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.
The reproducible runtime test failed due to running out of space. If we have
multiple tests failing due to out of space, and all of our tests have these
unused, it makes sense just to always so uninstall.
Also extends the time limit of reproducible-runtime, as 2h has been hit a few
times before.
They assumed processor 0 had keys `i = 1`. Under the new validator-set code,
the first key is the one with the highest amount, In case of tie, the key (or
as of the last commit, a Blake hash) decides order.
This commit kludges in a mapping from processor index to assigned key index, no
longer assuming its value.
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.

Renames Update to SignedBatch.
Checks Batch equality via a hash of the InInstructions. That prevents needing
to keep the Batch in node state or TX introspect.
key used to be empty. As part of implementing support for multisig rotation
into the coordinator, it was easiest to set the key to the substrate key. While
the coordinator and full stack tests were updated, the processor tests weren't.
This does that.
Prior, we only supported a single Tributary per network, and spawned a task to
handled Processor messages per Tributary. Now, we handle Processor messages per
network, yet we still only supported a single Tributary in that handling
function.
Now, when we handle a message, we load the Tributary which is relevant. Once we
know it, we ensure we have it (preventing race conditions), and then proceed.
We do need work to check if we should have a Tributary, or if we're not
participating. We also need to check if a Tributary has been retired, meaning
we shouldn't handle any transactions related to them, and to clean up retired
Tributaries.
