Beginning of a first pass at simple wallet functionalities so Grin can be used to author transactions. We introduce a receiving server, to be at least able to build coinbase outputs that can be used by the mining daemon. Present: * Coinbase receiving API. * Command to start the receiving server. * Beginning of a transaction sending command. * Improvements to the REST API abstractions to support the above. Still to do: * Change to the miner daemon to use the receiving server. * A command line sender. * API to receive any transaction (not just coinbase). * A command line receiver. Beyond that, HD derivation and seed generation are very simple so far and almost certainly insecure. Just for testing for now. |

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, aiming to stay as such.
- Follows the MimbleWimble protocol, which provides great anonymity and scaling characteristics.
- Cuckoo Cycle proof of work (at least to start with).
- Relatively fast block time (a minute or less, possibly decreasing as networks improve).
- Fixed block reward, both over time and in blocks (fees are not additive).
- Transaction fees are based on the number of UTXO created/destroyed and total transaction size.
- Smooth curve for difficulty adjustments.

Status
Grin is still an infant, much is left to be done and contributions are welcome (see below). Check our mailing list archives for the latest status.
Contributing
Find an area you can help with and do it. Open source is about collaboration and open participation. Try to make your code look like what already exists and submit a pull request. If you're looking for additional ideas, the code includes TODO comments for minor to major improvements. Grep is your friend.
Additional tests are rewarded with an immense amount of positive karma. So is documentation.

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 disrepect of others' ideas.
We believe in pull requests, data and scientific research. We do not believe in unfounded beliefs.
