[![NPM Version][npm-image]][npm-url]

With the smart-contracts, we are able to make exchanges with complex arbitrary rules. By looking at the interaction data, we hope to extract meaningful/valuable information that provide great assistance in decision-making process.

What is it?

- A platform that provides the ability to watch any smart-contract events, on any blockchain
- Only 3 modules: Watcher, Database, Visualiser
- Community-orientated: you can add support for your favourtite tools just by extending 3 base classes in each module

$3

This module allows you to extract data from smart-contract events. You only need to tell it:

- The address of the contract
- The blockrange (by blocknumber or by date)
- The data type you want to extract (you must be able to read smart-contract code)

$3

This module connects to your Graph DB and execute queries.

$3

This module executes MATCH queries to your Graph DB and display results.

Install

``bash
npm install argosjs
`

or

`bash
npm install https://github.com/zgorizzo69/EthGraphQL
`

Development

All customised libraries are put under vendor as git modules which are linked to other git repositories. If your

Usage

`javascript
const watcher = new EthereumWatcher(
contract.address,
contract.abi,
ProviderEnum.defaultProvider, {
username: config.database.neo4j.username,
password: config.database.neo4j.password,
bolt: config.database.neo4j.bolt,
enterpriseMode: config.database.neo4j.enterpriseMode,
driverConf: config.database.neo4j.driverConf,
model: config.contract.model
},
config.providers,
true,
config.contract.export

);
watcher.watchEvents("Transfer", fromDate, toDate).then(() => {
visualiser.refresh();
});
`

> Create an Visualiser instance (here NeoVis)

`javascript
const visualiser = new NeoVis(this.dbConstructor, "viz", config.datavis.neovis);

// Run community-detection algorithm (procedure) on DB
visualiser.detectCommunity(this.communityDetectionAlgorithm, {
label: 'Account',
relationship: 'TRANSFER',
writeProperty: "community"
});

// Run centrality algorithm (procedure);
visualiser.centrality(this.centralityAlgorithm, {
label: 'Account',
relationship: 'TRANSFER',
writeProperty: "size"
});

// Run pathfinding algorithm on DB
visualiser.pathfinding({
algo: PathFindingAlgorithmEnum.ShortestPath,
param: {}
});

// Display all nodes with LIMIT of 700 objects
visualiser.displayWithCypher({
query: "MATCH (n:Account)-[r:TRANSFER]->(m:Account) RETURN n,r,m"
}, 700);
``
