A tamper-proof, shared digital append-only ledger that records transactions grouped into blocks in a decentralized peer-to-peer network. The permanent recording of transactions in the Blockchain stores permanently the history of asset exchanges that take place between the peers.
Updating the ledger (usually) requires solving Byzantine Agreements (hash) with economically incentivized participation, secured by cryptography
1. New TX is broadcasted to the network
2. Each node collects TXs into blocks
3. In each round a random node is selected to generate a block
4. Other nodes accept the block if it follows the rules (valid signatures and TXs)
5. Acceptation of the block is expressed by including its hash into input data of the next block
