BitGrin is a implementation of MimbleWimble with time tested Bitcoin economics.
This means there will only ever be 21 000 000 total coins, reducing block reward every 4 years.
There will be only 21 000 000 BitGrin forever, period.

BitGrin uses a very lightweight implementation of MimbleWimble, allowing every user to have complete privacy and anonymity. BitGrin is also very scalable thanks to our implementation of MimbleWimble we can achieve 60sec blocks while maintaining a lightweight blockchain.
BitGrin was built to follow the time-tested bitcoin economics to the letter, the max coin supply is 21 000 000. We added a flat-rate of 1BitGrin to be sent to developer wallets- effectively removing them from circulation- for the first 1 000 000 blocks, to closely imitate the economic circumstance of “satoshis coins”
BitGrin blockchain code, mining software code etc. Is completely open. This is an Open Source project, we encourage everyone to contribute and improve the code base, we also encourage every 3rd party in our ecosystem to do the same. Sharing is caring.
To ensure a fair launch BitGrin comes out with a “one-click” miner, so even non-technical users can immediately mine it and contribute in the economy.
