Stacks has published its fourth-quarter priorities, a plan centered on bringing more Bitcoin into its ecosystem and delivering its next network upgrade.

The Bitcoin layer 2 protocol said the quarter's agenda focuses on three fronts: growing BTC bonds, putting that Bitcoin to work in ecosystem applications, and shipping the Epoch 4.1 network upgrade in early December. The priorities were released alongside Stacks' Q3 Ecosystem Report, published on October 15, 2026. Layer 2 designs of this kind exist to extend Bitcoin with capabilities the base chain does not natively offer — smart contracts among them.

Monthly Bonding Windows and a December Upgrade

Stacks plans to run Bitcoin Staking bonding periods on a monthly schedule, a cadence that gives holders recurring windows to commit BTC. The first of these windows, Bond 3, is slated to open around November 10, 2026.

Bitcoin Staking has attracted 735 BTC in total across its first two phases. Of that amount, 250 BTC came from the inaugural Genesis Bond, while Period 2 accounted for 505 BTC.

The other major Q4 item is Epoch 4.1, the next network upgrade, which Stacks is targeting for early December. The upgrade will make Clarity 7 the default for new smart contracts on the network. Clarity is the programming language used to write Stacks smart contracts, so the default change touches anything new deployed after activation. According to Stacks, the exact activation block height will be announced 30 days ahead of time.

Staking Growth and a Leadership Change

The Q3 report also recorded a jump in STX staking. Following the PoX-5 upgrade, the amount of staked STX climbed from 392 million to 493 million, an increase of more than 25%. PoX-5 is the latest iteration of Stacks' Proof of Transfer consensus, the mechanism that connects the network to Bitcoin.

STX rose approximately 50% over the four weeks leading up to October 13, 2026, outperforming Bitcoin across that stretch. The report's research attributed the outperformance to increased institutional participation in liquid staking, a setup in which staked positions remain transferable.

The report's release coincided with a leadership change. Stacks founder Muneeb Ali transitioned to CEO of Stacks Labs as it was published. With the new role came a long-range strategic vision branded the "Satoshi Upgrades." The plan aims to expand Bitcoin's capabilities in three areas — capital markets, privacy, and post-quantum security — with a timeline running through 2030.

What It Means for Developers and BTC Holders

For developers, Epoch 4.1 is the item to mark on the calendar. With Clarity 7 set to become the default for new contracts, teams building in December and beyond will need to plan around the updated version. The 30-day notice on the activation block height gives node operators, application teams, and anyone running infrastructure a month of lead time before the switch flips.

For BTC holders, the monthly bonding windows are the on-ramp: the bitcoin committed in each period is the supply that the quarter's second priority — putting Bitcoin to work inside ecosystem applications — is meant to draw on.

Stacks is managing a new bonding cadence, a push to integrate BTC into ecosystem apps, a December upgrade, and a CEO transition, all within a single quarter. The near-term scorecard, per the report: watch Bond 3 intake around November 10, watch for the Epoch 4.1 block height announcement, and watch whether the Bitcoin flowing into Stacks begins showing up inside actual apps.
