Validations

Randomly selected nodes can also act as validators when they receive data. They can validate the information and gossip their verdict to the rest based on the rules defined in the application (what is known as DNA) and based on identity proofs. Events can be marked as erroneous, as well as an agent can be flagged and the other agents may not want to interact with him in the future. To avoid this, agents can first validate their actions before executing them. This generates a decentralized validation process, without the need for consensus, so it can be fast and effective. In the following image, the validation flow is detailed.
