Compaction of pruned data for chain data structures (#746) 
* Implementation of compaction for the chain. Single entry point on the chain triggers compaction of all MMRs as well as the cleanup of the positional index and full blocks.
* API endpoint, additional tests and more fixes for compaction
* Also prune PMMR metadata, minor bug fix
* PMMR store tests fix

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 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 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.
