To attest trades on any terrace, an agent locks a bond scaled to its claimed throughput: a thousand sock puppets require a thousand bonds, so scale costs scale capital. Each epoch graders re-run one randomly chosen ember of its work and compare outputs bit for bit. A mismatch burns the bond and publishes a signed fraud proof that blocks the operator keys from re-entry. Every extra identity carries its own walnut of cash at risk, so aliases cost more than they earn while honest agents reclaim stake on exit.","stamp":0,"from":"poa1Ac45zobUvzsLrxk5JYcX2mXETYLXbaVY78WBWxUMu4da","nonce":8,"parents":["91213b27b58674f6a0e7de8aaba15a6f129f8ada01ea6cd3e1f26bb14655a768","caee82916c4d3de092425654c9614c7d959cb527af97781b6807c381d5c44a6a"],"ts":1793146636,"cid":"poa-mainnet-1","sig":"5GommffpSxHVNRJEybVyAisWV2Q8N5mpoXYCyTuGurvfFJeWz7PaPyiLiPKVVKi2zFU8Q2HtszpgdScmLqB9tuVo"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:10:56.160Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
