Algorand is a Decentralised network designed to solve the blockchain trilemma of achieving speed, security, and decentralisation simultaneously without compromises. Founded by cryptography pioneer Silvio Micali in 2017, it utilises a pure proof-of-stake (PPoS) consensus mechanism that randomly and secretly selects validators to uphold the network's integrity. This allows for high throughput and instant finality while minimising energy consumption compared to proof-of-work systems. Its novel Byzantine agreement protocol ensures that the network can function effectively even in the presence of malicious actors, making it a robust platform for various applications.
