* Upstream GBP, divisor, circuit abstraction, and EC gadgets from FCMP++
* Initial eVRF implementation
Not quite done yet. It needs to communicate the resulting points and proofs to
extract them from the Pedersen Commitments in order to return those, and then
be tested.
* Add the openings of the PCs to the eVRF as necessary
* Add implementation of secq256k1
* Make DKG Encryption a bit more flexible
No longer requires the use of an EncryptionKeyMessage, and allows pre-defined
keys for encryption.
* Make NUM_BITS an argument for the field macro
* Have the eVRF take a Zeroizing private key
* Initial eVRF-based DKG
* Add embedwards25519 curve
* Inline the eVRF into the DKG library
Due to how we're handling share encryption, we'd either need two circuits or to
dedicate this circuit to the DKG. The latter makes sense at this time.
* Add documentation to the eVRF-based DKG
* Add paragraph claiming robustness
* Update to the new eVRF proof
* Finish routing the eVRF functionality
Still needs errors and serialization, along with a few other TODOs.
* Add initial eVRF DKG test
* Improve eVRF DKG
Updates how we calculcate verification shares, improves performance when
extracting multiple sets of keys, and adds more to the test for it.
* Start using a proper error for the eVRF DKG
* Resolve various TODOs
Supports recovering multiple key shares from the eVRF DKG.
Inlines two loops to save 2**16 iterations.
Adds support for creating a constant time representation of scalars < NUM_BITS.
* Ban zero ECDH keys, document non-zero requirements
* Implement eVRF traits, all the way up to the DKG, for secp256k1/ed25519
* Add Ristretto eVRF trait impls
* Support participating multiple times in the eVRF DKG
* Only participate once per key, not once per key share
* Rewrite processor key-gen around the eVRF DKG
Still a WIP.
* Finish routing the new key gen in the processor
Doesn't touch the tests, coordinator, nor Substrate yet.
`cargo +nightly fmt && cargo +nightly-2024-07-01 clippy --all-features -p serai-processor`
does pass.
* Deduplicate and better document in processor key_gen
* Update serai-processor tests to the new key gen
* Correct amount of yx coefficients, get processor key gen test to pass
* Add embedded elliptic curve keys to Substrate
* Update processor key gen tests to the eVRF DKG
* Have set_keys take signature_participants, not removed_participants
Now no one is removed from the DKG. Only `t` people publish the key however.
Uses a BitVec for an efficient encoding of the participants.
* Update the coordinator binary for the new DKG
This does not yet update any tests.
* Add sensible Debug to key_gen::[Processor, Coordinator]Message
* Have the DKG explicitly declare how to interpolate its shares
Removes the hack for MuSig where we multiply keys by the inverse of their
lagrange interpolation factor.
* Replace Interpolation::None with Interpolation::Constant
Allows the MuSig DKG to keep the secret share as the original private key,
enabling deriving FROST nonces consistently regardless of the MuSig context.
* Get coordinator tests to pass
* Update spec to the new DKG
* Get clippy to pass across the repo
* cargo machete
* Add an extra sleep to ensure expected ordering of `Participation`s
* Update orchestration
* Remove bad panic in coordinator
It expected ConfirmationShare to be n-of-n, not t-of-n.
* Improve documentation on functions
* Update TX size limit
We now no longer have to support the ridiculous case of having 49 DKG
participations within a 101-of-150 DKG. It does remain quite high due to
needing to _sign_ so many times. It'd may be optimal for parties with multiple
key shares to independently send their preprocesses/shares (despite the
overhead that'll cause with signatures and the transaction structure).
* Correct error in the Processor spec document
* Update a few comments in the validator-sets pallet
* Send/Recv Participation one at a time
Sending all, then attempting to receive all in an expected order, wasn't working
even with notable delays between sending messages. This points to the mempool
not working as expected...
* Correct ThresholdKeys serialization in modular-frost test
* Updating existing TX size limit test for the new DKG parameters
* Increase time allowed for the DKG on the GH CI
* Correct construction of signature_participants in serai-client tests
Fault identified by akil.
