V4Coin: A Peer-to-Peer Hooked Cash System

Bitcoin's monetary policy, rebuilt as a Uniswap v4 hook. A fixed 21,000,000 supply and a halving block subsidy — no mining rigs. You mine V4C simply by staking V4C, and the subsidy halves every time the minted supply hits a milestone.

How mining works

Your stake is your hash rate

There are no ASICs and no proof-of-work here. You stake V4C and the protocol emits a per-second block subsidy, split — pro-rata — among every staker. Stake more, mine more. On the Uniswap v4 pool, every swap is a "block" that ticks the mining clock.

STEP 01

Stake your V4C

Deposit V4C into the staking hook. Your share of the total staked is your share of the network's "hash rate" — no lock-up, withdraw anytime.

STEP 02

The hook mines for you

Every second the block subsidy accrues to your stake. Each swap on the V4C/ETH v4 pool advances the clock, so rewards stay fresh with on-chain activity.

STEP 03

Harvest & watch the halving

Claim freshly-minted V4C anytime with harvest(). Every time minted supply crosses a milestone, the subsidy halves — until all 21M are mined.

Tokenomics

The same curve that made Bitcoin scarce

Each halving is triggered when the minted supply crosses a milestone — 10.5M, then 15.75M, then 18.375M — with every era minting exactly half of the last. The infinite sum converges precisely to the 21,000,000 cap.

Roadmap

From genesis block to frozen policy

PHASE 0Complete

Genesis & contracts

V4Coin (V4C) and the halving hook deployed and audited. 21M cap and emission math locked into immutable code.

PHASE 1In progress

Offering & staking pool

The 10M launch offering opens and the V4C/ETH pool goes live on Uniswap v4 with the hook attached. Staking-based mining opens to everyone — no whitelist.

PHASE 2Next

Miner dashboard & leaderboard

Live position tracking, harvest UI, and a hash-rate leaderboard ranking the network's biggest miners.

PHASE 3Planned

Renounce & decentralize

Mint authority handed to the hook and the owner key renounced — monetary policy frozen forever, exactly like Bitcoin.

FAQ

Questions before you mine

How is this a "Bitcoin fork" if it's an ERC-20? +
It forks Bitcoin's monetary policy, not its codebase: a 21,000,000 hard cap and a block subsidy that halves as supply is minted. Distribution is fixed — a 10M launch offering at genesis, then 11M mined by stakers. Instead of proof-of-work securing emission, stakers earn it — optionally driven by a Uniswap v4 hook.
What exactly do I have to do to mine? +
Stake V4C in the staking hook. It tracks your share of the total staked and accrues the per-second subsidy to you. Call harvest() whenever you want to mint the V4C you've earned. Unstake and you simply stop mining — your principal comes back with it.
What is the halving? +
Halving is triggered by supply, not the clock. Each time minted supply crosses a milestone — C/2 (10.5M), then 3C/4 (15.75M), then 7C/8 (18.375M) — the subsidy is cut in half. Every era mints exactly half of the previous, so the total converges to exactly 21M. Because 10M is already in circulation, the first halving (at 10.5M) arrives quickly; after that each era spans roughly four years, like Bitcoin.
Is there a team allocation or presale? +
10M INITIAL_SUPPLY is minted to the owner at deploy for the launch offering / LP seed. The remaining 11M is mined by stakers on the halving schedule. There is no separate presale of emitted supply.
Can the supply ever exceed 21 million? +
No. The cap is enforced in the token's mine() function and the hook clamps every emission to the remaining supply. Once minting authority is renounced, no address can ever create new coins.
