Avalanche Consensus Algorithm

The Avalanche Consensus Algorithm is a way for many computers (or nodes) in a network to quickly agree on data, such as which transactions are valid. Instead of relying on a single authority, each node randomly samples a few others to see what they think. If most nodes agree on a decision after several rounds of sampling, the network collectively approves it. This process is fast, scalable, and resilient to dishonesty, enabling secure, decentralized transactions without heavy energy use. It’s like a group of people reaching consensus by asking a few friends repeatedly until everyone agrees.
