EarthCoin-API

Full EarthCoin node with API based on bitpay/bitcore

Pre-requirements:

• MongoDB - https://docs.mongodb.com/manual/installation/
• Nodejs - https://nodejs.org/en/

Install & run:

git clone https://github.com/Sandokaaan/EarthCoin-API.git 
cd EarthCoin-API
start.sh &

Upgrade from an older pre-release version

If an erlier version of this code was run on your machine, the old database data have to be deleted manually by commands:

mongo
use dbEarthCoin
db.dropDatabase()
exit

Configuration

Some parameters, such as port number or preffered network nodes can be set in the file 'config.json'

API interface:

http://<YOUR_SERVER_ADDRESS>:3000/

This code is under development, some functions are not implemented, yet.

What does work?

• Sync from a network. Legacy EarthCoin daemon is not required. Under test conditions the node got full sync from a scratch within a hour.
• API can show any block on hash or index query.
• API can show any transaction and address balance.
• API function for unspent balance (UTXO). Addresses with more that CONFIG.dbLimit are not shown because of complexity of the calculation (may take up to 30 seconds).
• API function 'txbyaddr' on demand of a dev-team member.
• Block Explorer - simple HTML version without graphics and client-side scripts

To do list:

• Configuration is hardcoded in the javascript for now. Need to be moved to a .json file to easier setup.
• Detection of forks/orphans blocks - it is still buggy, from time to time lost the sync
• Indexing of transactions and API functions for read transactions info.
• Implement functions for both-way comunication. For now the node not answer to other nodes queries.
• Automatic selection of the best node for data download, eg. based on a ping delay.
• Optimization of the code for multi-node queries, now the code select one network node to request all block data.
• Standardize modular design of the code, add NPM installer.
• Split API and SYNC into two independend proccesses. Some API calls can break the sync.
• A better design of transaction indexing --> speed-up calculation of a big wallet balance.
• A request for balance of an address with a huge number of transactions can cause DoS. Only small wallets will be enabled without API key.
• A database structure for a quick calculation of unspent balance for mining addresses (about 10-50k coinbase transactions) ???
