@mononautical, the founder of mempool, posted on X that Fractal Bitcoin went live on the mainnet a few hours ago. This seems to be a hastily "cloned" copy of Bitcoin Core v24.0.1, with some consensus adjustments and some code "copied" from namecoin and bcash. The main changes are as follows:
-Mixed standard PoW and merged mining blocks;
-30 seconds target block time;
-Continuous difficulty adjustment, copied from bcash;
-The maximum supply of tokens is 210 million;
-The initial block reward is 25 tokens per block;
-Halved every 2.1 million blocks;
-OP_CAT has been activated.
In addition, its premine tokens account for 50% of Fractal Bitcoin's fully diluted supply. If everything goes according to plan, miners will need a full two years (a Fractal Bitcoin halving interval) to earn half of the rewards the founders received on the first day.
He also said that Fractal Bitcoin's Litepaper contains a lot of meaningless technical terms about "virtualization", "recursively", and "scaling in layers", but there is almost no similarity in the actual deployment. Therefore, in his opinion, this is just another shitfork (of Bitcoin).
According to the token economics disclosed by Fractal Bitcoin, the total supply of FB tokens is 210 million, and the specific distribution is: 50% for proof of work (PoW) mining, 15% for the ecosystem treasury, 10% for community grants, 5% for presales, 5% for consultants, and 15% for core contributors. The upper limit of the allocation of the ecosystem treasury and community grants is 10% of the total annual allocation, which is distributed over 10 years. The upper limit of the allocation of consultants is 20% of the total annual allocation, which is distributed over 5 years.
