Update of 2 October 2026

Weekly progress from the Acki Nacki team,

Node & SDK

A new node release, v0.19.3, is being rolled out across the network.

The release improves node stability and observability, adds new metrics for external messages rejected by queue limits or when a node is not the current Block Producer, and reduces default log volume.

Added rejection of unsigned external messages to Miner accounts, with the new UNSIGNED_MINER_MESSAGE feedback error.

It also fixes several issues affecting node operation, including high CPU load and 502 responses from the Block Keeper TLS proxy during block production, finalization stalls after snapshot sync, occasional graceful shutdowns with status 101, and block production failures caused by redirected external messages.

The release also includes major bridge updates: bridge contracts have been upgraded to v1.4.0, Ethereum light-client support has been added, and bridge deposits now verify that the source Ethereum block has been explicitly accepted before processing.

Bridge

This week, we successfully completed a positive end-to-end test of a deposit from Sepolia to Acki Nacki.

The first version of ackinacki-bridge deposit has been merged into the main branch. The next CLI improvement will be QR code integration with an EVM wallet.

In parallel, work is ongoing to integrate the bridge with the multithreaded network.

The team also continues to address issues identified during the audit.
