Neptune Cash ranks #268 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1680: 1412 of the 1679 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 2743 non-native assets CoinSpectrum lists above it by market cap, about 80% are tokens, 16% are claims on other assets and 4% are memecoins.

| Cryptocurrency Standards (Source) | 6 | group average, 9 of 13 measured |
| Sound Money Qualities (6 checks) | 6 | 3 of 5 points, 1 not yet measured source |
| Scarcity: a fixed cap that holds, and a supply near 21 million | 9.8 | fixed maximum supply of 42 million: supply scale 9.6, cap 10 |
| Durability: five years or more with no halt, freeze or reversal | ✗ | 1 full year since its first recorded price, 2 halts, freezes or reversals in five years |
| Fungibility: every unit interchangeable, none the protocol can freeze or set apart | ✗ | an authority can freeze funds: The core team has twice reset ledger state by software release (a 2025 reboot that required balance redemption and a 2026 rollback of about a week), and its planned Lustration Barrier will make pre-fork UTXOs unspendable once a supply counter reaches zero. |
| Divisibility: the smallest unit worth a cent or less | ✓ | 30 decimal places, the smallest unit worth $2.6e-31 |
| Portability: fees of a cent or less and capacity for real demand | – | |
| 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) | ✗ | neptune-core v0.19.3: no Dandelion or built-in Tor. |
| Hidden amounts (confidential transactions, RingCT, shielded pools, Mimblewimble) | ✓ | UTXO amounts are committed and proven with Triton VM zk-STARKs (only pre-HardforkBeta UTXOs must be lustrated when spent). |
| Hidden sender and receiver (ring signatures or zero-knowledge proofs, one-time or stealth addresses) | ✓ | Mutator sets make spent inputs unlinkable to their outputs, and receivers get one-time UTXO notifications. |

| Features (3 checks) | 6.7 | 2 of 3 passed |
| Payments safe to accept within seconds | ✗ | Blocks are about 9.8 minutes apart with probabilistic confirmation. |
| Pruned nodes: a full node can validate and drop old history | ✓ | Only archival nodes keep history; other neptune-core nodes keep the mutator-set state. |
| Light clients verify payments from headers or proofs, without a trusted server | ✓ | Succinct validation: a node validates the chain from the latest block's recursive proof and checks payments with mutator-set membership proofs. |

| More than one maintained client | ✗ | 1 |
| Node software is open source | ✓ | neptune-core (Apache-2.0) is developed by the Neptune Cash core team (Alan Szepieniec, Thorkil Schmidiger and others) from the founding company, which decides reboots and hard forks. |
| Real on-chain use: 1,000+ transactions a day | – | |

| 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 | UTXOs are locked by Triton VM lock scripts proven in zero knowledge and used for spending conditions only; consensus recognises only the native-currency and time-lock type scripts. |
| Multisig and time locks | – | The TimeLock type script releases coins at a set date, but no m-of-n lock script is implemented or documented in neptune-core, so multisig could not be established. |
| Atomic swaps with other chains | – | The standard lock script is a hash lock on a spending key, 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 Neptune Cash consensus rules. |
| Cross-chain messaging the chain verifies itself | ✗ | No protocol-level cross-chain messaging. |
| Non-fungible tokens | ✗ | Only the native-currency and time-lock type scripts are recognised, so no NFTs. |
| Decentralisation | 6.4 | section average, 6 of 8 measured |
| Censorship resistant (Source) | 0 | An authority can halt the chain or freeze funds: The core team has twice reset ledger state by software release (a 2025 reboot that required balance redemption and a 2026 rollback of about a week), and its planned Lustration Barrier will make pre-fork UTXOs unspendable once a supply counter reaches zero. source |

| Premine (allocated at launch) | 9.3 | 7.42% of today's supply allocated at launch to founders, a company, a foundation or investors. A genesis premine of 831,488 NPT (1.98% of the 42M cap) was sold to investors. Against it, ~11.21M NPT is issued today: the August 2025 genesis (3,559,168 NPT = premine + 21,310 x 128 NPT redistributed from the first chain) plus 59,776 blocks x 128 NPT. source |
| Fundraising | 9.3 | Sold by its issuer or insiders: 7.42% of supply was theirs to sell, 7.42% sold so far. The project says the premine was distributed to investors in its initial funding round to bootstrap development; 831,488 / ~11.21M. A premine of 831,488 NPT (1.98% of the cap) was sold to investors in an initial funding round, run by a founding company that says it will dissolve after launch. The amount raised and the investors are not published. source |
| Developer share (after launch) | 10 | No developer share: every new coin goes to the miners or validators who produce blocks. The 128 NPT subsidy goes to the block composer and the proof-of-work guesser (both block producers); the consensus code has no developer or foundation share. Skipped subsidies from the first chain went to a claims fund for redeeming old balances, not to the team. source |

| Halt, freeze or reversal, 2025-07-05 | ✗ | After an undetectable inflation bug was found on 4 July 2025, the team abandoned the February 2025 chain at block 21,310 and relaunched from a new genesis (5 Aug 2025) holding the premine plus a claims fund; old holders had to redeem their balances with ownership proofs. |
| Halt, freeze or reversal, 2026-01-21 | ✗ | A Triton VM soundness flaw (proofs could be forged) was disclosed; the network stopped until v0.6.0 on 3 Feb 2026, which rolled the chain back to block 23,400, discarding about a week of history. |
| Age (years since genesis) (Source) | 1 | 1 full year since 2025-10-10, the first day with a recorded price (genesis not yet researched, so the age can only be understated). |

| Shipped a privacy improvement in two years, +1 | ✓ | HardforkDelta (~24 Sep 2026, height 55,000, neptune-core 0.17-0.19): proof version 8 (Triton VM v8), whose randomized quotient table gives proofs an explicit zero-knowledge property. |
| Shipped a scaling upgrade in two years, +1 | ✓ | HardforkAlpha (14 Nov 2025, height 15,000): PoW preprocessing reusable across block proposals, adopted to increase transaction throughput. |

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.

The project says the premine was distributed to investors in its initial funding round to bootstrap development; 831,488 / ~11.21M.
The 128 NPT subsidy goes to the block composer and the proof-of-work guesser (both block producers); the consensus code has no developer or foundation share. Skipped subsidies from the first chain went to a claims fund for redeeming old balances, not to the team.
The genesis coinbase (1.4236672e37 base units at 4e30 per NPT) equals 3,559,168 NPT = 831,488 premine + 21,310 x 128, which confirms the premine figure. The explorer's 'fee' field shows about half of each coinbase passed to the guesser.

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 Cash is #268 among cryptocurrencies and #1680 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 1412 places between Neptune Cash'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).
