fact, encryption layers are cracked on a daily basis by clever hackers.
Some of those encryption layers are powering various cryptocurrencies right now. Unless you are an extremely high-level mathematician, there's no way you can know for sure whether any crypto currency is truly non-hackable.
In fact, every cryptocurrency becomes obsolete with the invention of large-scale quantum computing.
Once China manages to build a working 256-bit quantum computer, it can effectively steal all the Bitcoins in the world (plus steal most national secrets and commit other global mayhem at will).

Ten steps to crypto-tyranny - The "big plan" by the globalists (and how it involves Bitcoin)
In summary, here's one possible plan by the globalists to seize total control over the world's money supply, savings, taxation and financial transactions while enslaving humanity.
And it all starts with Bitcoin...
  1.  Roll out the NSA-created Bitcoin to get the public excited about a digital currency. 
  2.  Quietly prepare a globalist-controlled cryptocurrency to take its place. (JP Morgan, anyone...?) 
  3.  Initiate a massive, global-scale [false flag operation](http://www.bibliotecapleyades.net/sociopolitica/sociopol_falseflag.htm) that crashes the global debt markets and sends fiat currencies down in flames (hoax alien invasion, hoax North Korean EMP attack, mass distributed power grid terrorism network, etc.) 
  4.  Blame whatever convenient enemy is politically acceptable (North Korea, "the Russians," Little Green Men or whatever it takes…) 
  5.  Allow the fiat currency debt pyramid to collapse and smolder until the sheeple get desperate. 
  6.  With great fanfare, announce a government-backed cryptocurrency replacement for all fiat currencies, and position world governments as the SAVIOR of humanity. Allow the desperate public to trade in their fiat currencies for official crypto currencies. 
  7.  [Outlaw cash](http://www.bibliotecapleyades.net/sociopolitica/sociopol_globalbanking.htm#Cashless_Society) and *criminalize gold and silver ownership by private citizens*. All in the name of "security," of course. 
  8.  Criminalize all non-official cryptocurrencies such as Bitcoin, crashing their value virtually overnight and funneling everyone into the one world government crypto, where the NSA controls the blockchain. This can easily be achieved by blaming the false flag event (see above) on some nation or group that is said to have been "funded by Bitcoin, the cryptocurrency used by terrorists." 
  9.  Require [embedded RFID](http://www.bibliotecapleyades.net/ciencia/secret_projects/implants.htm#RFID) or biometric identifiers for all transactions in order to "authenticate" the one-world digital crypto currency activities. *Mark of the Beast* becomes reality. No one is allowed to eat, travel or earn a wage without being marked. 
  10.  Once absolute control over the new one-world digital currency is achieved, weaponize the government-tracked blockchain to track all transactions, investments and commercial activities. Confiscate a portion of all crypto under the guise of "automated taxation." In an emergency, the government can even announce *negative interest rates* where your holdings automatically decrease each day. 
With all this accomplished, globalists can now roll out absolute totalitarian control over every aspect of private lives by enforcing financial "blackouts" for those individuals who criticize the government.
They can put in place automatic deductions for traffic violations, vehicle license plate taxes, internet taxes and a thousand other oppressive taxes invented by the bureaucracy.
With automatic deductions run by the government, citizens have no means to halt the endless confiscation of their "money" by totalitarian bureaucrats and their deep state lackeys.
How do you feel about your Bitcoin now...?

Cutting to the chase or how to properly evaluate privacy coins!

EDIT Be aware, the moderators of cryptocurrency have SHADOW DELETED without cause the original thread. This is most likely at the request of the XMR community. Also, the Monero community continues to Vote-Brigade this thread. Originally 11-14 upvotes, and even today 5 upvotes, they make sure it stays around 1. This is manipulation.
https://np.reddit.com/CryptoCurrency/comments/9gl5xp/cutting_to_the_chase_or_how_to_properly_evaluate/
This causes the post to appear to me, but to everyone else its been deleted. Now, why would they undertake such an underhanded tactic?
End EDIT
There's a lot of talk about anonymity and privacy as it relates to blockchains. Recently a report surfaced mentioning that cryptos are basically bad news for criminals: https://dailyhodl.com/2018/09/16/bitcoin-is-actually-a-money-laundering-tracking-device-that-catches-criminals-report/
TL;DR is at the bottom
Why? Because they're easy to track. Once they've got a single piece of identifying info that's linked to an address (say that coinbase transfer to an exchange) then all transactions are linkable to that id. But, privacy coins are different because they obscure this history (or in some cases 'delete' it all together). However, it can be a little difficult to decide which privacy coin offers the best privacy, along with the best combination of fees, security and usability.
So with no further ado, here is your simple guide to evaluating privacy coins! Like daily tx throughput is a key metric of btc/blockchain adoption and usage, privacy coins have their own 'key metric' to determine their ability to hide your tx history: the size of their anonymity set. This is basically the number of other people with which your transaction is plausibly 'mixed' so at to sever the link between your address and that coin. The greater this number is, the more difficult it is to associate a coin with your address, thus making it more private.
To make this easier to understand, it helps to know the following: All privacy coins do the same thing, just in vastly different ways. What is that thing? Obscuring/removing your linkage to a coin by mixing it with a similar coin denomination from another wallet. Monero is a slight exception to this, since transaction amounts are hidden in the blockchain as well, so there's no need for denominations. Also, your coin is mixed with fake coins that aren't real, instead of coins from other wallets, but no one can tell that from the blockchain so it works.

Dash

It should be noted that in Dash, the anonymity set is the total set of each denomination. So if you send a .1 Dash privateSend transaction, the anonymity set is the set of all .1 Dash. The following only applies if you've bought up more than 70% of the masternodes, and only to transactions that are currently being mixed. Previously mixed transactions cannot be deanoned.
In Dash, it depends on how many rounds you mix. Each coin is once again broken down into standard denominations like 10, 1, .1 .01 and most recently, .001 Dash. Each round involves a minimum of three different wallets. So take the number of participants and raise it to the rounds you mix-th power, and that is your minimum anonymity set.
So mixing four rounds gives you a minimum anonymity set of (3 participants)4 rounds = 81. Eight rounds gives you a min set of 38 = 6,561. 16 rounds give you a min set of 316 = 43,046,721 which is currently the second largest anonymity set of all the privacy coins.
Could be more if more than three wallets were involved in any single mix, which is possible. However, it could be less if the same participants are used per round, which is unlikely. This is still a HUGE anonymity set; however, its probably at least an order of magnitude less than PIVX and ZCoin unless you were to get 4-5 wallets mixing per round. Dash's anon-set is the second largest in the private coin space and is around 3x larger than PIVX's.
Still, even 81 could be rightly considered overkill, especially since Considering the nature of privateSend and the random separation between 'minting' and spending, Dash is immune to timing analysis attacks. The determination of which coin to use will come down to your anonymity needs. How private do you need to be?

