* Label the version as an alpha
* Add versions to Cargo.tomls
* Update to Zeroize 1.5
* Drop patch versions from monero-serai Cargo.toml
* Add a repository field
* Move generators to OUT_DIR
IIRC, I didn't do this originally as it constantly re-generated them.
Unfortunately, since cargo is complaining about .generators, we have to.
* Remove Timelock::fee_weight
Transaction::fee_weight's has a comment, "Assumes Timelock::None since
this library won't let you create a TX with a timelock". Accordingly,
this is dead code.
Despite being slower and only used for blinding values, its still
extremely performant. 20 is far more standard and will avoid an eye
raise from reviewers.
There is a slight note we only implement u64 varint's, while Monero does
it for arbitrary uints, yet that's not relevant at this time. It is
documented in #25.
Creates a new monero-generators crate so the monero crate can run the
code in question at build time.
Saves several seconds from running the tests.
Closes https://github.com/serai-dex/serai/issues/101.
* Apply Zeroize to nonces used in Bulletproofs
Also makes bit decomposition constant time for a given amount of
outputs.
* Fix nonce reuse for single-signer CLSAG
* Attach Zeroize to most structures in Monero, and ZOnDrop to anything with private data
* Zeroize private keys and nonces
* Merge prepare_outputs and prepare_transactions
* Ensure CLSAG is constant time
* Pass by borrow where needed, bug fixes
The past few commitments have been one in-progress chunk which I've
broken up as best read.
* Add Zeroize to FROST structs
Still needs to zeroize internally, yet next step. Not quite as
aggressive as Monero, partially due to the limitations of HashMaps,
partially due to less concern about metadata, yet does still delete a
few smaller items of metadata (group key, context string...).
* Remove Zeroize from most Monero multisig structs
These structs largely didn't have private data, just fields with private
data, yet those fields implemented ZeroizeOnDrop making them already
covered. While there is still traces of the transaction left in RAM,
fully purging that was never the intent.
* Use Zeroize within dleq
bitvec doesn't offer Zeroize, so a manual zeroing has been implemented.
* Use Zeroize for random_nonce
It isn't perfect, due to the inability to zeroize the digest, and due to
kp256 requiring a few transformations. It does the best it can though.
Does move the per-curve random_nonce to a provided one, which is allowed
as of https://github.com/cfrg/draft-irtf-cfrg-frost/pull/231.
* Use Zeroize on FROST keygen/signing
* Zeroize constant time multiexp.
* Correct when FROST keygen zeroizes
* Move the FROST keys Arc into FrostKeys
Reduces amount of instances in memory.
* Manually implement Debug for FrostCore to not leak the secret share
* Misc bug fixes
* clippy + multiexp test bug fixes
* Correct FROST key gen share summation
It leaked our own share for ourself.
* Fix cross-group DLEq tests
Considering they take 7 seconds to generate, thanks to #68, the ability
to generate them at the start instead of on first BP is greatly
appreciated.
Also performs minor cleanups regarding BPs.
* Use a struct in an enum for Bulletproofs
* verification bp working for just one proof
* add some more assert tests
* Clean BP verification
* Implement batch verification
* Add a debug assertion w_cache isn't 0
It's initially set to 0 and if not updated, this would be broken.
* Correct Monero workflow yaml
* Again try to corrent Monero workflow yaml
* Again
* Finally
* Re-apply weights as required by Bulletproofs
Removing these was insecure and my fault.

* Consolidate GitHub CI actions, split out Monero
build now includes the specified Rust toolchain/components.
Added a test dependencies action which grabs Foundry and Monero.
Split the Monero v14 job into a matrixed job in its own workflow flow.
It's now only run when Monero has changes.
* Correct Monero unit/integration tests run timing
Additionally tests a feature-less Monero build.
Also removes a pointless Monero file, which already should have been
removed, causing this workflow to be triggered.
* Correct exclusion and paths
Updates to FROST should re-run the Monero tests to ensure it didn't
introduce API incompatibilities.
* Initial stab at Bulletproofs+
Does move around the existing Bulletproofs code, does still work as
expected.
* Make the Clsag RCTPrunable type work with BP and BP+
* Initial set of BP+ bug fixes
* Further bug fixes
* Remove RING_LEN as a constant
* Monero v16 TX support
Doesn't implement view tags, nor going back to v14, nor the updated BP
clawback logic.
* Support v14 and v16 at the same time
Introduces missing CLSAG checks. The only difference now should be the
additional rejection of torsioned points, which is relevant to
https://github.com/serai-dex/serai/issues/25. Considering this is only
currently used for FROST verification, this should be fine.
