Introducing FAFO
Fast Ahead-of-Formation Optimization (FAFO) is a high-throughput transaction scheduler that reimagines how blockchains scale. It achieves 1M+ transactions per second on a single server by reordering transactions before block formation. FAFO is a fully EVM-compatible scheduler built to test the upper bounds of execution-layer performance.

Key Innovations
Key Innovations
A /
Ahead-of-Formation Scheduling
Reorders transactions before blocksare formed for maximum concurrency. Eliminates the bottlenecks of legacy mempool-based schedulers.
C /
ParaBloom™
Cache-resident, low-overhead Bloom filters identify conflicting transactions in microseconds and group them into parallelizable frames.
B /
Conflict-Serializable Execution
Uses ParaBloom filters and DAG-based scheduling to ensure all transactions are safe to run in parallel — with no rollback or speculation.
D /
DAG-Based Runtime
Each EVM storage slot maps to a node in a dependency DAG. Transactions execute as soon as their dependencies are resolved.
