Mainnet is clean.
And it stays that way.

The summary does not replace the full text below.

§ 1

Scope

• These rules apply to all Mainnet domains – with any ending, including custom endings (e.g. .com .de .net .org .cp77 .berlin) – activated by cypherpunk2077.com as the registry: to the website under the domain, the mail for the domain and everything offered, linked or brokered through them. A new ending is reviewed together with its first activation; reserved endings are not assigned.
• By submitting a domain request, the requester accepts these rules. Notice and link appear before the Bitcoin invoice: in the chat, in the info panel of one’s own domain when renewing, and on the command line. This also applies to every renewal.
• Owners are responsible for their content. They host their sites themselves; no website content, no mail and no relay reside on the registry’s computers. Before activation, the registry checks only name, brand and payment – not content.
• Hidden hosting does not change responsibility. Sites are hosted hidden by default (onion service via the built-in Tor); nobody can see where they are located. The owner nevertheless remains responsible for their content, and all rules and measures apply unchanged – they act on the domain and the content, not on the location.
• The registry can deactivate and permanently revoke any activated domain. The measures in section 4 refer to exactly this.
• Key addresses (k….cp77) are switched off; there are no sites without activation.

§ 2

Principle

Mainnet is something good – not a place to spread filth.

Mainnet is encrypted, but it is not a lawless space. Whoever gets a domain gets a place in a shared, clean network. Domains that violate these rules can and will be deactivated and, where applicable, permanently revoked and closed.

§ 3

Prohibited content and activities

In each case, not only the content itself is prohibited, but also offering, selling, brokering, advertising and linking to it, and providing instructions for it – on the website, by mail under the domain or via redirects. What counts is the content, not its disguise (e.g. code words, “for research purposes only”, paywalls, hidden subpages).

Each category has a reason code. Exactly this code appears in the public log when a domain is deactivated or revoked because of it.

§ 4

Measures

The registry does not review content in advance. It acts upon a report or on its own suspicion (notice and action). Every measure is triggered in the admin panel, signed with the admin key and published as an entry in the public transparency log.

In addition:

• No refund in the event of violations – neither upon deactivation nor upon revocation, not even pro rata. Remaining points (section 11) are forfeited.
• Serious cases without prior warning: for category 3.2 (abuse-csam), revocation is immediate and without prior warning. In other serious cases as well (e.g. active phishing, malware, terrorism, human trafficking), the registry may deactivate and revoke without prior warning.
• Repeat offenders: if a domain has been revoked from an owner key, that owner key is blocked for new requests; new requests made with it are rejected with reject. For this purpose, the admin panel shows earlier deactivations of this key with every request.
• The registry cannot change or delete content (the zone is signed by the owner); it can only deactivate or revoke the domain and add content to the blocklist.
• Limits: blocks take effect in official Mainnet software and nodes. Modified or third-party software can continue to serve or display a blocked site, and an onion service of the owner keeps running even without the Mainnet name. Devices without a network connection only learn of a block when they next connect. The block is nevertheless visible to everyone in the log, and official nodes and search do not help to spread the content.

§ 5

Reporting

Channels:

• in the Mainnet Browser via the “Report page” button (menu ⋯ or the info field of the ◆ Mainnet badge). The report is sent encrypted and via Tor to cypherpunk2077.com. Only the details from the report window and the public identifier of the website version currently displayed are sent – no history, no cookies, no screenshot.
• via the chat on cypherpunk2077.com – without an account, via Tor if you wish (onion service),
• or within Mainnet to support@mainnet.com.

◆ support@mainnet.com · Mainnet only

Contents of a report:

1. the affected domain or address (e.g. mainnet://shop.de/seite),
2. the category from section 3 (reason code, if known),
3. a short description of what exactly violates the rules and where it can be found,
4. optional: the chat’s return code, if you wish to be informed of the outcome (in the browser: tick “I want to be informed of the outcome”).

• For category 3.2, do not send any images or files – only the address and a description. The report button in the browser never accepts attachments.
• Reports are stored without sender data and are never published.
• Abuse of the reporting channel (knowingly false reports, mass reports against competitors, harassment) is not processed; anyone who abuses the reporting channel may be blocked in the chat. If the abuse involves a domain owner, it counts as a violation of these rules.

§ 6

Appeal

• The owner may lodge an appeal against any measure (rejection, deactivation, revocation) within 14 days of the log entry via the chat on cypherpunk2077.com.
• The appeal names the domain and states why the measure is wrong. The owner identifies themselves with their domain key (e.g. a message signed with the SDK) – no key, no appeal.
• The registry decides and replies in the chat. The outcome is recorded in the log: successful appeal → unsuspend (or activation via register after a rejection); rejected appeal → the measure remains or becomes a revoke. A successful appeal against a revocation also removes the related entries from the content blocklist.
• If the content blocklist hits harmless content (e.g. an image that a revoked site had copied from a legal site), anyone affected can contact the registry via the chat; the registry removes the entry.
• Once the 14 days have expired, the measure is final.

