Solana SOL

Project profile

Solana is a public, programmable blockchain designed for high-throughput transaction processing and a shared execution environment for applications. Its uses include payments, stablecoin transfers, decentralized finance (DeFi), trading and other digital assets. Solana refers to the network and its infrastructure; SOL is its native cryptocurrency. Applications can use the same underlying ledger while implementing their own rules, assets and services. On Solana, smart contracts are called programs. Transactions contain instructions that invoke programs and read or update accounts holding balances and other data. Validators process transactions, verify signatures and execute program instructions to check the resulting state changes. They also produce blocks and vote on which blocks the network accepts. This combines application execution with agreement on a shared ledger; actual processing capacity and transaction experience depend on network conditions, competing demand and the resources required by each transaction. Solana uses proof-of-stake (PoS), with consensus votes weighted by the SOL stake associated with each validator. Proof of History (PoH) serves a different role: it uses a sequential computation to create a verifiable record of elapsed time and event ordering. This helps coordinate transaction processing. The two work together: validators execute and check transactions and use stake-weighted voting to establish consensus, while PoH supplies the timing and ordering framework for coordination. SOL pays network transaction fees, which include a base fee and an optional prioritization fee. A prioritization fee can improve scheduling priority. SOL can also be staked by delegating it to validators, adding to their consensus voting weight. Holders retain ownership of their SOL during native delegation. Staking rewards are calculated for eligible delegated stake, while activation, deactivation and subsequent withdrawal follow protocol timing rules. Other assets issued on Solana generally use token programs and are commonly described as SPL tokens. Each asset has its own mint, supply and relevant authorities or application rules. Stablecoins and application tokens are distinct assets from SOL and use the same network to process transactions. Their issuance, redemption arrangements and economic roles follow their own asset and application designs. SOL supply changes through inflationary issuance and protocol fee-burning rules. Under the documented fee structure, part of the base transaction fee is burned, while prioritization fees go to validators. Supply changes reflect issuance and burning together. Native staking rewards are funded by newly issued SOL under the inflation mechanism. Staking rewards vary with protocol parameters, total active stake, validator performance and commission.
