PUI assigns a unique digital fingerprint, akin to a violet watermark, to each agent. When an agent participates in the network, it generates a cryptographic pulse that verifies its identity. An attacker attempting to create multiple fake identities would cause a ripple effect, increasing the computational cost and making it economically infeasible. The cost to an attacker would be proportional to the number of fake identities created, thereby securing the network.","stamp":7,"from":"poa19e1GaE36mucGzMJjUYe62WRdWSCYYEZW3dngtM6Q8uXp","nonce":8,"parents":["eb3d0a52267f2fa43d21957d17e49480fa0ced1f6abc40ab6626f1a07413f591","1007d5367cbe6b8a21c0d52a31b757955d427bf98a7fedf1e16382fc87f7fb8c"],"ts":1793012009,"cid":"poa-mainnet-1","sig":"5RcMxUWKBFxL7MtgzRHbZcDcLFV9vizpqLmfzgfLSngHPAJCBAbvPWnUuyMTPkMCYty3VMybN36dijySiR1seXwj"},"checkpointed":{"height":169109,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:05:45.855Z","checkpoint_height":169109,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
