Zecnero Brand and Press Kit

Using this kit

Most of what people want to do with the Zecnero name and marks is already permitted. This section is the short version; section 15 is the long one.

You may do all of this without asking

• Say that you support, list, mine, pool, index, wrap, integrate or write about Zecnero.
• Use the coin mark and the wordmark, unmodified, to refer to the project.
• Put the mark on a pool page, an exchange listing, a wallet, a block explorer, a chart, a news article, a conference slide or a comparison table.
• Ship the mark inside software that talks to the network.
• Redistribute this kit whole.

Ask first for these

• Using the name or mark in your product name, company name, domain or app-store listing.
• Merchandise you sell.
• Anything that could read as Zecnero endorsing, auditing or partnering with you.
• Anything where the mark appears larger or more prominent than your own.

The project

One paragraph, then the numbers. Both are cleared for reuse verbatim.

Chain facts

The founder stream is the figure most often reported wrongly. Both numbers are correct and they describe the same thing: 3% of each block subsidy during the first halving era, which works out to 1.5% of all ZMR that will ever exist. Do not add them together.

Naming and writing

The name is Zecnero. It is pronounced zek-NAIR-oh.

Sentences that are accurate

• Zecnero is a fork of Zcash with RandomX proof of work.
• Zecnero keeps Zcash's shielded transaction system.
• Zecnero has no premine and no dev fund.
• Zecnero is pre-testnet. No public network exists yet.

Sentences that are not

• "Zecnero is a Monero fork." It uses Monero's proof of work. Its code comes from Zcash.
• "Zecnero is a privacy layer for Zcash." It is a separate chain with its own coin.
• "Zecnero has launched." It has not.
• "Zecnero is backed by the Zcash Foundation." It is not affiliated with anyone.
• "ZMR is trading at …" There is no market.

The coin mark

A disc split on a diagonal, with a ticked Z laid across the split. The diagonal is called the seam, and it is the one element every other piece of the identity is built from.

Geometry

The seam runs from upper right to lower left. In the mark's own 1000-unit square it travels 1136 units horizontally for every 1248 vertically, which is 47.69° from the horizontal, or a run of 0.9103 per unit of height. Every cut corner, every angled panel edge and every wedge in the system uses that same angle. Nothing in the identity is set at 45°, and the difference is visible when the two sit side by side.

Clear space

Keep clear space equal to 25% of the coin's diameter on all four sides. Nothing enters it: no type, no rules, no other logos, no page edge. This is the one measurement in this document with no tolerance.

Minimum sizes

Below 32 px the charcoal half and the Night ground start to merge on low-contrast displays. At 24 px and under, use the one-colour version, where the Z and the seam are knocked out of a solid shape.

Backgrounds

• Night, black or any dark ground. Use the full-colour mark.
• White or light grounds. Use the full-colour mark. It was drawn to hold on both.
• Seam Orange. Use the one-colour mark in Night or White. Never the full-colour mark, because its own orange disappears.
• Photography or a busy pattern. Use the one-colour mark on a solid Night plate. Do not place the mark directly on an image.

The wordmark

ZECNERO is drawn, not typed. Seven letters cut from a geometric construction with a stroke of 40 units on a cap height of 200, and corners chamfered at the seam angle.

When to use it

• Headers, banners, covers, conference slides, merchandise.
• Anywhere the coin alone would not name the project.

When not to

• Never as a typeface. It is a logo with seven letters in it. Do not set other words in these letterforms, including repository names, headings or product names. Chakra Petch is the display face for that.
• Never re-typed in a font. It is vector artwork. Use the supplied files.
• Never letterspaced, condensed, stretched or re-weighted.

Supplied in white, black, and Seam Orange over Charcoal. The split colouring, where ZEC is orange and NERO is grey, exists because the name joins two parent projects. Use it on dark grounds only.

Lockups

Three approved arrangements. Do not build a fourth.

In the horizontal lockup the coin and the wordmark share a vertical centre line. The wordmark's cap height is 1/1.9 of the coin's diameter, and the gap between them is 0.37 of the coin's diameter. Do not adjust either ratio to fit a space; scale the whole lockup.

Avatars and repository banners

The project's own repositories use a derived system. It is documented here so third-party tooling can match it, and because it shows how the seam is meant to be extended.

Avatars

A square tile, the seam at the brand angle, Seam Orange above it and Charcoal below, never reversed. A single letter in the ZECNERO alphabet sits across the seam in white at a cap height of half the tile. How far the seam has slid encodes a tier: things a person runs are mostly orange, libraries and test data are mostly charcoal.

Banners

1200 × 300 at 1×, supplied at 2×. Night ground, corners cut at the seam angle, the coin at 156 units on the left, the repository name in Chakra Petch Bold at one size across the whole set, and a tag chip right-aligned at x = 866. The chip is filled orange for something you run and outlined orange for a library.

