What is Vivuscoin?

A small, open-source proof-of-work coin from 2021, built on Bitcoin-derived code, with a paused chain, a published premine and a plan to restart. This page says what it is and, just as plainly, what it is not.

In one paragraph

Vivuscoin (ticker VVC) is an open-source proof-of-work cryptocurrency. Its software is a fork of Bitcoin Core, it uses the same SHA-256d hash as Bitcoin, and it runs its own chain with its own genesis block: no Bitcoin balance carries over. The chain launched in 2021. About 127.03 million VVC exist today, most of them created in a premine at launch and still held by the founder. VVC is not listed on any exchange and has no market price. The chain has been paused at block 24,092 since 22 September 2021 and is being restarted with a consensus upgrade called v1.1. The code is MIT-licensed at github.com/vivuscoin/vivuscoin.

How it works

Miners compete to find a block roughly every 240 seconds; the miner who finds one is paid 50 VVC, and that reward halves every 210,000 blocks. A block reward can be spent after 100 further blocks. Anyone can run a node: it connects to the two seed nodes on port 8168, downloads every block and checks each one against the rules itself. Addresses created by the Vivuscoin wallet start with A; older-style addresses start with 7 or 8, and native SegWit addresses start with vvc1.

Where the coins are

About 125.8 million of the 127.03 million VVC in existence were mined by the founder in the first 120 blocks, in 15 blocks that each paid 8,388,608 VVC.

The founder still holds about 119.2 million VVC, roughly 94 % of the supply; everyone else together holds about 7.8 million. Nothing was sold. The block heights, the rule that created the premine and what is being done about the concentration are all on the Supply & transparency page.

Why it is being restarted

The 2021 rules adjusted difficulty only once every 5,040 blocks, with the change clamped to a factor of four. That let someone push the difficulty up with a lot of hash power and then leave: the remaining miners could not find a block in any reasonable time, and the chain stopped at height 24,092 on 22 September 2021. The v1.1 upgrade fixes the cause rather than the symptom:

  • Difficulty adjusts every block, using a weighted average of the last 60 block times, so a change in hash power is absorbed in hours instead of weeks.
  • A stall recovers on its own. If no block arrives for 24 minutes, the required difficulty eases step by step within set limits, so the chain cannot freeze again.
  • History is harder to rewrite. Block timestamps may be at most 12 minutes in the future, reorganisations deeper than about 10 blocks are refused, and the existing checkpoints stay.

The upgrade activates at a set block height shortly after mining resumes, and wallets released before it must be upgraded before that height. What is done, what is in progress and what comes next is on the roadmap.

What it is not

Three things people ask about first. The honest answers are all “no” or “not yet”.

Not listed, no price

VVC is not traded on any exchange we know of and has no market price. Anyone quoting one is not us. The only ways to get VVC are to mine it or to register for the airdrop.

No ICO, no sale, ever

There was no ICO, pre-sale or token sale, and there is none now. The premine was mined by the founder at launch, not sold to anyone. Nobody is authorised to sell VVC on the project’s behalf.

Not finished

The wallets on offer are the 2021 v1.0.0.3 builds (Windows and an unsigned macOS image); v1.1 wallets ship with the restart. Until then the network status page and the block explorer are the live views of the chain.

Long-term mission

The mission behind the name

The 2021 whitepaper (PDF) is a mission paper, not a technical one. It describes a long-term research ambition: to simulate a human brain in a computer in full physical detail, so that life inside a computer becomes possible, and it proposes Vivuscoin, the “digital life token”, as the currency for computational resources in that future. That is the motivation behind the project. It is not a claim about what the coin does today, and the paper contains no supply or economics figures; every number on this site comes from the chain and its source code.
