TiDB + Blockchain = ?

  • Team name: 早日暴富

  • Authors: Jack Ma, Chen Xi, Jack Yu

  • Project process: WIP

Project description

Using the TiDB Compute Engine to Read Blockchain Data.

Background & motivation

Blockchain is more like a decentralized distributed database, however, it lacks SQL support, and this project tries to combine the two by using TiDB compute layer to access Blockchain data directly.

Project design

Let's take ethereum as an example, ethereum officially uses geth as a client and the loaded data is stored in local goleveldb, TiDB can naturally use goleveldb as a storage engine. At the same time, there are different storage engines such as TiKV, TiFlash, etc. in a cluster, and after accessing to Ethernet, you can use TiDB as the entry point to read the transaction data of Ethernet directly, instead of downloading the Ethernet data and then importing it into a relational database for reading. In addition, it is also possible to perform ETL of Ethernet data directly inside TiDB, and a simple SQL can import Ethernet data into TiKV/TiFlash to facilitate HTAP type business access.
