# DGF Prototype
Decentralized Governance Framework

## Project Architecture

| directory | description |
| --------- | ----------- |
| ethereum  | Solidity smart contracts and associated deploy scripts |
| backend   | Node.js application with an HTTP API that also functions as a Matrix bot and Ethereum client |
| frontend  | React.js frontend with a WebApp route and a Matrix Widget route |

## Rollup

Instead of calling `DAO.initiateValidationPool()`, a contract can call `Rollup.addItem()`.

We demonstrate this by extending our base `Work` contract as `RollableWork`.

Our work contract normally triggeres a validation pool when the customer submits work approval. Instead, the fee and worker availability stakes are transferred to the `Rollup` contract.

The `Rollup` contract itself uses the `Availability` contract to assign a batch worker. This worker is responsible for making sure off-chain pools are conducted.

When ready, the worker submits the current batch on-chain by calling `DAO.addPost()` to create a batch post and then calling `Rollup.submitBatch()`, which initiates a validation pool targeting the batch post.
