Blockstore Client (Java)

This is a work-in-progress Java client library for Blockstore. Pull requests welcome.

This is modeled after a snapshot version of the Python Blockstore Client and should not be considered stable! This is able to communicate with a running instance of Blockstore, but it cannot currently query the DHT or other store of name records.

Not ready for production use! Not all commands work properly! Use at your own risk!

How to build

Just run

mvn clean install

Example use

package com.danubetech.blockstore.client;

public class Example {

	public static void main(String[] args) throws Exception {

		BlockstoreClient blockstoreClient = new BasicBlockstoreClient("localhost", Integer.valueOf(6264));
		DHTClient dhtClient = new BasicDHTMirrorClient("dht.blockstack.org", Integer.valueOf(6266));

		System.out.println(blockstoreClient.ping());
		System.out.println(blockstoreClient.getNameBlockchainRecord("christophera.id"));
		System.out.println(blockstoreClient.getNameCost("christophera.id"));
		System.out.println(blockstoreClient.getNamespaceCost("id"));
		System.out.println(blockstoreClient.getNamesInNamespace("id", 1000, 3));
		System.out.println(dhtClient.ping());
		System.out.println(dhtClient.get("dfe6e3f40a770c90fd8158f9c28c950631c4818b"));
	}
}
