Nine missions written for nine billion people. The number of people building them can be counted on one hand.

That gap is nothing to be ashamed of — everything starts this way. It is simply the project's remaining central problem, and it has no technical solution.

A small group cannot keep a hundred-year promise

This document admits two things to you side by side. One: everything here was proposed by the founding group. Two: the founding group is only scaffolding, and the removal schedule is counted publicly.

Those two can only both be true if a third is: someone must step into the place the scaffolding is holding up. A network promising to outlive the people who wrote it must not depend on them. The invitation below is therefore not a courtesy — it is the condition that keeps the other promise from being empty.

Five ways to take part, and each one's door

Take part by…	What it means concretely	Door	Corresponding role
Contributing	Criticism. Find where this document overstates, misstates, or evades	OPEN	Citizen — reading and debating
Building	Contracts, applications, tools — and documentation, translation, teaching	AJAR — can be submitted through the channels; fully open when the public code repository is settled	Builder
Accompanying	Running an independent node, or an audit node, on your own infrastructure	NOT OPEN — awaiting participation artefacts	Signer · Witness
Governing	Proposing, debating, voting on everything labelled PROPOSED	NOT OPEN — awaiting distribution of voting power	Citizen — proposing and voting
Owning	One real human, one share, one vote	LEFT BLANK — how shares are received has not been designed	Tier A: Human

Read that table down the "Door" column and one thing is immediately visible: the deepest way to take part is the most tightly shut. That is the uncomfortable truth of this phase, and hiding it would turn the invitation into an advertisement.

Four things you can do now, without anyone's permission

1 · Find what is wrong in this document. It lists its own weak points in Open questions and concerns. If you find one that is not on those lists, that is the most valuable gift a stranger can give this project.

2 · Check the network yourself. Check the network yourself reads straight from public endpoints, through no number the project declares. The three questions there can be asked of any network, not only this one.

3 · Check the document yourself. The text is hashed and anchored to Bitcoin; the Verify this document page gives you the artefacts to reconcile with independent tools.

4 · Demand the three missing doors. They are listed below with the gate each must pass — so you can ask about the right thing instead of asking in general.

Two addresses, one purpose — feedback, criticism, and security reports: contact@9chain.org · t.me/LOVE_9Chain

Three doors the founding group still owes

Door still owed	The gate it must pass	Who walks in when it opens
Participation artefacts — genesis file, peer addresses, node image, configuration bundle	Ajar. The genesis file and peer addresses can now be read straight from public endpoints, and the project's technical site has a guide to running a full node — no keys, no tokens, no permission from anyone. What is missing is the configuration bundle and node image: the guide's first command points into a directory inside the unopened code repository ⇒ this door is locked to the one below it	Validator operators · customer-side operations teams · audit nodes
Public code repository and a contribution path	Settle the decision to open the code — contribution and open code go together; opening one without the other is meaningless	Builders — code, documentation, translation
Real voting power, outside the project's hands	Distribute stake to the point where the project loses its veto	Citizens — and only then does ratification carry legitimacy

These three doors are not on the ENGRAVED list. They are work to be done, and their progress is measurable from outside using the four-level ladder — no one's word required.

And one thing becomes clear on comparing this table with what the project has published: the first two doors are really one. However open a node guide is, it is no more open than the repository holding what it tells you to copy. While the code repository stays closed, the sentence "one machine, one command" is true for insiders and not yet true for outsiders — and outsiders are who that door was built for. The honest measure of the first door is therefore not "have the artefacts been published" but "can a stranger, with only what is public, actually raise a node".

What someone arriving later can still change

Finally, the sentence most worth saying on this page: the right to change the design has no deadline. Under the constitution, everything but the three memorial blocks belongs to the community's vote, for as long as the network lives. What has a deadline is the price of changing it: from now until the genesis of mainnet — through Testnet 1, 2 and 3 — everything labelled PROPOSED and LEFT BLANK can be edited on the drafting table: total supply, the release rhythm, the nine roles, how a human receives their share. After genesis it can still be changed — but it must win a vote on a living network, and the record can no longer be changed: what genesis did stays permanently in the ledger, and "permanently" in an infrastructure meant to live for centuries means longer than everyone reading this sentence.

So if you intend to say something about this project, the moment when saying it is cheapest and carries most weight is now, while it is still words.

In short: nine missions cannot be held by nine people. What this document invites you to is not a product to use, but a ledger to write together — and an invitation is only as true as the number of doors already open, so we list the closed ones too, with the name of who must open them: ourselves.
