## What it is
jmzkChain is a C++ blockchain node implementation developed by Hangzhou Yuliankeji (Vastchain), described as a 'Boost Engine for Regulation and Security'. It exposes an RPC interface for running nodes and building applications, with an official JavaScript SDK for web, backend, and mobile clients.

## Use cases
- run a jmzkChain blockchain node
- build blockchain applications with the JavaScript SDK
- deploy a consortium blockchain for trusted data sharing
- integrate blockchain-backed evidence storage for public security or judicial workflows
- serve blockchain RPC requests behind a reverse proxy

## When to choose
- you need to run or develop against the jmzkChain/Vastchain consortium blockchain
- you want a blockchain platform tailored to regulation and security use cases in China
- you are building apps with the official jmzk JavaScript SDK

## When to avoid
- you need a general-purpose public blockchain like Ethereum or Bitcoin
- you require a permissive open-source license (the license is non-standard)
- you need active community development - the project's latest release was in 2022
