At Fidelity Investments’ headquarters in Boston, a group of Bitcoin enthusiasts gathered not to marvel at price charts but to tackle the deeper issues of scaling and sustaining the world’s largest cryptocurrency. This event, called OP_NEXT, marked the first Bitcoin-specific scaling conference in years and attracted a niche crowd of developers and Bitcoin advocates. Will Foxley, the event’s host, emphasized the mission: bringing Bitcoin to a broader audience—potentially “the next billion” users.

Unlike mainstream crypto conferences, which often feature flashy corporate displays and investment pitches, OP_NEXT offered a quieter, tech-focused atmosphere where developers discussed how to make Bitcoin more adaptable, secure, and efficient. Paul Sztorc of Layer2 Labs highlighted the stakes, suggesting that Bitcoin risks being outpaced if it doesn’t evolve quickly enough. But innovation in Bitcoin’s network isn’t straightforward. Without a central authority, changes rely on community consensus—a slow and sometimes frustrating process for developers.

Two significant upgrades, SegWit and Taproot, changed Bitcoin’s transaction capabilities in recent years, but progress has since stalled, creating a sense of “ossification” in Bitcoin Core, the foundational software. Developers present debated whether more frequent updates could jeopardize Bitcoin’s stability. As some voiced support for rapid changes, others resisted, jokingly proposing “soft forks every day” to underscore the risks of over-complicating the network.

Proposals for new features, known as Bitcoin Improvement Proposals (BIPs), must endure a long review and approval journey. This cautious approach is meant to avoid disrupting Bitcoin’s stability, even if it slows innovation. A recent proposal, BIP-347 or OP_CAT, suggests reintroducing a function that was removed in Bitcoin’s early days. Proponents argue this feature could bring smart contract capabilities to Bitcoin, putting it closer in functionality to Ethereum. But some, like developer Portland HODL, warn against adding features that could introduce unforeseen problems, or “unknown unknowns.”

Throughout the conference, the limits of Bitcoin’s decentralized governance emerged as a major theme. Despite strong opinions on proposed changes, there remains no clear process for achieving consensus, leaving questions about how and when the community can align on upgrades. The challenge of improving Bitcoin while maintaining its core integrity looms large, and for now, there’s no single answer on who decides its future.
