Grin was started with as fair of a launch as possible for what's under our control. We did this for good reason: we believe in Grin's mission to enable private money for everyone and open access to it.

What is Mimblewimble?

grin --explain mimblewimble
Name: Mimblewimble
Type: Blockchain protocol
Origin: Anonymous — "Tom Elvis Jedusor" (2016)
Paper: MimbleWimble Origin (2016) ↗
Impl: "Ignotus Peverell" → Grin (2019)
Status: ACTIVE — Mainnet since Jan 15, 2019

# Core properties:
✓ No addresses — transactions are interactive
✓ Confidential Transactions (CT) — amounts hidden
✓ Transaction cut-through — chain data shrinks
✓ No scripts — minimal attack surface
✓ Linear emission — 60 GRIN/min, same rate for centuries
⬡
Decentralized
No foundation, no investors, no pre-mine. Community governed from day one.
🔒
Privacy First
Amounts and addresses are cryptographically hidden. Transactions are indistinguishable.
⚡
Scalable Chain
Transaction cut-through removes historical data. Blockchain stays lean forever (~5 GB pruned).
◆
Fair Launch
No ICO, no airdrop, no venture backing. 60 GRIN per minute — the same forever.
// 02 — COMPARISON

Why Grin Over Other Assets?

⏱
Time-Backed Monetary Policy
60 GRIN minted every 60 seconds — forever. No halving shock, no supply cliff. Early adopters and newcomers receive equal terms. Time itself is the backing mechanism: one minute of network existence equals 60 new coins, making Grin's supply as predictable as a clock.
👁
True On-Chain Privacy
No addresses, no amounts are ever written to the blockchain. Mimblewimble's Confidential Transactions and transaction cut-through guarantee that on-chain data reveals nothing about senders, receivers, or values — enforced by cryptography, not by policy.
⚖
vs. Gold — Unverifiable in Digital Form
Physical gold cannot be audited at scale in digital custody. Tokenized gold requires trusted custodians who can be subpoenaed, audited, or compromised. Grin's supply is mathematically verifiable by anyone running a full node — no custodian required, ever.
$
vs. USD-Pegged Assets — Inflationary by Design
Fiat-backed stablecoins import monetary policy risk by definition. When central banks expand money supply, stablecoin holders absorb the dilution. Grin's emission rate is fixed in protocol code — no committee, no decree can change it.
₿
vs. Bitcoin — Finite Supply, Uncertain Future
Bitcoin's 21M hard cap means that once the last coin is mined, miner incentives rely entirely on transaction fees. Whether that model sustains security at scale remains an open economic question. Grin's perpetual tail emission removes this uncertainty — miners are always compensated proportionally.
🪶
Minimal Blockchain Footprint
After 7+ years of live transactions, Grin's pruned node weighs ~5 GB and the full archive ~17 GB. Transaction cut-through mathematically eliminates spent outputs so the chain does not accumulate transaction history. Lightweight by protocol, not by compromise.
∞
Century-Scale Emission — Designed for Generations
Grin's linear supply curve means the inflation rate asymptotically approaches zero over time — without hard stops or abrupt halvings. Future participants decades from now still receive a fair on-ramp to a network that front-loaded no wealth to early insiders.
🔓
Auditable, Simple, Open-Source
Grin's protocol is deliberately minimal. No proprietary components, no hidden supply curves, no special pre-allocated addresses. The codebase is small enough for a competent engineer to read and verify independently. Full auditability is a design goal, not a marketing claim.
⟳
Grin Is Unreplicable — Time Cannot Be Copied
Any fork resets the clock. Grin's years of accumulated proof-of-work, protocol maturity, and community trust are a function of elapsed time — fundamentally non-fungible at the chain level. You cannot copy "our time has been spent." That makes Grin genuinely unique.
// 03 — PROCESS

How Grin Works

01
$ grin tx --build
Transactions are built interactively between sender and receiver. No public addresses — wallets exchange a "slate" to construct a joint signature.
02
$ grin tx --encrypt-amounts
Amounts are encrypted using Confidential Transactions (Pedersen commitments). Only sender and receiver know the value transferred.
03
$ grin block --merge-txns
Multiple transactions within a block are merged into one via CoinJoin-style aggregation, making individual transactions harder to trace.
04
$ grin chain --cut-through
Spent outputs are removed from the chain entirely. The blockchain never grows with the transaction history — only the current UTXO set matters.
