How Does a Consortium Blockchain Achieve Consensus?

A consortium blockchain typically uses a consensus mechanism like Delegated Proof-of-Stake (DPoS) or a Byzantine Fault Tolerance (BFT) variant, such as Practical Byzantine Fault Tolerance (pBFT). Consensus is achieved by a pre-selected, limited set of trusted validator nodes, which are usually the member organizations.

These nodes validate transactions and propose new blocks. A supermajority of these trusted nodes must agree on the block's validity for it to be added to the chain.

This approach provides high transaction throughput and faster finality compared to public chains.
