Californium (CF)

CF price chart

Californium ranks #394 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5449: 5055 of the 5448 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.

CoinSpectrum Grade (Source)

Grade pending. No market cap or no daily volume is reported for Californium by any source the site reads. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

Section and criteria	Score	Basis

Premine (allocated at launch)	10	0% of today's supply allocated at launch to founders, a company, a foundation or investors. GetBlockValue pays 1 CF for the first 100 blocks ('ease in to 0 diff'), then 10 CF halving every 126,000 blocks with a 0.005 CF floor; the ANN (17 April 2015) states no premine or ICO and none appears in the code. source
Fundraising (share sold) (Source)	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. The whole subsidy goes to the miner; no developer output. source
Decentralisation	6.7	average of 3 parts
Governance (Source)	10	No authority can halt the chain or freeze funds: No protocol freeze key found. source
No central team (Source)	0	A central team directs it: A single anonymous developer ('cfdev'); source files carry Bitcoin's MIT/X11 licence headers, though the repository has no licence file. source

Features (3 checks)	3.3	1 of 3 passed
Fast payments (Safe to accept within seconds · Whitepaper abstract, §1, §2 and §11)	✗	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 (Old history dropped, every rule checked · Whitepaper §7)	✗	Californium (Bitcoin 0.9.5 base, last commit 2015) has no pruning mode; nodes keep every block.
Light clients (Payments verified from headers · Whitepaper §8)	✓	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.
Privacy	7	7 of 10: whitepaper privacy 7 of 7, extra features 0 of 3, 1 not yet researched source
Protocol level privacy (Keys not tied to an identity · Whitepaper §10)	10	Californium's Bitcoin-derived node (Californium/Californium) has no identity rule: anyone generates keys and receives and sends the coin.
UTXO ledger (Separate outputs, change to a new address · Whitepaper §2, §9)	10	Coins are separate unspent outputs: a payment spends whole outputs and sends the change to a new address, so the coins in one wallet need not share a history.
HD addresses (A new address for each payment, unlinked · Whitepaper §10)	–
Hidden amounts (Amounts confidential)	0	Transparent Bitcoin-style amounts; no confidential transactions.
Hidden parties (Sender and receiver hidden)	0	Transparent addresses and inputs; no ring signatures or stealth addresses.
Network privacy (Origin hidden by default)	0	Californium (Bitcoin 0.9.5 base, last commit 2015): no Dandelion; Tor is only used if the operator runs and configures it.
Programmability	1.1	1 of 9 points source
Token issuance	0	No token issuance on the chain itself
Smart contracts (Scripting for spending conditions)	1	Californium 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 DEX (Trades the coin itself, not a claim)	✗	No DEX found trading the coin itself: none on its own chain (DefiLlama), and not on THORChain, Maya, Chainflip, Komodo DeFi, BasicSwap, Bisq or Haveno (checked 2026-11-04).
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.
Demand	0.5	average of 2 measures

Paper trading (futures, options and margin ÷ market cap, 0%: 10, 100%: 0)	–	not measured
Wallet support (wallets that hold it, 10 or more: 10)	1	its own node and wallet, counted as 1: no wallet in the site's directory lists it yet
Record	6.7	average of 3 criteria
Age (years since genesis) (Source)	10	11 full years since 2015-04-22, the first day with a recorded price (genesis not yet researched, so the age can only be understated).

Unfixed vulnerability, disclosed 2024-07-03, −1	✗	CVE-2020-14198: misbehaving peers are auto-banned into a ban map that is never pruned, so many attacker addresses (cheap with IPv6) can grow memory without bound; the quadratic GETADDR scan does not exist in this older code; still in Californium HEAD. bitcoincore.org github.com
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 Californium HEAD. bitcoincore.org github.com

Ten sections, weighted equally, each 0 to 10: consensus (the two ladders), supply (the supply scale and a fixed cap that holds), distribution (premine, fundraising, developer share, holders), decentralisation (governance, no central team, who can mint, nodes), security, scalability, privacy, programmability (what the scripting layer can do beyond the whitepaper's payment system), demand, and record (age, development, conduct). They are built from the criteria in the second table: privacy, scalability, security and decentralisation are the Cryptocurrency Standards among them, as follows: privacy (the whitepaper's three checks a base of 7 of 10, three extra features up to 3 more), scalability (four measures and three features), security (pool diversity, network activity, hashrate, clients and two checks) and decentralisation (governance, no central team, who can mint, nodes, holders, premine, fundraising and developer share); programmability (token issuance, smart contracts and five checks) follows them, and supply and demand are two: the supply, scored against 21 million, and demand, the average of seven measures of the market and the wallets. Provisional: parts 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 #394 among cryptocurrencies and #5449 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 5055 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).
