The CLARITY Act, formally the Digital Asset Market Clarity Act, is a proposed U.S. market structure bill that would create a federal framework for how digital assets are issued, traded and regulated. It focuses on how crypto firms would comply with federal law and which regulators they would need to register with. The measure is aimed at standardizing digital asset regulation across the U.S. market.

Bitcoin’s supply is capped at 21 million coins, a limit embedded in the network’s code by its creator, Satoshi Nakamoto. Once all 21 million bitcoin are mined, no new bitcoin will be created. The network is still expected to operate largely as it does now, with miners shifting from newly issued bitcoin to transaction fees for revenue.
