* rework bucket txs * introduce max_block_weight to global (based on chain_type) not yet in use anywhere... * now using global::max_block_weight() everywhere * testing max_block_weight needs to be big enough to cover existing chain tests... * add some test coverage for prepare mineable transactions at the block weight limit introduce AsLimitedTx{max_weight} so we can build artifically small blocks (per mining config) * cleanup * default_mineable_max_weight is just the default max_block_weight we do not need to account for coinbase reward here (tx vs block) * 75 change outputs in a test is not valid now that we have a low block weight limit... |

Grin
Grin is an in-progress implementation of the MimbleWimble protocol. 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 great anonymity and scaling characteristics.
- Cuckoo Cycle proof of work in two variants named Cuckaroo (ASIC-resistant) and Cuckatoo (ASIC-targeted).
- Relatively fast block time: one minute.
- Fixed block reward over time with a decreasing dilution.
- Transaction fees are based on the number of Outputs created/destroyed and total transaction size.
- Smooth curve for difficulty adjustments.
To learn more, read our introduction to MimbleWimble and Grin.
Status
Grin is live with mainnet. Still, much is left to be done and contributions are welcome (see below). Check our mailing list archives for the latest status.

Getting Started
To learn more about the technology, read our introduction.
To build and try out Grin, see the build docs.
Philosophy
Grin likes itself small and easy on the eyes. It wants to be inclusive and welcoming for all walks of life, without judgement. Grin is terribly ambitious, but not at the detriment of others, rather to further us all. It may have strong opinions to stay in line with its objectives, which doesn't mean disrespect of others' ideas.
We believe in pull requests, data and scientific research. We do not believe in unfounded beliefs.
