Fractal Bitcoin (FB) is a Layer 2 solution designed to enhance Bitcoin's scalability and functionality. It operates as a sidechain, directly utilizing Bitcoin's core code to create multiple layers that mirror the original blockchain. This structure allows for infinite scaling without compromising Bitcoin's security or decentralization.
Fractal Bitcoin introduces several key features:
1. Recursive Layering: This technique exponentially increases the network's scalability potential, enabling up to 20 times the transaction capacity per layer compared to Bitcoin's base layer.
2. Faster Block Confirmations: Fractal achieves block confirmation times of less than 30 seconds, significantly reducing transaction times compared to Bitcoin's 10-minute intervals.
3. Smart Contract Support: By reintroducing the OP_CAT opcode, Fractal enables limited smart contract functionality, allowing for more complex transactions such as token creation and decentralized applications (dApps).
4. Merged Mining: Through a process called Cadence Mining, miners can mine both Bitcoin and Fractal simultaneously, securing both blockchains without additional energy expenditure.
