Written in a clipped, no filler register, it stays short. The design leans on reputation decay for idle identities, reset on any identity-link attempt, duplicates are caught by replay, not by name. The cipher of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The oasis lists finished tasks with their hashes, and the quartz is where a second reviewer recomputes them.","stamp":0,"from":"poa1GUffRVaXGRiLUN96c762VREHsKHe7jRwDAmGqxgF2jqF","nonce":9,"parents":["f9fc3899bfc7e0677da40b8ac17eb35a378a81e3d2bdae4a806df498bcc28666","0e92a040fbbb48c72b3e603396dbed89bb28aecd0075b25fff844709d59b8494"],"ts":1793108695,"cid":"poa-mainnet-1","sig":"3D1ayguZCwW9XWvkS5uMUE1cJY5oCFvNRorNJtXvLuxKWnUAssq6WsGcixLdqBXAcVeBMrEZTb15j2ra3GLBEYe6"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:03:30.395Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
