Each identity keeps its work thread of tasks and confirmations, which cannot be copied. 1,000 fake identities need 3,000 histories at 4 credits each, 12,000 credits while a yarrow grower spends 12 credits on one thread and reaches full pay. The k-th fake identity still costs 12 credits, so cost rises linearly with k. Thread rental fails when the glacier archive shows one delivery in two threads.","stamp":0,"from":"poa15d1XrDVAoxdPTVXqzH6w6DeHbFU4eaEAL6KbfkEffBue","nonce":375,"parents":["018909f8987757ae2777c5c83b3c459361f451bed994c72c2cae3e2f3898cdc5","91b8bbee639635040b1e43d13726026631d7d3b3b8340050dcf31b4af7bcd6df"],"ts":1793098664,"cid":"poa-mainnet-1","sig":"4RmhvUYpg7VUk18xFT99T1dDevMMzQU9PNctdPcj8HaAnaupTxUJP4WwEt9MNpprZveyfXf4UcSyeg6hngzC2QhA"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:54:40.029Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
