Overview
The NodeCore package has two main folders:
- bin - The scripts and data files. This page will discuss the files here.
- lib - All the jar files. This could be about 50 files and 30MB.
NodeCore starts with two script files:
- nodecore --> execute on linux/mac
- nodecore.bat --> execute on windows
Running NodeCore creates several additional local files. These store data (like the blockchain, wallet, pool, etc...) and configuration.
Note that NodeCore has a startup "-d" parameter to write the data files to a specific folder:
#Linux Example ./nodecore -d ~/data/ #Windows Example nodecore.bat -d E:\Data
By File Type
Log
Standard log files, generated by slf4j.
Examples:
- veriblock.nodecore.log
- veriblock.nodecore-2018-04-04.0.log
- veriblock.nodecore-error.log
Config
Plaintext files, user can modify these config values.
Example:
- nodecore.properties
Data
Contains data written by NodeCore. These are SQLite files.
The nodecore.dat file can be viewed with a SQLite browser: http://sqlitebrowser.org, however it is an internal file intended to be written to solely by the NodeCore instance.
The others have their own special formats and are not SQLite databases.
Examples:
- nodecore.dat
- wallet.dat
- walletconfig.dat
- poolwallet.dat
- poolwalletconfig.dat
Other
- tcache.csh - A cache file of nodecore.dat such that NodeCore can reload the blockchain much faster upon restart.
- poolshares.txt - A plaintext file that stores the history of submitted shares to the pool operated by the local NodeCore instance (will not be present if pool has never been run).
By Folder
blocks
This folder will contain a set of subfolders with numerical values, and in each of these subfolders there will be a numerical .dat file, those files contains the blocks' biggest data (~1 file per day and ~1 subfolder per year).
By File
nodecore.dat
The blockchain data itself, as well as additional operational information (blacklisting IPs, caching broadcast blocks, etc...). This is the distributed ledger shared among all nodes.
To view the public blockchain, check out the dashboard: https://testnet.explore.veriblock.org
nodecore.properties
See: nodecore.properties for exact reference on each property value.
If this file does not exist, then NodeCore will create it.
If this file is changed, then NodeCore may need to be restarted to use the new value.
veriblock.nodecore.log
Rolling log file. Older logs will have the date in them, such as veriblock.nodecore-2018-04-04.0.log.
veriblock.nodecore.log is always the most recent log.
veriblock.nodecore-error.log
Contains just errors, ideally this is always empty.
The results of the pool. See: HowTo_run_and_connect_to_PoW_Miner_pool
ROUND,1 VGdQFeskH63Wk8Xk3bJM8hLDG8CLV1,1 ROUND,2 VGdQFeskH63Wk8Xk3bJM8hLDG8CLV1,1
poolwallet.dat
The dedicated wallet for the pool. This is an internal file.
poolwalletbackup.dat
A backup file for the pool. This is an internal file.
poolwalletconfig.dat
A configuration file for the pool's wallet. This is an internal file.
tcache.csh
A cache file for the blockchain, built upon first load, such that subsequent restarts of NodeCore are much faster.
wallet.dat
Your wallet, with addresses and balances. The NodeCore_CommandLine provides several wallet-features:
- getbalance - see the available balances
- backupwallet - copies the wallet.dat (and related files) to a specific backup location.
walletconfig.dat
A configuration file for the wallet. This is an internal file.
By Function
NodeCore Executable (affects all)
Examples:
- nodecore.properties
- veriblock.nodecore.log
- veriblock.nodecore-error.log
Blocks
Examples:
- nodecore.dat
- tcache.csh
- 000.dat, 001.dat, 002.dat, etc
Wallet
The wallet stores a list of public-private keypairs. The wallet does not contain any information regarding transactions or balances.
To backup the wallet, one can run the backupwallet command from NodeCore_CommandLine, and this would copy their files to the given location.
Examples:
- wallet.dat
- walletconfig.dat
Pool
Examples:
- poolshares.txt
- poolwallet.dat
- poolwalletbackup.dat
- poolwalletconfig.dat
Other Notes
TestNet subfolder
Under the bin folder, there is a separate testnet subfolder for various data files for TestNet.
