Bitcoin Security

Definition ∞ Bitcoin security describes the measures that protect the Bitcoin network and its transactions from compromise. This involves cryptographic methods, a distributed network of validating nodes, and the economic incentives of mining which collectively secure the ledger. The robust proof-of-work mechanism makes altering historical transactions computationally impractical, thereby preserving data integrity and resistance to censorship.
Context ∞ Discussions around Bitcoin security frequently address its resistance to 51% attacks and the ongoing debate concerning energy consumption for its proof-of-work system. News often highlights advancements in cryptographic techniques or potential vulnerabilities that might arise from quantum computing developments. Understanding these elements is crucial for assessing the long-term viability and stability of the leading digital asset.
