Merge pull request #163 from poanetwork/afck-queue-fields 
Remove queue fields from Agreement, CommonCoin, Broadcast and CommonSubset.
 2018-07-26 08:43:07 +02:00
Andreas Fackler 30c5805446 Remove output and message queue from CommonCoin. 2018-07-24 11:57:50 +02:00
Andreas Fackler 984bb49fdc Accept more types in threshold crypto API. 
This removes some unnecessary allocation and conversion by accepting
more primitive types and references as the index in threshold decryption
and signing, and as the argument to a polynomial.

Merge branch 'master' into vk-api-refactor66 2018-07-13 13:53:21 +01:00
Marc Brinkmann 5336fbe707 Added `RandomAdversary` and the necessary auxiliary functions. 
Random adversaries are created for `broadcast` and `honey_badger`.  Random value generation was added for all type-dependencies of these algorithms, causing the `Rand` trait to be implement for a large portion of the codebase.

Additionally, `MessageWithSender` turned into an actual struct, making it much easier to handle. Tuple-like construction is still available through `MessageWithSender::new()`.

Vladimir Komendantskiy 7fb1017bb1 changed Step::output to Vec but that didn't fix the dynamic HB test 2018-07-12 21:23:52 +01:00
Vladimir Komendantskiy 1254d40147 fixed a starvation issue in Agreement when num_faulty=0 2018-07-12 15:12:06 +01:00
Vladimir Komendantskiy 0ba06fdb76 added step output in DistAlgorithm 2018-07-12 14:54:05 +01:00
c0gent f0ed2e6e12 Make `*HoneyBadger` types thread safe. 
Replaces `Rc` with `Arc`. This allows usage from different threads
which will be necessary for use with Parity.

Peter van Nostrand 6783ece9b0 Added faulty node logging to algorithms. 2018-07-09 13:45:11 -04:00
Andreas Fackler c42f606644 Fix module docs. (Review comments.) 2018-07-05 17:51:55 +02:00
Andreas Fackler f05e087492 Improve mod docs (review comments). 2018-07-05 11:45:30 +02:00
Andreas Fackler 2a30860bb0 Add agreement module-level docs. 2018-07-05 11:45:30 +02:00
Andreas Fackler daab0eb564 Add coin docs, change parity computation. 
This makes the signature parity computation take into account all bits,
not just the last one of each byte.

Andreas Fackler bbc27e8a66 Update terminology: "observers" and "validators" 2018-07-02 14:14:19 +02:00
Andreas Fackler 2b4f77f11c Avoid redundant key computations. 2018-06-27 14:47:05 +02:00
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

Andreas Fackler e11f183db2 Remove generic E: Engine from crypto. 2018-06-22 10:08:23 +02:00
Andreas Fackler 83f8d61402 Support serde by default. 
This removes the `serialization-serde` feature, since serde is already
used internally and therefore a dependency anyway.
 2018-06-20 10:21:52 +02:00
Andreas Fackler 66f396e01c Remove more NodeUid trait bounds. 
Use a `BTreeMap` instead of `HashMap` in `NetworkInfo`. The number of
nodes can't grow very large anyway.
 2018-06-18 16:37:07 +02:00
Andreas Fackler 3f707a8e12 Return proposer info from HoneyBadger. 
Also, consistently name generic arguments, and remove some unused trait
bounds.
