Galaxy Research details the technical path for Bitcoin’s next major soft-fork as developers weigh OP_CAT and OP_CTV upgrades against a backdrop of historic institutional capital shifts.
The technical architecture of the Bitcoin network is entering a pivotal phase as developers move from theoretical debate to concrete implementation strategies for the next major soft-fork. According to a June 2026 report from Galaxy Research, the focus has shifted to two specific opcodes: OP_CAT (BIP 347) and OP_CHECKTEMPLATEVERIFY (OP_CTV, BIP 119). These proposed upgrades are designed to introduce ‘covenants,’ spending constraints that would enhance Bitcoin’s programmability and scaling without compromising its core layer-one integrity.
Advocates for these upgrades, including Taproot Wizards and StarkWare, suggest that OP_CAT could enable trustless Bitcoin Layer-2 bridges using STARK and Merkle proof-based designs. Prototypes like ‘CatVM’ are already being highlighted as leading examples of how Bitcoin could host more expressive spending conditions. However, Galaxy Research cautions that OP_CAT is a base primitive, not a complete solution for Ethereum-style smart contracts. To reach its full potential, the opcode would likely require a broader bundle of companion upgrades, such as OP_TWEAK_VERIFY, in a Taproot-style package. Projections suggest Bitcoin Core developers may reach internal consensus by 2025, with activation following one to two years later.
Despite technical optimism, the path to activation faces a high political bar. The emergence of Ordinals following the 2021 Taproot upgrade has made many stakeholders skeptical of unforeseen consequences. Governance remains complex, as miners, large exchanges, and major ETF issuers have remained largely silent on the covenant debate. This silence creates a vacuum where the ‘protocol ideation’ phase is heavily influenced by vocal advocates, while the broader economic majority has yet to weigh in on the risks of increasing L1 complexity.
On the institutional front, the Bitcoin ecosystem is navigating significant capital repositioning. U.S. spot Bitcoin ETFs recorded a $6.35 billion net outflow over a recent 30-day window, the largest withdrawal period since their January 2024 inception. While these outflows coincide with a 17% monthly price decline, data suggests the heaviest selling may have peaked, as weekly redemptions fell by nearly 87% from early June highs. Despite this bleed, the aggregate ETF complex still retains approximately $53.4 billion in net inflows, suggesting the long-term institutional base remains largely intact.
Macroeconomic forces and geopolitical instability continue to exert pressure. Tensions in the Strait of Hormuz, exacerbated by conflicting signals from Iran and the United States, have kept risk assets on edge. Bitcoin has been trading near $64,000, reflecting broader market unease. Galaxy Research notes that in a deeper market drawdown—with a potential floor in the $30,000 range—ETF redemptions could transition from a stabilizing force to a source of forced selling. This challenges the narrative of an institutional ‘floor’ and underscores the importance of protocol developments in providing the network with the technical utility needed to withstand global economic shifts.
As the protocol evolves, the network’s resilience is being tested by both internal engineering debates and external volatility. The coming year will be decisive for Bitcoin’s digital sovereignty, as the community decides whether to embrace the complexity of covenants or maintain the conservative status quo that has defined the network’s security model for over a decade. For technologists, the intersection of these protocol upgrades and institutional flows will define the next era of American digital leadership.
