An experimental smart contract blockchain network
JellyChain1 is a blockchain network platform that supports smart contracts and can act as a payment system/cryptocurrency. It is originally and still is made for experimental and educational purposes, you can have a brief look at its core ideas by following the instructions below.
- NodeJS v16 or higher.
- Latest release of npm.
A system that is running Windows, Linux, or MacOS with a dual-core CPU and 8GB of RAM with a mediocre SSD/HDD should be enough.
First, download the latest release from:
Extract the zip file, in the JellyChain1 folder, open up your terminal and install the required packages through npm:
npm install
If you haven't had a JellyChain1 key pair before, hop over to ./utils/, on the command line, type:
node keygen.js
And it will generate an address, a public key and a private key for you.
In config.json, change the props for your needs:
{
"PORT": /*PORT that your node will run on, default is 3000*/,
"RPC_PORT": /*PORT that the RPC server will run on, default is 5000*/,
"PEERS": /*An array containing peers' address that the node will connect with, default is an empty array*/,
"MY_ADDRESS": /*A string containing the node's address, default is "localhost:3000"*/,
"PRIVATE_KEY": /*A string containing a private key*/,
"ENABLE_MINING": /*Leave true if you want to mine, default is false*/
"ENABLE_LOGGING": /*Leave true if you want to log out contract logs, default is false*/,
"ENABLE_RPC": /*Leave true if you want to run a RPC server, default is false*/,
"ENABLE_CHAIN_REQUEST": /*Leave true if you want to sync chain from others, default is false*/
}To see an example, config.json already has some data set for you to have a look at.
After everything is all set, simply type node . to run the node.
This process will need you to run an RPC server, basically leave true in ENABLE_RPC in config.json to enable it.
To properly interact with the node, you should use the JSON-RPC apis, especially if you are creating dapps. To get started, check out docs for JSON-RPC APIs here.
Note: This feature is still in its early stages, things might change when a stable release is ready.
Located under Clusters/zerodowtime.js:
This module runs in the background.
All you have to do is run/start the zero-downtime.js source code and point your RPC Client/Server and the blockchain server to anyone of the worker ports you will see in your terminal and enjoy. Don't forget to get your keypair first.
Smart contract is still a fairly new feature in JellyChain1. It is only a proof of concept currently and is likely going to change in the future, but for now, you can read this document on creating smart contracts using a small language I have created called jellyscript.
Remember to only use it for experimental purposes, I can not guarantee that this feature will be changed or not in the future. The language is also really limited and far from ready.
Note that this is an experimental project which is still under development, and an agreed JellyChain1 network hasn't been formed yet, so this section is mainly just for fun.

- Minimum transation fee is 1000000000000 Jem.
- Minimum contract execution fee is 10000000 Jem.
I have been maintaining the project in my free time, if you like JellyChain1 and want to support, you can just leave a star and feel free to open issues and pull requests!
Thanks a lot!
JellyChain1 is 100% open-source, but if you are integrating its source code into your own project, it would be lovely if you credit the original JellyChain1, I would really appreciate it!
