Merge pull request #83 from poanetwork/afck-observer 
Allow observer nodes in all algorithms.
 2018-06-26 15:12:46 +02:00

Andreas Fackler 2a5f9f1bfe Allow observer nodes in all algorithms. 
This allows nodes to join the network without sending any messages
themselves. They can't give any input and just observe the outcome.

Closes #81

Andreas Fackler 062b35ab3a Make SyncKeyGen NodeUid-aware. 
This allows the caller to address nodes by ID instead of by index.

Also contains a few other minor changes that will be needed for
`DynamicHoneyBadger`.

Andreas Fackler e11f183db2 Remove generic E: Engine from crypto. 2018-06-22 10:08:23 +02:00
Andreas Fackler 7eb487f329 Implement SyncKeyGen. 
This is a _synchronous_ key generation algorithm. We will use it in
`DynamicHoneyBadger`, on top of `HoneyBadger` to satisfy the synchrony
requirements.

It can also be used independently e.g. on top of a blockchain.
 2018-06-22 10:06:29 +02:00
