Not for production.** Full context & folder README: > [r/moul/x/daily](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md) --- A multi-author on-chain blog realm for gno.land. Anyone can publish a post; each post records its author (the calling address) and the block height at which it was published. Posts are stored persistently and rendered newest-first, with a dedicated page for each post's full text. **Realm path:** `gno.land/r/REPLACE_ADDR/blog` ## Example calls Publish a post (state-mutating, crossing function): ``` gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/blog" \ -func Publish -args "My first post" -args "Hello, gno.land!" \ -gas-fee 1000000ugnot -gas-wanted 2000000 -broadcast -chainid sapphire-1 KEY ``` Read views (no transaction needed): - Root — list all posts, newest first: render `gno.land/r/REPLACE_ADDR/blog` - Single post by id: render `gno.land/r/REPLACE_ADDR/blog:/0` `PostCount()` returns the total number of published posts. <!-- BEGIN GNOCONTRACTS FOOTER (generated by `make readmes`; do not edit below) --> --- Part of **[moul/gno-contracts](https://github.com/moul/gno-contracts)** — moul's versioned gno.land contracts.
