Distributed Ledger Systems
Collaborators: Prof. Show-Shiow Tzeng, Prof. Li-Chun Wang
中本聰(Satoshi Nakamoto)於 2008 年發表比特幣(Bitcoins)白皮書,提出了一個不需信賴中央主管機關的分散式現金帳本系統( Distributed Cash Ledger System)。比特幣的主要概念為去中心化( Decentralization) , 意即不存在一個集中式系統儲存著所有交易紀錄。相反的,比特幣系統將同一個交易紀錄儲存在一個分散式網路上的各個節點之中。當儲存交易紀錄的節點愈多時,比特幣的交易紀 錄就愈不容易被竄改,整個交易系統也就愈安全。區塊鏈為儲存比特幣的資料結構,他具有不可竄改及分散式的特性。我們的研究在區塊鏈基礎技術之上,包含了挖礦、共識機制及分片。以下將詳細說明。
