Resolving the exact build
Model and control board, read off the machine
Four questions - family, model, board, install method - narrow 73 published builds down to the one that fits. You leave with the file name, its size and its SHA-256
Exact model, exact board, one verified route. Rollback stays armed
Nothing on this page asks for belief. The catalog, the checksums, the security contact and the machine-readable index are all public, and the two things operators care about most - the developer fee and the way back to stock - are visible inside the firmware itself, not buried in a document
The Antminer line has a history, and we have been in it the whole way: generation after generation, from the S9 era to the S21. More than a million machines worldwide have run VNISH firmware, and every one of them taught us something about that exact model
The one-miner route and the five gates
Compare SHA-256, then flash over the network
One machine reports for a day before anything else moves
Propagation continues only while the gates stay green
