Bitcoin Blake2B ranks #504 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1054: 550 of the 1053 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.

| Privacy (5 checks) | 4 | 2 of 5 passed source |
| Whitepaper privacy: keys are not tied to an identity | ✓ | Bitcoin Blake2B's Bitcoin-derived node (bitcoinknots/bitcoin (29.x-knots)) 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) | ✗ | BTCB2 node (Bitcoin Knots 29.x branch with BLAKE2b PoW, fork Aug 2026): no Dandelion; Tor needs user setup. |

| Light clients verify payments from headers or proofs, without a trusted server | ✓ | BTCB2 (Bitcoin Knots 29.x lineage): proof-of-work chain whose node serves BIP37 merkleblock proofs (-peerbloomfilters) and BIP157 compact block filters (-peerblockfilters). |

| Smart contracts: scripting for spending conditions | 1 | Bitcoin Blake2B (Bitcoin Knots 29.x fork, BLAKE2b PoW since 2026): Bitcoin Script and Tapscript with BIP-110 data limits; no contract platform. |
| Multisig and time locks | ✓ | Bitcoin Blake2B: CHECKMULTISIG, CHECKLOCKTIMEVERIFY and CHECKSEQUENCEVERIFY inherited from Bitcoin; BIP-110's limits (256-byte pushes, no OP_IF in Tapscript) leave P2SH/P2WSH multisig and lock times intact. |
| Atomic swaps with other chains | ✓ | Bitcoin Blake2B: P2WSH HTLCs with OP_IF and small hash preimages stay valid under BIP-110 (only Tapscript OP_IF is banned). |
| An exchange built into the protocol | ✗ | Bitcoin Blake2B: no exchange in the protocol. |
| Cross-chain messaging the chain verifies itself | ✗ | Bitcoin Blake2B: no cross-chain messaging in the protocol. |
| Non-fungible tokens | ✗ | Bitcoin Blake2B: no token or NFT type in the consensus rules (and BIP-110 restricts inscription-style data). |

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.
About 20.1 million BTCB2 exist on paper: Bitcoin’s whole ledger as of the split (20.07M, lost and dormant coins included), plus 3.125 per block mined since. Nobody publishes how much of that is held by anyone active on this chain, so no market cap is shown — price × 20.1M would claim around $10 billion for a coin that trades under $2 million a day.

Bitcoin Blake2B is secured by 47 PH/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.
Bitcoin Blake2B is #504 among cryptocurrencies and #1054 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 550 places between Bitcoin Blake2B'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).
