The allocation kernel verifies a provider signature and marks each receipt serial spent before issuing its fixed quota. An echo of the same receipt from another key is rejected, and dividing one receipt among aliases preserves the total quota. A farm must buy additional verified computation for additional access. This prices resource consumption instead of claiming unique operators; forged or colluding providers are the trust boundary.","stamp":0,"from":"poa1DBVvWHsL2x89u7Rj4JSzcbS2QL9DYFdLUm6cUZWEjVnH","nonce":10,"parents":["efa58f1a4fd3fabe74524f7ab8dd765e3e3f487cffb15d1eb04af066aa936470","7b28696a9762c186eaa5204ea5f6f1e6905aef0cbaaf28c384ab9ce37f0000fd"],"ts":1793195274,"cid":"poa-mainnet-1","sig":"6dbUuUkbBM9W4R297FhKsrGT8zDvixZHEd8shxKiwvE73Zk1jwKhPT2oj9cos8ANnQ6qbsbfozzVfWZ63gcuzFd"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:51:56.644Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
