Proposed in [[Algorand Scaling Byzantine Agreements for Cryptocurrencies]] Transaction confirmation time of about a minute No temporary forks or divergent views Uses VRF-based consensus mechanism Committee-based consensus that is resistant to malicious manipulation or shutting down nodes No forks if malicious actor has less than 1/3 ALGO [[dynamic participation]] - users can come and go at any time They call their consensus mechanism pure proof-of-stake Two types of nodes: Relay nodes allow for highly efficient communication paths Source of potential centralization, must be approved by Algorand foundation and is the source of the high throughput Participation nodes propose and vote on blocks Requires 2/3 voting power for liveness committee-scale consensus algo is quorum-based Byzantine agreement [[Avalanche]] performs much better in both throughput and latency since Algorand uses a VERF to elect committees and maintains a fully ordered log while Avalanche establishes only a partial order