PIVX

In PIVX, for example, ~10-20% of all pivx held in wallets is 'gathered' by the accumulator (note it never leaves your control) in a central pool of zpiv using standard denominations like 10 zpiv, 1zpiv, .1zpiv etc. This is a configurable setting in the wallet so some may wish to turn it on/off at their discretion, but recent research has shown that 24% of all PIVX held in wallets is private/zpiv, see u/turtleflax's comment below.
After all of that, by using a zero-knowledge proof which cryptographically proves you owned whatever zpiv was minted from your wallet without any linking information to you, zpiv is 'sent' to your wallet and shows up with no transaction history. So the anonymity set is 10%, 24% nowadays, of all PIVX held in wallets, which is obviously huge. In Apr 2019 a vulnerability was discovered in the ZeroCoin protocol that PIVX and ZCoin both share.
Now that the issue has been confirmed, we will no longer wait for the soft-fork to complete and will release a new wallet that will allow conversion of all zPIV held in the wallet to PIV. This will mean that all users will be able to fully access their funds immediately once released. This new release will be mandatory, and the zPIV spends will no longer be private in light of this new vulnerability.
Which means that for now, PIVX's privacy has been shut off and zpiv spends are no longer private, putting PIVX at 0 currently.

ZCoin

In Apr 2019 a cryptographic vulnerability was discovered with the ZeroCoin protocol. This was not a coding error but a flaw in the mathematical proof that ZeroCoin's design was based on. This has lead to ZCoin disabling their privacy feature.
>We found the root cause of the irregular Zerocoin spends on the 19 April 2019. An emergency update 13.7.9 is now available to disable Zerocoin completely while we move to our Sigma implementation. We are in touch with a number of other Zerocoin projects and are working together to secure it.
>We recommend any projects utilizing Zerocoin (regardless of which implementation you are using) to disable Zerocoin on sporks or at a consensus layer.
ZCoin has recently on July 23 2019 released their newly updated Sigma privacy protocol which replaces the ZeroCoin protocol. Zerocoin had an issue before that caused them to shut it down, and now they have released the Sigma protocol.
It is another encryption based scheme, but this time without the trusted setup and relying on well-known cryptographic primitives, i.e. the algorithms they use to build the encryption are well-known and time-tested. They've been investigated for bugs and are all deployed actively in other systems, thus, a similiar bug becomes less likely. ZeroCoin was groundbreaking, but also very experimental.
With this, the Anonymity set size of ZCoin becomes 214 = 16,384.
Here is how they describe its functioning:
Sigma is based on the academic paper One-Out-Of-Many-Proofs: Or How to Leak a Secret and Spend a Coin (Jens Groth and Markulf Kohlweiss) which replaces RSA accumulators by utilizing Pedersen commitments and other techniques which cryptographic construction does not require trusted setup.
The only system parameters required in the Sigma setup are ECC group specifications and the group generators. This construction was further optimized in the paper Short Accountable Ring Signatures based on DDH (Jonathan Bootle, Andrew Cerulli, Pyrros Chaidos, Essam Ghadafi, Jens Groth and Christophe Petit).
Proof sizes are significantly reduced from 25 kB in Zerocoin to 1.5 kB in Sigma which is almost a 17x reduction making it a lot cheaper to store on the blockchain and making it possible to fit much more private send transactions in a block. We also utilize the improved Sigma techniques in the paper Short Accountable Ring Signatures Based on DDH to reduce proof sizes further. This solves one of the biggest problems of Zerocoin without reducing its security.
Security via the usage of 256 bit ECC curves in Sigma is improved compared to 2048 bit RSA used in Zerocoin and is estimated to be equivalent to 3072 bit RSA.
Our implementation also uses Pippenger and Straus’ multi exponentiation algorithms for further verification efficiency.
There's a lot of tech speak in there. Suffice it to say that Sigma utilizes well-known cryptographic algorithms without a trusted setup to provide a pretty strong privacy offering, with a anonymity set size more than 10,000.

ZCash

ZCash is an implementation of the ZeroCash protocol which is an improvement on the ZeroCoin protocol. The cool thing about ZCash is that it also hides the amount of the transaction. ZCash's privacy is optional and the blockchain is split between t-addresses and z-addresses. t-addrs are transparent and contain visible balances just like Bitcoin, which ZCash is a software fork of. z-addrs are shielded. ZCash appears to have two kinds of shielded transactions (shielded and fully shielded).
I'm not sure of the difference between them, but according to this handy block explorer: https://explorer.zcha.in/statistics/usage, shielded txs are far more prevalent than fully shielded ones. The difference between them may be that fully shielded txs are transactions between two z-addrs while a tx that is 'just shielded' may be one between a z-addr and a t-addr and possibly a t-addr and a z-addr, but again, I'm not sure.
The developers claim that the anonymity set is very large in comparison to coins like Dash, and since it is based on the ZeroCash, it is reasonable to assume its anon set is similarly large and based on a proportion of the supply, though where among the three it stands is of course up for debate/verification. However, with Dash's recent protocol update to v0.13, privateSend now has the second largest possible anonymity set among the privacy coins. At 43 million, it is less than ZEC's (4.3 Billion) but greater than ZCoin's (~16,000) and PIVX's (currently 0), Monero's (only 11) and Bitcoin Cash's (5).
Zec's anon-set is perhaps as large as the shielded value colume for any time period, also note that is a lower bound, so for the past month: 394989 ZEC would be the total shielded ZEC, so this seems a reasonable lower-bound on the Anon-set. Its hard to Tell between this and PIVX which is larger.
According to this page the anonymity set size for ZEC is 232 = 4,294,967,296 granting it the largest anonymity set size in the space, several orders of magnitude larger than runner-up Dash at ~43,000,000 @ 16 rounds of mixing.

