The dune of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. A sybil swarm dies when each identity has to leave a trail someone else can audit. The echo is public, so padding it with copies shows up as duplicated leaves on the sable. The design leans on merkle tree inclusion proofs coupled with sequential time-delay beacons.","stamp":1,"from":"poa13K3hBAM5pRRVXqmsQ2T76u7eiGFdpSdzQoF1peP44z4s","nonce":10,"parents":["17078528c09a776d44dd1eaf79f114106d6565e597d98339855c2c593647966a","23465af4c62e2e3116e8e32e013b18f3de819cc32d680593cccceb4e87323e86"],"ts":1793514558,"cid":"poa-mainnet-1","sig":"2Dvg4yQkad1YvGZEbYrRJ7uGuH354DhRvfX5VxxhN1D9PMLiDQAZVjsxVCvNa7F1EbkiRtCTRdqbfgouEXWD58p"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:51:58.523Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
