How Solana Works
Solana uses a unique consensus mechanism called Proof of History (PoH), combined with Proof of Stake (PoS).
How Proof of History Works:
PoH provides a cryptographic timestamp that orders transactions before they’re added to the blockchain, reducing network congestion and speeding up validation.
Additional Technologies:
Turbine: A block propagation protocol
Sealevel: Parallel transaction execution
Gulf Stream: Mempool-less transaction forwarding
Pipelining: Transaction processing optimization
Cloudbreak: Horizontally scaled accounts database
