Changes / extensions to the original version:
- Changed configuration method to eliminate security risks: Configuration is now a php file.
- More details displayed for the connected nodes.
- Menubar optimized.
- Integration of a (simple) Block Explorer.
- Integrated mc-info (query infos for monitoring using /mc-info.php)
MultiChain Web Demo is a simple web interface for MultiChain blockchains, written in PHP.

This software uses PHP to provide a web front-end for a MultiChain blockchain node.
It currently supports the following features:
- Viewing the node's overall status.
- Creating addresses and giving them real names (names are visible to all nodes).
- Changing global permissions for addresses.
- Issuing assets, including custom fields and uploading a file.
- Updating assets, including issuing more units and updating custom fields and file.
- Viewing issued assets, including the full history of fields and files.
- Sending assets from one address to another.
- (Creating, decoding and accepting offers for exchanges of assets. <= disabled in this fork)
- Creating streams.
- Publishing items to streams, as JSON or text or an uploaded file.
- Viewing stream items, including listing by key or publisher and downloading files.
- (Writing, testing and approving Smart Filters (both transaction and stream filters). <= disabled in this fork)
- A (simple) block explorer to display a list of blocks and details (transactions ...) of each block. <= NEW in this fork
- A computer running web server software such as Apache.
- PHP 5.x or later with the
curlandJSONextensions. - MultiChain 2.0 or later.
If you do not yet have a chain to work with, Download MultiChain to install MultiChain and create a chain named chain1 as follows:
multichain-util create chain1
multichaind chain1 -daemon
If your web server is running on the same computer as multichaind, you can skip the rest of this section. Otherwise:
multichain-cli chain1 stop
Then add this to ~/.multichain/chain1/multichain.conf:
rpcallowip=[IP address of your web server]
Then start MultiChain again:
multichaind chain1 -daemon
This section assumes your blockchain is named chain1 and you are running the node and web server on a Unix variant such as Linux. If not, please substitute accordingly.
Make your life easy for the next step by running these on the node's server:
cat ~/.multichain/chain1/multichain.conf
grep rpc-port ~/.multichain/chain1/params.dat
In the web gui directory, copy the config-example.php file to config.php:
cp config-example.php config.php
Enter optional configuration and details for one (or more) chains in config.php e.g.:
// optional configuration for monitoring script "mc-info"
$config->serverName = 'blockchains.example.io';
$config->serverOwner = 'Example Ltd.';
$config->externalIP = '11.22.33.44';
$chains = array();
// configuration for a Multichain blockchain
$chain = new stdClass;
$chain->name='chain1'; // name to display in the web interface
$chain->rpchost='192.168.1.23'; // IP address of MultiChain node
$chain->rpcport=1234; // default-rpc-port from params.dat
$chain->rpcuser='multichainrpc'; // username for RPC from multichain.conf
$chain->rpcpassword='---password---'; // password for RPC from multichain.conf
$chains[] = $chain;
No additional configuration or setup is required. Based on where you installed the web gui, open the appropriate address in your web browser, and you are ready to go!
The script "mc-info.php" collects different information about the configured nodes and builds a JSON response, which can be used e.g. for monitoring purposes.