Monero

In Monero, the anonymity set is the number of mixins used at the time of your transaction. Which is currently 11 with the most recent update to bulletproofs. Monero originally had optional privacy where the min mixin was 0 and those transactions were transparent like btc's.
However, having these 0 mixin transactions together with the higher mixin transactions allowed for higher ones to be deanoned, that and 3 forms of timing analysis attacks forced the min mixin to be raised to 3, then 5 then 7 and finally its current static value. With the latest update the ring size, previously a wallet-configurable parameter, is now fixed at 11 for everyone.

Bitcoin Cash

With Bitcoin cash adding its CashShuffle protocol, they too join the ranks of the privacy coins. Each mixing is done with 4 other participants giving an anonymity set of 5.

TL;DR

So in short, if you want to rank privacy coins by their anon-set size (which is the only thing that matters) the list is as follows:

1. ZCash 4,294,967,296

2. Dash 43,046,721

3. ZCoin 16,384

4. Monero 11

5. Bitcoin Cash 5

Note: Each tier except the last generally represents a range of at least >1 order of magnitude greater anonymity set. So ZCash is two orders of magnitude greater than Dash, which is 3 orders of magnitude greater than ZCoin which is 3 orders of magnitude greater than Monero which is in the same order of magnitude as BCH. Monero's default min mixin is 7 and the max definable in the gui wallet IIRC is 26 ring size is fixed at 11 for everyone. It is no longer possible to select your own ring size per tx.
Due to the optional nature of how many rounds a user can select in Dash (default 4-16), there is a wide range of possible anon set sizes for Dash, most other coins have a predetermined anon set like Monero which is fixed at 11 currently, and Bitcoin Cash which uses a single round of mixing with 5 total participants.
But for Dash, which may on occasion cross into fall into the grey zone between numbers 4 and 2 due to uncertainty around the number of wallets participating, and the fact that an attacker will never know how many rounds a tx is going through, as well as the users ability to choose different rounds. The more rounds selected the higher the anonymity set.
Also, because Dash doesn't rely on encryption for its privacy, if you don't catch/trace the transaction when its happening, i.e. by buying up 70% or more of the masternodes in order to attempt to link outputs between participants, you can never deanon it. If you use encryption, especially for the entire blockchain, you paint a large target on your blockchain. If your encryption is ever broken, then all past transactions will be deanoned at once, so not good. This is a benefit of steganography over some encryption based privacy schemes. Edit:
Don't worry, my comments and posts are always heavily downvoted, that's how you know they're good stuff!

CryptoLocker Recap: A new guide to the bleepingest virus of 2013.

As the previous post, "Proper Care & Feeding of your CryptoLocker Infection: A rundown on what we know," has hit the 500 comment mark and the 15,000 character limit on self-posts, I'm going to break down the collected information into individual comments so I have a potential 10000 characters for each topic. There is a cleaner FAQ-style article about CryptoLocker on BleepingComputer.
Special thanks to the following users who contributed to this post:
I will be keeping a tl;dr recap of what we know in this post, updating it as new developments arise.
tl;dr: CryptoLocker encrypts a set of file masks on a local PC and any mapped network drives with 2048-bit RSA encryption, which is uncrackable for quite a while yet. WinXP through Win8 are vulnerable, and infection isn't dependent on being a local admin or having UAC on or off. MalwareBytes Pro and Avast stop the virus from running. Sysadmins in a domain should create this Software Restriction Policy which has very little downside (you need both rules). The timer it presents is real and you cannot pay them once it expires. You can pay them with a GreenDot MoneyPak or 2 Bitcoins, attempt to restore a previous version using ShadowExplorer, go to a backup (including versioning-based cloud backups), or be SOL.
EDIT: I will be updating individual comments through the evening to flesh out areas I had to leave bare due to character limitations or lack of info when they were originally written.
EDIT 2: There are reports and screenshots regarding a variant that sits in AppData/Local instead of Roaming. This is a huge development and I would really appreciate a message with a link to a sample of this variant if it does indeed exist. A current link to the known variant that sits in Roaming would also be appreciated.
10/24/13 EDIT: Please upvote How You Can Help for visibility. If you can contribute in any of those fashions it will help all of us a lot.
11/11/13 EDIT: Thanks to everyone that submitted samples. The latest '0388' variant can be found at http://bluesoul.me/files/0388.zip which is password protected, password is "infected". Please see Prevention for updated SRPs.

Proper Care & Feeding of your CryptoLocker Infection: A rundown on what we know.

