MimbleWimbleCoin ranks #340 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #4484: 4144 of the 4483 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.

Grade pending. MimbleWimbleCoin's launch — how much went to insiders, whether it was sold to investors — is still being researched. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

| Cryptocurrency Standards (Source) | 5.8 | group average, 10 of 13 measured |
| Sound Money Qualities (6 checks) | 8.3 | 5 of 6 points source |
| Scarcity: a fixed cap that holds, and a supply near 21 million | 10 | fixed maximum supply of 20 million: supply scale 10, cap 10 |
| Durability: five years or more with no halt, freeze or reversal | ✓ | 6 full years since its first recorded price, no halt, freeze or reversal in five years |
| Fungibility: every unit interchangeable, none the protocol can freeze or set apart | ✓ | no authority can freeze, blacklist or set apart a coin |
| Divisibility: the smallest unit worth a cent or less | ✓ | 9 decimal places, the smallest unit worth $1.3e-8 |
| Portability: fees of a cent or less and capacity for real demand | ✗ | typical fee $0.0001; about 15 transactions a second (1.5 on the throughput scale; 5 is the busiest networks' median demand) |
| Verifiability: open-source nodes and checking without a trusted server | ✓ | node software open source; pruned nodes validate everything |
| Privacy (5 checks) | 8 | 4 of 5 passed source |
| Whitepaper privacy: keys are not tied to an identity | ✓ | Mimblewimble outputs need only blinding keys anyone generates; no identity rule. |
| UTXO ledger: a new key for each payment, no account linking every coin | ✓ | |
| Network-level privacy: the node hides where a transaction came from (Dandelion++, Tor or I2P, on by default) | ✓ | mwc-node: Dandelion++ stem relay in the transaction pool, and since 6.0.1 (Mar 2026) an embedded Tor client carries all peer connections by default. |
| Hidden amounts (confidential transactions, RingCT, shielded pools, Mimblewimble) | ✓ | Mimblewimble since launch (2019): Pedersen commitments and range proofs hide every amount. |
| Hidden sender and receiver (ring signatures or zero-knowledge proofs, one-time or stealth addresses) | ✗ | No addresses on chain, but inputs are spent openly (no ring signatures or ZK sender hiding) and the graph is only partly hidden by cut-through. |

| Block time (10 minutes 10, less either side) | 6.4 | a block every 1 minute |
| Block space per 10 minutes (32 MB or more 10) | 8.5 | 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 |
| Payments safe to accept within seconds | ✗ | One-minute proof-of-work blocks with probabilistic confirmation; no instant-lock or double-spend-proof mechanism. |
| Pruned nodes: a full node can validate and drop old history | ✓ | mwc-node runs non-archive by default (archive_mode off): spent outputs are pruned and nodes sync from a horizon snapshot. |
| Light clients verify payments from headers or proofs, without a trusted server | ✗ | Mimblewimble chain with no SPV-style light client; wallets trust a node. |
| Security (miner pay and 7 checks) | 3.9 | 3 of 7 points, 2 not yet measured source |
| Miners paid a day ($1,000 0, $10 million or more 10), 2 points | 0 | about $911 a day |

| Programmability (tokens, contracts, 5 checks) | 1.1 | 1 of 9 points source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts | 0 | Mimblewimble chain (Grin-derived mwc-node): outputs carry no scripts, only commitments and kernels. |
| Multisig and time locks | ✗ | Kernels carry lock heights and the wallet builds 2-of-2 Schnorr outputs for swaps, but there is no general m-of-n multisig in the protocol. |
| Atomic swaps with other chains | ✓ | mwc-wallet's swap module trades MWC against BTC, BCH, LTC, DASH, ZEC, DOGE and Ether with a multisig output and time-locked refund, working on mainnet. |
| An exchange built into the protocol | ✗ | The swap marketplace is a wallet feature, not part of the consensus rules. |
| Cross-chain messaging the chain verifies itself | ✗ | MWC nodes verify no other chain; no protocol-level cross-chain messaging. |
| Non-fungible tokens | ✗ | Transactions carry only the native coin; no token or NFT type. |
| Decentralisation | 6.2 | section average, 5 of 8 measured |

Secondary sources say the 10M were split into about 6M for a Bitcoin-holder airdrop (about 5.4M actually claimed), about 2M for the developers and 2M for a HODL programme; all of it was allocated by the founders. source |

Twenty criteria, weighted equally. The Cryptocurrency Standards have six sections: sound money qualities (six checks: scarcity, durability, fungibility, divisibility, portability, verifiability), privacy (five checks), scalability (four measures and three features), security (miner pay and seven checks), programmability (token issuance, smart contracts and five checks) and decentralisation (censorship resistance, no central team, who can mint, nodes, holders, premine, fundraising and developer share). 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.
0 of a maximum 20,000,000 MWC are in circulation — 0.0% of the total that will ever exist.
| Premine (allocated at launch) | 90.8% of today's supply |
|---|---|
| Developer share received since launch | 0% of today's supply |
| Developer share of new coins today | 0% |
The genesis block pays GENESIS_BLOCK_REWARD = 10,000,000.04 MWC (consensus.rs); against ~11.02M supply at height 3,625,920 (schedule sum) that is 90.8%. Secondary sources say the 10M were split into about 6M for a Bitcoin-holder airdrop (about 5.4M actually claimed), about 2M for the developers and 2M for a HODL programme; all of it was allocated by the founders.
No ICO is reported; funding of the founding team and any sale of its 2M allocation are not documented in a primary source found.
No public or private sale is documented; whether the developer allocation was later sold is not documented.
consensus::reward pays block reward plus fees to the miner; no developer or treasury output.
The genesis 10M (half the 20M cap) dominates supply; the breakdown of airdrop, developer and HODL allocations comes from a secondary summary, not a primary document. Input circulating supply of 0 is wrong: the chain is live at height 3,625,920 with ~11.02M issued. No attack or halt found.

MimbleWimbleCoin is secured by 9.66 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.
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.
MimbleWimbleCoin is #340 among cryptocurrencies and #4484 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 4144 places between MimbleWimbleCoin'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).
