Abstract: Disclosed is a directed acyclic graph-account-wise transaction chain (DAG-AWTC) ledger system using a byzantine fault tolerance (BFT) verification consensus scheme. The DAG-AWTC ledger system includes a consensus target transaction setting module for selecting a consensus target transaction for which a BFT consensus is to be executed with respect to a transaction of a DAG-AWTC to set the selected consensus target transaction in real time, and outputting the real-time set consensus target transaction to a BFT consensus execution module. According to the DAG-AWTC ledger system using the BFT verification consensus scheme described above, a BFT consensus scheme, which is a verification consensus scheme, is applied to a parallel DAG ledger structure, so that fast transaction processing as well as rapid verification and integrity of information are ensured. In more detail, a temporal setting assuming that distribution is sufficiently achieved for a BFT verification consensus is set, so that the BFT verification consensus and the transaction processing are respectively performed in a parallel manner. In other words, since the BFT verification consensus is performed as a separate background processing while processing the transaction, the BFT verification consensus is possible without reducing a fast transaction processing speed of the DAG-AWTC ledger structure.