This article is no longer being maintained, please see the new version here. Thanks.
tl;dr: I hope you have backups. It's legit, it really encrypts. It can jump across mapped network drives and encrypt anything with write access, and infection isn't dependent on being a local admin or UAC state. Most antiviruses do not catch it until the damage is done. The timer is real and your opportunity to pay them goes away when it lapses. You can pay them with a GreenDot MoneyPak or 2 Bitcoins, attempt to restore a previous version using ShadowExplorer, go to a backup, or be SOL.
Vectors: In order of likelihood, the vectors of infection have been:
  • Email attachments: A commonly reported subject is Payroll Report. The attachment, most of the time, is a zip with a PDF inside, which is actually an executable.
  • PCs that are unwitting members of the Zeus botnet have had the virus pushed to them directly.
  • There is currently one report of an infection through Java, using the .jnlp file as a dropper to load the executable.
Variants: The current variant demands $300 via GreenDot MoneyPak or 2 BTC. I will not attempt to thoroughly monitor the price of bitcoins for this thread, use Mt. Gox for the current exchange rate. Currently the MoneyPak is the cheaper option, but last week Bitcoins were. Two variants, including a $100 variant and a $300 that did not offer Bitcoin, are defunct.
Payload: The virus stores a public RSA 2048-bit key in the local registry, and goes to a C&C server for a private key which is never stored. The technical nuts and bolts have been covered by Fabian from Emsisoft here. It will use a mix of RSA 2048-bit and AES 256-bit encryption on files matching these masks:
*.odt, *.ods, *.odp, *.odm, *.odc, *.odb, *.doc, *.docx, *.docm, *.wps, *.xls, *.xlsx, *.xlsm, *.xlsb, *.xlk, *.ppt, *.pptx, *.pptm, *.mdb, *.accdb, *.pst, *.dwg, *.dxf, *.dxg, *.wpd, *.rtf, *.wb2, *.mdf, *.dbf, *.psd, *.pdd, *.eps, *.ai, *.indd, *.cdr, ????????.jpg, ????????.jpe, img_*.jpg, *.dng, *.3fr, *.arw, *.srf, *.sr2, *.bay, *.crw, *.cr2, *.dcr, *.kdc, *.erf, *.mef, *.mrw, *.nef, *.nrw, *.orf, *.raf, *.raw, *.rwl, *.rw2, *.r3d, *.ptx, *.pef, *.srw, *.x3f, *.der, *.cer, *.crt, *.pem, *.pfx, *.p12, *.p7b, *.p7c, *.pdf, *.tif
This list of file masks may be incomplete. Trust this list at your peril. When in doubt, CryptoLocker will show you what files it has encrypted by clicking the relevant link in the virus's message.
It will access mapped network drives that the current user has write access to and encrypt those. It will not attack server shares, only mapped drives. Current reports are unclear as to how much permission is needed for the virus to encrypt a mapped drive, and if you have clarification or can test in a VM please notify me via message.
By the time the notification pops up, it's already encrypted everything. It's silent until the job is done.
Many antiviruses have been reported as not catching the virus until it's too late, including MSE, Trend Micro WFBS, Eset, GFI Vipre, and Kaspersky. They can further complicate matters by reverting registry changes and removing the executables, leaving the files behind without a public or private key. Releasing the files from quarantine does work, as does releasing the registry keys added and downloading another sample of the virus.
Windows XP through 8 have all reported infections.
What's notable about this virus, and this is going to lead to a lot of tough decisions, is that paying them to decrypt the files actually does work, so long as their C&C server is up. They verify the money transfer manually and then push a notification for the infected machine to call home for the private key again, which it uses to decrypt. It takes a long time to decrypt, at the rate of roughly 5GB/hr based on forum reports. The virus uses the registry to maintain a list of files and paths, so not moving the files around is vital to decryption if you are paying them.
Also notable is that the timer it gives you to pay them does appear to be legitimate, as multiple users have reported that once the timer ran out, the program uninstalled itself. Reinfecting the machine does not bring a new timer. I was not able to verify the uninstallation of the program after the timer ran out, it appears to be dependent on internet access.
Due to the nature of the encryption, brute-forcing a decrypt is essentially impossible for now.
Removal: Removing the virus itself is trivial, but no antivirus product (or any product, for that matter), will be able to decrypt the files until the private key is found.
File Recovery: There are only a handful of options for recovering encrypted files, and they all rely on either having System Restore/VSS turned on or having a backup disconnected from the infected machine. Cloud backup solutions without versioning are no good against this as they will commit the encrypted files to the cloud.
I had a Carbonite employee message me regarding my earlier statement that Carbonite is no good against this virus. It turns out that versioning is included in all Carbonite plans and support all agent OSes except Mac OS X which is outside the scope of this thread anyway. They have the ability to do a mass reversion of files, but you must call tech support and upon mentioning CryptoLocker you will be escalated to a tier 3 tech. They do not mention this ability on the site due to the potential for damage a mass reversion could do if done inadvertently. These are my own findings, independent of what the employee told me. Crashplan and other versioning-based backup solutions such as SonicWALL CDP should also work fine provided the backups are running normally.
Using the "Previous Versions" tab of the file properties is a cheap test, and has had mixed results. Using ShadowExplorer on Vista-8 will give you a much easier graphical frontend for restoring large amounts of files at once (though this will not help with mapped drives, you'd need to run it on the server in that case). Undelete software doesn't work as it encrypts the files in place on the hard drive, there is no copying going on. The big takeaway is that cold-storage backups are good, and they will make this whole process laughably easy to resolve.
Prevention: As this post has attracted many home users, I'll put at the top that MalwareBytes Pro, Avast! Free and Avast! Pro (defs 131016-0 16.10.2013 or later) will prevent the virus from running.
For sysadmins in a domain environment, one way to prevent this and many other viruses is to set up software restriction policies (SRPs) to disallow the executing of .exe files from AppData/Roaming. Grinler explains how to set up the policy here.
Visual example. The rule covering %AppData%\*\*.exe is necessary for the current variant. The SRP will apply to domain admins after either the GP timer hits or a reboot, gpupdate /force does not enforce it immediately. There is almost no collateral damage to the SRP. Dropbox and Chrome are not effected. Spotify may be affected, not sure. I don't use it.
Making shares read-only will mitigate the risk of having sensitive data on the server encrypted.
Forecast: The reports of infections have risen from ~1,300 google results for cryptolocker to over 150,000 in a month. This virus is really ugly, really efficient, and really hard to stop until it's too late. It's also very successful in getting people to pay, which funds the creation of a new variant that plugs what few holes have been found. I don't like where this is headed.
Some edits below are now redundant, but many contain useful information.
9/17 EDIT: All 9/17 edits are now covered under Prevention.
10/10 EDIT: Google matches for CryptoLocker are up 40% in the last week, and I'm getting 5-10 new posts a day on this thread, so I thought I'd update it with some interesting finds from fellow Redditors.
  • soulscore reports that setting the BIOS clock back in time added time to his cryptolocker ransom. Confirmed that the timer extends with the machine offline, but that may be cosmetic and I don't like your chances of this actually helping if your timer runs out on the server side.
  • Spinal33 reports that AV companies are catching up with CryptoLocker and are blocking websites that are spawned in the virus's domain generation algorithm. This effectively means that some people are locked out of the ability to even pay the ransom. (Technically they could, but the virus couldn't call home.)
  • Malwarebytes is claiming that MBAM Pro will catch CryptoLocker. If someone wants to test them on it, be my guest. Confirmed
  • CANT_ARGUE_DAT_LOGIC gave some insight on the method the virus uses when choosing what to infect. It simply goes through folders alphabetically and encrypts all files that match the filemasks towards the top of this post. If you are lucky enough to catch it in the act of encrypting and pull the network connection, the CryptoLocker message will pop up immediately and the countdown will begin. Helpful in determining what will need to be taken into account for decryption.
EDIT 2: We had a customer that ignored our warning email get infected so I will have my hands on an infected PC today, hope to have some useful info to bring back.
10/10 MEGA EDIT: I now have an active CryptoLocker specimen on my bench. I want to run down some things I've found:
  • On WinXP at least, the nested SRP rule is necessary to prevent infection. The path rule needs to be %AppData%\*\*.exe
  • An alternate link to the virus sample is http://gktibioivpqbot.net/1002.exe
  • Once the program runs it spawns two more executables with random names in %userprofile%. Adding a SRP to cover %userprofile%\*.exe may be desired, though this will prevent GoToMyPC from running at a bare minimum.
  • This user was a local administrator, and CryptoLocker was able to encrypt files in other user's directories, though it did not spawn the executables anywhere but the user that triggered the infection. When logged in under a different account there is no indication that a timer is running.
  • The environment has server shares but no mapped drives and the shared data was not touched, even though a desktop shortcut would've taken the virus to a share. I suspect that will be covered in the next iteration.
  • The list of masks above does not appear to be totally complete. PDF files were encrypted and were not originally part of the set of file masks. That is the only exception I noticed, everything else follows the list. Conveniently (/s), CryptoLocker has a button you can click that shows the list of files it's encrypted.
  • The current ransom is $300 by MoneyPak or 2BTC, which at the time of writing would be $280 and change.
  • Fabian reported that registry data is stored at HKCU/Software/CryptoLocker. I cannot glean the meaning of the DWORD values on files but I do notice they are unique, likely salts for the individual files. I'm curious what purpose that would serve if the private key was revealed as the salts would be useless.
  • I have confirmed the message soulscore left that setting the BIOS timer back a few hours adds an equal amount of time. No telling whether that will work once it has a network connection and can see the C&C server, though.
  • The virus walked right through an up-to-date version of GFI Vipre. It appears AV companies either consider the risk too low to update definitions or, more likely, they're having trouble creating heuristic patterns that don't cause a lot of collateral damage.
10/11 EDIT: I ran Daphne on the infected PC to get a better idea of what might be going on. lsass.exe is running like crazy. Computer's had it's CPU pegged all day. I noticed the primary executable running from %AppData% has a switch on the end of the run command, which in my case is /w000000EC. No idea what that means.
10/15 EDIT: I just wanted to thank all the redditors that have submitted information on this. I have some interesting new developments that I'll be editing in full tomorrow.
10/18 EDIT: Hello arstechnica! Please read through comments before posting a question as there's a very good chance it's been answered.
New developments since 10/15:
  • We have confirmation that both Malwarebytes Antimalware Pro and Avast Free and Pro will stop CryptoLocker from running. My personal choice of the two is MBAM Pro but research on your own, AV Comparatives is a wonderful resource.
  • We have reports of a new vector of infection, Java. This is hardly surprising as Zeus was already being transmitted in this fashion, but Maybe_Forged reports contracting the virus with a honeypot VM in this manner.
  • zfs_balla made a hell of a first post on reddit, giving us a lot of insight to the behavior of the decryption process, and answered a frequently-asked question. I'm paraphrasing below.
A file encrypted twice and decrypted once is still garbage.
The waiting for payment confirmation screen stayed up for 16 days before a decryption began, so don't lose hope if it's been up a while.
The DWORD values in the registry have no bearing on decryption. Renaming an encrypted file to one on the list in the registry will decrypt it. However, I would presume this would only work for files that the virus encrypted on that machine as the public key is different with every infection.
Adding any new matching files to somewhere the virus has access will cause them to be encrypted, even at the "waiting for payment confirmation" screen. Be careful.
Hitting "Cancel" on a file that can't be found doesn't cancel the entire decryption, just that file.
EDIT 2: I've rewritten the bulk of this post so people don't have to slog through edits for important information.
10/21 EDIT: Two noteworthy edits. One is regarding Carbonite, which is apparently a viable backup option for this, it is covered under File Recovery. The other is regarding a piece of software called CryptoPrevent. I have not tried it, but according to the developer's website it blocks %localappdata%\*.exe and %localappdata%\*\*.exe which is not necessary for the current variant and will inflict quite a bit of collateral damage. I have no reason right now to doubt the legitimacy of the program, but be aware of the tradeoffs going in.
I'm now at the 15000 character limit. Wat do?

