guestbook/v0 package

Overview

Package guestbook is a public, on-chain guestbook realm for gno.land.

Anyone can sign the guestbook with a short message via the Sign crossing function. Every entry records the caller's address, the message, and the block height at which it was signed. Render lists all entries newest-first as a Markdown table.

Function

Sign

func Sign(cur realm, message string)
Ask AI Claude ChatGPT

Sign appends a new entry to the guestbook attributed to the immediate caller.

It is a crossing function (gno 0.9 interrealm convention): callers invoke it as Sign(cross(cur), "hello"). The cur.IsCurrent() guard is the authentication primitive — without it a stale/forged realm value could spoof the author.

Param

Command

# WARNING: This command is running in an INSECURE mode.
# It is strongly recommended to use a hardware device for signing
# and avoid trusting any computer connected to the internet,
# as your private keys could be exposed.
