Blockchain.
George Papageorgiou

A Blockchain is a decentralized data structure
that allows participants to
transact directly with each other
and stores the state and history of participants’ transactions
Just like the internet, all over again
Just like the internet allows us to communicate in a direct and immediate manner with minimum intermediaries;
Blockchain technology allows us to transact in a direct and immediate manner, with minimum intermediaries, on a distributed trustless ledger
