Bitcoin Squared (BTCSQ), formerly codename "vBTC"

Overview

vBTC is the reference implementation for Bitcoin-based blockchains utilizing VeriBlock's Proof-of-Proof technology.

Below, you will find the steps needed to download and run the vBTC daemon.

Please note, all coins associated with this network are without value, and are for testing purposes only.

In the current implementation, we are using tVBK (testnet) to PoP mine (testnet) vBTC. vBTC inherits security from the VeriBlock TestNet, and VeriBlock TestNet inherits security from Bitcoin Testnet.

In order to PoP mine ALL 3 of the following are required to stay open and running:
1) NodeCore
2) vBitcoin
3) Altchain PoP Miner

Prerequisites:

It is recommended to have 4 cpu cores and 16GB of RAM to run all 3 applications. (NodeCore, APM, vBitcoin daemon)

Currently, VeriBlock TestNet requires a minimum of 6GB of space to sync. 10+ GB free space recommended.

64-bit Java

Tested using AdoptOpenJDK 8, 11, & 14 with HotSpot JVM. https://adoptopenjdk.net/

Download Packages for Linux

BTCSQ#Get_Package

Download Packages for Windows x64

BTCSQ#Get_Package

Package contains:

vBitcoin 0.4 Daemon

  • vbitcoin-qt.exe
  • vbitcoind.exe
  • vbitcoin-cli.exe
  • vbitcoin-tx.exe
  • vbitcoin-wallet.exe
  • vbitcoin.conf

vbitcoin.conf location

Located within the vBTC-release.0.4-<version>/data directory.

NodeCore 0.4.13-rc.1

Altchain PoP Miner 0.4.13-rc.1

Configuration and First Run

NodeCore

  1. Sync TestNet
    1. While you could sync from block 0, the fastest way is using the bootstrap downloader:
    2. Inside the nodecore folder, double click download_testnet_bootstrap.bat and it will download the latest TestNet bootstrap and place it in the nodecore/bin/testnet folder.
  2. Once the bootstrap-downloader has finished, you can close the window and double click bin/nodecore.bat to start NodeCore in testnet mode.

vBTC

Running vBitcoin QT Wallet

Double click the start-vbitcoin-qt.bat file to launch the QT Wallet using the data directory, instead of the default %appdata%\vBitcoin

vBitcoin Initial Start

Generate Reward Address

vBitcoin getnewaddress

APM (Altchain PoP Miner)

Edit application.conf

After unzipping the package, it can be found in altchain-pop-miner-0.4.12-<version>/bin/application.conf

Open application.conf, and update the payoutAddress to match the newly generated vBitcoin address to receive rewards.

NOTE: If you changed the vBitcoin RPC username or password, or if you are running a VeriBlock TestNet node on another machine you will want to update those fields as well.

Sample Config: 

miner {
  network: testnet
  feePerByte: 1000
  maxFee: 10000000
  api.port: 8080
  connectDirectlyTo: ["localhost"]
}
securityInheriting {
  vbtc: {
    // This can be set to [1,2,3,4]
    autoMineRounds: [4]
    payoutAddress: "tb1qdvkkx4r824wcgu92acwn88wll929jxkwey5gsd"
    pluginKey: btc
    id: 3860170
    name: "vBitcoin"
    host: "http://localhost:18332"
    // Uncomment if your vBTC daemon is auth protected
    auth: {
      username: "vbitcoin"
      password: "BETATeSt!"
    }
    payoutInterval: 150
    extraConfig: {
      daemonConnectionTimeout: 20000
    }
  }
}

Start the APM

Once you have edited the application.conf file, please start the APM by double clicking altchain-pop-miner.bat within the altchain-pop-miner-0.4.12-<version>/bin/ directory.

Funding APM Wallet

APM Initial Start

When the APM starts, you will see a line similar to Send funds to the tVBK wallet V4xwrouY6UNtBEC9V8fmWaibd4taqz
You will want to fund this wallet with VeriBlock TestNet coins. You can get testnet coins from a faucet, such as bitspill's community faucet at:
https://vbk.bitspill.net

Wait for SPV Synchronization

Once the wallet is funded you will need to wait for NodeCore to synchronize with the VeriBlock TestNet network if it is not already. 

2020-11-02 12:40:54 nc-poll    INFO  VeriBlockNetwork - SPV is not synchronized: 963230 blocks left (LocalHeight=30399 NetworkHeight=993629 InitialBlockDownload=false)
2020-11-02 12:40:54 nc-poll    INFO  AltchainPoPMiner - SPV is not ready

How To PoP Mine BTCSQ

Run getdebuginfo to check if APM is ready

This performs several checks, such that it can connect to both NodeCore and vBTC daemons, and has a VBK balance.

Once vBitcoin and NodeCore have synchronized, and you have funded your tVBK wallet in the APM, you can type 'mine vbtc' to submit a PoP transaction.

You may need to wait for wallet funding:

How To PoW Mine BTCSQ

One can proof-of-work mine via the stratum pool.

There is a stratum implementation and running pool.

Note: This pool is setup for CPU mining only, and as such, difficulty of shares is too low for GPU or ASIC mining.

CPU Miner Binaries:

Linux: https://mirror1.veriblock.org/btcsq-minerd

Windows: https://mirror1.veriblock.org/btcsq-minerd.exe

CPU Miner Start String Examples:

Linux: ./btcsq-minerd -o 'stratum+tcp://testnet.pool.vbtc.veriblock.org:3333' -u <legacy_address> -p x -a sha256d

Windows: btcsq-minerd.exe -o stratum+tcp://testnet.pool.vbtc.veriblock.org:3333 -u <legacy_address> -p x -a sha256d

To use this pool you will need to generate a legacy address using the command: vbitcoin-cli getnewaddress "mining" legacy

Pool: https://testnet.pool.vbtc.veriblock.org/

How to upgrade

If you are already pop mining vBTC, then upgrading is relatively easy.

Get latest package. This will have 3 separate applications:

  • APM
  • NodeCore
  • vBTC daemon

Each part can be upgraded as needed. For example you may only want to upgrade to the new APM, and not change NC or vBTC.

Upgrade APM

  1. Shut down old APM
  2. Copy these files to new APM /bin folder:
    1. application.conf
    2. vbk-testnet.wallet --> this has your tVBK for sending altchain pop transactions
  3. Start new APM

Upgrade vBTC Daemon

  1. Shut down old vBTC
  2. Start new vBTC

Note: The new vBTC should have the same vbitcoin.conf and blockchain as before, therefore no need to update the conf or blockchain.

Note: It may take some time to resync the network. (There are known issues to optimize this).

How To Compile BTCSQ

Please refer to https://github.com/VeriBlock/vbk-ri-btc/blob/release/0.4/doc/build-unix.md for manually building the application.
