The situation is a modern replay of a 19th-century fight over about two feet of iron... 🛤️ That fight was the "break of gauge"—a point of total paralysis where non-interoperable rail networks created a crippling tax on commerce. This is the single problem that will decide if the GENIUS Act creates an open financial future or just a new set of walled gardens. The Act meticulously regulates the coin but forgets to standardize the track, meaning value will roll smoothly until it hits the border of a corporate chain, and then stop. The decisive battle is at the network level. Stripe is building its Tempo blockchain, Circle has Arc. These corporate chains are today's different-gauge tracks. Without legally enforced interoperability, we will have simply rebuilt the same siloed payment systems we have today, just with newer technology. How open networks become captive—Breaking interoperability is dangerously easy. A dominant network won't just block a rival. They'll have a ready-made excuse: connecting is "too technically challenging," "unprofitable," or a "compliance risk". It can be done subtly, disguised as a necessary technical upgrade or a prudent new rule. This is how an open highway becomes a captive one. From "May" to "Must"—The solution is to treat interoperability as essential public infrastructure. The GENIUS Act says regulators "may" prescribe standards, a "dangerously gentle word" in a market defined by network effects. That word has to become "must." The choice is simple: build an open highway for all, or pave a faster road to a single kingdom. Full article: [tinyurl.com](https://tinyurl.com/2t2p2vub)
