Overview
NodeCore is the service that runs the VBK blockchain. It is written in Java, and runs on Windows, Linux, and mac.
Steps
Unzip the package:
| Windows | Mac and Linux |
|---|---|
| Unzip the nodecore-*.zip file In the bin folder, then run nodecore.bat | Unzip to your preferred directory, then run nodecore.
Note: On Linux & Mac systems, you may need to make the nodecore shell script executable by running the following command: chmod a+x nodecore |
When you first run NodeCore, it will create several other files in a new testnet folder (nodecore.properties, veriblock.nodecore.log, nodecore.dat, etc...), and load the existing blockchain.
NodeCore may take several minutes to load all the blocks in the blockchain. See the highest block at https://TestNet.Explore.Veriblock.org. This shows the number of blocks your local instance must load. NodeCore will create a cache file such that when you restart it they will load faster next time.
FAQ
How do I keep my wallet when upgrading to a new version of NodeCore?
The easiest way to upgrade is to copy the testnet folder (which contains the wallet, blockchain, and many files listed here: NodeCore_File_Structure) to the new version.
Troubleshooting
Java out-of-memory
Modify the start file (nodecore.bat for windows, nodecore for linux) to increase the memory limit. Pass in a value, such as "1024 MB" into the DEFAULT_JVM_OPTS variable:
DEFAULT_JVM_OPTS=-Xmx1024m
