Definition ∞ Bitcoin transactions represent transfers of value across the Bitcoin blockchain network. Each transaction involves cryptographic signatures to authorize the movement of Bitcoin from one address to another. These operations are recorded in blocks and verified by network participants. The integrity of these transfers relies on the decentralized consensus mechanism.
Context ∞ Bitcoin transactions frequently appear in news concerning network congestion, transaction fees, and the overall efficiency of the blockchain. Debates persist regarding scalability solutions aimed at increasing transaction throughput without compromising decentralization. The cost and speed of these operations remain key factors influencing Bitcoin’s utility as a payment system and its public perception.
