⼀個基於超級帳本區塊鏈之時間銀⾏系統及其動態加厚信息配對⽅法

Abstract

本文基於厚度動態匹配市場算法，提出了一種區塊鏈上時間銀行(Time Bank) 的實現方法。論文由兩部分組成，其一是在 Hyperledger Fabric（Fabric）平台上實現 Time Bank 系統，Fabric 是眾多許可式 (Permissioned) 區塊鏈平台之一。提供身份證書機制和可擴展的網絡結構是 Fabric 區塊鏈平台的特色。時間銀行系統的成員需要進行身份審查，以使系統更加安全。通過時間銀行交換服務也會增強社區成員之間的互動。故 Fabric 被視為是實現時間銀行系統適合的區塊鏈平台。其次，我們認為利用等待時間可以加厚動態匹配市場，並利⽤這一概念設計出動態調整策略（Dynamic Tuning Strategy: DTS）。根據市場規模，DTS 將決定每次匹配應執行或等待。實驗證實較厚的交易市場可使節點具有更多鏈接並且更容易匹配。

This thesis presents a blockchain based Time Bank realization using thickness dynamic matching algorithm. This work consists of the following two parts: (1) A realization of the Time Bank System on the Hyperledger Fabric (or simply called Fabric) platform. Fabric is one of the well-known permissioned blockchain platforms. Fabric provides the identity certification mechanism and has an extendable network structure under the blockchain. Members of a Time Bank system have to go through an identity checking process for making the personnel of the system more secure. The exchange of services through Time Bank systems also warms the members’communities. (2) On the basis of using waiting time to thicken the dynamic matching market, a Dynamic Tuning Strategy (DTS) for enhancing matching performance, is proposed. According to the market size, DTS helps decide to do a match or to wait for a later chance in each run. Experimental results show that thicker market makes on-chain nodes have more links and is easier to find a match.
