gno.land/r/moul/x/social/threads/v0

A discussion block any realm can embed, keyed on the page it appears on rather than on the realm that stores it. Two lines in the host realm, which stores nothing:

1import "gno.land/r/moul/x/social/threads/v0"
2
3func Render(path string) string {
4	return body + threads.RenderBlock()
5}

RenderBlock takes no argument because it does not need one. A plain read exported by a realm and called by another opens no realm frame, so unsafe.CurrentRealm() inside it reports the caller: the host realm's own path is the page key, and nothing has to be configured, registered or passed. RenderBlockFor(page) is the explicit form, for a realm that renders several pages or already holds its path as a constant. Adding a cur realm parameter to either would silently reverse that and key every embed to this realm.

It is the text half of r/moul/reactions: the same embed shape, the same page keys, and the same reason for existing.

The token, and the three things it has to answer

THREAD is a GRC20 issued through p/moul/x/social/coin, which refuses to create a token until all three of these are written down:

mint	1 THREAD to a thread's author, the first time each distinct address replies to it. People, not messages, and never yourself.
sink	Boost burns 10 THREAD to pin a thread to the top of its page for 1,000 blocks. It is the only thing that removes supply, and the only thing the token does.
buyer	anyone who wants placement and has not earned it. They have to acquire THREAD from somebody who did, with Transfer.

Placement is the one thing a discussion has that people want and cannot all have at once, which is what makes it a sink worth paying for rather than a leaderboard. A pin extends from whichever is later, now or the current pin, so buying one never shortens somebody else's, and Boost charges before it pins.

It is farmable, and saying so is cheaper than pretending otherwise: two addresses replying to each other mint one THREAD each per thread. The fix is a gate on who counts as a replier, which belongs in r/moul/x/social/vouch and not here. Until then the cost of farming is one transaction per point and the benefit is capped by what a pin is worth.

The token is registered with r/nt/grc20reg, so a realm that does not import this one can still find and move it by key: TokenKey() returns it.

Why this realm is not private

Every other realm in the x/social family is private = true and can be redeployed in place. This one cannot be, twice over: a private realm cannot be imported at all, which would delete the embed, and handing an object to another realm (registering the token) panics at runtime from a private realm. Every thread, balance and pin under this path belongs to the people who wrote them, so a fix ships as a v1 beside it rather than as a redeploy that wipes the lot.

Reading it

Render("") is the index: the counts, the recent threads across every page, the token's three declarations, and the embed snippet. Render("page/<page key>") is one page's threads, Render("thread/<id>") is one thread with its replies and the reply and boost buttons.
