Neptune & Triton Development Update

Date: February 16, 2026

1. Last Week by the Numbers

neptune-core

  • Issues: 6 raised, 5 closed
  • Pull Requests: 2 merged
  • Commits: 14 merged into master

triton-vm

  • Pull Requests: 2 merged
  • Commits: 10 merged into master

2. Stand-up Summary

Alan Szepieniec

  • Last Week: Completed the STIR PR review and released Neptune Core version 0.6.1. Identified and fixed a bug related to UTXO consolidation. Reviewed Proof of Reserves and Proof of Payment PRs.
  • Coming Week: Focusing on refining the Zero-Knowledge (ZK) proof logic and addressing the service gap left by the VXB wallet discontinuation.

Thorkil Værge

  • Last Week: On holiday.
  • Coming Week: Prioritizing wallet-related speed optimizations. Investigating the removal or optionality of application-level membership management code. Taking over hosting for the explorer previously managed by VXB.

Ferdinand Sauer

  • Last Week: Finished and merged the STIR PR, enabling user selection between STIR and FRI protocols. Completed the WASM PR, ensuring Triton VM compatibility with WASM 32.
  • Coming Week: Review Alan’s notes on ZK to address the current proof-of-ZK. Depending on where things go: start to implement “Giacomo’s trick” to enhance verifier speed or update the TASM STIR verifier.

3. Technical Discussion

STIR and FRI Integration
The merger of the STIR PR marks a significant milestone, allowing a choice between STIR and FRI protocols. In addition, users can now select a “proximity regime” based on whether they require proven soundness results or are comfortable with conjectured results.

Zero-Knowledge (ZK) Integrity
Currently, there is no convincing proof that Triton VM is indeed zero-knowledge. (There is also no proof that it is not zero-knowledge.) The team is planning to address this by:

  • Taking randomizers for quotient table into account more explicitly.
  • Establishing a regression test for the ZK property to prevent future silent failures.
  • Prioritizing ZK fixes before proceeding with TASM updates to ensure the implementation aligns with advertised cryptographic claims.

Bug Fix
A logic in neptune-core was resolved where the total spent amount was incorrectly calculated during UTXO consolidation. This was a result of mismatch between the list of all spendable UTXOs list and the sublist of UTXOs being spent in this transaction. UTXO consolidation is an opt-in feature and the now-fixed bug could not result in a loss of funds.

4. Updates and Announcements

  • Version 0.6.1 Released: Neptune Core v0.6.1 is now live.
  • VXB Wallet Discontinuation: Regrettably, the VXB team is discontinuing their service. The core team is discussing how to address the service gap left behind.
  • WASM Compatibility: Triton VM is now fully compatible with WASM 32.
