* Clean server shutdown, generalizes usage of `Weak`. Introduces 2 main changes: * A shared `AtomicBool` that signals server shutdown. All server threads regularly check it to break out of their main loops when it changes to `true`. * Breaking of circular `Arc` references, which can never be destroyed, by downgrading to `Weak` instead. Only the main server keeps the `Arc` while all other components get the `Weak` variant. Both of these are required for all long-living structs to be cleanly destroyed. Note that in Rust this is fairly important as most resource-freeing logic is associated with `drop`, which is only called when said struct is free of scope or `Arc` references. Should address most of #536 (only need the stop hook to call `Server` shutdown). * Test for fast sync, followed by restart, followed by re-fast-sync * P2P test fix * Double sync taking too long for Travis, commenting out for now
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.

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.

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.