Usage

Helix has numerous features. Remember that this list is not limited, and that we will always work hard to add new features:
  • Fast and secure transactions.
  • Strong privacy with options for both private and transparent transactions.
  • Rewards for participating in the Helix network. This includes Proof of Stake (PoS) as well as the possibility for masternode rewards.
  • Participating in governance and voting in important matters that concern the whole community.
  • Multi-OS wallets: Windows, MacOS, Linux, and many more to come.
  • Very easy access to all our features and wallets.
  • We will continue to work hard on making Helix grow, check out our roadmap for details.
We believe in empowering individuals by creating a strong community. We give freedom back to the people by using our strong Helix blockchain network and decentralized technology. This allows people to do business without the compromise of being subject to surveillance by centralized or legal institutions.

​Proof of Stake

Bitcoin uses a cryptographic hashing algorithm to encode the transactions in the blockchain. Miners create these hashes by using a ‘Proof of Work’ (PoW) algorithm. The network hashrate is actually inflating as it requires a lot of power to create a new block in its blockchain.
Unlike Bitcoins PoW mechanism, Helix blockchain uses a hybrid system. The first 90.200 blocks are PoW, and after this period we switch to a PoS mechanism. The rewards a user receives depends on the amount of stake the participant has in the Helix network. The more you participate in validating and processing Helix transactions and its blocks, the more rewards you receive. Therefore, it’s incentivized to invest in Helix as a valuable core product.

Masternodes

The value of Helix lies in its main vision: building a secure and scalable currency. Therefore, Helix implemented masternodes, which can be used to earn more Helix by passive income to increase your holdings with a great risk/reward ratio. A masternode costs 10.000 HLIX and gives a ROI of 60%.
Masternodes are enhanced nodes that are always up and running, which provide additional functions and security to the Helix network. Masternodes provide an enhanced form of staking, increase the privacy and speed of transactions and enables participation in governance and voting within the Helix community. A Helix masternode processes Zerocoin (zHLIX) transactions which ensures topnotch privacy (more about this subject under ‘Privacy’).

