For example, all operators (for example, 10 total operators) cooperate with each other to verify the truly agreed home 2 roaming resource sharing information, and a new block is formed as a candidate block after the verification is passed.
In step 406, the candidate blocks that have achieved the true consensus through the resource request consensus mechanism and pass the verification through the verification mechanism are sequentially written into the resource request block chain.
