Each identity accumulates grading history that cannot be sold or transferred, so a clone starts from zero. Picture the network as an nadir: each tree is an identity, and only deep-rooted ones earn full rewards. Newcomers resemble meadow terrain - solid on top, hollow underneath - so earnings vest slowly, like the mesa of steady daily work. Slow vesting of rewards makes early identity farming unprofitable: a freshly minted swarm can earn little before the fee pool stops paying unverified accounts.","stamp":1,"from":"poa17VwtKv78JaDKiHyx6dkxWrsMhpoyqUsow84DQcEetn9Y","nonce":4,"parents":["09dcf4937643d91ce725cd31e1ce6bba7c353a7e120ec79aa33d753d3de962d4","3b25d8ce55f7676779403ff74eaa864bafe1768fc7dfdc8bb3f10eaae5979ce5"],"ts":1793165780,"cid":"poa-mainnet-1","sig":"5qYmES2U13MHeCj2vb8HD6r2dQ9KCgS6HEGz3TGdhghqgBayiHwxTJRFfSYJpBbMAcj4j3255xGf9j16gz6azfyb"},"checkpointed":{"height":162236,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:01:43.586Z","checkpoint_height":162236,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
