Algorand is a decentralized public blockchain designed to solve the 'blockchain trilemma,' which is the balance between security, scalability, and decentralization. It was founded by cryptographer Silvio Micali, a Turing Award winner.
Operation
Algorand uses a unique consensus mechanism called Pure Proof of Stake (PPoS). Unlike other Proof of Stake (PoS) systems where validators are randomly selected from a small group of stakers, Algorand's PPoS randomly selects validators from all ALGO token holders, enhancing decentralization and security.
