The invention discloses a block chain-based
forestry carbon sink carbon asset public service method, which comprises the following steps that: a user terminal logs in a forest right
carbon sink subsystem and registers a forest right
certificate to which the user terminal belongs; the forest right
carbon sink subsystem inquires and compares forest right certificates,
forestry workers confirm right, the
satellite remote sensing subsystem photographs according to a designated area and analyzes information, the
expert evaluation subsystem generates an expert report, the third-party carbon value measurement and calculation subsystem generates a carbon value evaluation report, and the third-party carbon value measurement and calculation subsystem generates a carbon value evaluation report. Environmental
authentication center subsystems of the Ministry of National
Environmental Protection generate an
authentication report, and each subsystem stores a corresponding file in a block chain for evidence storage; and after receiving the
authentication report, the forest right carbon sink subsystem sends a message to the user terminal to get a corresponding carbon
ticket. According to the method, the
forestry carbon
ticket is generated by integrating authentication of a plurality of processes, and each process is connected in series by using the block chain evidence storage to ensure that
process information is not tampered, so that the authenticity of the carbon
ticket is ensured, and carbon ticket transaction, pledge, cashing, counteracting and the like are ensured to be smoothly carried out.
