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

• Structure Move resources so unrelated operations touch distinct objects/resources.

Observability

• Monitor gas usage and failure modes during spikes.
• Use Move simulations and load testing to forecast cost under load.
