Vochain Explorer

[p4u]

Implement a block explorer for the Tendermint based Vocdoni blockchain (vochain).

There is an existing old tendermint block explorer that might be useful to look at, the code can be found here.

In order to test it locally a testsuit docker-compose can be started as shown in the developer starting guide.

The file ./src/store/modules/blockchain.js of the vochain-explorer should be modified as follows:

const state = {
  rpc: "http://127.0.0.1:26681",

Then the explorer can be compiled and executed:

yarn
yarn serve

The tendermint RPC API should be used for basic blockchain information (validators, number of blocks, etc).

And the Gateway API on websockets port 9090 should be used for specific Vocdoni information (such as getProcessList, getEnvelopeStatus, etc)

The block explorer should allow:

• [ ] search tx/block by hash
• [ ] see pending and already valid txs
• [ ] Clearly distinguish between different kinds of txs (by colour/name ?)
• [ ] see current blockchain height, hash, validators, block number, appVersion, Max block size, chainID (tendermint API)
• [ ] see the raw/json transactions contained inside a block (tendermint API)
• [ ] see voting process, entities, votes and results (Gateway API) --> Extended version (near future)

Basic information regarding the Vochain can be found here (OUTDATED but mostly valid) .

A pure-go, nice framework, that could be used is https://github.com/gopherjs/vecty

• Go UI : https://github.com/go-graphics/go-gui-projects
• Gioui: https://gioui.org (probably the most modern framework, but maybe not yet ready for Webassembly)
• A nice explorer: https://blockscout.com/poa/core/
