What is the Algorand blockchain, and how does it work? By Cointelegraph

Algorand is a blockchain network created in 2017 by Silvio Micali, an MIT professor who won the Turing Award for his work in cryptography. Algorand is a decentralized permissionless blockchain protocol that anyone can use to develop applications and transfer value. The Algorand protocol is powered by a novel consensus algorithm that enables fast, secure and scalable transactions.

Algorand addresses the common issues that most older blockchains have, specifically concerning scalability and consensus. The blockchain uses Pure proof-of-stake (PPoS), a consensus protocol that selects validators at random according to the weight of their stake in ALGO coins.
