UniSat founder Lorenzo wrote that Fractal, a Bitcoin scaling solution, reset OP_CAT on the testnet today and will activate OP_CAT on the mainnet on the first day of September. It is currently developing 3-5 methods of cross-chain bridges to cross assets from the Bitcoin mainnet to Fractal. Fractal will have a developer program that may be much larger than any form of airdrop, which will be aimed at projects that have an impact on the real-world adoption of Bitcoin scaling. It will support BRC-20, Runes and some other natively supported Bitcoin protocols, and use a modular approach to make them interoperable. It will gradually enable an advanced Bitcoin virtual machine to enable applications to be built within TapRoot. It has also tried an off-chain execution model in BRC-20-Swap, which will become Fractal Swap or a possible PizzaSwap.
