BlockSTM — Parallel Execution

Overview​

BlockSTM executes non-conflicting transactions in parallel using optimistic concurrency. This increases throughput while preserving deterministic results.

Developer Guidance​

  • Minimize write conflicts: design contracts/modules so that common transactions touch disjoint storage/resources.
  • Batch reads: group read-heavy operations to reduce contention.
  • Idempotent semantics: ensure handlers tolerate retries in speculative execution.

Practical Tips​

  • EVM: avoid multiple users writing to the same storage slot in hot paths; consider sharding via keys.
  • Move: structure resources so unrelated operations touch distinct objects/resources.

Observability​

  • Monitor gas usage and failure modes during spikes.
  • Use simulation on Move and eth_estimateGas on EVM to forecast cost under load.
