image Canaan Avalon Nano3S -A3197S ASIC Reverse Engineering Report The first public reverse-engineering of Canaan's A3197S Bitcoin mining ASIC Date: June 5, 2026 Conducted by: Nikos ASIC: Canaan A3197S (Avalon-Nano class) — 10 SHA-256 engines per chip Host platform: Canaan Avalon Nano 3s (12× A3197S, Kendryte K230D dual-core RISC-V) Stock Firmware: Avalon Nano 3s release 2025061101 (June 2025) Test Firmware: TNA-OS (custom mining stack built on the cracked protocol) Board Revision: MM-NANO3S-V0.2 Executive Summary To the author's knowledge, this is the first time anyone has publicly reverse-engineered Canaan's A3197S Bitcoin mining ASIC — the chip at the heart of the Avalon Nano 3s and related Avalon-Nano-class hardware. The A3197S is closed silicon. Its host-to-chip mining protocol is undocumented; the second RISC-V core that drives it ships encrypted on flash; and there is no published information describing how the chip is brought up, configured, fed work, or how it reports results. Every existing deployment of this ASIC runs the vendor's closed stack and nothing else. This study cracked that wall: the complete A3197S serial mining protocol was recovered — chain enumeration, per-chip configuration and calibration, the high-speed bus bring-up, work dispatch, version-rolling (AsicBoost) setup, and the nonce-report format the chip returns. With the protocol understood, a branch of firmware (TNA-OS) was written to drive the chips directly, independently of any vendor software. FULL REPORT AVAILABLE HERE :

GM builders Yesterday we set new hashing records 10.948TH out of 4xbm1370 asics and validated that the NerdQaxe ++ rev 5.1 circuit design cannot take more than 320w . Confirmed twice. Twice failed at the same spot - same 320w. No matter volts / amp adjustment. That's it for the foreseeable future on firmware and OC testing. Think we blown up enough hardware and collected valuable insight and data.
