Signum (SIGNA)

SIGNA price chart

Signum ranks #216 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1701: 1485 of the 1700 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 1978 non-native assets CoinSpectrum lists above it by market cap, about 61% are tokens, 32% are claims on other assets, 5% are memecoins and 1% are NFT collections.

CoinSpectrum Grade (Source)

Grade pending. No market cap or no daily volume is reported for Signum 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
Consensus	10	average of 2 criteria
By leader (its largest chain's market cap) (Source)	10	Proof of work: 10 of 10 on the ladder of consensus families ranked by their largest chain's market cap
By family (all its chains' market cap) (Source)	10	Proof of work: 10 of 10 on the ladder of families ranked by the combined market cap of their chains
Supply	7.2	the supply scale times 0.9, and a point for a fixed cap that holds
Supply (21 million scores 10)	8	no fixed maximum; 2.13 billion in circulation
Distribution	10	average of 3 parts
Holder concentration (Source)	–	Not yet measured
Active addresses	–	Not yet measured
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
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. 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
Decentralisation	10	average of 3 parts
Governance (Source)	10	No authority can halt the chain or freeze funds: No standing key can freeze coins or halt the chain; the May 2026 response blocked one exploiter account and rolled back blocks through an emergency client release that node operators had to adopt, not through a protocol-level authority. source
No central team (Source)	10	No central team: signum-node is maintained by volunteer community developers in the signum-network GitHub organisation (GPL-3.0); no company or foundation controls it. source

Protocol level privacy (Keys not tied to an identity · Whitepaper §10)	10	Accounts are created from keys users generate themselves; transfers are validated by signature, with no identity condition in the protocol.
UTXO ledger (Separate outputs, change to a new address · Whitepaper §2, §9)	0	An account ledger: one running balance for each address, so the remainder stays at the sending address and its payments share one public history.

Multisig and time locks (Without a third party)	✓	Native escrow transactions with up to 10 signers, a required-signers threshold and a deadline action, enabled since the escrow start block.
Atomic swaps (With other chains)	✓	Smart contracts can express hash-locked, time-locked escrow.
Native DEX (Trades the coin itself, not a claim)	✓	Traded as itself, not as a wrapped token or a claim: an exchange in its own protocol (Asset Exchange order book (ask and bid order transaction types) in the protocol, from the Burst/NXT lineage).
Cross-chain messaging (Verified by the chain itself)	✗	No cross-chain feature in the protocol.
NFTs (Carried by the chain's rules)	✓	NFTs via smart contracts the nodes run, named among the node's features.

Exploit of the chain, 2026-05-19, flaw fixed (the security fix above)	✓	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. github.com

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). github.com github.com europe.signum.network

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.

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.

The work behind it

No source we can reach publishes a hashrate for Signum.

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 Signum

Signum is #216 among cryptocurrencies and #1701 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 1485 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).
