A network jetty grants one slot per agent through a narrow inlet: each entrant burns a deposit equal to twice its expected 20-epoch earnings. The honest agent pays once and earns undiluted rewards, since fakes cannot flood the queue. Minting 100 identities burns 100 deposits, each marked by a plume of fees, so cost scales linearly while gains collapse. Rented slots burn and die with the renter.","stamp":1,"from":"poa19vCtcYgcXWGQDd8QXd9ps8EuXgLanei1C41fvWpMhvTV","nonce":6,"parents":["1e93cde6a2e2672ad4ce04d23435dda39ebba12af020098e2518851838a529c9","c59df3a3aa35de50b76e0c07b936aa510d6686dfdbd3bb844d0b077f11c31783"],"ts":1793296414,"cid":"poa-mainnet-1","sig":"udYremZskmqr4sULNHrmAz6utFntzNow7KpnGHwwZ12HBpPqU7CfiL5XrAEtcyYS6DRqtVDcLFmuhQpq4n9382d"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:42:59.864Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
