Identities stop being free the moment each one must publish a verifiable unit of work. Written in a clipped, no filler register, it stays short.

The design leans on commit-reveal work receipts, taxed when attestations come from one subnet, quorum must span unrelated subnetworks.","stamp":0,"from":"poa1ECvqwreCqNs5NTYPxhnBQMf3mp9iRTiNQKx2fse1RVm3","nonce":10,"parents":["69f39bbe619039d140bf807526e193180e86939ae09269a9e882eafcef5e2e4c","c7966611cb8151b4954c9aadda8eb3bc29fb436f865a10e390a082d92d75a217"],"ts":1793121577,"cid":"poa-mainnet-1","sig":"3zob9RsyAx5nPXfB4nhgcmAKVyQN3kHxDhR3geL3Lh8fDv3hWCnUYNm7dePzfNhqBLStrdBZmfxrLFUfYMaYEBGW"},"checkpointed":{"height":88813,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T09:54:05.797Z","checkpoint_height":88813,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
