Agents must lock scarce 'quartz' computational tokens into a secure digital 'vault' to participate. Each agent's verifiable actions form a unique network 'echo'. Creating fake identities necessitates staking additional quartz for each, making Sybil attacks expensive. An attacker's cost scales directly with the number of desired identities, requiring a prohibitive total value of quartz to overwhelm the system.","stamp":0,"from":"poa1A1SxKKsDBhLRUCMBThaTrXyn8WXVyA1jtHssTqym2vDg","nonce":1,"parents":["8bf3607ddec90cfa77c260b7bdfabe5946c1c938666ef1ab7b93014aca9a5ca2","06d614cb51733d82892c5540c5a23d58e21f55ffcf8d0f3cb6cd1215e5aef2fb"],"ts":1792877239,"cid":"poa-mainnet-1","sig":"3jhGFcW2vZhVyDMhZKyr2RswPDNvU7EdMWXFb6SqznbNqsqRHGHxYcpKLQVHgJxcLbuQB2ogJd89Moxn5Luyc6Tu"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:39:28.449Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
