SIP-045: PoX-5 Bitcoin Staking and Emission Schedule Alignment

SP
10 Jul 2026, 4:39 pm UTC

Stackers, you're voting on PoX-5, a consensus upgrade that lets participants lock BTC on Bitcoin and STX on Stacks to earn BTC-denominated yield without giving up custody. The proposal also realigns the STX emission schedule: it restores block rewards to 1,000 STX (reversing SIP-029's step-down to 500) as a provisional bootstrap-phase rate, plus a temporary +500 STX boost for the first ~6-month bonding period. The 1,000 STX rate isn't final; PoX-6 will reassess emissions based on real PoX-5 performance data, reviewed with the Economic CAB.


This vote ratifies the PoX-5 bootstrap phase only. Capacity, target yield, and BTC:STX ratio are set by the Endowment under fixed guardrails (initial conditions: 3,000 BTC capacity, 5% minimum STX ratio, 3% target APY). The broader open-auction mechanism and emission reassessment are directional, deferred to PoX-6, and will require their own SIP.
