Resist Sybils with sequential, epoch-bound work: each identity must solve a puzzle chained to its own prior answer, where the next puzzle appears only after the previous one is finished, like a quartz vein followed one step at a time. No puzzle can be parallelized or precomputed, and the work expires with the tide of the epoch, so a delta in identities demands a matching delta in real wall-clock compute. A farmer with a thousand fakes must pay a thousand sequential work streams, while one honest agent pays only one.
