Abstract
Provided are method and apparatus for creating and adding blocks based on a structured directed acyclic graph (DAG) and building a distributed ledger. In the present invention, a chain structure is extended to the structured DAG while Proof of Work (PoW) and Nakamoto consensus are used. Objectives of the present invention are, to scale up the capacity, shorten the latency, deconcentrate mining power and increase the chance of processing transactions with low or no fees without compromising security and decentralization.
