SPV is currently in BETA, and is not part of an official release.

Assume there are bugs.

Overview

NodeCore SPV (Simple Payment Verification) is a light wallet that allows a user to see their balance and send VBK without downloading, syncing, and running a full node.

SPV can run as a separate process, and the NC_CLI can connect to an SPV node.

For convenience, a separate package is created by modifying the NC_CLI package that allows one to directly run the SPV.

How to Install

Download BETA from here:

Tested on OpenJDK 8, 11, 14, for Windows and Ubuntu Linux

How to Run SPV

  1. Unzip the package to its own folder
  2. Run "veriblock-spv.bat" (Windows) or "veriblock-spv" (Linux/Mac)
  3. Wait for the SPV to sync (generally 10 minutes for every 1 million blocks; time will vary)

This means SPV is ready:

SPV is ready. Current blockchain height: 1004200

Run "help" to see available commands (see NodeCore_CommandLine for detail on each command):

Commands:

    disconnect
    importwallet
    importprivatekey
    encryptWallet
    getnewaddress
    exit
    lockWallet
    unlockWallet
    getstateinfo
    getbalance
    backupwallet
    send
    decryptWallet

For example:

send <amount> <destinationAddress>

}

File Structure

Running the SPV will create a "data" folder, as well as log and wallet files.

Known Issues

This is a BETA, and there are several known issues.

Ensure that a NodeCore full node is not already running, as it will interfere with NC_CLI connecting to SPV.

SPV does not show locked coins (from MainNet launch). If you have a locked-coin balance, SPV will still show as zero.

Running importwallet may take a few minutes to sync the new wallet.
