The invention provides an illegal data uplink identification method and device based on a block chain, the method is applied to an identification chain in the block chain, and the method comprises the following steps: generating a smart contract; negotiating with the identified chain, and filling identification parameters into the smart contract according to a negotiation result; the token is sent to an identified chain IDBC, so that the identified chain IDBC returns data information stored in an interstellar file system IPFS and a hash value generated by the token to the identification chain; selecting an identification node based on a reputation-based node random selection algorithm; and the received hash value is broadcasted and notified to the identification nodes, so that each identification node downloads the data information through the hash value and identifies the data information. According to the method provided by the invention, identification of illegal data chaining is realized, management of th
