Bitcoin’s blockchain is secured by its decentralized network and cryptographic protection. However, the safety of your bitcoin depends on how you store and manage it. Use a reputable platform, enable two-step authentication, and never share your private keys. Nodes store all transactions on a public ledger called the Bitcoin blockchain, which serves as a fully accessible, transparent database. This digital ledger stores all bitcoin transactions as well as user balances in the form of unspent transaction outputs, or UTXOs. Once the system writes something to the ledger, it is effectively permanent, since it can never be changed, only updated.

Nodes are distributed across the globe and maintain their own personal copy of the ledger. This important factor means there is no single point of failure. Even if 99% of nodes go down, a single node could recover the entire Bitcoin blockchain. Bitcoin (BTC) is the world’s first globally viable cryptocurrency built with blockchain technology.