Closes https://github.com/serai-dex/serai/issues/19 by making it
irrelevant.
Increases priority of https://github.com/serai-dex/serai/issues/68, as
now it's used for the BP generators which are done at first-proof.
Also merges BP's stricter hash_to_point with the library's, since CLSAG
has the same bound.
* Initial attempt at Bulletproofs
I don't know why this doesn't work. The generators and hash_cache lines
up without issue. AFAICT, the inner product proof is valid as well, as
are all included formulas.
* Add yinvpow asserts
* Clean code
* Correct bad imports
* Fix the definition of TWO_N
Bulletproofs work now :D
* Tidy up a bit
* fmt + clippy
* Compile a variety of XMR dependencies with optimizations, even under dev
The Rust bulletproof implementation is 8% slower than C right now, under
release. This is acceptable, even if suboptimal. Under debug, they take
a quarter of a second to two seconds though, depending on the amount of
outputs, which justifies this move.
* Remove unnecessary deref in BPs
* Remove the Monero CMake and make
* Download the Monero daemon instead of building it
* Cache the Monero daemon
Prevents hammering the Monero servers, should reduce CI time.
* Correct YAML
* Add back sodium-dev
* Create an independent job for downloading the Monero daemon
Improves parallelism while decreasing the amount of work re-done if
build fails. Also increases modularity.
* Correct Monero job definition
* Correct skipping the Monero download on cache hit
* begin to setup ci
* attempt to fix build
* fix paths in build script
* fix
* satisfy clippy
* update fmt check to use nightly
* use nightly for build
* fmt
* fix fmt install
* update test script
* try to fix fmt
* merge w develop
* maybe fix build script
* install wasm toolchain
* install solc-select, use stable rust to build
* Correct clippy warnings
Currently intended to be done with:
cargo clippy --features "recommended merlin batch serialize experimental
ed25519 ristretto p256 secp256k1 multisig" -- -A clippy::type_complexity
-A dead_code
* Remove try-runtime
I tried to get this to work for an hour. I have no idea why it doesn't,
yet it doesn't.
* Rewrite workflow
Splits tasks into a more modular structure. Also uses
actions-rs/toolchain.
* Add a cache
* Immediately try building ETH/Monero while this is fixed
Adds solc-select use.
* Revert selective advance building of ETH/XMR
ETH builds now, so it hopefully should work now.
Also moves from on push to on push to develop.
* Install Monero runtime dependencies
Specify missing Rust toolchain setting.
* Correct multi-line commands
* Fix multi-line commands again
Cache Ethereum artifacts.
* Add Foundry
* Move Clippy under build
* Minimal rustup
Adds wasm Clippy. Puts Clippy before build.
* Use nightly clippy
* Remove old clippy call from under build
* Have the Monero build script support ARCH specification
Requirement for CI.
* Add WASM toolchain to tests
* Remove Ethereum cache which did not work as needed
* Remove extraneous quotes which broke builds on Arch

The two-generator limit wasn't required nor beneficial. This does
theoretically optimize FROST, yet not for any current constructions. A
follow up proof which would optimize current constructions has been
noted in #38.
Adds explicit no_std support to the core DLEq proof.
Closes#34.
While Serai only needs the simple DLEq which was already present under
monero, this migrates the implementation of the cross-group DLEq I
maintain into Serai. This was to have full access to the ecosystem of
libraries built under Serai while also ensuring support for it.
The cross_group curve, which is extremely experimental, is feature
flagged off. So is the built in serialization functionality, as this
should be possible to make nostd once const generics are full featured,
yet the implemented serialization adds the additional barrier of
std::io.
Increases usage of standardization while expanding dalek_ff_group.
Closes https://github.com/serai-dex/serai/issues/26 by moving
dfg::EdwardsPoint to only be for the prime subgroup.
Updates how change outputs are handled, with a far more logical
construction offering greater flexibility.
prepare_outputs can not longer error. SignaableTransaction::new will.
Modifies FROST behavior so group_key has the offset applied regardless
of if view was called. The unaltered secret_share and
verification_shares (as they have differing values depending on the
signing set) are no longer publicly accessible.
Doesn't fully utilize ec's hash2curve module as k256 Scalar doesn't have
FromOkm for some reason. The previously present bigint reduction is
preserved.
Updates ff/group to 0.12.
Premised on https://github.com/cfrg/draft-irtf-cfrg-frost/pull/205 being
merged, as while this Ed25519 is vector compliant, it's technically not
spec compliant due to that conflict.
