Cryptography news and discussions

Cryptography is the art of creating mathematical assurances for who can do what with data, including but not limited to encryption of messages such that only the key-holder can read it. Cryptography lives at an intersection of math and computer science. This subreddit covers the theory and practice of modern and *strong* cryptography, and it is a technical subreddit focused on the algorithms and implementations of cryptography.

Cryptomessengers: Effective Mix of Privacy and Add Values

Time is fleeting.
It seems like yesterday to make a transaction or receive the money we had to go to the banks, stand in queues, experience technical issues which caused a delay in the whole process. And we can not omit the human factor -the incorrectly filled bank form. Missing data. Problems with requests processing due to the large volumes of data. Or incorrect structuring of huge data arrays. All these things cause the impossibility of conducting immediate operations and irritate people deeply.
But fortunately, things have changed.
With the explosive growth of mobile devices and payment services, there is no need for all this mess. Mobile devices give infinite possibilities. In fact, you have a most powerful tool to the well of unlimited information. Every year we dive deeper into it. (And we all are familiar with the words of N. Rothschild “Who owns the information, he owns the world.”) With a portable computer in your pocket, you stay on the edge of the technological wave and keep up-to-date with all innovation breakthroughs.
Our world is digitized. Everything you’ve struggled to know is within arm’s reach. The development of mobile technologies and improving the quality of the mobile Internet enable businesses to conduct transactions anytime anywhere.

Problem or Opportunity?

In 2019 the number of mobile phone users is forecasted to reach 4.68 billion.
By the end of 2019, it is expected to pass the five billion mark.
The entire world is currently about mobile phones, not computers.
This idea of paying for your goods with your cell phone is becoming much more widespread mainly due to the consumer’s need for greater convenience. This trend has been further encouraged by the launch of popular mobile payment gateways such as Apple Pay, Google Pay, Samsung Pay.

Data Security Issues and Сonsumer Rights Protection

The enormous amounts of data received every day in various infrastructures need to be regulated and protected.
The user wants to surf the internet safely, buy products safely.
Sensitive information should remain confidential.

Biometric Payments and Payments with Selfie

The first publicly available device with a fingerprint sensor was Motorola Atrix, which launched in 2011.
Daily life tasks become more and more automatized. The next step seemed to be the payment with a selfie, fingerprint, or retinal scan. Biometric payments are expected to be the future disruptive technology in the mobile payment industry. According to the overview of Mobile Payments Industry made by PRIME INDEXES, biometric payment system works by analyzing unique biological traits of a person, such as DNA, fingerprints, or facial features. The use of a fingerprint and a facial scan has already become the mainstream for unlocking smartphones. Due to the convenience and security that biometrics provides, it is expected to replace traditional digital identification schemes on a global scale.
Acuity Market Intelligence forecasts that, by 2022, there would be over 5.5 billion biometrics-enabled mobile devices processing over 1 trillion transactions annually, driving the market’s annual revenue to $50.6 billion. There are lots of concerns about fingerprint scanners and other biometric unlocking methods. One of them is that if someone steals your biometric identifiers, you won’t be able to change them like a password, making them permanently compromised. The other idea is that if a security method is more comfortable for the user, they’ll be more likely to use it, and biometrics are better for security in general.

Regulations of e-cash and security

Electronic payment systems are not new. Electronic Funds Transfer has been in use since the middle of the last century. Online credit and debit card systems are also electronic. But, these transactions are managed through closed commercial networks, and the main obstacle is wire fraud. Their security intensified using encryption — The Enigma cipher machine was based on this technology. In contrast, the Internet is an open system, which makes security much more of a problem. The challenge is to develop open systems that are secure, convenient and cost-effective over a range of micro- to-macro-transactions. Anonymity would also be a commercial advantage for many types of internet transactions.
How do these new systems obtain these criteria? It remains to be seen.

