Here is a basic roadmap I have in my head, aided by github. This not speaking for the founders or the project. Perhaps it can serve as a starting point for a official-ish roadmap.
In progress
- Succinctness – a major differentiator for Neptune Cash
- Proof of Reserves
- Faster Utxo Scanning
- Faster Syncing
- Speed up Large Wallets
- Security Fixes
- Support Wallets outside neptune-core
- Calc available supply
on the drawing board
- Mempool transaction chaining
- Crowdfunding smart contract (CCS)
- Standards for building UTXO based Smart Contracts
- Outsourcing Proof Generation for Weak Devices
- Paper Wallet Generator
Future
- Light Node Library – For building light nodes / wallets requires succinctness.
- Mobile Wallets – served by neptune-core full node
- Light Node Wallets – connecting directly to neptune p2p network.
- Non-native tokens – define standards, wallet support, etc.
- various Defi stuff.
- L2 wizardry
- Perhaps a neptune native DEX.
- Open Source GPU miner
