If you want to create a world

The choices you can never change#

A worldA bounded shared story with a fixed number of paths and a known ending. is created by one transaction, and what it says is what the world is. There is no settings page later.

The title accepts letters, digits, spaces and the characters . _ : -. Nothing else, and no second chance. This is a name, not a description.

The lifetime counts from the block heightThe number of the block a transaction was confirmed in. your creation confirms in. When the chain reaches that height plus the duration, the world expires and every live path expires with it, finished or not. Choose a length you can hold people's attention across.

Writing an invitation people answer#

The chain holds 32 characters of title and a few very small numbers. Everything that makes people want to join (the prompt, the rhythm, the reason) lives outside it. Write that first, before you spend anything.

A good invitation says four things plainly:

• What one step means here. "One photograph from the walk." "One chord." Vague briefs produce vague worlds.
• The rhythm. Once a week for six weeks reads very differently from whenever you like.
• When it ends, in dates. Translate the block count into a real day and say it.
• What it costs the person answering. A miner fee plus 1,000 satoshis held in their carrierThe single small Bitcoin output that holds a path in place. while their path is alive, returned when they finish it. Say this before they arrive, not at the signing screen.

Looking after the people who answer#

You are not an administrator here. You cannot remove a step, edit a moment, or take a path back. Once a block confirms it, it is part of the world for good. Your influence is all front-loaded, so the guest list and the brief are the moderation. Moderation and privacy covers that in full.

What is left is the ordinary hosting work:

• Publish the world id and the path list somewhere permanent. Paths are numbered from 0, and a path id reads <worldId>:<laneNumber>. Without that list, nobody can find their own thread. There is no public index to look them up in yet.
• Warn people about the carrier. No wallet protects it today. If someone sweeps it by accident their path is abandoned and stays that way.
• Plan for silence. Someone will go quiet. Decide in advance whether that path is left open as part of the record or completed by its holder, and say so at the start.
• Help people meetOne transaction where two paths share a moment and both continue.. When two paths meet, one transaction spends both carriers, so both holders sign the same transaction. That takes coordination: a time, a channel, a person who nudges.
