Algorand is a public blockchain that is truly secure, scalable and decentralized. It is permissionless and works in a highly asynchronous environment. It dispenses with “proof of work” and “miners” and requires only a negligible amount of computation. Moreover, its transaction history does not “fork”, guaranteeing immediate finality of a transaction the moment the transaction enters the blockchain. In this talk I will introduce Algorand’s core technology and roadmap.
