    摘要: Hyperledger Fabric 是目前最著名的許可區塊鏈之一。 由於其樂觀並發控制 (OCC) 功能，它可以實現交易並行處理。但是，OCC 可能會造成交易由於多版本並行控制讀取衝突 (MVCCRC) 而失敗。為了解決 MVCCRC 問題，提出了以下方法：KS 交易隊列和隨機延遲重傳。這些方法旨在避免將容易發生 MVCCRC 的交易並行處理，從而使 MVCCRC 發生率減少最高達 97%，並將每秒有效交易數增加最高達 11 倍。此外， 還引入了擁塞控制來防止 Hyperledger Fabric 網絡擁塞。
    Hyperledger Fabric is currently one of the most prominent permissioned blockchains. It enables concurrent transaction processing due to its Optimistic Concurrency Control (OCC) feature. However, for OCC, transactions can fail due to conflicts arising from Multi-Version Concurrency Control Read conflicts (MVCCRC). To address the issue of MVCCRC, the following methods have been proposed: KS transaction queues and retransmission with random delay. These methods aim to avoid concurrent processing of transactions that are prone to MVCCRC, thereby resulting in a reduction of MVCCRC occurrences by up to 97% and increase in VTPS (Valid Transactions Per Second) by up to 11X. Additionally, congestion control methods have been introduced to prevent network congestion in the Hyperledger Fabric network.
