They were already banned form publishing `Batch`s, yet the ability to set keys
enabled changing how certain functionality in the coordinator operated.
Removing this malleability ensures operation as expected.

* Update the coordinator to give key shares based on weight, not based on existence
Participants are now identified by their starting index. While this compiles,
the following is unimplemented:
1) A conversion for DKG `i` values. It assumes the threshold `i` values used
will be identical for the MuSig signature used to confirm the DKG.
2) Expansion from compressed values to full values before forwarding to the
processor.
* Add a fn to the DkgConfirmer to convert `i` values as needed
Also removes TODOs regarding Serai ensuring validator key uniqueness +
validity. The current infra achieves both.
* Have the Tributary DB track participation by shares, not by count
* Prevent a node from obtaining 34% of the maximum amount of key shares
This is actually mainly intended to set a bound on message sizes in the
coordinator. Message sizes are amplified by the amount of key shares held, so
setting an upper bound on said amount lets it determine constants. While that
upper bound could be 150, that'd be unreasonable and increase the potential for
DoS attacks.
* Correct the mechanism to detect if sufficient accumulation has occured
It used to check if the latest accumulation hit the required threshold. Now,
accumulations may jump past the required threshold. The required mechanism is
to check the threshold wasn't prior met and is now met.
* Finish updating the coordinator to handle a multiple key share per validator environment
* Adjust stategy re: preventing noce reuse in DKG Confirmer
* Add TODOs regarding dropped transactions, add possible TODO fix
* Update tests/coordinator
This doesn't add new multi-key-share tests, it solely updates the existing
single key-share tests to compile and run, with the necessary fixes to the
coordinator.
* Update processor key_gen to handle generating multiple key shares at once
* Update SubstrateSigner
* Update signer, clippy
* Update processor tests
* Update processor docker tests
Resolves#353
Implements code such that:
- 80% of validators (by stake) must be in favor of a signal for the network to
be
- 80% of networks (by stake) must be in favor of a signal for it to be locked
in
- After a signal has been locked in for two weeks, the network halts
The intention is to:
1) Not allow validators to unilaterally declare new consensus rules.
No method of declaring new consensus rules is provided by this pallet. Solely a
way to deprecate the current rules, with a signaled for successor. All nodes
must then individually decide whether or not to download and run a new node
which has new rules, and if so, which rules.
2) Not place blobs on chain.
Even if they'd be reproducible, it's just a lot of data to chuck on the
blockchain.
Adds Event::SetRetired to validator-sets.
Emit TributaryRetired.
Replaces is_active_set, which made multiple network requests, with
is_retired_tributary, a DB read.
Performs most of the removals necessary upon TributaryRetired.
Still needs to clean up the actual Tributary/Tendermint tasks.
pre_dispatch is guaranteed by documentation to be called and persisted.
validate_unsigned is not, though the provided pre_dispatch does by default call
validate_unsigned. By explicitly providing our own pre_dispatch, we accomplish
the bounds we require and expect, only being invalidated on Substrate
redefining their API.
We should still test this, yet since we call retire_session in
validate_unsigned, any test of rotation will test it's being properly called.
Sets a stake requirement of 100k for Serai and Monero, as Serai doesn't have
stake requirements and Monero isn't expected to see as much
volume/institutional support as Bitcoin/Ethereum.
We took with `amount`, not `prior`, allowing multiple presences in
SortedAllocations.
While spam is limited by the amount of nibbles in the amount, the key provides
a much larger space to abuse. Inserting a cryptographic hash prevents its use
for abuse.
* initial staking pallet
* add staking pallet to runtime
* support session rotation for serai
* optimizations & cleaning
* fix deny
* add serai network to initial networks
* a few tweaks & comments
* fix some pr comments
* Rewrite validator-sets with logarithmic algorithms
Uses the fact the underlying DB is sorted to achieve sorting of potential
validators by stake.
Removes release of deallocated stake for now.

Provides a DST, and associated metadata as beneficial.
Also utilizes MuSig's context to session-bind. Since set_keys_messages also
binds to set, this is semi-redundant, yet that's appreciated.
Needed for the in-instructions pallet to verify in-instructions are
appropriately signed and continue developing that.
Fixes a bug in the validator-sets pallet, moves several items from the pallet
to primitives.
Updates to polkadot-v0.9.40, with a variety of dependency updates accordingly.
Substrate thankfully now uses k256 0.13, pathing the way for #256. We couldn't
upgrade to polkadot-v0.9.40 without this due to polkadot-v0.9.40 having
fundamental changes to syncing. While we could've updated tendermint, it's not
worth the continued development effort given its inability to work with
multiple validator sets.
Purges sc-tendermint. Keeps tendermint-machine for #163.
Closes#137, #148, #157, #171. #96 and #99 should be re-scoped/clarified. #134
and #159 also should be clarified. #169 is also no longer a priority since
we're only considering temporal deployments of tendermint. #170 also isn't
since we're looking at effectively sharded validator sets, so there should
be no singular large set needing high performance.
