# Scope cut from original referendum
## Research Track
- UTXO analysis: While the UTXO analysis is important for showcasing the applicability of MMB in typical use cases, it is not essential for the initial preprint paper. We postpone this to the full MMB paper.
- Exploration budget: We postpone this to the full MMB paper.
- Increment proofs (Clojure PoC): not crucial for Polkadot/JAM deployment - only needed for slashing in bridges. We will implement this in a followup proposal.
## Implementation Track
- F-MMB: For Polkadot deployment, only one flavor of MMB is required, and we reckon that double-bagged MMB is the best contender for this.
- Increment proofs: not crucial for Polkadot/JAM deployment - only needed for slashing in bridges. We will implement this in a followup proposal.
