Abstract
A ledger verifiable pruning system includes a skewed Merkle tree production module in which according to a linked list scheme, root hash value Rof a previous sub-tree is included in data block T, data block Tin which root has value Ris included is hashed, thereby obtaining h(T), obtained h(T) and root hash value Rof the previous sub-tree are summated and then hashed, thereby obtaining h(h(T)|R), and obtained h(h(T)|R) is successively added to respective nodes of a binary Merkle tree structure to expanding and produces a skewed Merkle tree.
