Etherchain Light

NOTE

This repo was converted from parity to geth and many features were dropped as they did not translate well.

Lightweight blockchain explorer for your private Ethereum chain

Etherchain Light is an Ethereum blockchain explorer built with NodeJS, Express and Geth. It does not require an external database and retrieves all information on the fly from a backend Ethereum node.

While there are several excellent Ethereum blockchain explorers available (etherscan, ether.camp and etherchain) they operate on a fixed subset of Ethereum networks, usually the mainnet and testnet. Currently there are no network agnostic blockchain explorers available. If you want to develop Dapps on a private testnet or would like to launch a private / consortium network, Etherchain Light will allow you to quickly explore such chains.

A demo instance connected to the Kovan Ethereum testnet is available at light.etherchain.org. An example of a verified contract source can be found at 0x0cf37d2d45427a1380db12c9b352d6f083143817. An example of a transaction where the corresponding Solidity function name and parameters have been identified can be found at 0x82da63f3d998415b748111e6f1d11051167fb995fdca990acd3cfd5a8b397c20

Usage notes

This blockchain explorer is intended for private Ethereum chains. As it does not have a dedicated database all data will be retrived on demand from a backend Geth node. Some of those calls are resource intensive (e.g. retrieval of the full tx list of an account) and do not scale well for accounts with a huge number of transactions. We currently develop the explorer using the Kovan testnet but it will work with every Geth compatible Ethereum network configuration. The explorer is still under heavy development, if you find any problems please create an issue or prepare a pull request.

Getting started

Supported OS: Ubuntu 16.04

Supported Ethereum backend nodes: Geth

1. Setup a nodejs & npm environment
2. Start geth_ipc using docker: cd passage-network-hapi-react/packages/passagex-ticketledger && ./scripts/docker_compose_local.sh geth_ipc
3. Clone this repository to your local machine. (Make sure to include --recursive in order to fetch the solc-bin git submodule)
4. We recommended that you delete everything in utils/solc-bin/bin EXCEPT the following, otherwise it will take WAY too long to deploy via docker.

• list.js
• list.json
• list.txt
• soljson-latest.js

6. Install all dependencies: npm install
7. Rename config.js.example into config.js and adjust the file to your local environment
8. Start the explore using docker: ./scripts/deploy_local.sh
9. Browse to http://localhost:3000
