Distributed Validator Technology (DVT) refers to a system where the process of validating or confirming information is spread out across multiple computers or nodes, rather than being handled by a single central authority.
A validator’s private key is split across several node operators enabling the duties and responsibilities of a validator to be distributed and shared across a cluster of node operators, instead of a single node. Imagine you have a big puzzle to solve. Instead of one person trying to solve it alone, the task is divided among several people, each working on a different part of the puzzle. Once everyone completes their part, their solutions are combined to form the complete picture.
This approach has several benefits, including increased security, transparency, and resistance to tampering, because altering the information would require changing the majority of the copies stored across all these different nodes, which is extremely difficult.
