Neptune ranks #352 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #4719: 4367 of the 4718 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.

| Consensus: family ladder | 10 | Proof of work: 10 of 10 on the ladder of families ranked by the combined market cap of their chains |
| Cryptocurrency Standards (Source) | 7.3 | group average, 10 of 13 measured |
| Sound Money Qualities (6 checks) | 7.5 | 3 of 4 points, 2 not yet measured source |
| Scarcity: a fixed cap that holds, and a supply near 21 million | – | |
| Durability: five years or more with no halt, freeze or reversal | ✗ | 0 full years since its first recorded price, one 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 | ✓ | 30 decimal places, the smallest unit worth $5.2e-31 |
| Portability: fees of a cent or less and capacity for real demand | – | typical fee $0.0067 |
| Verifiability: open-source nodes and checking without a trusted server | ✓ | node software open source; light clients verify from headers or proofs |
| Privacy (5 checks) | 8 | 4 of 5 passed source |
| Whitepaper privacy: keys are not tied to an identity | ✓ | UTXOs are locked by lock scripts from 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) | ✗ | xnt-core v0.3.0: no Dandelion or built-in Tor. |
| Hidden amounts (confidential transactions, RingCT, shielded pools, Mimblewimble) | ✓ | UTXO amounts are hidden in commitments proven with Triton VM zk-STARKs (inherited from Neptune Cash). |
| Hidden sender and receiver (ring signatures or zero-knowledge proofs, one-time or stealth addresses) | ✓ | Mutator sets unlink spent inputs and receivers get one-time UTXO notifications, so sender and receiver are hidden. |
| Scalability (fees, throughput, block time, block space, features) | 7.6 | average of 3 parts source |
| Fees ($0.001 or less 10, $1 or more 0) | 7.2 | typical fee $0.0067 |
| Throughput (2,478 a second, the busiest network's peak day, 10; 119, the median of the ten busiest, 5) | – | not yet measured |
| Block time (10 minutes 10, less either side) | 8.9 | a block every 5 minutes |
| Block space per 10 minutes (32 MB or more 10) | – | not yet measured |
| Features (3 checks) | 6.7 | 2 of 3 passed |
| Payments safe to accept within seconds | ✗ | Blocks target 588 seconds with probabilistic confirmation; no instant locks. |
| Pruned nodes: a full node can validate and drop old history | ✓ | Non-archival xnt-core nodes keep only the mutator-set state, not the block history. |
| Light clients verify payments from headers or proofs, without a trusted server | ✓ | Neptune-derived succinct chain: a node validates the chain from the latest recursive block proof and checks payments by mutator-set membership proofs. |
| Security (miner pay and 7 checks) | — | 2 of 3 points, 6 not yet measured source |
| Miners paid a day ($1,000 0, $10 million or more 10), 2 points | – | |
| Its own hashrate: at least half its algorithm's largest, not merge-mined | – | |
| Largest pool or validator under 50% | – | |
| Largest three under 75% | – | |
| More than one maintained client | ✗ | 1 |
| Node software is open source | ✓ | neptune-core lives in the Neptune-Crypto GitHub organisation (Apache-2.0) and was built by Triton Software AG, which said it would dissolve after launch; the same core team still drives every hard fork. |
| Real on-chain use: 1,000+ transactions a day | – | |
| No 51% attack or deep reorganisation in five years | ✓ | |
| Programmability (tokens, contracts, 5 checks) | 1.4 | 1 of 7 points, 2 not yet researched source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts: scripting for spending conditions | 1 | xnt-core (Neptune Cash fork) locks UTXOs with Triton VM lock scripts proven in zero knowledge, used for spending conditions only; type scripts are limited to the native currency and time lock. |
| Multisig and time locks | – | The TimeLock type script gives time-locked spending, but no m-of-n lock script is implemented or documented, so multisig could not be established. |
| Atomic swaps with other chains | – | Lock scripts are standard hash locks and no HTLC or adaptor-signature swap is implemented, so swaps could not be established. |
| An exchange built into the protocol | ✗ | No exchange in the consensus rules. |
| Cross-chain messaging the chain verifies itself | ✗ | No protocol-level cross-chain messaging. |
| Non-fungible tokens | ✗ | Consensus recognises only the native-currency and time-lock type scripts, so no NFTs. |
| Decentralisation | 8.1 | section average, 6 of 8 measured |
| Censorship resistant (Source) | 10 | No authority can halt the chain or freeze funds: No party holds a freeze or clawback key; the lustration barrier that can make pre-barrier UTXOs unspendable is a fixed consensus rule, not a discretionary power. source |
| No central team (Source) | 0 | A central team directs it: neptune-core lives in the Neptune-Crypto GitHub organisation (Apache-2.0) and was built by Triton Software AG, which said it would dissolve after launch; the same core team still drives every hard fork. source |

| Holder concentration (Source) | — | Not yet measured |
| Premine (allocated at launch) | 9.3 | 7.4% of today's supply allocated at launch to founders, a company, a foundation or investors. Genesis premine of 831,488 coins (PREMINE_MAX_SIZE, 1.98% of the 42M asymptotic limit) for investors, advisers, bounties and, for unsold rights, the founders; current supply ~11.21M (831,488 premine + 2,727,680 claims pool for the 21,310 pre-reboot blocks + 59,777 blocks x 128 since the August 2025 reboot), so 831,488 / 11.21M = 7.4%. source |
| Fundraising | 9.3 | Sold by its issuer or insiders: 7.4% of supply was theirs to sell. Triton Software AG sold rights to premine tokens; by 2023-09 117,834 coins were sold (about 1.05% of today's supply) and 635,471 were still for sale, with unsold coins passing to founders and early employees in 2026. The final sold amount is not published. Triton Software AG (Zug, Switzerland) sold rights to future premine tokens to investors; CHF 1,079,450 received by September 2023 (implied premine valuation CHF 7.6M). source |
| Developer share (after launch) | 10 | No developer share: every new coin goes to the miners or validators who produce blocks. The 128-coin block subsidy (halving every 160,815 blocks) goes entirely to the block's composer and guesser, half of it time-locked for three years; no dev or treasury share in consensus. 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.

Soundness bugs in Triton VM proofs forced hard forks TvmProofVersion1 (2026-02-04) and Gamma (2026-06-18); the project added a 'lustration' counter to cap any undetected inflation from unsound proofs. No exploitation is documented. Supply is a computed estimate.

No source we can reach publishes a hashrate for Neptune.
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.
Neptune is #352 among cryptocurrencies and #4719 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 4367 places between Neptune'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).
