Universal Currency ranks #408 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5443: 5035 of the 5442 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. Fewer than six of Universal Currency's nine network-security points are measured yet. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.
| Criterion | Score | Basis |
|---|---|---|
| Leading Consensus Mechanisms (Source) | 4.5 | group average |
| Consensus: leader ladder | 4.5 | Hybrid: 4.5 of 10 on the ladder of consensus families ranked by their largest chain's market cap |
| Consensus: family ladder | 4.5 | Hybrid: 4.5 of 10 on the ladder of families ranked by the combined market cap of their chains |
| Cryptocurrency Standards (Source) | 7.7 | group average, 10 of 13 measured |
| Sound Money Qualities (6 checks) | 7.8 | 3.9 of 5 points, 1 not yet measured source |
| Scarcity: a fixed cap that holds, and a supply near 21 million | 9.4 | fixed maximum supply of 210 million: supply scale 8.7, cap 10 |
| Durability: five years or more with no halt, freeze or reversal | ✓ | 11 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 | ✓ | 8 decimal places, the smallest unit worth $6.3e-11 |
| Portability: fees of a cent or less and capacity for real demand | – | about 1,475 transactions a second (9.1 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; no light clients or pruned nodes |
| Privacy (5 checks) | 4 | 2 of 5 passed source |
| Whitepaper privacy: keys are not tied to an identity | ✓ | Universal Currency's Bitcoin-derived node (unitcurrency/unitcurrency) has no identity rule: anyone generates keys and receives and sends the coin. |
| 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) | ✗ | UnitCoin 1.0.2.1 (Nov 2017, PPCoin-era code): no Dandelion; Tor is only used if the operator runs and configures it. |
| Hidden amounts (confidential transactions, RingCT, shielded pools, Mimblewimble) | ✗ | Transparent Bitcoin-style amounts; no confidential transactions. |
| Hidden sender and receiver (ring signatures or zero-knowledge proofs, one-time or stealth addresses) | ✗ | Transparent addresses and inputs; no ring signatures or stealth addresses. |
| Scalability (fees, throughput, block time, block space, features) | 7.2 | average of 4 parts source |
| Fees ($0.001 or less 10, $1 or more 0) | – | not yet measured |
| Throughput (2,478 a second, the busiest network's peak day, 10; 119, the median of the ten busiest, 5) | 9.1 | about 1,475 simple transactions a second |
| 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) | 10 | 20 MB limit, 200 MB per 10 minutes |
| Features (3 checks) | 3.3 | 1 of 3 passed |
| Payments safe to accept within seconds | ✓ | The PPCoin-style node has transaction replacement disabled and relays the first-seen spend; one-minute blocks alone would not qualify. |
| Pruned nodes: a full node can validate and drop old history | ✗ | UnitCoin 1.0.2.1 (Nov 2017, PPCoin-era code) has no pruning mode; nodes keep every block. |
| Light clients verify payments from headers or proofs, without a trusted server | ✗ | UnitCoin (PoW/PoS) (pre-BIP37 code) serves no Merkle proofs or block filters, so light wallets trust servers. |
| 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 | ✗ | 0 |
| Node software is open source | ✓ | Small anonymous developer team in the unitcurrency GitHub organisation; inactive since 2017. |
| Real on-chain use: 1,000+ transactions a day | – | |
| No 51% attack or deep reorganisation in five years | ✓ | |
| Programmability (tokens, contracts, 5 checks) | 1.1 | 1 of 9 points source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts: scripting for spending conditions | 1 | Universal Currency runs Bitcoin-style Script limited to spending conditions (signatures, hash locks, multisig); no contract VM or token introspection. |
| Multisig and time locks | ✗ | OP_CHECKMULTISIG is present, but the PPCoin-era src/script.h has no OP_CHECKLOCKTIMEVERIFY or OP_CHECKSEQUENCEVERIFY (0xb1 is still OP_NOP2), so Script cannot enforce a time lock. |
| Atomic swaps with other chains | ✗ | Without a consensus-enforced CLTV or CSV, Universal Currency Script cannot express the time-locked refund of an HTLC; only pre-signed nLockTime refunds, which pre-SegWit malleability makes unsafe. |
| An exchange built into the protocol | ✗ | No exchange or order book in the Universal Currency consensus rules. |
| Cross-chain messaging the chain verifies itself | ✗ | Universal Currency nodes verify no other chain; no protocol-level cross-chain messaging. |
| Non-fungible tokens | ✗ | No token or NFT type in the Universal Currency consensus rules. |
| Decentralisation | 9.5 | section average, 6 of 8 measured |
| Censorship resistant (Source) | 10 | No authority can halt the chain or freeze funds: No protocol-level party can freeze, blacklist or claw back coins. source |
| No central team (Source) | 10 | No central team: Small anonymous developer team in the unitcurrency GitHub organisation; inactive since 2017. source |

| Fundraising | 10 | No sale of the coin source |
| Developer share (after launch) | 10 | No developer share: every new coin goes to the miners or validators who produce blocks. PoW and PoS rewards go entirely to block producers; no developer share in the code. 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.

clients is 0 because the only client's last release (2017) is older than 24 months. Every Universal Currency web property is offline and CMC shows 0 circulating, so the chain may be dead.

No source we can reach publishes a hashrate for Universal Currency.
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.
Universal Currency is #408 among cryptocurrencies and #5443 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 5035 places between Universal Currency'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).
