Hey, there is so much content around BlockChain and i am getting a bit confused. Could you explain the technology to me, in a sentence or two?
Well, simply put, Blockchain is a software solution (protocol) for reaching agreement (consensus) within a leaderless (decentralized) group of peers (peer to peer), that events have occurred, as they occur (synchronised) and that of these each events is recorded in an indisputable (immutable) historical list (ledger) which each peer has a copy of (distributed).
You know how in a playground football game each player knows what the score is at any one time and you can’t change the score without convincing everyone playing that there’s a very good reason for doing so? Well in a very similar way, each node in a blockchain-based peer to peer network has an identical copy of the network’s ledger of events, and that ledger is immutable.
