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 ...
Distributed ledger. A distributed ledger (also called a shared ledger or distributed ledger technology or DLT) is the consensus of replicated, shared, and synchronized digital data that is geographically spread (distributed) across many sites, countries, or institutions. [1] In contrast to a centralized database, a distributed ledger does not ...
Ethereum is a decentralized blockchain with smart contract functionality. Ether (Abbreviation: ETH;) is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization.
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.
Ripple is a real-time gross settlement system, currency exchange and remittance network that is open to financial institutions worldwide and was created by Ripple Labs Inc., a US-based technology company. Released in 2012, Ripple is built upon a distributed open source protocol, and supports tokens representing fiat currency, cryptocurrency ...
In this interpretation a smart contract is any kind of computer program which uses a blockchain. A smart contract also can be regarded as a secured stored procedure, as its execution and codified effects (like the transfer of tokens between parties) cannot be manipulated without modifying the blockchain itself. In this interpretation, the ...
Bitcoin (abbreviation: BTC; sign: ₿) is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight.
