| dc.description.abstract (摘要) | 過去幾年來區塊鏈技術蓬勃發展，除了以公開無監理方式運行的比特幣與以太坊外，適合企業或政府組織應用環境，具有管理機制，高效能共識與隱私保護的區塊鏈平台也陸續推出。這些企業區塊鏈平台或者以私有鏈或聯盟鏈網路的形式運作，其中由以太坊衍生出來的Quorum平台，以其特有的隱私交易功能，以及高效能共識機制，獲得矚目，並陸續為國際間一些大型企業或中央銀行採用，進行實驗與場域測試。Quorum平台的私有交易功能，雖然能提供參與者就彼此之間的交易內容進行加密，以保護交易雙方的隱私；但也因此造成其區塊鏈的帳本分為公帳與私帳兩類，參與者之間不再共享單一帳本。伴隨而來的嚴重後果就這些私有交易的安全不易確保。例如雙重支付的查驗因大家的私帳不一致，而有困難。其次，隱私保護與監管需求之間也會面臨挑戰。有鑑於此，本計劃擬針對Quorun平台提出擴充，以密碼學常用的承諾（commitment）方案與零知識證明技術來強化Quorum對交易安全的檢驗能力。此外，將透過標竿範例，發展軟體框架與工具，提供開發Quorum智能合約的安全實務指引，並就監管需求與隱私保護之間取得比較好的平衡，以達到交易內容可隱私保護，但交易結果必需可公開驗證的原則。 | |
| dc.description.abstract (摘要) | In the past few years, blockchain technology has developed vigorously. In addition to Bitcoin and Ethereum operating in an open and unsupervised manner, Blockchain platforms with management mechanisms, high-performance consensus and privacy protection, suitable for the application environment of enterprises or government organizations, have also continued roll out. These enterprise blockchain platforms operate either in the form of private or consortium networks.The Quorum enterprise blockchain platform derived from Ethereum has attracted attention with its unique privacy transaction function and high-performance consensus mechanism, and has been adopted by some large enterprises or central banks for experiments and field tests.The private transaction fetaure of the Quorum platform, although it can provide participants to encrypt each other's transaction content to protect the privacy of both parties to the transaction; however, it also causes its blockchain ledger to be divided into public and private sub-ledgers. Participants no longer share a single ledger. The grave consequences that accompany it are the security of these private transactions. For example, the check of double spending will be difficult because everyone's private sub-ledger will be different. Besides, there will be challenges between privacy protection and supervisory requirements.To address these issues, this project intends to develop an extension of the Quorun platform, and strengthen the Quorum's ability to verify transaction security with a commitment scheme and zero-knowledge proof technology commonly used in cryptography. In addition, we will develop software frameworks and tools through benchmark examples, provide security guidelines for the development of Quorum smart contracts, and achieve a better balance between supervisory needs and privacy protection. Overall, our goal is to support privacy protection of transaction content, but ensure that transaction results must be publicly verifiable. | |
