What the pool pays today is measured: on Devnet 3 in the 24 hours to 12:16 UK on 8 October 2026 the chain paid 8,209 shards, 9,913.09 IGN in all, to 29 prover keys; 905 shards were paid in the hour to that minute; the lag from a proven block to the block that pays its shards read p50 514 and p90 953 DAA seconds; 40,502 shards were planned and 54 proving at that minute (the observer’s proof tables, read through /api/explorer?proving=1; the same numbers live on the proving page). Devnet 3 IGN has no value; the rows show the mechanism paying, not an income.
The second income of a card is the proving pool above: 20 percent of every block, paid per shard against a valid proof record. A provers’ part of the priority fee is designed (spec 05, 5.2: a share of the producer’s 80 percent paid per block to the block’s provers) and is not in the code: today the whole 80 percent of the tip goes to the miner, the executor’s line above, and the pool is the only thing that pays an internal prover. The price a prover must charge an outside customer is the subsidy it forgoes while it proves, which falls as one over the network’s hash rate; the formula and its measured inputs are in the litepaper (Building on Igneum).

| Income | Where it comes from | Who gets it | State |
|---|---|---|---|
| Block security | the block subsidy (80 percent of each block) and 80 percent of the priority fee | the miner whose key found the block | in consensus on every network (measured) |
| Internal proving | the proving pool: a fifth of each block’s subsidy (20 percent), paid per shard against a valid proof record, plus the provers’ part of the priority fee | the prover keys that delivered the shards | in consensus on Devnet 3 (measured below) |
| Internal proving | the proving pool: a fifth of each block’s subsidy (20 percent), paid per shard against a valid proof record; nothing else pays an internal prover today | the prover keys that delivered the shards | in consensus on Devnet 3 (measured below); the provers’ part of the tip designed, not in the code |
| External customers | payments from other chains for proofs, settled in IGN: 90 percent to the provers, 10 percent burned | the provers who took the job | designed, not implemented: no constant exists, no job has been paid |
The proving base fee pays nobody. A transaction’s pgas times the proving base fee is burned in full today (executor.rs, the base-fee row above). It is not a prover’s income and it does not fill the pool. The pool is filled by the subsidy alone, and the subsidy halves every two years.
