This is a Polkadot treasury proposal by Centrifuge to fund the development of FUDGE (FUlly Decoupled Generic Environment for substrate-based chains). FUDGE provides a simple and generic way to interact with and manipulate the database of a substrate-based blockchain. This includes building and importing blocks locally without any kind of network or consensus, as also changing existing state and finalizing it without the need of forging a new block.
The currently most obvious use-case for FUDGE are local integration tests as the library drastically reduces time and overhead for these. But the library is furthermore useful as a core building block around clis in the Substrate ecosystem. E.g. a cli for forking-off a database of a node, tooling around analysing a chain in various states (i.e. at variaous blocks).
There already exists a PoC version of the library (https://github.com/centrifuge/fudge) and the library is actively used by the Centrifuge team for integration tests (https://github.com/centrifuge/centrifuge-chain/tree/main/runtime/integration-tests).
