dAgora Chain

To spin up a validator node (using lotion) run:

node app.js

For a multiple remote nodes, run a validator and note its public IP address. Then run a peer client on a different node:

node app.js --host <HOST>

node app-peer.js --host <HOST>

(HOST defaults to localhost if not specified)

Scripts

To use a fresh chain, run npm run devMode beforehand.

The following command launches a lightweight client, sending a single value.

node scripts/cli-peer.js --host=<HOST> --port=<PORT> --data={ key: 'value', ... }

API Information

Access endpoints through HTTP. These are the HTTP endpoints (when the tx-server is running):

GET: http://localhost:<PORT>/state
POST: http://localhost:<PORT>/txs

Can be reached via Python's requests HTTP library:

>>> import json
>>> import requests

# GET Example
>>> r = requests.get("http://localhost:3000/state")
>>> json.loads(r.text)
{'MESSAGES': []}

# POST Example
>>> r = requests.post("http://127.0.0.1:3000/txs", json={'hello':'bye'})
>>> json.loads(r.text)
{'result': {'check_tx': {}, 'deliver_tx': {}, 'hash': '8FDBE289D77F3D918D7B49ED5315BA70F9FD6C95', 'height': '4556'}}

Be sure to follw the correct data format when posting. Data (transaction) format:

{
  KEY: ... ,
  CONTENT: ...
}

The relevant ABCI RPC endpoints are, though you shouldn't have to use them:

GET: http://<HOST>:<PORT>/abci_query
POST: http://<HOST>:<PORT>/broadcast_tx_commit?tx=<RAW_TX_HEX>

TODO

• Update to latest Lotionjs version
• Use commander with cli-peer.js
• Allow for multiple peers to be specified for app.js
• Validator autogen, selection, autoadd to genesis.json
• ✅ Additional tests for HTTP server
• ✅ Travis CI
• Autogen peer discovery
• Better structure for multi-node testing
• Use proper axios HTTP POST encoding in tx-server.js
