Practical overview
When it fits
Use the node repository when setting up jmzkChain node software, or consult its JavaScript SDK reference when building an application that uses jmzkChain. For production network access, account for the repository's reverse-proxy recommendation.
Who it is for
- Teams operating a jmzkChain node.
- Developers building web, backend, Android or iOS applications for jmzkChain.
Documented uses
- Run a node for a jmzkChain network.
- Use the JavaScript SDK as the application-development route for supported web, backend and mobile targets.
- Plan a reverse-proxy layer for network-facing access to node RPC.
Requirements & limits
- The node software is written in C++; the repository separately identifies JavaScript as the application SDK.
- The RPC interface is intended for local networks and lacks rate limiting and security checks, according to the repository.
- Listed operating systems include specified minimum versions, with Fedora 27, Ubuntu 18.04 and macOS 10.13.x recommended.
- The repository advises using a reverse proxy such as nginx for requests served to a production network, but does not give a complete configuration.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Choose a supported jmzkChain host platform
Check whether a host uses an operating system listed as supported by jmzkChain before planning node use.
Before you start
- A host running one of the operating systems listed in the jmzkChain README.
Steps
Identify the host operating system and version.
Compare it with the README's supported list: Amazon 2017.09 or higher, CentOS 7, Fedora 25 or higher, Mint 18, Ubuntu 16.04 or higher, or macOS Darwin 10.12 or higher.
Use the documented recommendations when applicable: Fedora 27, Ubuntu 18.04, or macOS 10.13.x.
Expected outcome
You can determine whether the host matches a listed jmzkChain platform.
Guide limitations
- The README does not provide node installation, build, or startup steps.
- The platform list does not establish support for operating systems or versions not listed.
Plan network access to a jmzkChain node RPC interface
Plan a reverse-proxy layer when serving requests to a jmzkChain node's RPC interface.
Before you start
- A jmzkChain node whose RPC interface will serve requests.
- A reverse proxy server; nginx is given as an example.
Steps
Treat the RPC interface as intended for a local network, not direct Internet exposure.
Plan to use a reverse proxy server such as nginx to serve requests to the node RPC interface.
Account for the README's warning that the RPC interface does not provide features such as rate limiting and security checks.
Expected outcome
The access plan places a reverse proxy in front of the RPC interface rather than relying on the interface alone for Internet-facing access.
Guide limitations
- No complete proxy configuration or implementation steps are provided.
- The README does not describe specific security controls or guarantee that a proxy configuration is secure.
