Karlsen (KLS)

Karlsen ranks #272 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #2542: 2270 of the 2541 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. Of the 2808 non-native assets CoinSpectrum lists above it by market cap, about 81% are tokens, 16% are claims on other assets and 3% are memecoins.

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.

Genesis carries an empty UTXO commitment (EMPTY_MUHASH) and the coinbase code has no developer output, so everything is mined from block one; listing sites and the project describe no premine and no ICO.

No ICO or presale found.

No sale documented.

Coinbase pays the block subsidy and fees to miners only; no developer fund in rusty-karlsen's coinbase code.

Mainnet started around November 2023 (back-calculated from the DAA score of the September 2024 hard fork). The table's total, 4.961B KLS, matches the input max. The inflation figure assumes the DAA score has tracked wall-clock time at 1 BPS; the 10-BPS 'crescendo' upgrade is not activated on mainnet. With all Karlsen web infrastructure unreachable, the network's current state could not be checked.

The work behind it

Karlsen is secured by 17 GH/s of its own work. Hashrate does not compare across algorithms — a SHA-256 hash and a Scrypt hash cost different amounts to produce.

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 Karlsen

Karlsen is #272 among cryptocurrencies and #2542 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 2270 places between Karlsen'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).