* Further contextualize DkgConfirmer by ValidatorSet
Caught by a safety check we wouldn't reuse preprocesses across messages. That
raises the question of we were prior reusing preprocesses (reusing keys)?
Except that'd have caused a variety of signing failures (suggesting we had some
staggered timing avoiding it in practice but yes, this was possible in theory).
* Add necessary calls to set_embedded_elliptic_curve_key in coordinator set rotation tests
* Correct shimmed setting of a secq256k1 key
* cargo fmt
* Don't use `[0; 32]` for the embedded keys in the coordinator rotation test
The key_gen function expects the random values already decided.
* Big-endian secq256k1 scalars
Also restores the prior, safer, Encryption::register function.
* Rename the coins folder to networks
Ethereum isn't a coin. It's a network.
Resolves#357.
* More renames of coins -> networks in orchestration
* Correct paths in tests/
* cargo fmt
* Remove unsafe creation of dalek_ff_group::EdwardsPoint in BP+
* Rename Bulletproofs to Bulletproof, since they are a single Bulletproof
Also bifurcates prove with prove_plus, and adds a few documentation items.
* Make CLSAG signing private
Also adds a bit more documentation and does a bit more tidying.
* Remove the distribution cache
It's a notable bandwidth/performance improvement, yet it's not ready. We need a
dedicated Distribution struct which is managed by the wallet and passed in.
While we can do that now, it's not currently worth the effort.
* Tidy Borromean/MLSAG a tad
* Remove experimental feature from monero-serai
* Move amount_decryption into EncryptedAmount::decrypt
* Various RingCT doc comments
* Begin crate smashing
* Further documentation, start shoring up API boundaries of existing crates
* Document and clean clsag
* Add a dedicated send/recv CLSAG mask struct
Abstracts the types used internally.
Also moves the tests from monero-serai to monero-clsag.
* Smash out monero-bulletproofs
Removes usage of dalek-ff-group/multiexp for curve25519-dalek.
Makes compiling in the generators an optional feature.
Adds a structured batch verifier which should be notably more performant.
Documentation and clean up still necessary.
* Correct no-std builds for monero-clsag and monero-bulletproofs
* Tidy and document monero-bulletproofs
I still don't like the impl of the original Bulletproofs...
* Error if missing documentation
* Smash out MLSAG
* Smash out Borromean
* Tidy up monero-serai as a meta crate
* Smash out RPC, wallet
* Document the RPC
* Improve docs a bit
* Move Protocol to monero-wallet
* Incomplete work on using Option to remove panic cases
* Finish documenting monero-serai
* Remove TODO on reading pseudo_outs for AggregateMlsagBorromean
* Only read transactions with one Input::Gen or all Input::ToKey
Also adds a helper to fetch a transaction's prefix.
* Smash out polyseed
* Smash out seed
* Get the repo to compile again
* Smash out Monero addresses
* Document cargo features
Credit to @hinto-janai for adding such sections to their work on documenting
monero-serai in #568.
* Fix deserializing v2 miner transactions
* Rewrite monero-wallet's send code
I have yet to redo the multisig code and the builder. This should be much
cleaner, albeit slower due to redoing work.
This compiles with clippy --all-features. I have to finish the multisig/builder
for --all-targets to work (and start updating the rest of Serai).
* Add SignableTransaction Read/Write
* Restore Monero multisig TX code
* Correct invalid RPC type def in monero-rpc
* Update monero-wallet tests to compile
Some are _consistently_ failing due to the inputs we attempt to spend being too
young. I'm unsure what's up with that. Most seem to pass _consistently_,
implying it's not a random issue yet some configuration/env aspect.
* Clean and document monero-address
* Sync rest of repo with monero-serai changes
* Represent height/block number as a u32
* Diversify ViewPair/Scanner into ViewPair/GuaranteedViewPair and Scanner/GuaranteedScanner
Also cleans the Scanner impl.
* Remove non-small-order view key bound
Guaranteed addresses are in fact guaranteed even with this due to prefixing key
images causing zeroing the ECDH to not zero the shared key.
* Finish documenting monero-serai
* Correct imports for no-std
* Remove possible panic in monero-serai on systems < 32 bits
This was done by requiring the system's usize can represent a certain number.
