Cash for the
ghost economy

Grin is private, leaderless, and has no amounts on-chain. No CEO. No ICO. No premine. Just math, code, and a community that believes money should be free.

The philosophy

Money shouldn't leave footprints

In 2016, an anonymous developer posted a whitepaper to a Bitcoin forum under the name Tom Elvis Jedusor — Voldemort's name in French. The protocol was called MimbleWimble, the tongue-tying curse from Harry Potter. Then he vanished.

Two years later, Grin launched — no founders' reward, no company, no venture capital, no pre-sale. On launch day there were no coins to buy and no one to wire money to. Just a genesis block and a GitHub repository.

On Grin's blockchain, there are no addresses and no visible amounts. Every transaction is a cryptographic proof that value moved without recording how much or to whom. Blocks compress over time through cut-through — spent outputs vanish, and the entire chain stays lighter than most single-day Bitcoin traffic.

This is not a speculative asset. Grin emits one coin per second, forever — a constant issuance that dilutes toward zero inflation over decades without ever choking off miner rewards. It is electronic cash engineered to be spent.

Why it matters

Built different

Time-backed money

60 GRIN per minute — always, without exception, without anyone's permission. You cannot fake time or print more of it. The first monetary policy enforced by physics, not politics.

⚖️

Fair for everyone, forever

No halvings. No early-investor advantage. The same 60 GRIN per minute whether you discover it today or in 20 years. Everyone plays by identical terms.

👁️

Private by design, not by option

Amounts and parties are hidden in the cryptographic math of every transaction. Nobody can scan the blockchain to see your balance or trace who paid whom.

🏦

No custodian risk

No company in the middle — ever. Grin's supply is verified by open-source math on your own computer. There is no custodian who can be frozen or shut down.

🖨️

Protocol beats committees

Stablecoins lose value when governments print more. Bitcoin's security fades when minting stops. Grin's emission is hard-coded forever — no committee can change the rules, and miners always get paid.

🪶

A blockchain that stays small

Grin automatically removes spent data from the chain. After 7+ years live, the full history is ~5 GB pruned. Fast to sync, cheap to run a node at home.

🔍

Simple enough to verify yourself

No hidden allocations, no founder rewards, no complex tokenomics. The codebase is small enough for any engineer to read and audit end-to-end.

🌍

Built to outlast everything

Inflation falls smoothly every year — no halvings, no cliffs, no shocks. Anyone can fork the code, but not the history. Years of accumulated proof-of-work and community trust can't be copied. You can't fork time.
