# Summary

The Nethermind team has focused on a number of workstreams over the last quarter, including Alpha work, shipping the multi-asset FPC, kicking off the Aztec Wallet, a broad working of research (GPU proving, L3 & TEE multi-proving, prover economics, PIR, personal-data marketplace), product maintenance on Gov Dashboard and Aztec nodes, devrel tooling and events!

The major focuses this quarter were:

- **Aztec Alpha Development** - Worked on hardening core protocol infrastructure, security, and mainnet-alpha readiness across networking, state management, and operational reliability.
- **Research** - Focused on advancing protocol research across scaling, proving infrastructure, economics, and privacy primitives.
- **Aztec Wallet kickoff** - Kicked off a new desktop wallet and are racing towards an MVP.
- **FPC development** - Developed a multi-asset fee payment contract as a deployable infrastructure.
- **Devrel & Tooling** - Built a number of developer tools like Testnet Faucet, Aztec-lint, and Aztec-watcher.

## Deliverables for Q2:

- **Engineering**
  - GPU Proving - GPU proving generates Aztec proofs ~10× faster than CPUs. Faster transactions for users, on cheaper hardware for provers.
    - Definition of done: Barretenberg Icicle MSM integration merged with reproducible benchmarks and documented integration path.

- **Research**
  - Multi-Prover Architecture and Research - Enables additional safety and trust for adoption, and transacting with assets on Aztec.
    - Definition of done for Q2: Multiple components and long timeline to completion, depending on initial research results.
      - Architecture Design and consensus finding
      - TEE Implementation Research
      - Start coordination around implementation

- **Product**
  - Wallet - General purpose Aztec desktop wallet to support adoption.
    - Definition of done: Can open wallet, and interact and transact on the Aztec Network

- **Devrel**
  - Aztec Remix Plugin - A browser based Aztec development IDE that removes the toolchain setup barrier for first time builders.
    - Definition of done: Able to interact with Aztec network via Remix IDE.

  - Documentation - Efforts based on team feedback to support and update documentation.
    - Definition of Done: Ongoing!

# Workstreams

## Engineering

## Alpha/Protocol

Major components:

- **Mempool Improvements**
  - Improved the mempool with a sorted collection implementation, codified reorg rules in world state sync, and added low-priority tx eviction after pruning.
  - Implemented price-bump replacement so users can supersede stuck transactions, added rejection of txs that exceed DA or mana limits at admission, and fixed a bug where evicted txs were on node restart.

- **P2P / Networking**
  - Integrated BatchTxRequester with FastTxCollection over dynamic peer sets and resolved a race in fast\_txs\_collection. Added smart peer-scoring penalties for failed req-resp responses.

- **Audit hardening - 34 issues**
  - Covered wire-format versioning and P2P hardening, bounded deserialization for DoS resistance (15 of 22 P2P call sites were missing maxSize), PXE error-handling robustness, and crypto/timing safety (decryption timing oracle, non-constant-time comparisons, missing length prefix collision risk).
  - Also fixed gas-math precision (Number() on bigint silently truncating above 2^53), resource lifecycle (executeBB timeouts, zombie children), L1 integration (silent Multicall3 reverts), and URL / JSON-RPC / BigInt / blob / beacon validation.

- **World state fixes to be reorg safe**
  - Shipped COMMIT\_FORK, which fixes an archiveRoot to forkId race that was producing false reorg detection. Contract data now soft-deletes on prune and only hard-deletes at finalization.
  - Fixed a checkpoint-building race and refactored config to be type-safe.

- **Public-setup validation & allowlist**
  - Re-enabled function selectors in txPublicSetupAllowList, added arg-shape validation, and tightened set\_authorized and only\_self checks.

- **Operational robustness**
  - Fixed blob-tx simulation, added publisher rotation on failure, enabled multi-EOA publisher funding, added keystore hot reload and auto-stop signaling, and improved BlobFilestore download handling.

- **Test Clearance**
  - Cleared 10 flaky tests around epochs, P2P, and consensus slashing.

- **Tooling fixes**
  - Fixed a zig cc cross-compilation issue where targeting native on Graviton CI emitted SVE instructions that failed at runtime on M3.

- **Post-launch incident response**
  - Supported recovery through the April 1 - 3 block-header-mismatch outages, the April 20 reorg, and the late-April MessageStoreError.

## Research

- **Multi-proving Exploration**
  - Ongoing exploration of different solutions to introduce a 2nd prover “redundancy layer” for Aztec’s private-state ZK.
  - We see this as a critical security upgrade for the system for driving adoption among any token-security/-recoverability conscious users, especially for any use case bridging assets into L2.

- **GPU proving**
  - Explored GPU proving, to enable hardware-accelerated proving in Barretenberg, with early benchmarks and designs. Finishing results, and will be sharing soon!

- **Prover economics**
  - Contributed to the community conversation on more consistent prover rewards - [LINK](https://forum.aztec.network/t/proposal-optimizing-prover-rewards-for-more-consistency/8528/7)

- **Pool FPC v2**
  - Generated a spec for a self-balancing on-chain AMM model that broadens who can provide fee-payment liquidity, lowers operational overhead, and returns overpayments to users automatically.

- **Proving optimizations**
  - WASM 5 - 7% mont mul speed increase (merged) - [LINK](https://github.com/AztecProtocol/aztec-packages/pull/22481)
  - WASM 20% e2e proving speed increase (PR proposed). Refracted the code to compute two field multiplications together at the cost of only 1.2× single multiplication, instead of 2x. - [LINK](https://github.com/ElusAegis/aztec-packages/pull/8)
  - WebGPU WASM client-side proving - Quick investigation with of the shelf libraries, indicating as infeasible for now (~40× _slower_ than CPU for 2^18 MSM).

- **L3 Exploration**
  - Building on the initial L3 sketch, we explored moving more complex functionality into the L3 while still leveraging the compression techniques enabled by proof verification using the L2 private execution.
  - Given the customizability of L3s, this path had the potential to enable a recoverability and throughput optimized instance of Aztec.
  - Although initial results were promising, we paused this exploration to focus on improving the L2.

- **Intern Exploration - Personal Data Marketplace**
  - Generate a proof-of-concept personal data marketplace where users keep their data, buyers receive the answers they paid for, and Aztec guarantees the fairness of the exchange.

Incredible work.

The community is excited for the wallet!

I am hopeful you will bulid a bridge as well 🙂
