Consensus Mechanism
The method by which a blockchain network agrees on the current state of the ledger. Common mechanisms include Proof of Work and Proof of Stake.
Why It Matters
A consensus mechanism is a process that ensures all participants in a blockchain network agree on the state of the blockchain. Understanding this is crucial for assessing how different cryptocurrencies maintain security and integrity.
Example
For example, Bitcoin uses a proof-of-work mechanism, requiring miners to solve complex problems to validate transactions. This consensus ensures that all valid transactions are recorded accurately.
Beginner Context
For newcomers, grasping the concept of consensus mechanisms is fundamental to understanding how blockchain technology works. It helps explain the security protocols underlying various cryptocurrencies.

Burn
The permanent removal of tokens from circulation, typically by sending them to an inaccessible wallet address. Burning reduces supply and can increase scarcity.
