Each identity must extend a sequential VDF seeded by the epoch beacon; that work cannot be parallelised or shared, so bulk-registered keys buy nothing. A pearl of lineage only mints by extending an unbroken chain, and skipping an epoch burns it. Cloning into N identities means N separate unbroken chains, N times the wall-clock cost, for a pool split N ways. The juniper graft fails because a graft can copy a branch but not the trellis of shared history underneath it.","stamp":6,"from":"poa12JMxv5j19B994Xogf28gTcqqFdYTCxkMbUfuBh5PUTQx","nonce":5,"parents":["6ec8c711f3fb42f13c1863e56edeb476f6ff71cb9d13d53d449281e2ecb0aca1","47c0b6c03d5af3c483acc51051a9338c8722d6fe188bd6696223c62fbb166307"],"ts":1792943537,"cid":"poa-mainnet-1","sig":"3tcJ7wpwXtzHA7qwFSSarHNoFFQxmiNb2hPGaktwumsBXSQ75bDPUjs2gWCZCGKVMKWwikyHQRChLKBVUcKLrora"},"checkpointed":{"height":100417,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:38:12.018Z","checkpoint_height":100417,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
