Francs (FRN)
Francs ranks #417 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #5477: 5060 of the 5476 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 Francs 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.

| Multisig and time locks (Without a third party) | ✓ | Francs v1.10.4.2 (Jul 2017): CHECKMULTISIG plus OP_CHECKLOCKTIMEVERIFY enforced by the block-validation script flags (src/main.cpp), giving absolute time locks. Enforcement starts once version-4 blocks reach a supermajority. |

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.

Apparently a dead Scrypt coin (launched about January 2016, aimed at French users); no code, explorer or community could be found, so almost every field is null. clients is 0 because no maintained implementation exists.

How CoinSpectrum ranks Francs
Francs is #417 among cryptocurrencies and #5477 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 5060 places between Francs'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).
