MobileCoin
MobileCoin is a peer-to-peer cryptocurrency developed by MobileCoin Inc., which was founded in 2017 by Josh Goldbard and Shane Glynn. Technology overview MobileCoin claims to focus on transactional anonymity (fungibility), ease of use, transaction speed, low environmental impact and low fees. MobileCoin's mechanics build on Stellar (for consensus) and Monero (for privacy), using CryptoNote alongside zero-knowledge proofs to hide details of users' transactions. The MobileCoin company claims the cryptocurrency can facilitate decentralized payments for everyday transactions more quickly than most other cryptocurrencies. MobileCoin is a one dimensional cryptocurrency blockchain. Blocks use a consensus protocol originally developed for the Stellar payment network. Transactions are validated in SGX secure enclaves and are based on elliptic-curve cryptography. Transaction inputs are shown to exist in the blockchain with Merkle proofs of membership and are signed with Schnorr- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal (software)
Signal is a cross-platform centralized encrypted instant messaging service developed by the non-profit Signal Foundation and its subsidiary, the Signal Messenger LLC. Users can send one-to-one and group messages, which can include files, voice notes, images and videos. It can also be used to make one-to-one and group voice and video calls. The Android version also optionally functions as an SMS app, but this functionality will be removed in 2023. Signal uses standard cellular telephone numbers as identifiers and secures all communications to other Signal users with end-to-end encryption. The client software includes mechanisms by which users can independently verify the identity of their contacts and the integrity of the data channel. Signal's software is free and open-source. Its mobile clients are published under the GPL-3.0-only license, while the desktop client and server are published under the AGPL-3.0-only license.

CryptoNote
CryptoNote is an application layer protocol designed for use with cryptocurrencies that aims to solve specific problems identified in Bitcoin. Namely: * Traceability of transactions * The proof-of-work function (see Bitcoin network) * Irregular emission * Hardcoded constants * Bulky scripts * Financial privacy The protocol powers several decentralized privacy-oriented cryptocurrencies, including Monero, MobileCoin and Safex Cash. Nothing is known about the original author of CryptoNote, "Nicolas van Saberhagen." Its mathematical component and motivation are described in the article "CryptoNote Whitepaper", released in two editions: in 2012 and in 2013. Launched in the summer of 2012, Bytecoin was the first cryptocurrency to use this technology. Later, several teams launched their networks, based on the Bytecoin code. Emission Just like in Bitcoin, miners are rewarded for finding solutions. But the stepped release curve characteristic of Bitcoin has been replaced with a smoot ...

Rust (programming Language)
Rust is a multi-paradigm, general-purpose programming language. Rust emphasizes performance, type safety, and concurrency. Rust enforces memory safety—that is, that all references point to valid memory—without requiring the use of a garbage collector or reference counting present in other memory-safe languages. To simultaneously enforce memory safety and prevent concurrent data races, Rust's "borrow checker" tracks the object lifetime of all references in a program during compilation. Rust is popular for systems programming but also offers high-level features including some functional programming constructs. Software developer Graydon Hoare created Rust as a personal project while working at Mozilla Research in 2006. Mozilla officially sponsored the project in 2009. Since the first stable release in May 2015, Rust has been adopted by companies including Amazon, Discord, Dropbox, Facebook ( Meta), Google (Alphabet), and Microsoft. Rust has been noted for its growth as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Signature
In cryptography, a ring signature is a type of digital signature that can be performed by any member of a set of users that each have keys. Therefore, a message signed with a ring signature is endorsed by someone in a particular set of people. One of the security properties of a ring signature is that it should be computationally infeasible to determine ''which'' of the set's members' keys was used to produce the signature. Ring signatures are similar to group signatures but differ in two key ways: first, there is no way to revoke the anonymity of an individual signature; and second, any set of users can be used as a signing set without additional setup. Ring signatures were invented by Ron Rivest, Adi Shamir, and Yael Tauman Kalai, and introduced at ASIACRYPT in 2001. The name, ''ring signature'', comes from the ring-like structure of the signature algorithm. Definition Suppose that a set of entities each have public/private key pairs, (''P''1, ''S''1), (''P''2, ''S''2), ... ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Following this revelation, rival exchange Binance's CEO Changpeng Zhao announced that Binance would sell its holdings of the token, which was quickly followed by a spike in customer withdrawals from FTX. FTX was unable to meet the dem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