The name size is computed from the longest name in the set so every banner matches. Adding a longer name reflows all of them rather than shrinking one.

Colour

Four values. There is no secondary palette, no tint ramp and no semantic green or red. If a design needs more colour than this, it needs less colour.

No Pantone or spot colour is specified. For spot printing, match to the hex on a calibrated proof rather than to a swatch book conversion, which pushes Seam Orange toward red. The CMYK build above is for coated stock.

Supporting greys

These are not brand colours. They exist so interfaces built on the palette have somewhere to put secondary text and hairlines.

Contrast

White on Seam Orange fails at body size. This is why the coin's Z is a large shape and why type on orange panels is set in Night. If you need small text on orange, set it in Night.

How much of each

Roughly 70% Night or Ink, 20% Charcoal and the greys, 8% White, 2% Seam Orange. Orange marks one thing per view. When everything is orange, the accent stops working and the layout reads as a warning.

Typography

Three families, all under the SIL Open Font License 1.1. You may download, embed, subset and ship them at no cost, including commercially.

Scale

A 1.25 ratio from a 16 px base, rounded to whole pixels. Stay on the scale.

Rules

• Running text stays near 65 characters a line, never past 80.
• Numbers that line up in a column get font-variant-numeric: tabular-nums.
• Amounts, hashes, addresses and ports are always mono, even inside body copy.
• No italics anywhere in the system. No underlines except on links.
• If none of the three families is available, fall back to the system UI sans. Do not substitute another display face for Chakra Petch.

Grid, spacing and margins

One base unit, one spacing scale, and a stated tolerance for each measurement so that "close enough" has a number attached to it.

Base unit

Everything is a multiple of 4 px. The scale is 4, 8, 12, 16, 24, 32, 48, 64, 96, 128. Values off the scale are a mistake, not a decision.

Margins and gutters

Where a tolerance is given, it is there for optical correction, not for convenience. A 3 px nudge to make two shapes look aligned is the intended use. A 3 px nudge because a number was inconvenient is not.

The cut corner

Panels, chips and buttons cut their top-left and bottom-right corners at the seam angle. Never the other two, and never a radius. The cut length scales with the element:

Where a card carries an accent, the bottom-right cut edge is stroked in Seam Orange at 6 units and the top-left in Charcoal. The stroke goes on the cut itself, not around the whole shape.

The seam as a graphic element

• Always 47.69° from horizontal, running upper right to lower left.
• Never rotated, mirrored or reversed.
• On a banner it runs off the edge. It does not stop inside the frame.
• Never across a chart, a table or a block of text. It reads as a scratch on the artwork. Keep it in the empty margin of a composition.
• One seam per composition.

Misuse

Each of these has happened. None of them is permitted.

Also not permitted

• Adding a drop shadow, glow, bevel, gradient or outline to the mark.
• Placing the mark inside another shape, badge or container it did not ship in.
• Using the coin as a bullet, a list marker or a background watermark behind text.
• Animating the mark so that the seam moves or the halves separate.
• Combining the mark with another logo into a single composite.
• Using the mark as a favicon for a site that is not about Zecnero.

For mining pools

You do not need permission to run a pool, list the coin or use the mark on your site. These are the things worth getting right.

Technical

Things that will bite you

• Payouts to shielded addresses. Support them. A pool that can only pay to transparent addresses pushes every one of its miners into the public pool, which defeats the point of the chain.
• The encrypted memo is a field, not a tag. Use it to tie a payment to an account. Do not ask miners to put an identifier in a public field.
• Monero's RandomX will not work. The Argon2 salt differs, which yields an unrelated cache, dataset and hash function. Build against randomx-zecnero, and verify against the 17 published test vectors before you take a single share.
• Confirmations. Nodes refuse reorganisations deeper than 20 blocks, so 20 is a hard ceiling on what a reorg can undo. Choose your own crediting depth with that in mind.

Listing copy you may paste

CopyZecnero (ZMR) — rx/zecnero

No premine, no presale, no dev fund. 75 s blocks. 8 decimals.
Shielded payouts supported. Status: pre-testnet, no mainnet yet.

For news outlets

You may report on Zecnero, quote this kit, and use the marks in editorial context without asking. Corrections and questions go to the press address in section 18.

Boilerplate

CopyZecnero is a fork of the Zcash protocol that replaces Equihash
with RandomX, the CPU-oriented proof of work used by Monero, so
that ordinary desktop processors can mine competitively. It keeps
Zcash's Sapling and Orchard shielded transaction pools. The project
launches with no premine, no presale and no development fund; a
founder stream takes 3% of each block subsidy and ends permanently
at the first halving, totalling 1.5% of the 20,999,993 ZMR supply.
The software is open source under MIT or Apache-2.0. As of
publication no Zecnero network exists and no launch date has been
announced.