* Restore the reserialize chain binary
* fmt, machete, GH CI
* Correct misc TODOs in monero-serai
* Have Monero test runner evaluate an Eventuality for all signed TXs
* Fix a pair of bugs in the decoy tests
Unfortunately, this test is still failing.
* Fix remaining bugs in monero-wallet tests
* Reject torsioned spend keys to ensure we can spend the outputs we scan
* Tidy inlined epee code in the RPC
* Correct the accidental swap of stagenet/testnet address bytes
* Remove unused dep from processor
* Handle Monero fee logic properly in the processor
* Document v2 TX/RCT output relation assumed when scanning
* Adjust how we mine the initial blocks due to some CI test failures
* Fix weight estimation for RctType::ClsagBulletproof TXs
* Again increase the amount of blocks we mine prior to running tests
* Correct the if check about when to mine blocks on start
Finally fixes the lack of decoy candidates failures in CI.
* Run Monero on Debian, even for internal testnets
Change made due to a segfault incurred when locally testing.
https://github.com/monero-project/monero/issues/9141 for the upstream.
* Don't attempt running tests on the verify-chain binary
Adds a minimum XMR fee to the processor and runs fmt.
* Increase minimum Monero fee in processor
I'm truly unsure why this is required right now.
* Distinguish fee from necessary_fee in monero-wallet
If there's no change, the fee is difference of the inputs to the outputs. The
prior code wouldn't check that amount is greater than or equal to the necessary
fee, and returning the would-be change amount as the fee isn't necessarily
helpful.
Now the fee is validated in such cases and the necessary fee is returned,
enabling operating off of that.
* Restore minimum Monero fee from develop
* Route validators for any active set through sc-authority-discovery
Additionally adds an RPC route to retrieve their P2P addresses.
* Have the coordinator get peers from substrate
* Have the RPC return one address, not up to 3
Prevents the coordinator from believing it has 3 peers when it has one.
* Add missing feature to serai-client
* Correct network argument in serai-client for p2p_validators call
* Add a test in serai-client to check DHT population with a much quicker failure than the coordinator tests
* Update to latest Substrate
Removes distinguishing BABE/AuthorityDiscovery keys which causes
sc_authority_discovery to populate as desired.
* Update to a properly tagged substrate commit
* Add all dialed to peers to GossipSub
* cargo fmt
* Reduce common code in serai-coordinator-tests with amore involved new_test
* Use a recursive async function to spawn `n` DockerTests with the necessary networking configuration
* Merge UNIQUE_ID and ONE_AT_A_TIME
* Tidy up the new recursive code in tests/coordinator
* Use a Mutex in CONTEXT to let it be set multiple times
* Make complimentary edits to full-stack tests
* Augment coordinator P2p connection logs
* Drop lock acquisitions before recursing
* Better scope lock acquisitions in full-stack, preventing a deadlock
* Ensure OUTER_OPS is reset across the test boundary
* Add cargo deny allowance for dockertest fork
* Move logic for evaluating if a cosign should occur to its own file
Cleans it up and makes it more robust.
* Have expected_next_batch return an error instead of retrying
While convenient to offer an error-free implementation, it potentially caused
very long lived lock acquisitions in handle_processor_message.
* Unify and clean DkgConfirmer and DkgRemoval
Does so via adding a new file for the common code, SigningProtocol.
Modifies from_cache to return the preprocess with the machine, as there's no
reason not to. Also removes an unused Result around the type.
Clarifies the security around deterministic nonces, removing them for
saved-to-disk cached preprocesses. The cached preprocesses are encrypted as the
DB is not a proper secret store.
Moves arguments always present in the protocol from function arguments into the
struct itself.
Removes the horribly ugly code in DkgRemoval, fixing multiple issues present
with it which would cause it to fail on use.
* Set SeraiBlockNumber in cosign.rs as it's used by the cosigning protocol
* Remove unnecessary Clone from lambdas in coordinator
* Remove the EventDb from Tributary scanner
We used per-Transaction DB TXNs so on error, we don't have to rescan the entire
block yet only the rest of it. We prevented scanning multiple transactions by
tracking which we already had.
This is over-engineered and not worth it.
