* WIP - split the key in final tx step store "offset" on transaction itself * rebase * commit * tx with offset * got a test tx validating successfully using a sig from a split key and the appropriate offset * sum up the offset for the block_header * fix size tests for blocks and compact blocks (header now includes offset) * use txs with offsets in most of the core tests some tests now failing * build kernel from k1G (k2 stored on tx, sum stored on header) * commit * tx now has vec of kernels rework tx and kernel validation * add test for tx cut_through * wip - working on splitting in aggsig * split the key when creating the initial sender aggsig context * cleanup * cleanup * code needs claning up but split keys working for sender/receiver aggsig flow * cleanup debug logging * fix tests * fix merge and basic cleanup * fix keychain tests to use new tx_id
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.

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.
