      client/beefy: persist voter state (#12712) · 3e7a2778
      Adrian Catangiu authored 
      

* client/beefy: prepare worker for persisting state

* client/beefy: persist voter state

* client/beefy: initialize persistent state

* client/beefy: try to vote from the very beginning

Now that voter is initialized from persistent state, it makes
sense that it can attempt voting right away. This also helps
the genesis case when we consider block `One` as mandatory.

* client/beefy: add tests for voter state db
* client/beefy: persist voter state as soon as initialized
* client/beefy: make sure min-block-delta is at least 1
* client/beefy: persist state after voting

Persist state after handling self vote to avoid double voting in case
of voter restarts.

* client/beefy: persist state after handling mandatory block vote

For mandatory blocks we want to make sure we're not losing votes
in case of crashes or restarts, since voter will not make further
progress without finalizing them.

* frame/beefy: use GENESIS_AUTHORITY_SET_ID on pallet genesis

* client/beefy: initialize voter at either genesis or last finalized
To guarantee unbroken chain of mandatory blocks justifications, voter
will always resume from either last BEEFY-justified block or
`pallet-beefy` genesis, whichever is more recent.

Initialization walks back the chain from latest GRANDPA finalized
block looking for one of the above. Along the way, it also records
and enqueues for processing any BEEFY mandatory blocks that have
been already GRANDPA finalized but not BEEFY finalized.

* client/beefy: decouple voter init from aux db state load
* client/beefy: fix voter init tests
* remove debug prints
* gadget future must be type ()
* fix init from last justification

      Lean BEEFY to Full BEEFY - don't skip (older) mandatory blocks and import justifications (#11821) · 1c6867c6
      Adrian Catangiu authored 
      

* client/beefy: don't accept vote for older rounds

* client/beefy: clean up and reorg the worker struct

* client/beefy: first step towards Full BEEFY

The first step from Lean->Full BEEFY is to have the worker
enforce uninterrupted line of BEEFY finalized mandatory blocks.

There is one mandatory block per session (the first block in the
session). As such, votes processing and votes generation now
enforces that all mandatory blocks are finalized in strict
monotonically increasing sequence and no block 'N' will be worked
on if there is any GRANDPA finalized but BEEFY non-final mandatory
block 'M', where 'M < N'.

Implementation details:

- Introduced 'VoterOracle' to separate the voting decisions logic,
  and track new/pending sessions.

- New sessions get queued up with the worker operating either:
  1. up-to-date - all mandatory blocks leading up to current GRANDPA
     finalized: queue has ONE element, the 'current session' where
     `mandatory_done == true`,
  2. lagging behind GRANDPA: queue has [1, N] elements, where all
     `mandatory_done == false`.
     In this state, everytime a session gets its mandatory block
     BEEFY finalized, the session is popped off the queue,
     eventually getting to operating mode `1. up-to-date`.

- Votes get triaged and those that fall withing the `VoterOracle`
  allowed window get processed, the others get dropped if stale,
  or buffered for later processing (when they reach the window).

- Worker general code was also updated to fall in one of two roles:
  1. react to external events and change internal 'state',
  2. generate events/votes based on internal 'state'.

      pallet-beefy-mmr: add API for BEEFY Authority Sets (#11406) · 3018051c
      Adrian Catangiu authored 
      

* pallet-beefy: add Config::OnNewValidatorSet type

Add a hook to pallet-beefy for doing specific work when
BEEFY validator set changes.

For example, this can be used by pallet-beefy-mmr to cache
a lightweight MMR root over validators and make it available
to light clients.

* pallet-beefy-mmr: implement OnNewValidatorSet

Implement pallet-beefy::OnNewValidatorSet to be notified of BEEFY
validator set changes. Use the notifications to compute and cache
a light weight 'BEEFY authority set' which is an MMR root over
BEEFY validator set plus some extra info.

Previously, pallet-beefy-mmr was interogating pallet-beefy about
validator set id on every block to find out when it needs to recompute
the authority set.
By using the event-driven approach in this commit, we also save one
extra state interogation per block.

* pallet-beefy-mmr: add new authority_set() API

Expose current and next BEEFY authority sets through runtime API.
These can be directly used by light clients to avoid having them
compute them themselves based on BEEFY validator sets.

      Implement Lean BEEFY (#10882) · 498e8c18
      Adrian Catangiu authored 
      

Simplified BEEFY worker logic based on the invariant that GRANDPA
will always finalize 1st block of each new session, meaning BEEFY
worker is guaranteed to receive finality notification for the
BEEFY mandatory blocks.

Under these conditions the current design is as follows:
- session changes are detected based on BEEFY Digest present in
  BEEFY mandatory blocks,
- on each new session new `Rounds` of voting is created, with old
  rounds being dropped (for gossip rounds, last 3 are still alive
  so votes are still being gossiped),
- after processing finality for a block, the worker votes if
  a new voting target has become available as a result of said
  block finality processing,
- incoming votes as well as self-created votes are processed
  and signed commitments are created for completed BEEFY voting
  rounds,
- the worker votes if a new voting target becomes available
  once a round successfully completes.

On worker startup, the current validator set is retrieved from
the BEEFY pallet. If it is the genesis validator set, worker
starts voting right away considering Block #1 as session start.

Otherwise (not genesis), the worker will vote starting with
mandatory block of the next session.

Later on when we add the BEEFY initial-sync (catch-up) logic,
the worker will sync all past mandatory blocks Signed Commitments
and will be able to start voting right away.

BEEFY mandatory block is the block with header containing the BEEFY
`AuthoritiesChange` Digest, this block is guaranteed to be finalized
by GRANDPA.

This session-boundary block is signed by the ending-session's
validator set. Next blocks will be signed by the new session's
validator set. This behavior is consistent with what GRANDPA does
as well.

Also drop the limit N on active gossip rounds. In an adversarial
network, a bad actor could create and gossip N invalid votes with
round numbers larger than the current correct round number. This
would lead to votes for correct rounds to no longer be gossiped.

Add unit-tests for all components, including full voter consensus
tests.

      * Introduce `SecretUri`

* `inspect-key`: Adds support for `expect-public`

`expect-public` can be used to check that a given secret uri corresponds to the given public key.
This is mainly useful when the secret uri is protected by a password and a new derived account
should be generated. With `--expect-public` the user can pass the public key/account-id of the
"base" secret uri aka the one without any derivation to ensure the correct password was inserted.