* Implement borsh for HasEvents, removing the manual encoding
* Merge DkgConfirmer and DkgRemoval into signing_protocol.rs
Fixes a bug in DkgConfirmer which would cause it to improperly handle indexes
if any validator had multiple key shares.
* Strictly type DataSpecification's Label
* Correct threshold_i_map_to_keys_and_musig_i_map
It didn't include the participant's own index and accordingly was offset.
* Create TributaryBlockHandler
This struct contains all variables prior passed to handle_block and stops them
from being passed around again and again.
This also ensures fatal_slash is only called while handling a block, as needed
as it expects to operate under perfect consensus.
* Inline accumulate, store confirmation nonces with shares
Inlining accumulate makes sense due to the amount of data accumulate needed to
be passed.
Storing confirmation nonces with shares ensures that both are available or
neither. Prior, one could be yet the other may not have been (requiring an
assert in runtime to ensure we didn't bungle it somehow).
* Create helper functions for handling DkgRemoval/SubstrateSign/Sign Tributary TXs
* Move Label into SignData
All of our transactions which use SignData end up with the same common usage
pattern for Label, justifying this.
Removes 3 transactions, explicitly de-duplicating their handlers.
* Remove CurrentlyCompletingKeyPair for the non-contextual DkgKeyPair
* Remove the manual read/write for TributarySpec for borsh
This struct doesn't have any optimizations booned by the manual impl. Using
borsh reduces our scope.
* Use temporary variables to further minimize LoC in tributary handler
* Remove usage of tuples for non-trivial Tributary transactions
* Remove serde from dkg
serde could be used to deserialize intenrally inconsistent objects which could
lead to panics or faults.
The BorshDeserialize derives have been replaced with a manual implementation
which won't produce inconsistent objects.
* Abstract Future generics using new trait definitions in coordinator
* Move published_signed_transaction to tributary/mod.rs to reduce the size of main.rs
* Split coordinator/src/tributary/mod.rs into spec.rs and transaction.rs
Event retrieval was prior:
- Retrieve all events in the block, which may be hundreds of KB
- Filter to just a few
Since it's frequent to want multiple sets of events, each filtered in their own
way, this caused the retrieval to happen multiple times. Now, it only will
happen once.
Also has the scoped clients take a reference, not an owned TemporalSerai.
Uses a full-fledged serai-abi to do so.
Removes use of UncheckedExtrinsic as a pointlessly (for us) length-prefixed
block with a more complicated signing algorithm than advantageous.
In the future, we should considering consolidating the various primitives
crates. I'm not convinced we benefit from one primitives crate per pallet.
* Remove subxt
Removes ~20 crates from our Cargo.lock.
Removes downloading the metadata and enables removing the getMetadata RPC route
(relevant to #379).
Moves forward #337.
Done now due to distinctions in the subxt 0.32 API surface which make it
justifiable to not update.
* fmt, update due to deny triggering on a yanked crate
* Correct the handling of substrate_block_notifier now that it's ephemeral, not long-lived
* Correct URL in tests/coordinator from ws to http
processor isn't intended to be used as a library, yet serai-processor-tests
does pull it in as a lib. This caused serai-processor-tests to need to compile
rocksdb, which added multiple minutes to the compilation time.
* Updates to modern dockertest
* More updates to latest dockertest
* Update Cargo.lock to dockertest with handle restored
* clippy coordinator tests
* clippy full-stack tests
* Remove kayabaNerve branch for official repo's latest commit hash
* Update serai-client, remove reliance on the existence of a handle fn
* Don't use the hex encoding of unique_id in dockertests
Gets our hostnames just below 64 bytes, resolving test failures on at least
Debian-based systems.
* Use Network::Isolated for all dockertest instances
* Correct error from prior commit's edits
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.
The Processor's coins folder referred to the networks it could process, as did
its Coin trait. This, and other similar cases throughout the codebase, have now
been corrected.
Also corrects dated documentation for a key pair is confirmed under the
validator-sets pallet.
Writes a custom unsigned extrinic creator due to subxt having an internal error
with the scale metadata. While the code in our scope increased, it's much more
ergonomic to our usage. We may end up rewriting most of subxt, eventually.
