Fix pruning of last PMMR leaf, additional tests 
Due to the construction of PMMRs the last element, when its a leaf,
can never be pruned as it has no parent yet and it will be needed
to calculate that hash. To work around this, we now insert coinbase
outputs first to add at least one output of padding.

Also changed the `set_sumtree_root` function on chain a bit to allow
setting the roots on a fork. Mostly useful for tests.

Added new test case to handle both the issue above and spending
transactions within a fork.

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.

To learn more, read our introduction to MimbleWimble and Grin.

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.

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.
