A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves).
Solidity is a programming language for implementing smart contracts [6] [7] on various blockchain platforms, most notably, Ethereum. [8] Solidity is licensed under GNU General Public License v3.0. [9] Solidity was designed by Gavin Wood [10] [non-primary source needed] and developed by Christian Reitwiessner, Alex Beregszaszi, and several ...
Algorand is a blockchain platform founded in 2017 by Silvio Micali, a computer scientist and professor at the Massachusetts Institute of Technology (MIT). Micali's expertise in cryptography and distributed systems has been instrumental in shaping Algorand's innovative approach to blockchain technology. [2] [3]
Uses Distributed computing. Cardano is a public blockchain platform. It is open-source and decentralized, with consensus achieved using proof of stake. It can facilitate peer-to-peer transactions with its internal cryptocurrency, ADA. [5] Cardano's development began in 2015, led by Ethereum co-founder Charles Hoskinson.
Vitaly Dmitrievich Buterin ( Russian: Вита́лий Дми́триевич Буте́рин ), better known as Vitalik Buterin (Russian: Вита́лик Буте́рин; born 31 January [2] 1994), is a Canadian computer programmer and co-founder of Ethereum. Buterin became involved with cryptocurrency early in its inception, co-founding ...
The blockchain-based database is a combination of traditional database and distributed database where data is transacted and recorded via Database Interface [1] (also known as Compute Interface) [2] supported by multiple-layers of blockchains. [3] The database itself is shared in the form of an encrypted /immutable ledger which makes the ...
In the blockchain, bitcoins are linked to specific addresses that are hashes of a public key. Creating an address involves generating a random private key and then computing the corresponding address. This process is almost instant, but the reverse (finding the private key for a given address) is nearly impossible.
Web3. Web3 (also known as Web 3.0 [1] [2] [3]) is an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics. [4] Some technologists and journalists have contrasted it with Web 2.0, wherein they say data and content are centralized in a small group ...
