Minimal implementation of the Mimblewimble protocol.

* cleanup legacy "3 dot" check (#2625)
* Allow to peers behind NAT to get up to preferred_max connections (#2543)
Allow to peers behind NAT to get up to preffered_max connections
If peer has only outbound connections it's mot likely behind NAT and we should not stop it from getting more outbound connections
* Reduce usage of unwrap in p2p crate (#2627)
Also change store crate a bit
* Simplify (and fix) output_pos cleanup during chain compaction (#2609)
* expose leaf pos iterator
use it for various things in txhashset when iterating over outputs
* fix
* cleanup
* rebuild output_pos index (and clear it out first) when compacting the chain
* fixup tests
* refactor to match on (output, proof) tuple
* add comments to compact() to explain what is going on.
* get rid of some boxing around the leaf_set iterator
* cleanup
* [docs] Add switch commitment documentation (#2526)
* remove references to no-longer existing switch commitment hash
(as switch commitments were removed in

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.

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.
