Which mechanism is commonly used to validate transactions in Bitcoin?
- Byzantine Fault Tolerance (BFT)
- Delegated Proof of Stake (DPoS)
- Proof of Stake (PoS)
- Proof of Work (PoW)
Bitcoin relies on the Proof of Work (PoW) consensus mechanism to validate transactions. Miners compete to solve complex mathematical puzzles, and the first to solve it gets the right to add a new block to the blockchain. This energy-intensive process ensures security and decentralization. Recognizing PoW as a validation mechanism is essential for understanding the operation of Bitcoin and similar cryptocurrencies.__________________________________________________
