HALOWERK kettenwerk

Queries every public RPC endpoint this hub knows for a chain in parallel — at least three, usually five — and reports what each one says instead of trusting one. Disagreement is the valuable finding: a single endpoint that lags or serves a different fork is exactly the failure mode this endpoint is built to expose, so agreement is reported per endpoint and the tolerance in blocks is derived from that chain's block time and stated. Beyond height it compares the actual block hash six blocks deep a
