* Add v1 ring sig verifying
* allow calculating signature hash for v1 txs
* add unreduced scalar type with recovery
I have added this type for borromen sigs, the ee field can be a normal
scalar as in the verify function the ee
field is checked against a reduced scalar mean for it to verify as
correct ee must be reduced
* change block major/ minor versions to u8
this matches Monero
I have also changed a couple varint functions to accept the `VarInt`
trait
* expose `serialize_hashable` on `Block`
* add back MLSAG verifying functions
I still need to revert the commit removing support for >1 input MLSAG FULL
This adds a new rct type to separate Full and simple rct
* add back support for multiple inputs for RCT FULL
* comment `non_adjacent_form` function
also added `#[allow(clippy::needless_range_loop)]` around a loop as without a re-write satisfying clippy without it will make the function worse.
* Improve Mlsag verifying API
* fix rebase errors
* revert the changes on `reserialize_chain`
plus other misc changes
* fix no-std
* Reduce the amount of rpc calls needed for `get_block_by_number`.
This function was causing me problems, every now and then a node would return a block with a different number than requested.
* change `serialize_hashable` to give the POW hashing blob.
Monero calculates the POW hash and the block hash using *slightly* different blobs :/
* make ring_signatures public and add length check when verifying.
* Misc improvements and bug fixes

* Have processor report errors during the DKG to the coordinator
* Add RemoveParticipant, InvalidDkgShare to coordinator
* Route DKG blame around coordinator
* Allow public construction of AdditionalBlameMachine
Necessary for upcoming work on handling DKG blame in the processor and
coordinator.
Additionally fixes a publicly reachable panic when commitments parsed with one
ThresholdParams are used in a machine using another set of ThresholdParams.
Renames InvalidProofOfKnowledge to InvalidCommitments.
* Remove unused error from dleq
* Implement support for VerifyBlame in the processor
* Have coordinator send the processor share message relevant to Blame
* Remove desync between processors reporting InvalidShare and ones reporting GeneratedKeyPair
* Route blame on sign between processor and coordinator
Doesn't yet act on it in coordinator.
* Move txn usage as needed for stable Rust to build
* Correct InvalidDkgShare serialization
If a user transferred in without an InInstruction, and the amount exactly
matched a forwarded output, the user's output would fulfill the
forwarding. Then the forwarded output would come along, have no InInstruction,
and be refunded (to the prior multisig) when the user should've been refunded.
Adding this new address type resolves such concerns.
The higher-level scanner code in multisigs/mod.rs now creates a series of plans
with limited context. These include forwarding and refunding plans, moving all
handling of forwarding flags on the scanner's clock and therefore safe.
Also simplifies the refunding a decent bit.
This code is still largely designed around the idea a payment for a network is
fungible with any other, which isn't true. This starts moving past that.
Asserts are added to ensure the integrity of coin to the scheduler (which is
now per key per coin, not per key alone) and in Bitcoin/Monero prepare_send.
ethers-solc was used for a type (now manually specified) and to call out to
solc. Since Foundry was already a documented dependency, a call to it now
handles building.
Removing this single crate removes a total of 17 crates from our dependency
tree. While these may still be around due to Foundry, they at least may not
be.
Further work to remove the requirement on Foundry for solc alone would be
appreciated.
Not currently used, notably increases our dependency tree.
I wouldn't remove it if we planned to use it. From my understanding, all
benchmarking will be per pallet, voiding our need to have this for the node.
I don't like blindly retrying in the Monero library. The amount of errors,
which weren't present with reqwest (well, the error rate was the same, yet due
to a distinct bug this code fixed), demand we do *something* though.
The trace log shows hyper is erroring with 0 bytes of the response read. My
guess is it's somehow a closed connection? A connection pool would detect this
and have created a new connection (as this does, except once finding out
there's an issue).
While we should be able to detect this with `ready()`, we do call ready and it
claims no error. We also can successfully write which makes this... a mess.
Hopefully, it either actually works as intended, yet it at least requires two
consecutive errors which should be much less frequent.
The prior system spawned a new connection per request to enable parallelism,
yet kept hitting hyper::IncompleteMessages I couldn't track down. This
attempts to resolve those by a long-lived socket.
Halves the amount of requests per-authenticated RPC call, and accordingly is
likely still better overall.
I don't believe this is resolved yet but this is still worth pushing.
reqwest was replaced with hyper and hyper-rustls within monero-serai due to
reqwest *solely* offering a connection pool API. In the process, it was
demonstrated how quickly we can achieve equivalent functionality to reqwest for
our use cases with a fraction of the code.
This adds our own reqwest alternative to the tree, applying it to both
bitcoin-serai and message-queue. By doing so, bitcoin-serai decreases its tree
by 21 packages and the processor by 18. Cargo.lock decreases by 8 dependencies,
solely adding simple-request. Notably removed is openssl-sys and openssl.
One noted decrease functionality is the requirement on the system having
installed CA certificates. While we could fallback to the rustls certificates
if the system doesn't have any, that's blocked by
https://github.com/rustls/hyper-rustls/pulls/228.
Removes bitcoin-serai's usage of sha2 for bitcoin-hashes. While sha2 is still
in play due to modular-frost (more specifically, due to ciphersuite), this
offers a bit more performance (assuming equivalency between sha2 and
bitcoin-hashes' impl) due to removing a static for a const.
Makes secp256k1 a dev dependency for bitcoin-serai. While secp256k1 is still
pulled in via bitcoin, it's hopefully slightly better to compile now and makes
usage of secp256k1 an implementation detail of bitcoin (letting it change it
freely).
Also offers slightly more efficient signing as we don't decode to a signature
just to re-encode for the transaction.
Removes a 20s sleep for a check every second, up to 20 times, for reduced test
times in the processor.

It *looks like* hyper will drop the connection once its request sender is
dropped, regardless of if the last request hasn't had its response completed.
This attempts to resolve some spurious connection errors.
* 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
