Decentralized consensus is the process by which a distributed network of computers agrees on the validity of transactions and the current state of a ledger without relying on a central authority. This mechanism is fundamental to the operation of most cryptocurrencies and blockchain networks, ensuring data integrity and security. It allows for a shared, immutable record of transactions that is resistant to censorship and single points of failure.
Context
The ongoing development and comparison of various decentralized consensus algorithms, such as Proof-of-Work and Proof-of-Stake, remain a central theme in blockchain technology news. Debates frequently address the trade-offs between security, scalability, and energy consumption associated with different approaches.
