Blockchain is a method of recording information that makes it impossible or difficult for the system to be changed, hacked, or manipulated. A blockchain is a distributed ledger that duplicates and distributes transactions across the network of computers participating in the blockchain.
A blockchain platform is a shared digital ledger that allows users to record transactions and share information securely, tamper-resistant. A distributed network of computers maintains the register, and each transaction is verified by consensus among the network participants. 1e1e36bf2d
