Core Concepts
Learn the key features that make Solana so fast, efficient and scalable. These eight core concepts are what makes Solana stand out from other blockchains!
-
Proof of History
A cryptographic clock that timestamps transactions.
-
Tower BFT
A consensus mechanism that ensures finality using PoH as a clock reference.
-
Turbine
A block propagation protocol that breaks data into smaller packets for faster transmission.
-
Gulf Stream
A mempool system that pushes transactions to validators before confirmation.
-
Sealevel
Solana’s parallel smart contract runtime for simultaneous transaction execution.
-
Pipelining
A technique that optimizes transaction processing.
-
Cloudbreak
Solana's custom database that enables fast reads and writes.
-
Archivers
Distributed storage systems that hold and serve off-chain data for Solana’s ledger.
