less chatty Testnet1 outputs (#316)
Fixes #281 by doing:

- "Starting validation pipeline for " -> "Processing "
- stdout logging default = Warning
- ERR -> INFO for "Transaction rejected: Already in pool" -- only for netadapter transaction_received, which (hopefully!) only gets tx from peers, and lots of those will be duplicates, that's good and not an error.

* Downgrade ERR even down to DEBUG.

Also let Transaction rejected show tx hash,
 so users can check if such a rejection is for the
 payment they expected, or just any random peer
 sending in some old and already known tx.

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.
