Fractal Bitcoin, a Bitcoin expansion solution, posted on the X platform that the mainnet will be launched in about 11 hours. The total supply of FB tokens is 210 million, with the specific distribution being: 50% for proof-of-work (PoW) mining, 15% for the ecosystem treasury, 10% for community grants, 5% for presales, 5% for advisors, and 15% for core contributors. The allocation limit for the ecosystem treasury and community grants is 10% of the total annual allocation, which is distributed over 10 years. The allocation limit for advisors is 20% of the total annual allocation, which is distributed over 5 years. This approach is designed to provide long-term support and sustainability for the Fractal ecosystem.
