Abstract

The present invention provides a method for high-security data transmission of a blockchain. First, a source node device broadcasts a data packet to at least one destination node device and at least two cooperative node devices in the blockchain. The data packet includes a random variable and a transmission data. The cooperative node devices further forward the data packet to the destination node device. When the number of data packets received by the destination node device is equal to the random variable, the cooperative node device sends a report signal to the source node device, and the source node device broadcasts a stop broadcasting request to the blockchain, then the other node devices stop forwarding data packets to the destination node device, and finally the destination node device compares the transmission data of the data packet and selects the data packet with the same transmission data packet to store.
