What is cryptography? Who are the cypherpunks?

1 What is cryptography? Cryptography is the science of methods that ensure data authentication, integrity and confidentiality. 2 When did cryptography emerge and how did it evolve? As a technique for protecting text, it arose alongside writing—methods of secret writing were known in ancient India, Mesopotamia and Egypt. In the first period of development (roughly from the third millennium BC to the ninth century) monoalphabetic ciphers predominated […].

What is Zcash (ZEC)?

1 What is Zcash (ZEC)? Attention! The article is outdated and awaiting an update. Zcash is a peer-to-peer payments system with a native unit of account. 2 Who created Zcash, and when? Creators: cryptographers Matthew Green, Ian Miers, Christina Garman, Avi Rubin, Eli Ben-Sasson, Alessandro Chiesa, Madars Virza and Eran Tromer (developers of the base protocols Zerocoin and Zerocash). Development is handled by the for-profit Electric Coin Company…

What is crypto‑anarchism?
ForkLog 22 03.04.2020

What is crypto‑anarchism?

1 What is crypto‑anarchism? Crypto‑anarchism is a strain of anarchism that uses cryptographically secured anonymisation technologies, digital pseudonyms and digital money to bypass state controls—surveillance, censorship and taxation. 2 How did crypto‑anarchism emerge? In the 1940s Western intelligence agencies explored involving recipients in the encoding process. In 1973 British mathematician Clifford Cocks presented a model for public‑key cryptography, later realised in 1977 as RSA by three MIT professors.

What is Grin?
ForkLog 26 27.12.2019

What is Grin?

Grin is an open-source cryptocurrency built on MimbleWimble. It emphasises enhanced privacy, a compact blockchain that scales with users, a donation-funded launch without a premine or ICO, and mining via the Cuckoo Cycle PoW algorithm.

What is Beam?

What is Beam?

1 What is Beam? Attention! The article is outdated and requires updating. Beam is a privacy-focused cryptocurrency built on the MimbleWimble protocol. 2 How and when did the Beam cryptocurrency emerge? In March 2018 a team assembled by Israeli programmer and entrepreneur Alexander Zaidelson under Beam Development Limited began work on Beam. Most of the company’s staff are from post-Soviet countries. Ten months later—on January 3, 2019—the mainnet launched. Beam was the first implementation of MimbleWimble; twelve days later the second working implementation, Grin, went live, though its development had started a year earlier.

What is MimbleWimble?

1 What is MimbleWimble? A PoW protocol offering broad scalability and enhanced privacy; in the Harry Potter novels it is the "tongue-tying curse", hinting at concealed transaction data. 2 Who created it and when? An individual or group using the pseudonym "Tom Elvis Jedusor"; a white paper appeared on July 19, 2016, followed by Andrew Poelstra’s review in October and an early Grin implementation soon after.

What is the Dash cryptocurrency and how does it work?

What is the Dash cryptocurrency and how does it work?

Dash is an open-source peer-to-peer payment system with its own unit of account. Launched on January 18, 2014 by American programmer Evan Duffield as Xcoin, it was later renamed Darkcoin (2014) and DASH (2015). A bug during the fork led to an instamine of 1.8m DASH. The network features masternodes, PrivateSend, InstantSend, a block-reward split with 10% to a development fund, and voting on dash.org. The article is outdated and requires updating.

What is Monero (XMR)?

What is Monero (XMR)?

1 What is Monero? Attention! The article is outdated and requires an update. Monero (XMR) is a privacy-focused cryptocurrency with open-source code, whose protocol implements several transaction-anonymisation techniques: stealth addresses and ring confidential transactions. On the Monero network, only the transacting parties—and anyone given a special access key—can see the amount and the sender and recipient addresses. 2 Who launched Monero, when and how?

How Bitcoin transactions are tracked
ForkLog 17 05.09.2019

How Bitcoin transactions are tracked

Bitcoin addresses are alphanumeric and pseudonymous, but every transaction is recorded openly, making activity traceable. Block explorers let anyone view balances, TXIDs and flows, while privacy tools such as CoinJoin provide only partial cover. For deeper, faster work, firms including Chainalysis, Bitfury’s Crystal and Elliptic sell analytics that link addresses, visualise flows and flag risks for exchanges and law enforcement.

What is a zero-knowledge proof?
ForkLog 28 21.05.2019

What is a zero-knowledge proof?

A zero-knowledge proof is a cryptographic protocol that lets a prover convince a verifier that a statement is true without revealing any additional information about it. The notion was first proposed by MIT researchers Shafi Goldwasser, Silvio Micali and Charles Rackoff in the 1985 paper The Knowledge Complexity of Interactive Proof Systems.

What are privacy coins?
ForkLog 13 19.11.2018

What are privacy coins?

1 What are privacy coins? Privacy-focused cryptocurrencies are peer-to-peer payment systems with their own unit of account, designed to ensure full confidentiality of financial operations through cryptographic protocols that make auditing network data difficult or impossible. Among the largest by market capitalisation are Monero, Dash and ZCash. 2 What is Monero? Monero is a peer-to-peer payment system based on the CryptoNote protocol that provides anonymity via ring signatures and stealth addresses. The protocol was created by Nicolas van Saberhagen and first implemented in Bytecoin, from which Monero is a fork [April 2014].
