Andreas Fackler 2db67df325 Rename is_full_node to is_peer. 2018-06-26 10:57:44 +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

Merge pull request #79 from poanetwork/afck-keygen-node-id 
Make SyncKeyGen NodeUid-aware.
 2018-06-25 15:46:22 +01:00
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 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.

Andreas Fackler a47123c4dd Improve Hash impl for Ciphertext. 
This formulation makes it harder to forget updating the `Hash`
implementation if the `Ciphertext` type changes.
 2018-06-20 22:09:43 +02:00
Andreas Fackler 1f27fa6891 Implement Hash for "public" cryptographic types. 
This adds a `Hash` implementation for public keys, commitments,
ciphertexts and signatures — types that might make sense to be included
in special transactions. The `DynamicHoneyBadger` implementation will
require some of them.
