What Is Concensus Mechanism In Cryptocurrency?
A consensus mechanism is like a voting system that helps a blockchain network agree on the state of the network, ensuring everyone's on the same page. It's a crucial part of decentralized systems, allowing nodes to validate transactions and add new blocks to the chain.

Think of it like a group project where everyone needs to agree on the final outcome. In crypto, consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) help achieve this agreement, securing the network and verifying transactions.
Some popular consensus mechanisms include:
- Proof of Work (PoW): nodes solve complex math problems to validate transactions.
- Proof of Stake (PoS): nodes "stake" their own cryptocurrency to validate transactions.
- Delegated Proof of Stake (DPoS): users vote for validators to secure the network.
- Practical Byzantine Fault Tolerance (PBFT): nodes vote on transaction validity
These mechanisms ensure the integrity and security of the blockchain, preventing double-spending and other malicious activities.
