Bitcoin MW is an implementation of the Mimblewimble protocol that maintains the Bitcoin (BTC) UTXO set with no pre-mine, dev fund, ICO or dev tax (i.e. 100% fair launch). Thus, it is a hard fork of Bitcoin. The Bitcoin UTXO set is installed into an entirely new application which adds privacy, improved scaling, and fungibility characteristics. Whenever there is a fork of Bitcoin, which side of the fork is "Bitcoin" is decided solely in the order book. As developers, we do not make that decision. We only choose which code to maintain. We believe this fork is worthy of our attention and leave it up to the holders of Bitcoin to decide where to assign value. Many characteristics are still undefined but the following constitutes a first set of choices:
- Clean and minimal implementation, and aiming to stay as such.
- Follows the Mimblewimble protocol, which provides hidden amounts and scaling advantages.
- NIT (Non-interactive transactions) to be more familiar to Bitcoin users.
- Memory bound, asic-resistant Cuckoo Cycle proof of work (C29d)
- Relatively fast block time: one minute.
- Bitcoin's limited supply schedule (starting with the 3.125 coins per 10 minutes epoch) with an extended long tail reward that lasts 1,000 years. Total supply cap is still 21 million.
- Transaction fees are based on the number of Outputs created/destroyed and total transaction size.
- Smooth curve for difficulty adjustments.
BitcoinMW's live with testnet. Launch of mainnet planned for early 2022.

BitcoinMW believes that the BTC utxo set and supply cap is sacrosanct. But, which code users run is open to debate. May the best implementation of Bitcoin win out.
