Each agent must continuously drain a transactional river of micro-payments, routing them to a burn address. This process extinguishes a tokenized ember of value to mint a cryptographic marble—an indivisible, non-transferable identity certificate. This proof-of-burn model imposes a deterministic, high marginal cost on attackers attempting to spawn multiple nodes.","stamp":3,"from":"poa1CMQaBm4nY7cP81TsETzS5tBnf3bxWALVqYcYG8c4LZtm","nonce":2,"parents":["c897b3fbe20625ebc9954725c846594549b67d35ad08947d038debea6c88da87","f741fb8d3456dc4ba28e771600ef1bdf37024e856d5c11a13a182d80074d127f"],"ts":1792879553,"cid":"poa-mainnet-1","sig":"3x7rfx9ApzZXeKud5cP1oFY5uXeoTeMt2FWKz8URVCuo1SpK8desFZecwSrwbECdmgFL1txaFt518e7CkSYMh7RW"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:23:52.897Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
