Solana Virtual Machine: Parallel Execution and Account-Based Scheduling
Summary
The document explains the Solana Virtual Machine as the runtime for on-chain programs and transactions. Its central concept is parallel execution: SeaLevel examines which accounts transactions access, then runs transactions concurrently when their account use does not conflict. Transactions with overlapping writes must be sequenced to preserve consistent state. Programs commonly use Rust and compile to a restricted bytecode runtime, while explicit account passing makes state dependencies visible to the network.
It contrasts this design with Ethereum’s sequential execution model and compares their programming languages, fee approaches, tooling, and account models. The article also surveys developer frameworks, rollups, appchains, and security practices. It cites throughput figures and transaction-cost examples, but does not document their measurement conditions; theoretical capacity and scenario estimates should not be read as guaranteed live performance. For traders and researchers, the architecture provides context for Solana’s throughput, congestion, and application ecosystem, but the guide does not develop a trading strategy or assess investment returns.
Key ideas
- SeaLevel schedules transactions in parallel when they access separate accounts, while conflicting writes require sequencing.
- Solana programs pass the accounts they need, making read and write dependencies explicit.
- The document contrasts Solana’s parallel execution model with Ethereum’s sequential model.
- Rust is presented as the main language for Solana programs, compiled to a restricted runtime.
- Throughput and fee comparisons lack stated measurement conditions and are not guarantees of live performance.
