- <<<1 Announce
- Ten minutes before the round the keeper writes a memo on Solana: the round number and a slot that has not happened yet.
- <<<2 The bit
- When that slot lands, its block hash decides each camera's bit: watch or do not watch. Nobody, the keeper included, could know it when the memo was written.
- <<<3 The answer
- Each camera answers 16 ordinary questions, then is asked for the probability that its activations were read. A second memo carries both bits, both answers and the hash of the log.
Every round is published whole: the questions, the answers and the two memos.
