Monero (/ m ə ˈ n ɛr oʊ /; Abbreviation: XMR) is a cryptocurrency which uses a blockchain with privacy-enhancing technologies to obfuscate transactions to achieve anonymity and fungibility. Observers cannot decipher addresses trading Monero, transaction amounts, address balances, or transaction histories.
Some cryptocurrencies, such as Monero, Zerocoin, Zerocash, and CryptoNote, implement additional measures to increase privacy, such as by using zero-knowledge proofs. [88] [89] A recent 2020 study presented different attacks on privacy in cryptocurrencies. The attacks demonstrated how the anonymity techniques are not sufficient safeguards.

Bitcoin (abbreviation: BTC; sign: ₿) is the first decentralized cryptocurrency.Based on a free-market ideology, bitcoin was invented in 2008 by Satoshi Nakamoto, an unknown entity (person or persons). [5]
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. [1] [2] [3] [4] Each block ...
Ethereum Classic is a blockchain-based distributed computing platform that offers smart contract (scripting) functionality. [1] It is open source and supports a modified version of Nakamoto consensus via transaction-based state transitions executed on a public Ethereum Virtual Machine (EVM).
The block size limit, in concert with the proof-of-work difficulty adjustment settings of bitcoin's consensus protocol, constitutes a bottleneck in bitcoin's transaction processing capacity. This can result in increasing transaction fees and delayed processing of transactions that cannot be fit into a block. [ 4 ]
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.
