OC Protocol ranks #490 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5621: 5131 of the 5620 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 OC Protocol'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) | 6.5 | group average, 10 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 | – | |
| 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 | ✓ | 8 decimal places, the smallest unit worth $1.5e-11 |
| Portability: fees of a cent or less and capacity for real demand | ✗ | about 30 transactions a second (2.7 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 | ✓ | OC Protocol's Bitcoin-derived node (OC-CryptoCurrency/OCP) 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) | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): no Dandelion relay in the node; Tor is only an optional proxy setting (-tor/-onion) the user must configure. |
| Hidden amounts (confidential transactions, RingCT, shielded pools, Mimblewimble) | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): Bitcoin-style transparent outputs; no confidential amounts. |
| Hidden sender and receiver (ring signatures or zero-knowledge proofs, one-time or stealth addresses) | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): Bitcoin-style transparent addresses; no ring signatures, zero-knowledge spends or stealth addresses. |
| Scalability (fees, throughput, block time, block space, features) | 4.5 | 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) | 2.7 | about 29.5 simple transactions a second |
| 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) | 6.4 | 2 MB limit, 4 MB per 10 minutes |
| Features (3 checks) | 0 | 0 of 3 passed |
| Payments safe to accept within seconds | ✗ | Ten-minute PoW and PoS targets (about 5 minutes combined) with probabilistic confirmation. |
| Pruned nodes: a full node can validate and drop old history | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): no -prune option; the node keeps the full block history. |
| Light clients verify payments from headers or proofs, without a trusted server | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): hybrid PoW/PoS chain; stake blocks cannot be checked from headers without the UTXO set and the protocol has no light-client proof scheme. |
| 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 three under 75% | – | |
| More than one maintained client | ✗ | 0 |
| Node software is open source | ✓ | Single repository in the OC-CryptoCurrency GitHub organisation, though it describes the roadmap as community-led. |

| No 51% attack or deep reorganisation in five years | ✓ | |
| Programmability (tokens, contracts, 5 checks) | 3.3 | 3 of 9 points source |
| Token issuance | 0 | No token issuance on the chain itself |
| Smart contracts: scripting for spending conditions | 1 | OCP 2.0 (Jul 2018; later commits only add checkpoints): Bitcoin-style Script limited to spending conditions; no contract platform. |
| Multisig and time locks | ✓ | OCP 2.0 (Jul 2018; later commits only add checkpoints): CHECKMULTISIG plus OP_CHECKLOCKTIMEVERIFY enforced by the block-validation script flags (src/main.cpp), giving absolute time locks. |
| Atomic swaps with other chains | ✓ | OCP 2.0 (Jul 2018; later commits only add checkpoints): hash-locked, CHECKLOCKTIMEVERIFY-refund HTLC scripts are expressible, as in Bitcoin. |
| An exchange built into the protocol | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): no order book or market maker in the ledger rules. |
| Cross-chain messaging the chain verifies itself | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): no cross-chain message or light-client verification in the protocol. |
| Non-fungible tokens | ✗ | OCP 2.0 (Jul 2018; later commits only add checkpoints): no token or NFT type in the consensus rules. |
| Decentralisation | 7.9 | section average, 6 of 8 measured |
| Censorship resistant (Source) | 10 | No authority can halt the chain or freeze funds: No master checkpoint key or freeze function in the code. source |

| Unfixed vulnerability, disclosed 2024-07-03, −1 | ✗ | CVE-2024-52914: crafted orphan transactions can stall the node for hours in the uninterruptible orphan-resolution loop; still in OC Protocol 1.0.2. |
| Unfixed vulnerability, disclosed 2024-07-03, −1 | ✗ | CVE-2020-14198: misbehaving peers are auto-banned into an unbounded ban list, so many attacker addresses can exhaust CPU and memory; still in OC Protocol 1.0.2. |
| Unfixed vulnerability, disclosed 2024-07-31, −1 | ✗ | CVE-2024-52919: addr-message spam can overflow the address manager's 32-bit id counter and crash the node, with no addr rate limit; still in OC Protocol 1.0.2. |
| Unfixed vulnerability, disclosed 2024-09-18, −1 | ✗ | CVE-2019-25220: a long low-difficulty header chain can exhaust memory because the node has no headers pre-synchronisation; still in OC Protocol 1.0.2. |
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.

None; Blackcoin fork launched as a 'cryptocurrency (social) experiment' via BitcoinTalk.
No sale documented.
Whole PoW subsidy to the miner; PoS stakers receive transaction fees only.
The OCP domain has lapsed to an unrelated operator; the README links three BitcoinTalk threads for later forks, which were not reviewed.

No source we can reach publishes a hashrate for OC Protocol.
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.
OC Protocol is #490 among cryptocurrencies and #5621 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 5131 places between OC Protocol'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).
