Plasma-ish

This is an example implementation of side chain inspired by the technique called plasma. You can find more detail on my blog.

Features

1. get transactions from child net and generate merkle root hash and submit the data to parent net
2. check proof on parent net

How to try

In production environment, parent net is supposed to be the Ethereum main net and child net is supposed to be a private net. But for experiment, you can use any Ethereum network to any roll.
For example, the Ropsten testnet for childnet and a private net for parentnet. It's convenient because there are already enough transactions in the Ropsten testnet.

Install

git clone https://github.com/Sotuu/plasma-ish.git
cd plasma-ish
npm install

deploy 2 contracts.

deploy PlasmaParent_submitonly contract on parent net deploy PlasmaChild_submitonly contract on child net

create settings.js

cp settings_example.js settings.js

submit merkle root hash

test_submit command get tranasctions from child net to create merkle root hash and sumbit it.

npm run test_submit

check proof

You can put raw transaction and plasma block number which you can see on console.log of test_submit in settings.js

npm run test_proof

Todos

1. Transferring ERC20 between parent and child network.
2. Experiment for grand child network