Privacy

Helix believes in true and strong privacy. Bitcoins transactions are traceable for anyone who’s interested to find out. A high degree of privacy doesn’t allow this potential loss of privacy. That’s why Helix implemented the Zerocoin protocol. For detailed information about Zerocoin, read their whitepaper.
For this service, Helix coins have to convert into a zHLIX coin. This process, called ‘minting’, is provided by masternodes running on the Helix Blockchain. No traces are left behind during this process. RSA-2048 encryption makes sure no information about the users is shared whatsoever. To reverse this process, you can send your zHLIX coins to your own address back into regular HLIX coins.

Coin information

Helix is founded on September 1st 2018. A total coin supply of 500.000.000 HLIX will be created, with a functional pre-mine of 1% (5.000.000 HLIX). This will be used for marketing, development and exchange listing fees. The first period will exist of a PoW phase (10.000.000 HLIX), followed by a PoS phase (485.000.000 HLIX).

Community

The community started with a couple of early adopters who were unhappy about the way some projects were run by its developers. No innovation or vision whatsoever made us motivated to create something better. Since Helix did not have an ICO and only started with a functional pre-mine of 1%, it’s really thanks to the true core believers who put in their time and effort that made Helix a reality.
We aim to provide 24/7 support, and we believe in a community who help each other out. Positivity and fun should be your top priority as a Helix community member. In accordance to this, we created the Helix masternode governance system to bring back the power to the people. By letting you decide on important matters, you’re in control of your investment.

Join us!

More people are joining every day and we hope this growth won’t stop. Don’t feel afraid to join us and introduce yourself. We’re looking forward to meet you!
With the upcoming years ahead of us, we believe that exciting things will happen. Helix is a premium privacy ¬centric cryptocurrency, with strong features resulting in a decentralized, effectively anonymous cryptocurrency, with immediate (private) transactions and an incentivized network to provide additional services and security to the blockchain network of Helix. We will continue to work hard on the project, and hope to see you join us.

My office just got hit with a BTC encryption ransom

Here is the text: every file in folders on one drive has been encrypted, and this .txt file has been included in every folder:
  1. This is funny
  2. Is there any workaround for this? Has anyone else encountered this?
Again, the text is below:
All your documents, photos, databases and other important files have been encrypted with strongest encryption RSA-2048 key, generated for this computer.
Private decryption key is stored on a secret Internet server and nobody can decrypt your files until you pay and obtain the private key.
If you see the main encryptor red window, examine it and follow the instructions. Otherwise, it seems that you or your antivirus deleted the encryptor program.

General info and list of exchanges for Paymon (PMNT)

What is Paymon? Conversion and withdrawal of cryptocurrencies in only 2 clicks. Advanced encryption system. Ability to communicate with others. Unique game platform. Who is Paymon for? For those who want to transfer money to friends and relatives anywhere in the world. For those are fed up with the current banking system. For those do not want to pay fees to the intermediary parties. What is Bitcoin? Decentralised currency (a currency which is not managed by any single bank, company or state, allowing complete anonymity of users' transactions). Anonymous system (data is encrypted with the help of blockchain). A currency that is not limited by just one country, it can be used anywhere in the world. How is Paymon different from other payment systems? Paymon is operating on a blockchain system, it works only with cryptocurrencies. You can convert cryptocurrencies to fiat. You can exchange cryptocurrencies with people from all over the world. Anyone can use Paymon platform. Paymon is a user-friendly platform. Are there any commissions? In each transaction you are the one to set the commission. The higher it is, the faster is the transaction. This feature is available only for Bitcoin transfers.
Bitcoin: - The recommended minimum commission for Bitcoins transfers is 0.0005 BTC.
Ethereum: - The Commission depends on the network load and is not usually more than 525000 Gwei (~0.18$)
How to conduct a transaction? Paymon creates a Bitcoin wallet attached to your personal account automatically, once you register in the system. You can also create an Ethereum wallet or restore it from the backup copy. These wallets are in the Blockchain system and only you have access to them. The added fiat funds are automatically converted to cryptocurrency. In order to conduct a transaction, you need to go to the “Money” tab in our application, then enter a wallet’s address. Or you can simply find the user in your contacts list and press “Transfer” in the dialog window. Addition and Withdrawal. Important!
Please do not add or withdraw funds in any ways other those that are in Paymon. Conducting such operations through intermediaries might cause you substantial losses. In order to add funds, you need to go to the “Money” tab in our application and click “Add”. Thus to withdraw click “Withdraw”. Commission is individual for each transaction. Who will have access to my personal information and wallets? Only you Can I add already existing cryptowallets? You cannot have two of the same cryptocurrency wallets, but you can add other wallets. - JSON format for Ethereum.
How to make a wallet cold? What is a cold wallet? This feature is not available for Bitcoin wallets. You can make a backup copy of the Ethereum wallet and then “delete” it. Thus making it cold. With the help of a cold wallet you will be able to keep cryptocurrency on physical carriers. They don’t have access to the Internet, which means that hackers won’t be able to reach it.
What makes the correspondence secure? We use our own Protocol in the application. All traffic is encrypted with Diffie-Hellman and AES (Advanced Encryption Standard) using SHA (Secure Hash Algorithm). All correspondence is encrypted with RSA-2048.

Bitcoin2. zBTC2 Data Integrity

Every minted zBTC2 denomination is associated with a unique serial number that is stored in the local wallet.dat and not on the blockchain. This means that when a new zBTC2 denomination is minted, the wallet.dat should be backed up as the previous backup will not have the serial numbers for the newly minted zBTC2 denominations.
The serial number and other essential zBTC2 data are committed to the database (wallet.dat) before the transaction is completed and broadcasted to the network. This minimizes the risk of losing your freshly minted zBTC2 denominations during an unexpected event during the minting of zBTC2, such as a PC crash or internet connectivity issues.
Due to its local database design, it is imperative that your wallet is backed up after every new zBTC2 mint to ensure that your denomination serial numbers are up to date.
Technical Specs (in Bitcoin 2 Core v2.0)
Key Features: Custom accumulator checkpointing system
Accumulator Encryption: RSA-2048
zBTC2 Denominators: 0.05, 0.2, 1, 5, 20, 100, 500, 2000
Mint time: >= 0.5 seconds Spend time: >= 2.5 seconds
Maximum single Spend limit: 34,000 BTC2
Maximum single Spend denomination count limit: 17
Maximum block size: 4 MB
Fees (mint): 0.001 BTC2 per minted zBTC2 denomination.
Fees (spend): No fee to spend zBTC2 back to BTC2. (In other words no fee to send zBTC2.)
Minimum BTC2 confirmation count required to mint zBTC2: 6
Minimum zBTC2 confirmation count required before spend: 20
Maturity requirement before zBTC2 can be spent: 1 new identical denomination mint added to accumulator after yours is added.

