TechFlow reports that on September 9, mononaut, founder of Mempool, posted on social media alleging that Fractal Bitcoin, which recently launched its mainnet, appears to be a hastily cloned version of Bitcoin Core v24.0.1. The project made minor consensus changes and borrowed some code from Namecoin and BCash. Key modifications include: hybrid standard PoW with merged mining, a 30-second block time, continuous difficulty adjustment, a maximum supply of 210 million coins, an initial block reward of 25 coins, halving every 2.1 million blocks, and activation of OP_CAT.
Notably, the chain features a pre-mine of up to 50%, with these pre-mined coins immediately spendable. If everything proceeds as planned, miners will require two full fractal halving cycles—about two years—to mine an amount equal to half of what the founding team allocated for themselves on day one. Mononaut also pointed out that the Fractal Bitcoin whitepaper is filled with meaningless technical jargon such as "virtualization" and "recursive layered scaling," and that the actual implementation has almost nothing to do with the described concepts.
