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 classic Magic 8-Ball as a gno.land realm. Ask a yes/no question and the current **block height** picks one of the 20 canonical answers — fully deterministic, since there is no true randomness on-chain. - `Ask(cur realm, question string) string` — records `{caller, question, answer, height}` and returns the answer (crossing function; emits a `Shaken` event). - `Asked() int` — how many questions have been asked (read-only). - `Render(path string) string` — shows the last answer and a table of recent shakes. Built for the sapphire testnet (gno `0.9`). Example: ``` gnokey maketx call -pkgpath gno.land/r/moul/x/daily/eightball/v0 \ -func Ask -args "will this PR pass CI?" ... ``` <!-- 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.
