Validator Node

The validator node is a server that performs PoT to provide rewards to media node operators for resource provision in the VDN. All media nodes periodically send key statistics on the media streams they have sent and received to the validator node. The validator node receives this data, collects it, and verifies whether the traffic information sent by each media node is valid by comparing it with the traffic information sent by the client. All received data is stored in IPFS, and the final validated data is normalized and recorded on the blockchain.