§ 7

Transparency

• Every measure appears publicly and signed in the transparency log – with a reason code (section 10) and, optionally, a short public justification (field note, at most 280 characters).
• No personal data in the log: no names, IP addresses, mail addresses, transaction IDs and no information about reporters.
• The content blocklist is public and signed, but contains only one-way identifiers – no addresses, paths or content. It cannot be used to find blocked content.
• Log entries cannot be changed or deleted. Anyone can verify which domain was deactivated or revoked, when and why.

§ 8

Allowed and welcome

Mainnet is there for everything that is good and legal, for example:

• private sites and blogs
• legal shops and services
• associations, initiatives, projects
• art, music, photography, games (without pornography)
• journalism, research, opinion sites
• education, tutorials, knowledge collections
• open source and software projects
• communities, forums, meeting places

Criticism, satire and uncomfortable opinions are allowed, as long as they do not fall under section 3.

§ 9

Changes to the rules

• New versions receive a new version number and a date and are announced: on cypherpunk2077.com, in the chat and as a policy entry in the log with the hash of the text version.
• A new version applies to new requests immediately and to existing domains 30 days after the announcement.
• Anything criminal (sections 3.2 and 3.12) is always prohibited, regardless of any version.
• Earlier versions remain available to read (version 1 of 26 Oct 2026).

§ 10

Reason codes

These codes are available for selection in the admin panel and appear in the log field reason.

§ 11

Term, points and payment

• A domain costs €4.99 per year, the same for every ending. Payment is accepted in Bitcoin only.
• €4.99 = 500 points = exactly one year of term (until the same day and time in the following year, UTC). Points belong to exactly one domain; they are not a credit balance and are not paid out in money.
• Payments that differ from the invoice are converted into points, in proportion to the invoice amount: paying too little gives fewer points and thus a shorter term; paying too much gives more points and a longer term.
• Activation and crediting take place after review by the registry, usually within 24–48 hours of the payment being received. Activation is always done by hand.
• Renewing (topping up points): in the info panel of your own domain in the Mainnet Browser (signed with your own key file), with the command mainnet renew <domain>, or in the chat. New points are added to the existing term; topping up early costs nothing.
• Reminders are sent 5, 3 and 1 week before expiry by mail to the domain’s mailbox; your own node also shows them. Reminders never contain a payment link. The owner remains responsible for renewing in time.
• There is no refund in the event of violations (section 4).

§ 12

Short version for the chat

The registry sends this text in the chat with every domain request.

Mainnet is something good – not a place to spread filth. Forbidden are, among other things, pornography of any kind, depictions of child sexual abuse, drugs, weapons, fraud, malware, hate, exploitation, illegal gambling, pirated copies, counterfeits and everything else that is criminal. Domains that break these rules are deactivated and, where necessary, permanently revoked – without refund, and every measure is public in the log. With your request you accept the terms of use (version 2, as of 27 Oct 2026).

§ 13

Changes from version 1

The wording of version 1 of 26 Oct 2026 remains available to read. The prohibitions (section 3), the reason codes (section 10), the appeal period, the rule for repeat offenders and “no refund in the event of violations” are unchanged.

1. § 4 Deactivation: instead of “offline for everyone (≤ 1 minute)” now “blocked in all official Mainnet software; target ≤ 1 minute for devices that are online; modified software can ignore this”. Correspondingly for revocation: “no longer reachable through official Mainnet software”.
2. § 4 new: limits of blocks (modified software, onion services, devices without a network connection).
3. § 4 new: content blocklist after a revocation; § 6 extended by removal for harmless hits and after a successful appeal; § 7 extended by the public blocklist with one-way identifiers.
4. § 5 Reporting: “anonymously via the chat” → “without an account, via Tor if you wish”; “reporters remain anonymous” → “reports are stored without sender data and are never published”.
5. § 5 new: “Report page” button in the Mainnet Browser, stating what is sent and what is not.
6. § 1: every custom ending included; rules are also accepted when renewing in the info panel and on the command line; hidden hosting does not change the owner’s responsibility.
7. § 2: “private and encrypted” → “encrypted”.
8. § 11 new: term, points and payment (500 points = 1 year, conversion of differing payments, usually 24–48 hours until activation, renewing, reminders); § 4: remaining points are forfeited in the event of violations.
9. § 9: reference to version 1, which remains available to read.

Version 2 applies to new requests from its announcement and to existing domains 30 days thereafter (section 9).