Everyone’s privacy is ensured through the use of zBTC2

An address may seem like it is fully anonymous but if you made a transaction with an address that is generated by the exchanges and/or other merchant services, you have essentially linked your anonymous address with an address that may lead to your identity. Such transparency may not always be an issue. But it could become a serious problem if the coin that you hold was once associated with an undesirable history or if your address was being targeted by potential thieves. To overcome this issue, Bitcoin 2 has implemented a well known highly-vetted protocol called Zerocoin with many custom enhancements allowing blockchain-level transaction anonymity in the way of unlinkability. What zBTC2 provides is a protocol-level coin mixing service using zero knowledge proofs to sever the link between the sender and the receiver with 100% anonymity and untraceability. This means that each coin that gets sent using zBTC2 is now 100% fungible as it has no determinable history attached to them. Bitcoin 2 zBTC2 accumulators are encrypted using RSA-2048[1] challenge generated keys which negates the need for a developer trusted setup and means that no individual knows the factors. This means that everyone’s privacy is ensured through the use of zBTC2. The use of zBTC2 also means your balance can be masked to avoid being targeted by potential thieves. This is a very unique feature that nearly no other cryptocurrency currently in the market possesses.

Faking a BTC transaction to trick a cryptolocker

There's this computer here that was locked by CryptoWall - a piece of malware which encrypts files with a certain extension (mostly important documents, photo's etc) with a 2048-bit RSA key while they securely store the private key on their servers.
The programmers are using bitcoins to take ransom for the files and that's the reason I've started this question.
Would it be possible to create a fake transaction to trick the CryptoWall system to think they have paid, even though the transaction hasn't been verified? I could imagine them not really taking the time to actually accurately check if a transaction has had its verifications. Though, I'm not sure obviously as I'm not an experienced cryptocurrency user.
Thoughts? Input? :)

Digital Artist: Back Up Your Artworks on an unattached external storage now.

This September seems to be the peak epidemic period of Cryptowall Ransomware and all of its numerous variants.
CryptoWall is a file-encrypting ransomware program that was released around the end of April 2014 that targets all versions of Windows.
When you are first infected with CryptoWall it will scan your computer for data files and "encrypt" them using RSA-2048 encryption so they are no longer able to be opened.
There is no known utility to decrypt RSA-2048 encryption without the private key held as ransom by the evil virus writer. Brute force decryption approach would take around 100 years to decrypt a file.
Once the infection has encrypted the files on your computer drives it will open a Notepad window that contains instructions on how to access the CryptoWall Decryption Service where you can pay a ransom to purchase a decryption program.
The ransom cost starts at $500 USD and after 5 days goes up to $750 with the cost increasing again after another 24 hours to a maximum ransom of $1,500 USD. This ransom must be paid in Bitcoins and sent to a Bitcoin address that changes per infected user.
Besides your local hard drives, it attacked all mapped network drives and all external storage devices attached to your computer (flash drive, USB external hard drive, thumd drives, USB sticks... everything You name it). This virus also encrypted files on your Cloud backup such as Dropbox drive or Google drive too.
It slips by Anti-virus and anti-trojan software on your pc without any detection (The new CryptoWall samples were not detected by any of the 55 antivirus products used on the VirusTotal website when they were discovered Sunday), so more often than not when You found out about the virus, all your files on all your drives have already been encrypted.
Some digital artists have lost all their artworks by not having a reliable unattached incremental back ups or having an unreliable external backup drive which was attached to the pc at the time so the back up was also encrypted.
All your personal documents and artworks could be wiped out in around 2 hours. On the average it takes only around 2 hours to encrypt a 2 terabyte drive.
Please digital artists, back up all your artworks on a reliable external hard drive and disconnect it from your computer after a successful back up and store it in a safe place.
Info about this scary virus
Regards,
:)
DL ( I have just lost all my drawings without backup) :)

Some best practice advice please. Bought a second key (v4) and want to start using it/them in anger. (Long-ish but simple questions).

(I'm labelling so that you have easy ways to refer to shite - not for any real reason. By way of background, I'm not dedicated IT but reasonable competent - just beyond that little knowledge is dangerous phase; I'm involved in law, tech and finance for my sins). I'm running Linux - reasonably competent.
I saw ECC keys have been nixed by the NSA but I think that's where I want to go anyway. Will review the decision when I review the subkeys.
a. I have an older yubikey-neo v3 (2048/RSA max) and a newer nano 4. The v4 is effectively virgin.
b. v3 Neo: I have been using slot 2 as a static password and the U2F for GitHub. I need to start using my yubikeys properly.
c. Can I copy different versions of the key content between versions? Couldn't see it on the neo-manager or personalisation progs. How do you manage your backup/primary keys? (didn't see much on the net about them). Guess masterkeys stay safe on USB somewhere and just copy the masterless subkeys to the two yubi's?
d. I think I want to start using my old yubikey as the backup. I don't have a problem yet with the smaller key length implementation on the v3 vs v4. Lawyers email stuff as plain text ..! I'm not doing anything super wonderful, it's the client stuff locally not being quite best practice I worry about.
e I need to create replacement SSH keys around. Usual thing: cloud-based and real servers. They're in a mess on my HD at the moment. I know I experimented with ECC keys a while back but don't have proper notes.
f. I guess I should create a few. Key Key risk ..? Is ECC a thing for sshd, widespread/debugged? (suggestions, tips etc, best practice)
g. I desperately need to up my PGP game. I have none worthy of the name. Again, is PGP ECC widespread/debugged enough to use them (as much as pgp is widespread :) ). Openpgp is a reasonable version number now.
h. I'd like to sign stuff emails, git for the moment. File encryption is OK with basic LUKS - haven't investigated tying that to PGP or such.
i. My biggest problem here is the sodding yubikey docs. I don't find them very good at all. Perhaps it's just me, but the net is ok.
j. I can't find a PGP email client I like. Decided finally last week not to try to build a mail server (for PGP signing) myself and just go with zoho on DO.
k. I'm investigating accepting bitcoin payments, but know nothing about blockchain/bitcoin. Views on using yubi with that? don't expect to keep a balance, and close out the FX risk ASAP; much bid-offer spread on bitcoin?
Links appreciated. I have gather far too many and am confusing myself about best practice ATM.
Thank you all very much for whatever time you can spend deciphering this (pun intended).

