![PixelProof.jpg](https://i.ibb.co/rGW7vXGK/Pixel-Proof.jpg)Apillon, in collaboration with Parity Technologies and R0gue, is proud to submit this proposal for **Pixelproof** — a fully decentralized, production-grade photo storage application built on the Polkadot ecosystem. Our goal is simple yet bold: to create the **first flagship consumer-facing dApp** on Polkadot that rivals mainstream solutions like Google Photos, but with **true user ownership, privacy, and decentralization** at its core.

Despite Polkadot’s maturity in infrastructure and protocol-level innovation, the ecosystem still lacks powerful, user-first applications that resonate beyond crypto-native circles. Pixelproof fills that gap.

Pixelproof is more than a technical showcase — it is a usable, polished, multi-platform application designed for everyday users. It leverages:

* **IPFS + Polkadot-native storage** via the Apillon SDK
* **Embedded wallet authentication** with no seed phrase friction
* **Smart contract-based access control and monetization** features
* **AI-powered content moderation and safety layers** using Umanitek
* **Phala Cloud deployment** for privacy-preserving self-hosted instances

This proposal outlines a **6–8 month development roadmap** with the total requested funding of **$575,000**, covering infrastructure, smart contract development, wallet integration, UX, DevOps, and open-source tooling.

We invite the Polkadot community to review the [full proposal PDF](https://bafybeic5xgz7lynqjqdl5leh6xf3pehixi55vuzaornkvvzrfing5kpob4.ipfs.web3approved.com/?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJjaWQiOiJiYWZ5YmVpYzV4Z3o3bHlucWpxZGw1bGVoNnhmM3BlaGl4aTU1dnV6YW9ybmt2dnpyZmluZzVrcG9iNCIsInByb2plY3RfdXVpZCI6IjRiZDI1NDZiLTY3MTQtNDU3Ni1hZTAxLWY4NmUxZWE5NjVlNiIsImlhdCI6MTc1MDg0Mzk3NCwic3ViIjoiSVBGUy10b2tlbiJ9.QJr2H4LcheK1sUkL38aejleQsi0Iz72o5kstE_6XOjk "full proposal PDF") for an in-depth breakdown of architecture, and the strategic value Pixelproof brings to the ecosystem.

Together, let’s show the world what a real Web3 app can look like.

Propose and approve a spend of treasury funds.

## Dispatch Origin

Must be [`Config::SpendOrigin`] with the `Success` value being at least
`amount` of `asset_kind` in the native asset. The amount of `asset_kind` is converted
for assertion using the [`Config::BalanceConverter`].

## Details

Create an approved spend for transferring a specific `amount` of `asset_kind` to a
designated beneficiary. The spend must be claimed using the `payout` dispatchable within
the [`Config::PayoutPeriod`].

### Parameters
- `asset_kind`: An indicator of the specific asset class to be spent.
- `amount`: The amount to be transferred from the treasury to the `beneficiary`.
- `beneficiary`: The beneficiary of the spend.
- `valid_from`: The block number from which the spend can be claimed. It can refer to
  the past if the resulting spend has not yet expired according to the
  [`Config::PayoutPeriod`]. If `None`, the spend can be claimed immediately after
  approval.

## Events

Emits [`Event::AssetSpendApproved`] if successful.
