What TSUNAGI is, how it works, and how to run it
TSUNAGI is an independent, block-producing Cardano node written in Zig — proven with canonical blocks on the Preview network and now supervised for autonomous operation. Everything below is the real, current documentation.
Why an independent Cardano implementation matters — infrastructure monoculture and the case for diversity. Built without grants or treasury funding.
The technical design of the node: forge path, propagation, and consensus participation.
The five guardian subsystems — KAGAMI, YAMORI, TATE, MUSUBI, KINTSUGI — and the full slot-to-canonical pipeline, with diagrams.
The supervision layer: panic capture, evidence, restart, crash-loop breaker, rollback recommendation. Makes the node operable by humans.
The failure-memory system — every incident that ever cost a block, with root cause, fix, and lesson. The cracks repaired in gold.
Day-to-day: status, daily summary, guardianctl, rollback, KES monitoring, recovery procedures.
