At Kunstmaan we are hard at work to bring the first Blockchain based solutions into production. We chose Multichain to power our prototype demoed on the KBC Innovation fair in December 2015 and have continued to invest time and resources in getting this project production ready. We needed to interface with Multichain via its JsonRPC API and since there was no PHP library available we created one. It's this library that we release as our final open source contribution for 2015.
Getting a Docker Multichain cluster up and running
Before you can start developing a Multichain based solution you need a three server cluster up and running. Since Vagrant development solutions take up too much resources, we created Docker images.
The configuration for this cluster is defined by creating the following docker-compose.yml file:
version: '2' services: masternode: image: kunstmaan/master-multichain ports: - "7447:7447" - "8000:8000" environment: VIRTUAL_HOST: mulichain-master.docker VIRTUAL_PORT: 8000 explorer: image: kunstmaan/explorer-multichain depends_on: - masternode ports: - "2750:2750" environment: VIRTUAL_HOST: multichain-explorer.docker VIRTUAL_PORT: 2750 links: - masternode slavenode1: image: kunstmaan/node-multichain depends_on: - masternode links: - masternode slavenode2: image: kunstmaan/node-multichain depends_on: - masternode links: - masternode
You can then start this cluster by running docker-compose:
sudo docker-compose up
NOTE: these images are only for development use. They allow any node to connect and administer the cluster, and they open up the JsonRPC interface to everyone, everywhere!
UPDATE: We've added the Multichain Explorer image to inspect your blockchain.
Using the PHP Library
Now that we have a cluster up and running, we can start using the PHP library. Install the libray and it's dependencies into your project by running:
composer require kunstmaan/libphp-multichain
You now have the full power of the API at your disposal. A simple example is creating a new address. Ofcourse you need to change the URL...
$client = MultichainClient("http://<chainurl>:8000", 'multichainrpc', '79pgKQusiH3VDVpyzsM6e3kRz6gWNctAwgJvymG3iiuz', 3); $address = $client->setDebug(true)->getNewAddress();
The "tests" folder contains a whole lot of other examples, be sure to check them out!
