Nexa (NEXA)
Nexa ranks #186 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1356: 1170 of the 1355 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 1602 non-native assets CoinSpectrum lists above it by market cap, about 61% are tokens, 32% are claims on other assets, 6% are memecoins and 1% are NFT collections.

A — 67 out of 100, provisional (from 10 of 10 sections, 10 November 2026 build). With what is not yet measured anywhere from nothing to full marks, the score would be 58 to 69 (B to A).

| Features (3 checks) | 10 | 3 of 3 passed |
| Fast payments (Safe to accept within seconds · Whitepaper abstract, §1, §2 and §11) | ✓ | The nexad node (Bitcoin Unlimited lineage) relays first-seen transactions and has no replace-by-fee, so zero-confirmation payments are protected by network relay policy. |
| Pruned nodes (Old history dropped, every rule checked · Whitepaper §7) | ✓ | Nexa node (Bitcoin Unlimited lineage) keeps the -prune option. |
| Light clients (Payments verified from headers · Whitepaper §8) | ✓ | Bitcoin-style SPV: block headers plus Merkle-branch proofs (BIP37 merkleblock) served by full nodes. |
| Adaptive block size (a bonus point, at most 10) | +1 | Maximum block size is ten times the larger of the 90-day and 365-day median block sizes, with a 2 MB floor (100 kB before the March 2025 fork) and a 1 GB ceiling; in consensus since launch. |
| 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 | Addresses are hashes of keys users generate themselves; the node checks scripts and signatures, with no identity condition in its consensus rules. |
| 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 UTXO amounts; no confidential-transaction or shielded feature. |
| Hidden parties (Sender and receiver hidden) | 0 | Transparent addresses; no ring signatures, ZK proofs or stealth addresses. |
| Network privacy (Origin hidden by default) | 0 | Bitcoin-derived node relays its own transactions over clearnet by default; Tor (-proxy/-onion) needs user setup and there is no Dandelion. |
| Programmability | 6.7 | 6 of 9 points source |
| Token issuance (At protocol level) | 2 | Group tokens are native consensus rules since mainnet launch in 2022, letting any address create fungible tokens and NFTs. |
| Smart contracts (Scripting for spending conditions) | 1 | Nexa Script with transaction introspection (OP_PUSH_TX_STATE), OP_EXEC and pay-to-template contracts since the 2022 mainnet, but no DEX, lending or similar applications running on it were found, so it is scored as spending-condition script; low confidence. |
| Multisig and time locks (Without a third party) | ✓ | OP_CHECKMULTISIG, OP_CHECKLOCKTIMEVERIFY and OP_CHECKSEQUENCEVERIFY in its script interpreter; the spec documents a time-lock vault contract. |
| Atomic swaps (With other chains) | ✓ | Script can express HTLCs (hash check plus CLTV/CSV refund). |
| 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) | ✗ | No cross-chain feature in the protocol. |
| NFTs (Carried by the chain's rules) | ✓ | Group tokens in the consensus rules since the 2022 mainnet, with an NFT/SFT specification built on group subgroups. |

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.

5,859,620,000,000 of a maximum 21,000,000,000,000 NEXA are in circulation — 27.9% of the total that will ever exist.
Launch and allocation
| Premine (allocated at launch) | 0% of today's supply |
|---|---|
| Sold by the issuer or insiders | 0% of today's supply |
| Developer share received since launch | 0% of today's supply |
| Developer share of new coins today | 0% |
| Fundraising | No sale and no investor round |
Launched 21 June 2022 by the Bitcoin Unlimited team with no premine, no ICO and no developer or organisation carve-out; all coins are mined.
No sale, ICO or venture allocation.
No cut. All 10M NEXA per block goes to miners; there is no developer fund or treasury share.
The no-premine claim comes from project and secondary sources and wasn't checked against the genesis block. Supply figures disagree widely: CMC shows 5.86T circulating, CoinGecko 11.13T. The reward schedule (10M NEXA per block) supports CoinGecko's figure.

The work behind it
Nexa is secured by 1.88 TH/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 Nexa
Nexa is #186 among cryptocurrencies and #1356 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 1170 places between Nexa'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).
