Hello Optimism Collective,
We have developed Ag^τ, a proprietary, zero-FPU semantic compression engine designed to reduce L1 calldata costs and lower hardware overhead for EVM rollups.
As Optimism scales, L1 data availability remains a significant cost center. While generic statistical compressors like Zstd provide roughly a 1.5x compression ratio on EVM transactions, Ag^τ uses a deterministic topological spiral accumulator to achieve a 4.00x compression ratio on standard EVM mempool data.
Core Engineering Features
1. 4.00x L1 Calldata Compression
By utilizing EVM-specific semantic dictionaries and address-deduplication, Ag^τ allows the op-batcher to pack 4 times more transactions into every L1 Ethereum block compared to current Zstd implementations. This directly reduces L1 footprint and lowers end-user gas fees.
2. Zero-Copy Semantic Peeking (O(1) Data Access)
With Zstd, an RPC node or sequencer must decompress an entire block into heap memory just to extract a single transaction. Ag^τ implements a 1-byte semantic header system. This allows the op-node to perform zero-copy peeking: instantly parsing transaction metadata and extracting specific witnesses in O(1) time, without invoking the decompressor or allocating heap RAM.
3. 33,000,000+ tx/s Pure L1/L2 Cache Throughput
Ag^τ requires zero heap allocations per-transaction, avoiding memory bus bottlenecks completely. In our bare-metal benchmarks, a single CPU core processes ~1.4M tx/s. When pinned across a standard 24-core Linux server, the engine scales linearly, achieving over 33.6M tx/s aggregate throughput (~36 nanoseconds per transaction).
4. Cross-Platform Determinism
Rollup consensus requires strict determinism. Ag^τ is strictly Zero-FPU, utilizing custom Q32.32 fixed-point arithmetic for its internal state. The entire verifier is #![no_std] ready and cross-compiles to WebAssembly, ensuring exact consensus matching between L1 smart contracts and L2 nodes.
Proposal for Optimism
We are seeking a Builder Grant to fund the integration of the Ag^τ decompressor into the Optimism OP Stack (op-node / op-batcher). We believe this infrastructure upgrade will significantly improve the Superchain’s DA cost efficiency.
Private Evaluation Kit
The core compression algorithms and semantic dictionary structures are our proprietary IP. However, we have prepared a closed-source Evaluation Kit (ag-tau-eval-kit) — a compiled Linux x86_64 binary with a built-in benchmarking script.
If any core contributor, OP Labs engineer, or delegate wants to validate our 4.00x ratio and throughput on their own hardware, please reach out via direct message or reply to this thread. We will provide private GitHub access to the Evaluation Kit repository under NDA.
We look forward to your feedback.
