Pure proof-of-stake at scale

Algorand's pure proof-of-stake protocol randomly and secretly selects validators for each block, so the network stays fast and secure without forks. Blocks finalize in seconds with negligible fees, and Algorand runs a carbon-negative network suited to high-throughput financial applications.
