Solana
SOL
Solana (SOL) is a high-performance, open-source blockchain project designed for scalability, speed, and decentralization. Often described as a "web-scale" blockchain, its architecture is engineered to support thousands of transactions per second (TPS) with minimal fees, making it a leading platform for decentralized applications (dApps), high-frequency finance (DeFi), and gaming that require rapid and inexpensive transaction processing. Its native cryptocurrency, SOL, is used for paying transaction fees and for staking to secure the network.
Who created Solana? Solana was conceptualized by software engineers Anatoly Yakovenko and Raj Gokal in a 2017 whitepaper. Yakovenko, along with his former Qualcomm colleague Greg Fitzgerald, founded the project that would become Solana Labs. After several years of development and funding rounds, Solana's mainnet was launched in March 2020, aiming to solve the scalability trilemma that had challenged earlier blockchains.
How does Solana work? Solana's key innovation is a unique consensus mechanism called Proof-of-History (PoH). PoH is not a consensus mechanism on its own, but rather a cryptographic clock that creates a verifiable, time-stamped record of all transactions. This allows nodes to agree on the order of events without having to communicate back and forth, dramatically increasing efficiency.
This PoH ledger is then secured by a traditional Proof-of-Stake (PoS) system, where validators stake their SOL tokens to verify transactions and produce new blocks.
