Rewards

Verified against: Core v2.0.2 reward and Coinbase validation, Qwertycoin mainnet, 2026-09-29.

When a qualified payee exists, 10% of the scheduled subsidy—not transaction fees—is allocated to service:

service = floor(scheduled_subsidy * 1000 / 10000)
miner   = scheduled_subsidy - service + transaction_fees

Example: if scheduled subsidy is 34,400,000,000 atomic units (344 QWC) and fees are 12,345 atomic units, service receives 3,440,000,000 atomic units (34.4 QWC) and the miner receives 30,960,012,345. Integer division floors the service amount; all arithmetic is checked.

A block in payout epoch E uses only the closed qualified set from service epoch E-1. Selection is deterministic and rotates over the canonically ordered set. Epoch 0 has no service reward; epoch 1 is the first service epoch; height 1440 (start of epoch 2) is the first possible payout. This does not promise any newly started node a reward at a fixed wall-clock time.

If the closed source set is legitimately empty, mainnet's compiled miner_fallback gives the entire subsidy and fees to the miner; no service node is paid. Missing/corrupt consensus state is not an empty set and fails closed.

Service outputs are normal wallet-detectable one-time outputs and obey Coinbase maturity. get_service_rewards previews a height using the correct source epoch; get_epose_block_reward verifies a canonical historical block. Never infer attribution solely from output position or current-epoch flags.
