| Abstract: | 區塊鏈是一種具有透明性的分散式帳本技術，並且其市場正在快速發展，但缺乏隱私性被指出是一個嚴重問題。區塊鏈的隱私保護機實現了對使用者在區塊鏈系統中的隱私保護，例如Monero、Zcash以及Blockmaze。Blockmaze是一種。它還通過zk-SNARKs實現了發送方和接收方之間的不可鏈接性以及交易金額和用戶餘額的匿名性。本研究聚焦於基於賬戶模型區塊鏈的隱私保護機制，如Blockmaze。Blockmaze採用了zk-SNARK來增強隱私保護能力，這與基於UTXO模型的Zcash在以太坊系統中的應用相同，然而，BlockMaze在存儲和計算成本上比以太坊更昂貴。本文提出了一種改良的BlockMaze方案，以在保持相同安全水平的情況下節省這些成本。
Blockchain is a distributed ledger technology with transparency and developing rapidly the market of Blockchain is getting huge, but the lack of privacy is pointed out as a serious problem. Privacy-preserving blockchains achieve privacy protection for users in blockchain systems such as Monero, Zcash, and Blockmaze which is an account-based blockchain that also achieves Unlinkability between a sender and a receiver and anonymity of transaction amount and balance of users with zk-SNARKs. The research focuses on account-based privacy-preserving blockchains such as Blockmaze. Blockmaze adapted zk-SNARK to enhance privacy level based on the Ethereum system same as Zcash in the UTXO model, however, the cost of storage and computation in BlockMaze is much more expensive rather than Ethereum. This paper suggests an Updated BlockMaze scheme to save these costs with the same security level. |
