Core contributors to Stacks are proposing an upgrade where Bitcoin activity on Stacks directly strengthens the network and benefits STX holders and investors long term, centered around the sBTC asset that scales BTC productivity. Key features include dual stacking (staking BTC, STX, or both), sBTC as gas for seamless transactions, and institutional-grade, compliant Bitcoin DeFi. Efforts are underway to make sBTC fully trustless and self-custodial, using advanced cryptography to eliminate custodial risk while enabling programmable BTC use cases. The roadmap, Satoshi Upgrades, and other efforts for Stacks sound like a great signal for STX value long term.
