Acki Nacki News
Update - 02.10.26

This update brings together the main Acki Nacki progress from the week: Node & SDK and Bridge.

⚙️ 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.

Thanks to everyone in the community for following along.
