What is Fractal Bitcoin?
Fractal Bitcoin (FB) is a scaling network built on the Bitcoin Core codebase. It runs as a sidechain alongside the Bitcoin mainnet, aiming to increase throughput and faster block confirmations while staying close to Bitcoin-native constructs rather than adopting EVM compatibility. It supports Bitcoin-style assets and uses a merged-mining structure with Bitcoin to help secure the network. FB is the native coin of the Fractal Bitcoin network, used to pay fees and reward miners. It has a capped supply of 210 million tokens. The project is led by the team behind the UniSat wallet along with other core contributors. Fractal Bitcoin's mainnet launched in September 2024, so it is a young network and its ecosystem is still developing. As with any new Bitcoin scaling approach, long-term adoption is still being established. You can follow the Fractal Bitcoin price and hold FB in a self-custody wallet.
