Microblog Wall

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A public, append-only microblog for gno.land. Anyone can post a short message (up to 280 bytes); each post records the caller's address and the block height at which it was made. The Render view shows the wall newest-first, 20 posts per page, with total count and prev/next pagination driven by the render path.

• Realm path: gno.land/r/REPLACE_ADDR/microblog
• Gno version: 0.9 (sapphire)

API

• Post(cur realm, msg string) — crossing tx. Panics if msg is empty or longer than 280 bytes. Stores {author, msg, height}.
• Count() int — total number of posts.
• Render(path string) string — Markdown wall, newest-first, paginated.
