JeChain 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 through its unfinished whitepaper.
First, be sure to have Nodejs installed on your machine.
Next, install all the needed packages:
npm install
If you haven't had your keys, goto ./utils, and type node keygen, it will generate a key pair for you.
Then, if you want to start a node, open the terminal, configure it first:
# PORT
PORT=Insert your port here
# Peers to connect when startup
PEERS=Address 1, address 2, address 3
# Set your address
MY_ADDRESS=ws://your.ip.and:port
# Set your private key
PRIVATE_KEY=your key
# Assign "true" if you want to set up a mining node, mining is disabled by default
ENABLE_MINING=true
# Assign "true" if you want to log out smart contracts' messages, this is disabled by default
ENABLE_LOGGING=true
# Start the node
node .On Windows, you can do the same with variables through set.
Mining a block:
mine();Broadcasting a transaction:
sendTransaction(yourTransaction);Requesting for a chain and its information:
requestChain("An address you trust");If you just want to set up a node that mines continuously (like most people would), use loopMine:
loopMine(optional_delay_time);You can manually connect to a node using connect:
connect("address");Note: All of the functions above are asynchronous functions.
Check ./src/blockchain.js, have a look at the genesis block, change the receiver address to your public address (because you should be the one who holds all the coins initially). Change the amount of coins if you want, it is set to 100000000000000 by default.
You shouldn't care about the minting address though, it can be anything you want.
Just forward port, drop your public IP + the port you forwarded in and you are set! If you don't know how to forward port, just search it up online, each model should have its own way to do port-forwarding.
Just host a bootstrap node and a node that mines continously, and then ask people to connect to the bootstrap node, and you have technically had a working blockchain network!
This feature is very new and is likely going to change in the future, but for now, you can read this document on creating smart contracts using a low-level language I have created called jelscript.
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.
Surely you can, but there might be some bugs or unexpected errors, so wait for 1.0 to have the best experience.
- Proof of stake.
- Sharding.
- EVM?
- RAM to ROM.
- Better APIs.
(Many features are already built, but are not pushed publicly due to testing).
I have been maintaining the project for free in my own free time, if you like the project and want to support, please leave a star on this project, feel free to open issues and pull requests!
You can kindly buy me a cup of coffee by sending me some ETH or Near too if you want ❤️, my addresses are 0x029B93211e7793759534452BDB1A74b58De22C9c and freakdev095.near.
Thanks!
JeChain is 100% open-source, but if you are using it for your own project, it would be lovely if you leave credit for me, I appreciate it!
