Bitcoin protocol upgrades OP_CAT and OP_CTV remain in the ideation phase as developers weigh security risks against the need for enhanced transaction programmability and trustless bridges.
The drive to enhance Bitcoin’s transaction programmability is meeting the reality of its conservative governance model. While the broader technology sector focuses on artificial intelligence returns and industrial robotics, the Bitcoin developer community is locked in a debate over “covenants”—spending conditions that could fundamentally change how the network handles digital assets. At the center are two leading proposals: BIP 347 (OP_CAT) and BIP 119 (OP_CTV). According to Galaxy Research, these opcodes represent the most viable path toward enabling advanced smart contract logic on Bitcoin without sacrificing security.
However, despite vocal support from application developers and media influencers like the Taproot Wizards team, the proposals have made no tangible progress toward activation as of early 2024. The bottleneck remains the Bitcoin Core maintainers, who act as the final gatekeepers for the protocol’s GitHub repository. Currently, there is no selected maintainer or agreed-upon activation method for either proposal. This cautious approach is partly a reaction to the unforeseen rise of inscriptions following the Taproot upgrade, which has made the community skeptical of introducing new opcodes that could be used for unintended purposes. Developers must now prove that any new bridge attack surfaces are fully understood before a merge can occur.
Technically, the two proposals offer different paths to increased expressivity. OP_CTV focuses on pre-computed covenants that allow a sender to impose spending conditions on a recipient. This is seen as a “narrower” path, specifically designed to avoid the risks of recursive covenants that could theoretically allow for permanent blacklisting of coins. By being non-recursive, OP_CTV blunts the critique that UTXOs could be forever encumbered by restrictive logic. Conversely, OP_CAT allows for the concatenation of data points, which can be used to build STARK-verified trustless bridges. StarkWare has already highlighted a design for a recursive covenant that maintains bridge state in an OP_RETURN Merkle root, positioning zk-proof verification as a concrete use case.
The implications for Bitcoin’s infrastructure are significant. For the Lightning Network to scale to millions of users, primitives like channel factories and shared UTXOs—both requiring covenant logic—are increasingly viewed as necessities. Channel factories would allow users to open multiple Lightning channels without individual on-chain transactions, reducing base-layer congestion. Furthermore, trustless bridges would allow Bitcoin to compete in the decentralized finance space by removing the need for centralized intermediaries like WBTC, which compromise the permissionless nature of the technology.
Governance power dynamics have shifted in this early phase. While large miners and ETF issuers have remained silent, media influencers have taken the lead in manufacturing the narrative for OP_CAT. This signaling is vital for building the public momentum necessary to move a proposal from ideation to technical review. However, the final decision rests with Core developers, who must navigate the divide between those seeking rapid innovation and those prioritizing protocol ossification. The memory of the “block size wars” remains a potent reminder of the risks associated with contentious changes, leading the community to favor the backwards-compatible soft fork model.
Galaxy Research forecasts that while Bitcoin Core developers may reach a consensus on adding one of these opcodes by 2025, the actual activation would likely lag by another one to two years. This pushes any live implementation into the 2026–2027 timeframe. For now, the power remains firmly with the protocol engineers who demand proof that these upgrades will not compromise the network’s digital sovereignty. As the industry watches for a signal, the focus remains on whether Bitcoin can evolve its engineering without losing the constitutional values of predictability and network fidelity.
Ryan Mitchell serves as a Staff Writer for Just Right News, where he anchors the desk for Cyber, Technology Policy, and Digital Sovereignty. In an era where the digital landscape has become as much a battlefield as any physical territory, Ryan provides a critical conservative lens on the forces shaping the future of American innovation and national security. His work is defined by a commitment to the idea that American leadership in the digital age is not just a matter of economic success, but a necessity for the preservation of global liberty.
Born and raised in Austin, Texas, Ryan’s perspective is deeply rooted in the Lone Star State’s tradition of independence and skepticism of centralized authority. Growing up in a city that transformed from a quiet state capital into a global technology hub, he witnessed firsthand the disruptive power of the tech industry. This upbringing instilled in him a firm belief in free-market principles and the necessity of protecting individual liberties from both government overreach and corporate overstep. His Texan background serves as a foundational compass, guiding his reporting toward stories that emphasize national resilience and the preservation of constitutional values in an increasingly virtual world.
Now based in San Francisco, California, Ryan operates from the epicenter of the very industry he scrutinizes. Living and working in the heart of Silicon Valley allows him to provide “boots on the ground” reporting that few conservative journalists can match. He navigates the cultural and political complexities of the Bay Area to bring Just Right News readers an inside look at the boardrooms and coding labs where the next generation of digital policy is forged. For Ryan, being stationed in San Francisco is a strategic choice; it allows him to challenge the prevailing ideological monoculture of the tech elite from within their own backyard, ensuring that the concerns of middle America are represented in the conversation about our digital future.
His beat—Cyber, Technology Policy, and Digital Sovereignty—covers the high-stakes world of data privacy, artificial intelligence, and the infrastructure of the modern web. Ryan is particularly focused on the concept of digital sovereignty, arguing that for a nation to remain truly free, it must maintain control over its own technological destiny and critical infrastructure. He frequently explores how international regulations and domestic policies impact the ability of American firms to compete without sacrificing the privacy or security of their citizens.
Central to his current body of work is his featured series, “The New Cold War.” Through this project, Ryan examines the escalating technological rivalry between the United States and its global adversaries. He delves into the complexities of state-sponsored hacking, the global race for semiconductor dominance, and the ideological struggle to define the rules of the internet. Ryan views this competition not merely as a commercial race, but as a fundamental defense of Western values against authoritarian digital models. Through his rigorous reporting and principled analysis, Ryan Mitchell ensures that the readers of Just Right News stay informed about the invisible forces defining the 21st century, always advocating for a future where technology serves the cause of freedom.
