Grin (GRIN)

Grin ranks #194 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1473: 1279 of the 1472 assets ahead of it are not native coins but tokens or claims. A token is issued on a host blockchain rather than running its own; a claim stands for an asset already counted. Of the 1706 non-native assets CoinSpectrum lists above it by market cap, about 75% are tokens, 20% are claims on other assets and 6% are memecoins.

Protocol level privacy (Keys not tied to an identity · Whitepaper §10)✓Mimblewimble outputs are Pedersen commitments controlled by blinding factors users generate; there are no accounts or identities.

Network privacy (Origin hidden by default)✓Grin node relays transactions through Dandelion stem/fluff by default (stem_probability 90, always_stem_our_txs in the default config).
Hidden amounts (Amounts confidential)✓Mimblewimble Pedersen commitments with range proofs hide every amount since launch (2019).
Hidden parties (Sender and receiver hidden)✗Outputs carry no addresses, but there are no ring signatures or ZK proofs hiding which outputs a transaction spends, so the brief's two-part test is not met.
Programmability (tokens, contracts, 5 checks)00 of 9 points source
Token issuance0No token issuance on the chain itself
Smart contracts0Mimblewimble has no script; the only spending conditions are signatures and kernel lock heights (fixed kernel types).
Multisig and time locks (Without a third party)✗Height-locked and relative (NRD) kernels give time locks, but multiparty outputs are n-of-n only; no m-of-n threshold spending.
Atomic swaps (With other chains)✗No hash locks; Grin's docs describe a scriptless atomic-swap construction, but no working implementation in the reference wallet was found.
Native exchange (Built into the protocol)✗No exchange in the protocol.
Cross-chain messaging (Verified by the chain itself)✗No cross-chain feature in the protocol.

Twenty criteria, weighted equally. The Cryptocurrency Standards have five sections: sound money (six qualities: scarcity, durability, fungibility, portability, divisibility, verifiability), scalability (four measures and three features), security (miner pay and seven checks), decentralisation (censorship resistance, no central team, who can mint, nodes, holders, premine, fundraising and developer share) and privacy (five checks); programmability (token issuance, smart contracts and five checks) follows them. Provisional: criteria marked — are not yet measured and are left out of the average. A rating of structure and market depth, not a price forecast or investment advice. How the grade is built · Highest-graded cryptocurrencies.

Supply

244,935,420 GRIN are in circulation, against no fixed cap — issuance has no defined end.

How it was launched

No premine. No premine, no founder allocation, no public sale — the chain started empty and every coin was earned through mining or validating.

The work behind it

Grin is secured by 3.72 kH/s of its own work. Hashrate does not compare across algorithms — a SHA-256 hash and a Scrypt hash cost different amounts to produce.

What a regulator has said

No SEC/CFTC determination — unclassified.

The regulator's position, reported as stated, not CoinSpectrum's. Assets nobody has ruled on are left unclassified rather than sorted by a guess.

How CoinSpectrum ranks Grin

Grin is #194 among cryptocurrencies and #1473 in the market ranking, which lists wrapped coins, staked derivatives, stablecoins and tokens alongside them. CoinSpectrum counts an asset once, and counts only cryptocurrencies: assets with their own blockchain and their own consensus. A wrapped coin, a staked derivative or a stablecoin is a claim on something already counted; a token, memecoin or otherwise, runs on another chain's blocks. All of them are listed, each in its own section, and none is added to the total. The 1279 places between Grin's two ranks are held by claims and tokens, not by other networks. The methodology sets out the rule and the counting rule argues for it.

The price above is the median of the exchanges the site reads live, checked every minute and cross-checked against a market snapshot (how market data is gathered). The grade is scored on published criteria, each with its source (the method). The site is independent, nothing on it is a paid placement, and its statements are signed (about CoinSpectrum, the manifesto).
