Making Room For Litecoin

Although Grin++ was originally written to only support Grin, with a little bit of work, it could be made to support nearly any Mimblewimble-based coin out there. I expect the design to change significantly over time as I learn what works and what doesn't, but here is my initial plan for including support for LTC's MW Extension block:

The main GrinPlusPlus repo will be broken into 5 smaller repos:

1. Core

• Common (Logging, Utils, File I/O, Serialization, etc.)
• Crypto (Hashing, encryption, ECC, and ZKProofs)
• Crypto-related data models (BigInteger, Commitment, Committed, Hash, Hashable, Signature)
• Transaction Model (Transaction, TransactionBody, Input, Output, Kernel)
• MMRs (KernelMMR, OutputPMMR, RangeProofPMMR)
• Basic MW Validation & Utils (TxAggregation, Cut-Through, Transaction Validation, Kernel Sum Validation, etc.)

2. Database

3. Protocol

4. Node

5. Wallet
