Generic Block Explorer for Exonum-based blockchains

This guide will show you how to use this block explorer with Exonum-based blockchains.

Prerequisites

1. Rust compiler,
2. Node.js,
3. An extension for your web-browser allowing to change CORS headers. This is required because we are going to make cross-domain requests. As of version 0.3, Exonum has no built-in mechanisms to configure Cross-Origin policy. Yo may use, for example, Moesif Origin & CORS Changer for Chrome.

An Exonum-based blockchain application

For the purpose of this example we are going to use a cryptocurrency built using Exonum.

1. Get and run the cryptocurrency example:

git clone https://github.com/exonum/cryptocurrency.git
cd ./cryptocurrency
cargo run

2. Go to the ./example,
3. Send some transactions to the server:

curl -H "Content-Type: application/json" -X POST -d @create-wallet-1.json http://127.0.0.1:8000/api/services/cryptocurrency/v1/wallets

curl -H "Content-Type: application/json" -X POST -d @create-wallet-2.json http://127.0.0.1:8000/api/services/cryptocurrency/v1/wallets

curl -H "Content-Type: application/json" -X POST -d @transfer-funds.json http://127.0.0.1:8000/api/services/cryptocurrency/v1/wallets/transfer

You might want to pause a little between sending the transactions for them to end up in different blocks.

Block explorer

1. Get and run the block explorer:

git clone https://github.com/nedap/exonum-block-explorer.git
cd ./exonum-block-explorer
npm install
npm start

2. Navigate to localhost:8080,
3. IMPORTANT Enable CORS changer (see Prerequisites, item 3),
4. Refresh the page you must be able to see recent blocks and recent transactions,
5. Explore!
6. IMPORTANT Do disable CORS changer after you finished exploring.