Bitcoin & Blockchain Technology

The blockchain sector focused on finance will grow from 250 to 350 million people by 2025. People usually confuse Bitcoin with Blockchain. Bitcoin was the first-ever application of Blockchain. Since then, Bitcoin has had technological advancements and now satisfies other industries as well. Bitcoin is a cryptocurrency. It is not institutionalized, though people around the world use it for various kinds of payments and transactions. As far as it is not physically present, it is very safe and secure, and blockchain is the best mediator for these transactions. The underlying idea was in its anonymity. And that Bitcoin would reduce the cost of transactions, lower the cost of influencers, would have no restrictions by government and will be limited in quantity.
The blockchain is a type of a ledger that can record all the transactions and assist in peer-to-peer transactions. It is open, secure and easily accessible to everyone. Blockchain can transfer anything, from currencies to property rights of stocks. Blockchain acts as bitcoin’s ledger and takes care of all the transactions of bitcoin. The technology of blockchain is more open to changes, and thus, has the backing of many top companies. Since then blockchain is in constant capacity-building, and now it is catering to even small transactions across various industries.
Bitcoin, the decentralized network, allows users to transact directly, peer to peer, without a mediator to manage the exchange of funds. Bitcoin is based on a P2P (Peer-To-Peer) network system. Hence, everything relies on good communication between peer nodes.
Some of you already know very good a Telegram- a cloud-based instant messaging and voice over IP service developed by Telegram Messenger LLP). The company also announced its intention to make a custom crypto wallet integrated into the app.

The first in the world & Crypto Community

Elvn team in partnership with Dashdevs crew had decided to develop a solution that will be able to combine all the existing useful features with technologies of the future.
Elvn, first of all, has a vision of how to develop and grow the crypto community. The crypto community initiated in 2009. According to the study, data show that in the first three quarters of 2018 the number of ID-verified cryptocurrency users nearly doubled, climbing from 18 million to 35 million. Despite its small quantity, by the end of 2018, the crypto community managed to generate 400 billion dollars in capitalization. The Elvn team started wondering what happened with crypto capitalization if there were 150 million active users instead of 35 million? An example to compare, the instant messenger Telegram has globally 200 million active users.

Crypto Wallet

Estimate: 3 weeks
Purpose: Add/send/receive money to the wallet/check
Elvn in partnership with DashDevs created the first crypto messenger in the world bringing a messenger and crypto community together.
The primary purpose of this innovation is to implement the brand new way of communicating with advanced capabilities.
This innovative mobile application has an in-built crypto wallet. Thus you can easily manage your digital money in one place.

Privacy

We have made Elvn a convenient and safe app for communication.
The whole project proceeded in an accelerated mode. We were very pressed for time. Thus, we adopted decisions rapidly but wisely.
Crypto wallet in the application was based on SPV (Simple Payment Verification).
By default, when receiving a new transaction, a node must validate it. In particular, verify that none of the transaction’s inputs has previously spent. To carry out that check the node needs to access the blockchain. Any user who does not trust his neighbor networks should keep a full local copy of the blockchain so that any input can be verified. With the implementation of symmetric encryption AES, there was ensured high-level security for encrypting the private key.
We have enabled the creation of a new wallet immediately after registration. In a case when you log into the app, and you already have a wallet, a new one will not be generated. A user can add the public key of the wallet to the user’s profile. In this case, other users can see the public key. While a private key, on the contrary, is securely encrypted. To decrypt this private key, a user has to enter the PIN code.
The copy of the wallet (a private key) is stored only in the phone storage. And after installing the PIN code, it is no longer stored in the phone (the private key is encrypted and can be decrypted using the PIN code). In case when you need full access to your wallet (to send money for example), it is always restored from these parts.
A private key (of your wallet) is required to send (sign) a transaction. Thus, the recipient needs only the address of the wallet. You can manage the resources of your wallet only if you have a private key. And private key never passes to anyone. But, you can check your balance using the public key.
We tested the transfer of coins using a bitcoin test network.
The most challenging was to implement the best-fit solution for the messaging part of the application. In our case, it was MTProto (a cryptographic protocol used in the Telegram messaging system to encrypt user communications).

