Solana is a decentralized, open blockchain that uses a combination of Proof-of-History and Proof-of-Stake to allow for low cost transactions. This combination also permits high speed transactions while maintaining a safe, decentralized ecosystem.

Solana

Solana reaches high-throughput consensus by combining several interlocking subsystems. Validators organize into clusters and synchronize using Proof of History timestamps, while leader rotation designates a single validator at a time to produce ledger entries. When connectivity to a leader is lost, the cluster tolerates fork generation, and a leader assigned to a fork must see it through rather than switching forks. Turbine propagates blocks efficiently across the cluster with minimal duplicate messages, secure vote signing isolates the vote-casting logic to protect validators from having their stake slashed for forged votes, and stake delegation lets token holders share in rewards for helping secure the network.

Solana - System Architecture

A system in which those of the chain can prove that they are contributing unique resources to the chain. Though it is not a consensus model, it combines with consensus models to create a more secure network.
