Immutable and Democratic Data in permissionless Peer-to-Peer Systems
This addresses data storage challenges in decentralized systems for applications requiring immutable and democratic data management, but it appears incremental as it builds on existing DLTs and databases.
The paper tackles the problem of persisting data without a central authority by exploring permissionless peer-to-peer networks, primarily using Distributed Ledger Technologies (DLTs) and their combination with conventional databases, and implements two prototypes evaluated against conventional databases.
Conventional data storage methods like SQL and NoSQL offer a huge amount of possibilities with one major disadvantage, having to use a centralized authority. This authority may be in the form of a centralized or decentralized master server or a permissioned peer-to-peer setting. This paper looks at different technologies on how to persist data without using a central authority, mainly looking at permissionless peer-to-peer networks, primarily Distributed Ledger Technologies (DLTs) and a combination of DLTs with conventional databases. Afterwards it is shown how a system like this might be implemented in two prototypes which are then evaluated against conventional databases.
