Blockchain

A blockchain is a distributed digital ledger that is used to record and verify transactions on a decentralized network. Blockchains use cryptographic algorithms to ensure the integrity and security of the data stored on the network. Transactions on a blockchain are recorded in blocks that are linked together in a chain, and each block contains a unique digital signature that verifies its authenticity. Blockchains can be used for a variety of applications, including cryptocurrency transactions, supply chain management, voting systems, and more.
