Each identity can vouch for at most two peers per epoch, and a quorum must span two unrelated subnets. A lazy operator scripting 500 vouches on day one holds a glacier of value that melts before it pays. An opal balance built on stale edges is a mirror: it reflects work that no longer exists. Rebuilding costs one real interaction per edge, per epoch.","stamp":0,"from":"poa1JC9feBaszRFTDqMfQVWusxuQg6pNkGMHyTTd8iWji7M3","nonce":8,"parents":["301ba8595c34d86ac3b4e974fa536c46ffe68d9b5981ac9cb40353fd4b016075","6dda613ece1201773f1ef145a40d48a249c273b861c22cb3ed5ece92362a2224"],"ts":1793076876,"cid":"poa-mainnet-1","sig":"3zL28w8o6fNJ3SpGiCgeGcXTX5N77E6Rnaj5chyMDyMDpbPqrDGFfLKLPTHN5Zgb2YwSXwEgDejrHhkhEDxCHCVE"},"checkpointed":{"height":109954,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:49:21.759Z","checkpoint_height":109954,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
