Grin (GRIN)
Grin ranks #184 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1350: 1166 of the 1349 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 1598 non-native assets CoinSpectrum lists above it by market cap, about 61% are tokens, 32% are claims on other assets, 6% are memecoins and 1% are NFT collections.

| Governance (Source) | 10 | No authority can halt the chain or freeze funds: No protocol party can freeze or claw back coins or halt the chain. source |
| No central team (Source) | 10 | No central team: The Rust reference node is maintained by volunteer core and community developers funded by donations (no company or foundation employer); Grin++ is a separate C++ implementation by an independent developer. source |

| Block time (10 minutes 10, less either side) | 6.4 | a block every 1 minute |
| Block space per 10 minutes (24 MB or more 10: the ten busiest networks' median demand, 16.4 MB, and half again for growth) | 9 | 1.37 MB limit (converted from its gas, compute, mass or count limit), 13.7 MB per 10 minutes |
| Features (3 checks) | 3.3 | 1 of 3 passed |
| Fast payments (Safe to accept within seconds · Whitepaper abstract, §1, §2 and §11) | ✗ | One-minute blocks with probabilistic confirmation; transactions are interactive and there is no protected zero-confirmation or instant-lock mechanism. |
| Pruned nodes (Old history dropped, every rule checked · Whitepaper §7) | ✓ | Default node mode is fast-sync and pruned (keeps UTXO set, kernels and recent blocks); archive_mode is opt-in. |
| Light clients (Payments verified from headers · Whitepaper §8) | ✗ | No light-client protocol; wallets trust their node. |
| Privacy | 9.2 | 9.2 of 10: whitepaper privacy 7 of 7, extra features 2.2 of 3 source |
| Protocol level privacy (Keys not tied to an identity · Whitepaper §10) | 10 | Mimblewimble outputs are Pedersen commitments controlled by blinding factors users generate; there are no accounts or identities. |
| UTXO ledger (Separate outputs, change to a new address · Whitepaper §2, §9) | 10 | Coins are separate unspent outputs: a payment spends whole outputs and sends the change to a new address, so the coins in one wallet need not share a history. |
| HD addresses (A new address for each payment, unlinked · Whitepaper §10) | 10 | No addresses on chain: each output is a new commitment, so no two payments share a destination |
| Hidden amounts (Amounts confidential) | 10 | Mimblewimble Pedersen commitments with range proofs hide every amount since launch (2019). |
| Hidden parties (Sender and receiver hidden) | 0 | 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. |
| Network privacy (Origin hidden by default) | 10 | Grin node relays transactions through Dandelion stem/fluff by default (stem_probability 90, always_stem_our_txs in the default config). |
| Programmability | 1.1 | 1 of 9 points source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts | 0 | Mimblewimble 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 DEX (Trades the coin itself, not a claim) | ✓ | Traded as itself, not as a wrapped token or a claim: Bisq. |
| Cross-chain messaging (Verified by the chain itself) | ✗ | No cross-chain feature in the protocol. |
| NFTs (Carried by the chain's rules) | ✗ | No token or NFT type in the protocol. |
| Demand | 2.4 | average of 7 measures |
| Exchanges (10 or more: 10) | 1 | 1 exchange |
| Daily volume ($10K 0, $1B or more 10) | 0 | $6,313 traded in 24 hours; #2982 by volume on the exchanges the site reads (scored on the median day of the last 30, $2,998) |
| Turnover (volume ÷ market cap, 5% a day: 10) | 0.6 | 0.09% of its market cap a day, median of the last 30 days |
| Order-book depth (±2% of the price ÷ market cap, 1%: 10) | 2.7 | $222 within 2% of the price on 1 exchange, 0.01% of its market cap, median of the last 15 days |
| Market cap ($1M 0, $10B or more 10) | 1.3 | $3.5M, 1.3 on a scale of 2.5 points per tenfold |
| Paper trading (futures, options and margin ÷ market cap, 0%: 10, 100%: 0) | 10 | no futures, options or margin on the exchanges read |
| Wallet support (wallets that hold it, 10 or more: 10) | 1 | its own node and wallet, counted as 1: no wallet in the site's directory lists it yet |

Ten sections, weighted equally, each 0 to 10: consensus (the two ladders), supply (the supply scale and a fixed cap that holds), distribution (premine, fundraising, developer share, holders), decentralisation (governance, no central team, who can mint, nodes), security, scalability, privacy, programmability (what the scripting layer can do beyond the whitepaper's payment system), demand, and record (age, development, conduct). They are built from the criteria in the second table: privacy, scalability, security and decentralisation are the Cryptocurrency Standards among them, as follows: privacy (the whitepaper's three checks a base of 7 of 10, three extra features up to 3 more), scalability (four measures and three features), security (pool diversity, network activity, hashrate, clients and two checks) and decentralisation (governance, no central team, who can mint, nodes, holders, premine, fundraising and developer share); programmability (token issuance, smart contracts and five checks) follows them, and supply and demand are two: the supply, scored against 21 million, and demand, the average of seven measures of the market and the wallets. Provisional: parts 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.

246,063,720 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 3.85 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 #184 among cryptocurrencies and #1350 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 1166 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).
