# Validators
"While any Fair Witness would do, the prestige of Cavendish was such that a lawyer was hardly necessary" -Robert Heinlein
Validators are the entities that are able to provide attestations for the content of a specific piece of media. In this regard, they are merely a [**Fair Witness**](https://en.wikipedia.org/wiki/Stranger_in_a_Strange_Land#Fair_Witness) that are able to provide verification that a specific event exists on a specific platform with specific metadata. For example, they could attest that a user made a tweet saying "hello world", that this tweet currently has 10 likes and 5 retweets, and the tweet was made at 1:25pm on July 8th, 2024.
The strength of this is, as multiple validators are able to come to consensus on the occurrence of an event, the risk to a user is significantly decreased. Instead of relying on a centralized service to execute on a user's behalf, a quorum of validators can rapidly come to consensus on the existence of an event, and this can be proven onchain and used to execute an action.
Initially, we will rely on a 2 of 3 quorum of validators to attest the existence of an event on a source. We will increase the decentralization and security of this validator network over time, as we prove the viability of this solution.
