Californium (CF)

Californium ranks #407 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5441: 5034 of the 5440 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 Californium'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.

Privacy4section average
Privacy (5 checks)42 of 5 passed source
Protocol level privacy (Keys not tied to an identity · Whitepaper §10)✓Californium's Bitcoin-derived node (Californium/Californium) has no identity rule: anyone generates keys and receives and sends the coin.
UTXO ledger (A new key for each payment · Whitepaper §2, §9)✓
Network privacy (Origin hidden by default)✗Californium (Bitcoin 0.9.5 base, last commit 2015): no Dandelion; Tor is only used if the operator runs and configures it.
Hidden amounts (Amounts confidential)✗Transparent Bitcoin-style amounts; no confidential transactions.
Hidden parties (Sender and receiver hidden)✗Transparent addresses and inputs; no ring signatures or stealth addresses.
Programmability (tokens, contracts, 5 checks)1.11 of 9 points source
Token issuance0No token issuance on the chain itself
Smart contracts (Scripting for spending conditions)1Californium runs Bitcoin-style Script limited to spending conditions (signatures, hash locks, multisig); no contract VM or token introspection.
Multisig and time locks (Without a third party)✗OP_CHECKMULTISIG is present, but the Bitcoin 0.9.5-based 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, Californium Script cannot express the time-locked refund of an HTLC; only pre-signed nLockTime refunds, which pre-SegWit malleability makes unsafe.
Native exchange (Built into the protocol)✗No exchange or order book in the Californium consensus rules.
Cross-chain messaging (Verified by the chain itself)✗Californium nodes verify no other chain; no protocol-level cross-chain messaging.
NFTs (Carried by the chain's rules)✗No token or NFT type in the Californium consensus rules.

Twenty criteria, weighted equally. The Cryptocurrency Standards have five sections: sound money (six qualities: scarcity, durability, fungibility, portability, divisibility, verifiability), scalability (four measures and three features), security (miner pay and seven checks), decentralisation (censorship resistance, no central team, who can mint, nodes, holders, premine, fundraising and developer share) and privacy (five checks); programmability (token issuance, smart contracts and five checks) follows them. 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 work behind it

No source we can reach publishes a hashrate for Californium.

What a regulator has said

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.

How CoinSpectrum ranks Californium

Californium is #407 among cryptocurrencies and #5441 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 5034 places between Californium'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).
