Recalculate a draw yourself
Five readings are enough. They use public data only: the height committed before the draw, the Bitcoin block hash, the ticket list. Each reading gives the exact call, its arguments to copy, the value the site obtained, and the Read Contract page where you can redo it without the site.

Attestors · threshold of
Three attestors, threshold two: two matching attestations finalize a hash, one alone decides nothing. At the pilot, all three are operated by the builder, on a single machine, with the keeper. Anyone can check a reported hash against Bitcoin, and a diverging attestation leaves a public trace, the Mismatch event.
Immutable contracts, no upgrade possible. One privileged power only: raising the deposit cap, never lowering it, after a h timelock; it touches neither deposits, nor pots, nor draws. Attestors can only report a Bitcoin hash, never rewrite a finalized height.
