The Bitcoin network is a peer-to-peer electronic cash system that uses blockchain technology to record all transactions without relying on a central authority or intermediary. It is maintained by thousands of nodes around the world, working together to uphold a public distributed ledger.
Key features of Bitcoin and similar blockchains (such as Fractal Bitcoin) include a fixed supply, transparent transaction records, anonymity (or pseudonymity), and a tamper-resistant design.
These chains typically employ Proof of Work (PoW) or other consensus mechanisms (like Proof of Stake) to ensure the security and consistency of the network.
As the first successful cryptocurrency, Bitcoin pioneered a new category of digital assets and laid the foundation for subsequent blockchain projects and decentralized systems.
Emerging chains like Fractal Bitcoin build on Bitcoin's foundation, aiming to improve transaction efficiency, scalability, and community governance, advancing the development of the digital currency ecosystem.