A great solution for any business

We have made Elvn not only a users’ tool but also a great business solution.
With the help of Elvn mobile application, it becomes possible to attract more people to the crypto community.
Elvn is confidential so that everyone can conduct the business dealing via this mobile tool. Moreover, you can send an unlimited amount of your files of any type, such as doc, zip, pdf, images, voice records, and videos.
Additionally, Elvn also has a social network in which you can add up to 100,000 friends, whose posts can also be encouraged by the incentive of earning cryptocurrency.
We made it easy to support the favorite content by a simple “like.” You can also send coins to the author of the “liked” post with just one click.

DashDevs

📷
The DashDevs team, together with the Elvn team created a unique crypto messenger, which combined both communication and business purposes.
Being limited by time, DashDevs took all the best solutions and put them in one app. And yes. Nobody has done this before.
The DashDevs team does not feel afraid to challenge the most difficult and innovative ideas and put them into practice.
We stand on the solid foundation of our expertise and are ready to build a new future full of new business opportunities with you.
Our Sci-Tech Crew has strong expertise in developing diverse projects, for both ordinary customers and various complex solutions for businesses.

Question, is there a timetable for the Lightning Network?

I know there is a beta running on testnet3 (the Bitcoin Test Network) and I know they are close to fully implementing the Lightning Network specification (BOLTs) but I haven't been able to find a time table or time estimate for all this.

One input to the dollar price of Bitcoin is how much people are willing to pay Miners to secure the network... the halvening is a recurring event every four years (until 2140) that tests the Miners ability to set prices to secure the network.... other factors are at play, but this point is crucial

How much are willing to pay to maintain the hash power of the Bitcoin network?

Why would Litecoin users want SegWit?

[I tried to post the following to /litecoin, but it was blocked.]
[Disclaimer: I am a prof of computer science who is a longtime cryptocurrency skeptic and a regular contributor to /buttcoin]
SegWit was developed by Blockstream for their own reasons, without any input or demand by the bitcoin community, and was included in the Core release (pending 95% miner approval) even though it was by far the most controversial change that got that far.
Blockstream tried to justify SegWit by saying that (1) it would fix the "malleability bug" that stood in the way of the Lightning Network (LN); (2) it would fix the "quadratic validation cost" bug; and (3) it would increase the network's capacity by some 70%, relieving its present congestion.
For Bitcoin, it is possible to argue that those justifications are bogus: (1) there is not even a viable sketch of the LN yet, so the malleability bug is not an urgent issue, and anyway it can be fixed in a much simpler way; (2) ditto for the quadratic cost bug; and (3) a 70% increase will not make the network any less congested. Thus the actual benefits of SegWit do not justify it complexity, disruption, and risks.
For Litecoin, on the other hand, no arguing is needed. The congestion of Bitcoin was artificially and intentionally created by Blockstream. The Litecoin network is far from congested, so it will not even need a Lightning Network any time soon. There is no justification for SegWit in it.
The proposal to implement SegWit in Litecoin was not motivated by a desire to improve the coin. The goal was obviously to expĺoit Litecoin users as guinea pigs in a field test of SegWit, for Blockstream's benefit.
Such a test was needed because, even though SegWit has been tested by some developers on Bitcoin's test network, there is a non-negligible chance that nasty bugs will appear when it is exposed to real use patterns by general users -- including malicious ones, who obviously have no motivation to waste their attacks on the test network.
If that happens, the reasoning went, it is better that it happens to Litecoin than to Bitcoin...
So, I wonder: why are some Litecoin users so fanatically supportive of SegWit that they advocate obviously destructive measures like UASF or changing the PoW, just to get it?

The tech is not crap, Iota is faster, cheaper and does not require mining. The whole PoW Consensus is old tech and will eventually be replaced by newer generation solutions. Yes they have had their problems, its a relatively new project but that does not mean they are a scam or have bad tech.
