# Stacks’ PoX-6 Could Shift Bitcoin Staking Terms to Algorithmic Settings By Simon Yoon Canonical URL: https://www.tokenpost.com/news/technology/26581 Published: 2026-10-03T16:40:49.000Z Updated: 2026-10-03T16:40:49.000Z Section: Technology > PoX-5 leaves launch parameters to the Stacks Endowment. Its ratified plan says a later phase could calculate staking terms through the protocol, without approving a final PoX-6 design. Stacks’ ratified Bitcoin-staking plan leaves launch terms to the Stacks Endowment and describes PoX-6 as a possible later shift to protocol-calculated settings, without approving a final design for the upgrade. PoX-5 activated July 30, 2026, at Bitcoin block 960,230. The system pairs a Bitcoin (BTC) timelock with an STX lock for BTC-denominated yield, while participants retain control of their BTC through their own keys. During PoX-5’s bootstrap phase, the Stacks Endowment sets program parameters. The plan lists initial conditions of 3,000 BTC in capacity, a 5% minimum STX ratio and 3% target annual percentage yield in BTC. Final values are set before activation and may vary with partner capacity. The plan describes PoX-6 as a phase that could move calculation of the yield rate, capacity and BTC-to-STX ratio to the protocol. A permissionless auction model has also been discussed as a future possibility, but the ratified plan does not establish that mechanism. The distinction affects how participants’ terms would be determined. Under the current plan, the Endowment sets launch parameters; a protocol-calculated approach could change how those parameters are set. The plan calls for a PoX-6 reassessment based on performance during the bootstrap phase, and PoX-5’s approval does not commit Stacks to a specific PoX-6 design.
