Cloud native block chain processing method and device, equipment and medium

The invention relates to a cloud native block chain processing method and device, equipment and a medium, and the method comprises the steps: dividing a block chain network into a plurality of sub-block chains according to a fragmentation technology, and distributing transactions to different sub-block chains according to a specific rule or the characteristics of the transactions; the optimized Byzantine fault-tolerant algorithm determines the number of the maximum fault node number f allowed in the block chain system through message exchange in the pre-preparation stage, the preparation stage and the submission stage; selecting a verification node; voting to select trusted consensus nodes from nodes in the block chain network; and according to an alternate block output mode, the nodes participating in the consensus are ensured to alternately generate blocks. According to the invention, the block chain network is divided into a plurality of sub-block chains, so that each sub-block chain can process a part of
