BLOCKCHAIN is an open distributed ledger that records transactions in blocks that are secured cryptographically. This is the underlying technology of Bitcoin.
This digital decentralized ledger records transactions permanently, meaning they cannot be changed in future. BLOCKCHAINS keep growing as new transactions are added to the network.
A BLOCKCHAIN is operated by a peer-to-peer network of computers or individuals who adhere to a protocol and validate each transaction that takes place on the network.
The entire transaction, from beginning to end, is accessible to everyone on the blockchain network.
BLOCKCHAINS are broadly divided into permissioned and permissionless. They are also classified into public, private and consortium. Popular ones such as Bitcoin and Ethereum are public blockchains.
The technology is being deployed for a wide variety of uses beyond cryptocurrencies.
