Wallet Integration Guide

Developers and enterprises are integrating with the Blocknet Protocol to interoperate with onchain blockchain data and offchain data, APIs, and services to power a new genertion of microservice architectures. This page serves as technical documentation for integrating the Blocknet Protocol via the wallet to benefit from:

  • Trustless cross-chain token exchanges
  • Blockchain interoperability
  • Existing blockchain services
  • Existing blockchain user bases
  • Existing ecosystem and network effect

Installation

There are a few options for wallet installation:

For Docker: Here's a sample docker run command for Blocknet’s official Docker container:

docker run -d --name=block -p 41412:41412 --memory=1024m --cpus="2" --restart=unless-stopped -v=/LOCATION_OF_YOUR_DATA_DIR:/opt/blockchain/data blocknetdx/servicenode:latest blocknetd -daemon=0 -rpcuser=user1 -rpcpassword=blocknet123

In there you can see it's limiting the container to 2 CPUs and 1GB of RAM, specifying a custom data directory, and will restart automatically if it crashes.

To interact with the wallet:

sudo docker exec -it block blocknet-cli getinfo

Configuration

After installing the wallet, encrypt the wallet with password. By default the password is an empty string. The password can be updated through command line via the walletpassphrasechange command or with the GUI by selecting Settings > Encrypt Wallet or Settings > Change Passphrase in the the program menu.

Below are starter settings to be added to the blocknet.conf file:

datadir=/opt/blockchain/data  
dbcache=256                   
maxmempool=512

port=41412    # testnet: 41474
rpcport=41414 # testnet: 41419

listen=1                      
server=1                      
staking=0                     
maxconnections=25             
logtimestamps=1               
logips=1

rpcallowip=127.0.0.1          
rpcuser=                      
rpcpassword=                  
rpctimeout=15                 
rpcclienttimeout=15           
rpcthreads=8

Values will need to be specified for datadir, rpcuser, rpcpassword, rpcallowip, and rpcthreads. The rpcthreads should be set to 1 thread per blockchain that's being interacted with and should be set to rpcthreads=8 if interacting with 8 blockchains or less. The server should be isolated from public network with ports 41412/41474 open publically and ports 41414/41419 only open locally.

If your platform supports PoS staking, you may set staking=1. Otherwise, keep staking=0 or withdrawals may not function properly due to locked inputs.

All Bitcoin 0.8 configuration settings are valid with this wallet.

Integration

The standard RPC command list is the same as Bitcoin 0.8, with the addition of chain-specific XBridge and XRouter commands that can be found in the Blocknet API documentation.

Other

If using an address validator, the Blocknet addresses are standard Base58 with:

  • PUBKEY_ADDRESS = 26
  • SCRIPT_ADDRESS = 28