New Ransomware - not petyr clone - hitting companies in eastern europe

This is the best tl;dr I could make, original reduced by 67%. (I'm a bot)
Another ransomware assault is spreading across eastern Europe and has officially hit more than 200 noteworthy associations, essentially in Russia, Ukraine, Turkey and Germany, in the previous couple of hours.
Named "Bad Rabbit," is apparently another Petya-like focused on ransomware assault against corporate systems, requesting 0.05 bitcoin as payment from victims to open their systems.
Bad Rabbit ransomware utilizes DiskCryptor, an open source full drive encryption programming, to encode documents on PCs with RSA 2048 keys.
ESET trusts the new rush of ransomware assault isn't utilizing EternalBlue code - the leaked SMB vunerability which was utilized by WannaCry and Petya ransomware to spread through systems.
Specialists are as yet examining Bad Rabbit ransomware to check if there is an approach to decode PCs without paying ransomware and how to prevent it from spreading further.
Most ransomware spread through phishing messages, malware adverts on sites, and 3rd party applications.

How many qubits would it take to break Bitcoins SHA 256 bit encryption?

INFORMATION I GATHERED
Where are we at? 512 qubit computer ... But these are low quality qubits mainly due to issues with sufficient isolation from our universe, getting clear readings, and speeding up the gates. Also Dwave computers are currently limited in a way that supposedly does not have the capability for encryption cracking
If the qubits worked optimally how much does it take to break existing encryption? 2048-bit RSA requires roughly 4096 qubits while a quantum computer to break the equivalently secure 224-bit Elliptic Curve Cryptography requires between 1300 and 1600 qubits Yes this is not bitcoins 256 bit, nor the same math, but its the closest information I could reasonably find.
The NSA is preparing to make a computer that can crack any currently used difficult encryption except types that are quantum protected like the new Lattice encryption. When the NSA is done it will be able to crack Bitcions SHA256 private keys using the public. Right now they are currently working with a 2 qubit computer to do testing before the production implementation
Remember those /bitcoin frontpage posts about how cracking bitcoin would require a computer the size of the universe? Check out this excerpt about a 300 qubit computer "The projected performance of this new experimental quantum simulator eclipses the current maximum capacity of any known computer by an astonishing 10 to the power of 80. That is 1 followed by 80 zeros, in other words 80 orders of magnitude, a truly mind-boggling scale," Dr Michael Biercuk, at the University of Sydney, said. "[It] has the potential to perform calculations that would require a supercomputer larger than the size of the known universe - and it does it all in a diameter of less than a millimetre.
Adding to alarm is that quantum computers double in their ability to calculate with every qubit. In general, a quantum computer with n qubits can be in an arbitrary superposition of up to 2n different states simultaneously To build more powerful quantum computers, though is currently restrained by the quality of the qubit. If you read the timeline of quantum computing advancements you will see progress is being made on this at a decent pace though. Once we have a clean method down, the multidimensional sky is the limit.
Yes the rest of the banking industry is also largely vulnerable if such a quantum computer was made, as they also use common public key encryption.
Another caveat is that bitcoin uses 2 encryption methods. SHA256 for mining. Elliptic Curve for relating the pubic keys and private keys.
QUESTIONS FOR BITCOIN
Ok so, that is what related information I could find.
Yes I realize there is plenty of material written about how bitcoin code can be updated, or other reasons quantum computers are not a concern, but the point here is that the community needs to know about when this risk will happen and be prepared. It could be sooner or further away than we expected and everyone's finances should not be caught off guard. This post is about when bitcoin should expect a risk, not gauging the risk (unless it is zero)

Web Hosting Company Pays $1 Million to Ransomware Hackers to Get Files Back. They were running Linux 2.6.

This is the best tl;dr I could make, original reduced by 49%. (I'm a bot)
South Korean web hosting provider has agreed to pay $1 million in bitcoins to hackers after a Linux ransomware infected its 153 servers, encrypting 3,400 business websites and their data, hosted on them.
According to a blog post published by NAYANA, the web hosting company, this unfortunate event happened on 10th June when ransomware malware hit its hosting servers and attacker demanded 550 bitcoins to unlock the encrypted files.
The company later negotiated with the cyber criminals and agreed to pay 397.6 bitcoins in three installments to get their files decrypted.
Since the hosting servers were running on Linux kernel 2.6.24.2, researchers believe that Erebus Linux ransomware might have used known vulnerabilities, like DIRTY COW; or a local Linux exploits to take over the root access of the system.
"Additionally, NAYANA's website uses Apache version 1.3.36 and PHP version 5.1.4, both of which were released back in 2006." Erebus, the ransomware primarily targeting users in South Korea, encrypts office documents, databases, archives, and multimedia files using the RSA-2048 algorithm and then appends them with a.ecrypt extension before displaying the ransom note.
"The RC4 key is then encoded with AES encryption algorithm, which is stored in the file. The AES key is again encrypted using RSA-2018 algorithm that is also stored in the file."

Combating Cryptolocker with Python Script?

My mom's PC has been infected with a nasty Trojan called Cryptolocker.
Her small business docs are on the PC, and she's not going to pay the $400 in bitcoin they demand. Here's some info about the Trojan taken from another post
CryptoLocker encrypts a set of file masks on a local PC and any mapped network drives with 2048-bit RSA encryption, which is uncrackable for quite a while yet. WinXP through Win8 are vulnerable, and infection isn't dependent on being a local admin or having UAC on or off. MalwareBytes Pro and Avast stop the virus from running. Sysadmins in a domain should create this Software Restriction Policy[8] which has very little downside (you need both rules). The timer it presents is real and you cannot pay them once it expires. You can pay them with a GreenDot MoneyPak or 2 Bitcoins, attempt to restore a previous version using ShadowExplorer[9] , go to a backup (including versioning-based cloud backups), or be SOL.
This is the Python code I think may solve the issue. I have no idea how to impliment it though. My total knowledge of Python is taking the intro course a couple months back from CodeAcademy.
The timer runs out in 90 hours. I really need help, guys.
