Signum ranks #226 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1776: 1550 of the 1775 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 2013 non-native assets CoinSpectrum lists above it by market cap, about 77% are tokens, 18% are claims on other assets and 5% are memecoins.

| Premine (allocated at launch) | 10 | 0% of today's supply allocated at launch to founders, a company, a foundation or investors. Burstcoin, launched 2014 (rebranded Signum in 2021), had no premine, ICO or airdrop per the signum-node README. All supply came from open Proof-of-Capacity/Commitment mining: 10,000 SIGNA/block, falling 5% a month to a 100 SIGNA floor, about 2,138,119,200 up to block 972k. source |

| Developer share (after launch) | 10 | No developer share: every new coin goes to the miners or validators who produce blocks. No cut. getBlockRewardDistribution returns null for mainnet (NetworkParametersBase), so the full block reward (now the 100 SIGNA floor) goes to the miner or its reward recipient; the SNA fee cash-back is a fee rebate, not issuance. source |

| Halt, freeze or reversal, 2026-05-19 | ✗ | A miner exploited an integer overflow in fee cash-back accounting (CVE-2026-48486, GHSA-4vjp-2m22-r2q9) at block 1,541,011 to mint an inflated block reward; emergency v3.9.7 blocked the exploiting account, and v3.9.8 the same day required every node to roll back to before block 1,541,010, reversing the exploit blocks. The canonical chain shows a ~9-hour gap between blocks 1,541,010 (07:46 UTC) and 1,541,011 (16:50 UTC). |

| Shipped a security fix in two years, +1 | ✓ | Signum Node v3.9.7–v3.9.8, May 2026: chain-consistency patch and cashback-fee overflow fix requiring a rollback; v3.9.10–v3.9.11 (Jun 2026) monetary-overflow hardening. |
| Negative | ||
| Exploit of the chain, 2026-05-19, −1 | ✗ | An integer overflow in SMART_FEES fee distribution was exploited at block 1,541,011 to claim far more than the block reward; v3.9.7 blocked the account and v3.9.8-3.9.9 fixed the arithmetic. |
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.

Burstcoin, launched 2014 (rebranded Signum in 2021), had no premine, ICO or airdrop per the signum-node README. All supply came from open Proof-of-Capacity/Commitment mining: 10,000 SIGNA/block, falling 5% a month to a 100 SIGNA floor, about 2,138,119,200 up to block 972k.
None.
No cut. getBlockRewardDistribution returns null for mainnet (NetworkParametersBase), so the full block reward (now the 100 SIGNA floor) goes to the miner or its reward recipient; the SNA fee cash-back is a fee rebate, not issuance.
The SNA cash-back is a fee rebate, not a share of block rewards, so it doesn't count as a developer tax. The 'SNR' node-operator awards are community-funded bounties.

No source we can reach publishes a hashrate for Signum.
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.
Signum is #226 among cryptocurrencies and #1776 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 1550 places between Signum'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).
