Vivuscoin wallets

Vivuscoin Core is the reference wallet and full node, and the only wallet there is. The current release is v1.0.0.3 from 2021 for Windows and macOS, built from the MIT-licensed source on GitHub. Verify the checksum before you install.

Go to downloads Release notes on GitHub

v1.1 wallets are coming and will replace v1.0.0.3.

The v1.1 release restarts the chain with new difficulty rules. Every wallet must be upgraded before the activation height, which is not set yet and will be announced with the release. Wallets that are not upgraded stop following the chain at that height. Your keys, addresses and wallet.dat carry over unchanged. Follow the roadmap.

GUI build · 2021 · legacy

The 2021 vivuscoin-qt build is kept for reference only: it does not run on current distributions. Build from source today, or wait for v1.1, which ships Linux binaries built to run on current Ubuntu LTS.

Verify your download

Compare the SHA-256 of the file you downloaded with the value below. If they differ, delete the file and download it again from GitHub; do not install it. These values were computed from the v1.0.0.3 assets on the GitHub release page. v1.1 will ship a SHA256SUMS file alongside its binaries.

How to compute the checksum

Windows · Command Prompt or PowerShell 
certutil -hashfile %USERPROFILE%\Downloads\vivuscoin-1.0.0.3-win64-setup.exe SHA256
macOS · Terminal 
shasum -a 256 ~/Downloads/Vivuscoin-Core.dmg
Linux · shell 
sha256sum vivuscoin-1.0.0.3-win64-setup.exe

A checksum proves the file is the one published on GitHub; it does not make the build signed. The macOS build has never been signed or notarized, which is why Gatekeeper asks you to confirm.

What is in v1.1

v1.1 is a consensus upgrade built to restart the chain and keep it running. Same genesis, same network, same coins. In plain words it changes four things:

  • Difficulty adjusts every block (LWMA-1 over a 60-block window) instead of every 5,040 blocks, so difficulty follows the real hash rate closely.
  • A bounded emergency rule lowers difficulty when no block arrives for a long time, so a stall like the one in 2021 recovers within hours rather than never.
  • Tighter block-timestamp limits: a block may be at most 12 minutes in the future, not 2 hours, which removes the room for timestamp games.
  • Deep reorganisations are refused (deeper than about 10 blocks), and the existing checkpoints are kept, so balances up to 24,092 cannot be rewritten.

Upgrade before the activation height.

v1.1 activates at a set block height shortly after mining resumes. The height is published with the release; it is not set yet. Until then v1.0.0.3 is the release to run.

The restart plan, step by step

Third-party wallets

None. Vivuscoin Core is the only wallet. Hardware wallets, mobile wallets, browser wallets and exchanges do not support VVC, and VVC is not listed on any exchange. If a third-party app or website claims to hold or trade VVC, it is not affiliated with this project; treat it as a scam until proven otherwise, and never enter your keys into it.

Backing up and restoring

Your coins are controlled by the keys in wallet.dat, not by the application. Keep your keys offline: encrypt the wallet, back the file up to media that is not connected to the internet, and keep the backup in more than one place. The project never asks for your keys, your passphrase or your wallet file.

Where wallet.dat lives

SystemData directory
Windows%APPDATA%\Vivuscoin\
macOS~/Library/Application Support/Vivuscoin/
Linux~/.vivuscoin/

The same directory holds vivuscoin.conf (settings such as addnode=) and the downloaded chain, which you never need to back up.

Backup

  1. Settings → Encrypt Wallet. Choose a passphrase you can store safely; there is no recovery if it is lost.
  2. File → Backup Wallet, or copy wallet.dat while the wallet is closed. Do it again after you create new addresses.
  3. Store the copy offline, for example on two USB drives kept apart.

Restore

  1. Install Vivuscoin Core and let it sync once, then quit it.
  2. Replace wallet.dat in the data directory with your backup and start the wallet. If a balance is missing, start the wallet once with the -rescan option.

Single keys

In the debug console, dumpprivkey <address> prints the private key of one address and importprivkey <key> imports one. An unlocked wallet is needed (walletpassphrase). Treat a printed key exactly like the wallet file: anyone who sees it can spend from that address.

Wallet FAQ

Why does the wallet show 24,092 and stop?

Because that is the last block. The chain has been paused at height 24,092 since 2021-09-22, so a wallet showing 24,092 is fully synced. Transactions confirm again once blocks are produced after the v1.1 restart; see the roadmap.

Is the Mac build signed?

No. The 2021 .dmg is unsigned and not notarized, so macOS refuses to open it on double-click. Verify the checksum, then right-click the app and choose Open the first time. Whether v1.1 ships signed depends on a dedicated developer identity being set up; if it is not, v1.1 will be unsigned too and the same steps apply.

Can I run a node without the GUI?

Yes: vivuscoind and vivuscoin-cli are the headless daemon and its command-line client, built from the same source. Today that means building from source; v1.1 ships them as Linux binaries. Ports, seed nodes and build steps are on the Developers page.
