SIP-031 passed with over 97% of all voting power cast in favor of creating the new Stacks Endowment. As part of this network upgrade, expected at Bitcoin block 907740, total supply will increase by 500M STX over the next 5 years. Of that, there will be an additional 100M STX immediately reflected in the circulating supply, with the remainder emitting over a 5 year period. Once all unlocks complete, total supply will reach approximately 2.2 billion STX (up from ~1.7 billion today). The network’s average yearly emissions during this period will be 5.75%. After this period, emissions return to under 2% annually from PoX. Total supply remains uncapped. As covered at length in SIP-031, emissions and conversion programs were designed to remain below the median inflation rate of Top 50 crypto projects (10.18%). Excluding the initial mint, annual emissions are as follows: Year 1 (7%), Year 2 (7%), Year 3 (7%), Year 4 (4.25%), Year 5 (3.5%). The hard fork to instantiate these changes is expected on July 29, 2025. Access full voting results and next steps here: https://stacks.org/sip-031-results