Attribution

Please do not report

• A price, market cap, volume or valuation. There is no market and no coin in circulation.
• A launch date. None has been set. When one is, it is announced at least a week ahead.
• An affiliation. Zecnero is not affiliated with, endorsed by or connected to the Zcash Foundation, Electric Coin Company, the Monero Project, XMRig or any other project whose work it builds on.
• A team. There is one maintainer and no staff.
• A token on another chain. Any asset called Zecnero or ZMR on Ethereum, Solana, BNB Chain or anywhere else is unrelated to this project.

Machine-readable copies

The download kit ships facts.json with the block above, and llms.txt with a plain-text summary in the convention crawlers look for at the site root.

Trademark policy

The software is open source. The name and the marks are not the same thing as the software, and this section says what you may do with them.

What is claimed

The project asserts common-law rights in the name Zecnero, the ticker ZMR, the coin mark and the ZECNERO wordmark. No registration is held in any jurisdiction at the time of writing. These marks are used to identify this project and no other.

Licence granted to you

You are granted a worldwide, royalty-free, non-exclusive, revocable licence to use the marks as supplied, without modification, for the purposes set out below, for as long as you comply with this policy.

Permitted without asking

• Nominative use. Using the name to refer truthfully to the project, including in comparisons, reviews, critiques and news.
• Support and compatibility. Stating that your product, pool, exchange, wallet, explorer or service supports, lists or is compatible with Zecnero.
• Unmodified marks in the contexts above, at any size at or above the minimums in section 04.
• Redistribution of this kit in whole and unaltered.
• Community use. User groups, meetups, forums, subreddits, wikis and fan sites, provided they do not present themselves as official.
• Academic and editorial use of any kind.

Requires written permission

• Use of the name or marks in a product name, service name, company name, domain name, social handle or app-store listing.
• Merchandise offered for sale.
• Any composite lockup joining a Zecnero mark to another mark.
• Any use implying endorsement, certification, audit, partnership or official status.
• Use of a modified mark, including recolours, for a technical reason such as a single-colour process.

Never permitted

• Use on, or in promotion of, an investment product, a token sale, a presale, a yield or staking product, or anything promising a financial return.
• Use on a token, coin or asset on any chain other than Zecnero's own.
• Use in a way likely to mislead a reasonable person into thinking your thing is the official thing.
• Use alongside content that is unlawful, or that promotes violence or hatred.
• Registration of the marks, or anything confusingly similar, as your own trademark, domain or handle.

Conditions on any permitted use

1. Use the files as supplied. Do not redraw, recolour, rotate, stretch or recompose.
2. Respect clear space and the minimum sizes.
3. Your own branding must be at least as prominent as Zecnero's.
4. Do not use the marks as the most prominent element on a page that is not about Zecnero.
5. Where reasonable, include an attribution line: "Zecnero and the Zecnero logo are marks of the Zecnero project."

Revocation

This licence may be revoked from any user, at any time, for any breach of this policy. Notice will be given to the contact address available, and a reasonable period allowed to correct the use before any further step is taken. Good-faith mistakes are expected and are resolved by correcting them.

Changes

This policy may change. Changes are not retroactive: a use that complied with the version in force when it began remains permitted for a reasonable transition period of no less than 90 days. Each version of this kit carries a version number and a date.

Governing law

Not yet specified. A governing-law and jurisdiction clause should be added by counsel before this policy is relied upon commercially.

Software and asset licences

Disclaimers

No investment

Nothing published by this project is financial, investment, tax or legal advice. ZMR is not offered for sale, has no price, and confers no ownership, revenue share, dividend, governance right or claim on anything or anyone. Nobody involved promises that a network will ever launch, that it will have value, or that it will keep running.

No warranty

The software is provided as is, without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. To the maximum extent permitted by law, no contributor is liable for any claim, damage, loss of funds or other liability arising from the software or its use.

Pre-release status

As of version 1.0 of this kit, Zecnero is pre-testnet. No public network exists. The node cannot join or mine any public chain. Consensus code has not had external security review. Anyone describing Zecnero as live, launched, tradeable or production-ready is wrong.

Regulatory

Privacy-preserving cryptocurrencies are restricted or face delisting pressure in several jurisdictions. Whether you may lawfully run, mine, hold, list or build on Zecnero depends on where you are, and it is your responsibility to find out. The project does not offer a view on any jurisdiction.

Mining

Hashrate earns a share of blocks and nothing more. No return is promised or implied. Nobody should buy hardware to mine this. Mining consumes electricity and shortens the life of the equipment doing it.

Security

A new chain has little hashrate, which makes majority attacks cheap until it grows. CPU-friendly proof of work suits botnets and stolen cloud accounts as readily as it suits honest miners. The project states these risks in its own documentation and does not consider them solved.
