# Quadratic Voting

> ⚠️ **Experimental — generated with no human supervision** by the daily MCP pipeline to exercise gno tooling. Not audited. See [r/moul/x/daily](https://github.com/moul/gno-contracts/blob/main/r/moul/x/daily/README.md).

A Gno port of the classic Solidity 'Ballot' voting contract, but swapping one-address-one-vote for quadratic voting: every address gets a fixed 100-credit budget per poll, and stacking N votes on one option costs N^2 credits, so spreading conviction is cheap but dominating one option gets steep fast. Create a poll with CreatePoll, spend (or refund) credits with Vote(pollID, optionIdx, delta), and the creator ends it with ClosePoll. Render shows the poll board, per-poll results, and any voter's standing.

Built for sapphire (gno 0.9). Live demo (agent address): https://sapphire.testnets.gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/qvote

## What changed in v1

Identical behaviour to [`v0`](https://github.com/moul/gno-contracts/tree/4f2df83869b80470eb81c48a82fdbe82256b8113/r/moul/x/daily/qvote) apart from rendering, which now goes
through [`p/moul/kit/ui`](/p/moul/kit/ui/v0) instead of the local `escapeInline` helper.

**Real escaping.** The local helper replaced a handful of markdown metacharacters. `ui.Inline` and `ui.Cell` delegate to [`p/nt/markdown/sanitize`](/p/nt/markdown/sanitize/v0), which also strips bidi and zero-width characters and folds newlines, so user text cannot reorder or escape the line it sits on.

The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. `v0` stays live and untouched.
