An permissionless blockchain consensus method with adjusting block weight, comprising: setting weights of all blocks in the permissionless blockchain to the same initial value; determining parent edges(forward reference-edges) of any one of blocks in the permissionless blockchain according to the blockchain topology; detecting whether a first judgment block x is in blocks contained by the parent edge of a block b; if yes, determining that the block b is an unstable block and transferring to next step, otherwise, determining the block b is a stable block and transferring to a pivot chain consensus step; and detecting whether a second judgment blocky is in the stable block contained by the parent edge of the block b; if yes, determining the block b is a readjusted block and transferring to a weight adjustment step, otherwise, determining the block b is a stable block and transferring to the pivot chain consensus step.

The present invention relates to a block sequencing method based on a tree-graph structure, comprising of: linking all blocks into a tree-graph structure according to reference relationships; selecting one pivot chain from the tree-graph structure and taking all blocks in the pivot chain as pivot blocks; dividing all blocks into a plurality of Epochs according to a time sequence arrangement of the pivot blocks; sorting the blocks in the Epoch to obtain a set sequence of the Epoch in time sequence; and obtaining a global sequence of all blocks of the tree-graph structure based on all set sequences. The present invention also relates to a block sequencing system based on the tree-graph structure, a data processing terminal for sequencing blocks by the block sequencing method, and a P2P network using the data processing terminal.
