Welcome to MultiChain Web Demo
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.
- 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).
The web demo does not yet support the following important functionality in the MultiChain API:
- Managing per-asset and per-stream permissions.
- Multisignature addresses and transactions.
- Adding metadata (or stream items) to permissions or asset transactions.
- Viewing an addresses' transactions.
- Subscribing to assets and viewing their transactions.
- Viewing a list of keys or publishers in a stream.
- Peer-to-peer node management.
- Message signing and verification.
- Blockchain upgrading.
- Working with the binary cache.
The MultiChain Web Demo is still under development, so please contact us if any of these things are crucial for your needs.
- A computer running web server software such as Apache.
- PHP 5.x or later with the
- MultiChain 1.0 alpha 26 or later, including MultiChain 2.0 alphas and betas.
Create and launch a MultiChain Blockchain
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
rpcallowip=[IP address of your web server]
Then start MultiChain again:
multichaind chain1 -daemon
Configure the Web Demo
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 demo directory, copy the
config-example.txt file to
cp config-example.txt config.txt
In the demo website directory, enter chain details in
default.name=Default # name to display in the web interface default.rpchost=127.0.0.1 # IP address of MultiChain node default.rpcport=12345 # usually default-rpc-port from params.dat default.rpcuser=multichainrpc # username for RPC from multichain.conf default.rpcpassword=mnBh8aHp4mun... # password for RPC from multichain.conf
Multiple chains are supported by the web demo by copying the same section again but with different prefixes before the period, for example:
another.name=... another.rpchost=... ...
Note that the
config.txt file is readable by users of your web demo installation, and contains your MultiChain API password, so you should never use this basic setup for a production system.
Launch the Web Demo
No additional configuration or setup is required. Based on where you installed the web demo, open the appropriate address in your web browser, and you are ready to go!
