A blockchain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data.
Openness, accountability, and honesty define government transparency. In a free society, transparency is government's obligation to share information with citizens. It is at the heart of how citizens hold their public officials accountable.
Consensus is the brain of the blockchain. It decides which blocks to add by pitching nodes against each other in a cryptographic race for a Bitcoin prize. ... It ensures each block has gone through a complex, mathematical process before becoming an immutable part of the blockchain.
