Byzantine Fault Tolerance (BFT) is a concept in cryptocurrency that refers to the ability of a system to operate correctly and reach a consensus even in the presence of faulty nodes or malicious actors. This is important in decentralized systems like blockchain, where multiple nodes are involved in validating transactions and maintaining the network.
In a BFT system, all nodes communicate with each other to agree on the validity of transactions. If some nodes provide incorrect information or act maliciously, the system can still continue to function properly as long as a sufficient majority of nodes are honest and in agreement.
By using cryptographic techniques and consensus algorithms, BFT ensures that the network remains secure and operational, even if some nodes try to disrupt the process. This helps in maintaining the integrity and reliability of the cryptocurrency system, making it resistant to attacks and ensuring that transactions are processed correctly.
Overall, BFT plays a crucial role in ensuring the trustworthiness and resilience of decentralized systems, particularly in the realm of cryptocurrency where security and reliability are paramount.
