BitcoinZ (BTCZ)

BTCZ price chart

BitcoinZ ranks #260 of 484 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #2325: 2065 of the 2324 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 2624 non-native assets CoinSpectrum lists above it by market cap, about 61% are tokens, 34% are claims on other assets, 4% are memecoins and 1% are NFT collections.

CoinSpectrum Grade (Source)

A — 71 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 63 to 72 (A to A).

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	7.3	the supply scale times 0.9, and a point for a fixed cap that holds
Supply (21 million scores 10)	7	fixed maximum supply of 21 billion
Distribution	9.8	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. Fair launch on 2017-09-09 as a Zcash-code fork without Zcash's founders' reward; no genesis allocation, ICO or instamine found. source
Fundraising (share sold) (Source)	10	No sale of the coin source
Developer share (after launch)	9.5	Developer share: about 4.6% of today's supply received so far; 20% of each new block reward goes to them today. A 5% 'community fee' to 2-of-3 multisig addresses from height 328,501 (2019-04-07) to 1,400,000 (2024-08-05), and since the Canopy upgrade at height 1,735,000 (2026-03-16) three ZIP-207 funding streams of 7%, 5% and 8% (20%) to BitcoinZ t3 addresses until height 3,360,000. Arithmetic: 511,500 x 625 + 560,000 x 312.5 + 127,198 x 625 = ~574M BTCZ / 12.60B supply = 4.6%. source
Decentralisation	10	average of 3 parts
Governance (Source)	10	No authority can halt the chain or freeze funds: No protocol key can freeze coins; the October 2026 rollback was carried out by a mandatory node release that miners and exchanges adopted, which is evidence of coordinated reversal rather than a standing power. source

Steady work, 6 of 6	✓	24 commits in 5 of the last 12 months (github.com/btcz/bitcoinz); BitcoinZ 2.3.1 (emergency) released 2026-10-21, after 2.3.0 (2026-10-19), 2.2.0 (2026-05-05), 2.1.1 (2025-08-14) and 2.1.0 (2024-10-14).
Shipped a security fix in two years, +1	✓	BitcoinZ 2.3.1 (emergency), Oct 2026: invalidated block 1,860,181, whose input-less transactions minted 105 billion BTCZ through skipped Sprout proofs and a 64-bit overflow, and disallowed JoinSplits.
Exploit of the chain, 2026-10-21, flaw fixed (the security fix above)	✓	Block 1,860,181 carried five input-less transactions spending Sprout JoinSplits with all-zero proofs, minting 105 billion BTCZ because cached checks skipped proof verification; BitcoinZ 2.3.1 invalidated the block and rolled the chain back. github.com

Unfixed vulnerability, disclosed 2024-07-03, −1	✗	CVE-2020-14198: misbehaving peers are auto-banned into an unbounded ban list, so many attacker addresses (cheap with IPv6) can exhaust memory; still in BitcoinZ 2.3.1. bitcoincore.org github.com github.com
Unfixed vulnerability, disclosed 2024-07-31, −1	✗	CVE-2024-52919: addr-message spam can overflow the address manager's 32-bit id counter and crash the node, with no addr rate limit; still in BitcoinZ 2.3.1. bitcoincore.org github.com

Not yet researched
Exploit of the chain, 2026-06-20, fix not yet recorded	–	Block 1,789,967 carried an input-less transaction spending a Sprout JoinSplit whose proof was never verified, minting about 56.3M BTCZ; the block was not invalidated. explorer.btcz.rocks github.com github.com
Conduct (origin, claims, halts)	9	2 positive, 1 negative source
Positive record
Launched with a stated purpose, not as a joke	✓
No claims by its founders that contradict its own design	✓
Negative record
Halt, freeze or reversal, 2026-10-21	✗	Block 1,860,181 contained five input-less Sprout JoinSplits with all-zero proofs creating 105 billion BTCZ that never existed. The developers' emergency release 2.3.1 declared it invalid and rewound the chain to 1,860,180, rolling back every later transaction; exchanges were told to keep deposits and withdrawals suspended. github.com

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.

Proof of Work coins

Proof of Stake coins

Supply

12,604,351,724 of a maximum 21,000,000,000 BTCZ are in circulation — 60.0% 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	4.6% of today's supply
Developer share of new coins today	20%
Fundraising	No sale and no investor round

Fair launch on 2017-09-09 as a Zcash-code fork without Zcash's founders' reward; no genesis allocation, ICO or instamine found.

Community-launched; no ICO, presale or investors.

No sale.

A 5% 'community fee' to 2-of-3 multisig addresses from height 328,501 (2019-04-07) to 1,400,000 (2024-08-05), and since the Canopy upgrade at height 1,735,000 (2026-03-16) three ZIP-207 funding streams of 7%, 5% and 8% (20%) to BitcoinZ t3 addresses until height 3,360,000. Arithmetic: 511,500 x 625 + 560,000 x 312.5 + 127,198 x 625 = ~574M BTCZ / 12.60B supply = 4.6%.

Two forged-proof incidents: on 2026-06-20 block 1,789,967 accepted a Sprout withdrawal with an unverified proof that paid 56,305,778 BTCZ to t1RGJarR9UVinsAVmH2Xxdw7sVW8oeSM6Kn. That block remains in the chain (issue #118; 2.3.1 checkpoints past it), and the Sprout pool held only 0.447 BTCZ afterwards. In October 2026, 105 billion counterfeit BTCZ were rolled back. zpool, a multipool, finds about 89% of blocks. The funding-stream labels (ECC, Zcash Foundation, Major Grants) are inherited from Zcash code; their recipients are BitcoinZ multisig addresses.

The work behind it

BitcoinZ is secured by 12 kH/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 BitcoinZ

BitcoinZ is #260 among cryptocurrencies and #2325 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 2065 places between BitcoinZ'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).
