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.

Scarcity: a fixed cap that holds, and a supply near 21 million–
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-12
Portability: fees of a cent or less and capacity for real demand✗about 49 transactions a second (3.5 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; light clients verify from headers or proofs
Privacy (5 checks)42 of 5 passed source
Whitepaper privacy: keys are not tied to an identity✓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, no account linking every coin✓
Network-level privacy: the node hides where a transaction came from (Dandelion++, Tor or I2P, on 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 (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)5.3average of 4 parts source

Features (3 checks)3.31 of 3 passed
Payments safe to accept within seconds✗The chain is not verified to be producing blocks; its Bitcoin 0.8-era code would relay first-seen without replace-by-fee.
Pruned nodes: a full node can validate and drop old history✗Californium (Bitcoin 0.9.5 base, last commit 2015) has no pruning mode; nodes keep every block.
Light clients verify payments from headers or proofs, without a trusted server✓Californium (Bitcoin 0.9.5 base, last commit 2015) serves BIP37 Merkle proofs to SPV clients, which check the SHA-256 proof of work in headers.
Security (miner pay and 7 checks)—2 of 3 points, 6 not yet measured source

Node software is open source✓A single anonymous developer ('cfdev'); source files carry Bitcoin's MIT/X11 licence headers, though the repository has no licence file.

Programmability (tokens, contracts, 5 checks)1.11 of 9 points source
Token issuance0No token issuance on the chain itself
Smart contracts: scripting for spending conditions1Californium 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 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.
An exchange built into the protocol✗No exchange or order book in the Californium consensus rules.
Cross-chain messaging the chain verifies itself✗Californium nodes verify no other chain; no protocol-level cross-chain messaging.
Non-fungible tokens✗No token or NFT type in the Californium consensus rules.

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 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).
