论文摘要
这项工作是关于两种技术之间的相互影响：数据库和区块链。它解决了两个问题：1。数据库技术如何影响区块链技术的发展？和2。区块链技术如何影响某些现代数据库中新功能的引入？对于第一个问题，我们解释了数据库技术如何通过解锁酸（原子能，一致性，隔离和耐用性）交易一致性，丰富的查询，实时分析和低延迟来促进区块链技术。我们解释了以数据库而闻名的CAP（一致性，可用性，分区公差）定理如何影响区块链系统的DC（权力下放，一致性，可伸缩性）定理。通过使用类似的松弛方法，因为它被用于证明CAP定理的证明，我们假设了“ DCS-可满足性的猜想”。对于第二个问题，我们审查了专门为区块链设计的不同数据库，并提供大多数区块链功能，例如不变性，隐私，审查阻力以及数据库功能。
This work is about the mutual influence between two technologies: Databases and Blockchain. It addresses two questions: 1. How the database technology has influenced the development of blockchain technology?, and 2. How blockchain technology has influenced the introduction of new functionalities in some modern databases? For the first question, we explain how database technology contributes to blockchain technology by unlocking different features such as ACID (Atomicity, Consistency, Isolation, and Durability) transactional consistency, rich queries, real-time analytics, and low latency. We explain how the CAP (Consistency, Availability, Partition tolerance) theorem known for databases influenced the DCS (Decentralization, Consistency, Scalability) theorem for the blockchain systems. By using an analogous relaxation approach as it was used for the proof of the CAP theorem, we postulate a "DCS-satisfiability conjecture." For the second question, we review different databases that are designed specifically for blockchain and provide most of the blockchain functionality like immutability, privacy, censorship resistance, along with database features.
