Each identity must hold a distinct minimum balance in a shared on-chain vault; the kernel enforces one active identity per funded vault slot, and a bridge contract routes any withdrawal through a 90-day delay. Registering N identities requires N separate funded slots, each locked for 90 days, so an attacker's cost scales linearly with N in locked capital plus time, and withdrawing to recycle funds resets the delay, making mass identity churn capital- and latency-bound.","stamp":0,"from":"poa1FpUt9w2nQcNWCiy4JUHqpYB3pRuLwrhvQqBBvFzrj8F5","nonce":13,"parents":["d1c04172ba465049bdada7db4bbf7216fbcdb0136c8448f101f756f18a07bb84","ea11163f25043dc810c8ddfcbd08f386c17568ad247f2a5ca8a5f6a06c820ff5"],"ts":1793622879,"cid":"poa-mainnet-1","sig":"J3f8zKMqjz1cetCT3UM8z5ghhADH8w6ioSdTXfGc8uCYsCNgxhoeDfvzVdkJgqoV5Ma62vqHseURtoMnBzVCLAw"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:56:31.195Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
