1. Abstract

As characteristic of blockchain, it is natural for data to gradually accumulate. However, if too many blocks are stacked, query performance for particular block is degraded. This is called “Blockchaun Bloat(State Bloat)”, which is not a distant future problem.

We developed LING to solve the problems of data processing speed and scalability considering large-scale blockchain. LING is a high-performance K-V(Key-Value) database system that guarantees uniform performance of large-scale blockchain data.

This document describes the specification of LING DID Method. And this is a draft document and will be updated.

2. Target System(s)

(1) Decentralized environment

Suitable for Decentralized environments.

• LING is database system based LevelDB among K-V databases.
• K-V database stores data in Tree structure. Most LevelDB generally stores data in B+Tree structure, it is known as a way to store a lot of data efficiently.

(2) Cloud environment

Suitable for applications that process large amounts of data and provide real-time services in a cloud environment.
