If instead of intaking calls, we intake code, we can deploy a fresh contract
which makes arbitrary calls *without* attempting to build our abstraction
layer over the concept.
This should have the same gas costs, as we still have one contract deployment.
The new contract only has a constructor, so it should have no actual code and
beat the Sandbox in that regard? We do have to call into ourselves to meter the
gas, yet we already had to call into the deployed Sandbox to achieve that.
Also re-defines the OutInstruction to include tokens, implements
OutInstruction-specified gas amounts, bumps the Solidity version, and other
such misc changes.
Moves the coordinator loop out of serai-bitcoin-processor, completing it.
Fixes a potential race condition in the message-queue regarding multiple
sockets sending messages at once.
I don't love this. I wanted to simply add this function to `processor/key-gen`,
but then anyone who wants a view key needs to pull in Bulletproofs which is a
mess of code. They'd also be subject to an AGPL licensed library.
This is so small it should be a primitive elsewhere, yet there is no primitives
library eligible. Maybe serai-client since that has the code to make
transactions to Serai (and will have this as a dependency)? Except then the
processor has to import serai-client when this rewrite removed it as a
dependency.
The main benefit is whatever scheduler is in use, we now have a single API to
receive TXs to sign (which is of value to the TX signer crate we'll inevitably
build).
Abstract, to be done for the transactions, the batches, the cosigns, the slash
reports, everything. It has a minimal API itself, intending to be as clear as
possible.
* 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.
* move economic security into it's own pallet
* fix deny
* Update Cargo.toml, .github for the new crates
* Remove unused import

* 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
* Clean up Ethereum
* Consistent contract address for deployed contracts
* Flesh out Router a bit
* Add a Deployer for DoS-less deployment
* Implement Router-finding
* Use CREATE2 helper present in ethers
* Move from CREATE2 to CREATE
Bit more streamlined for our use case.
* Document ethereum-serai
* Tidy tests a bit
* Test updateSeraiKey
* Use encodePacked for updateSeraiKey
* Take in the block hash to read state during
* Add a Sandbox contract to the Ethereum integration
* Add retrieval of transfers from Ethereum
* Add inInstruction function to the Router
* Augment our handling of InInstructions events with a check the transfer event also exists
* Have the Deployer error upon failed deployments
* Add --via-ir
* Make get_transaction test-only
We only used it to get transactions to confirm the resolution of Eventualities.
Eventualities need to be modularized. By introducing the dedicated
confirm_completion function, we remove the need for a non-test get_transaction
AND begin this modularization (by no longer explicitly grabbing a transaction
to check with).
* Modularize Eventuality
Almost fully-deprecates the Transaction trait for Completion. Replaces
Transaction ID with Claim.
* Modularize the Scheduler behind a trait
* Add an extremely basic account Scheduler
* Add nonce uses, key rotation to the account scheduler
* Only report the account Scheduler empty after transferring keys
Also ban payments to the branch/change/forward addresses.
* Make fns reliant on state test-only
* Start of an Ethereum integration for the processor
* Add a session to the Router to prevent updateSeraiKey replaying
This would only happen if an old key was rotated to again, which would require
n-of-n collusion (already ridiculous and a valid fault attributable event). It
just clarifies the formal arguments.
* Add a RouterCommand + SignMachine for producing it to coins/ethereum
* Ethereum which compiles
* Have branch/change/forward return an option
Also defines a UtxoNetwork extension trait for MAX_INPUTS.
* Make external_address exclusively a test fn
* Move the "account" scheduler to "smart contract"
* Remove ABI artifact
* Move refund/forward Plan creation into the Processor
We create forward Plans in the scan path, and need to know their exact fees in
the scan path. This requires adding a somewhat wonky shim_forward_plan method
so we can obtain a Plan equivalent to the actual forward Plan for fee reasons,
yet don't expect it to be the actual forward Plan (which may be distinct if
the Plan pulls from the global state, such as with a nonce).
Also properly types a Scheduler addendum such that the SC scheduler isn't
cramming the nonce to use into the N::Output type.
* Flesh out the Ethereum integration more
* Two commits ago, into the **Scheduler, not Processor
* Remove misc TODOs in SC Scheduler
* Add constructor to RouterCommandMachine
* RouterCommand read, pairing with the prior added write
* Further add serialization methods
* Have the Router's key included with the InInstruction
This does not use the key at the time of the event. This uses the key at the
end of the block for the event. Its much simpler than getting the full event
streams for each, checking when they interlace.
This does not read the state. Every block, this makes a request for every
single key update and simply chooses the last one. This allows pruning state,
only keeping the event tree. Ideally, we'd also introduce a cache to reduce the
cost of the filter (small in events yielded, long in blocks searched).
Since Serai doesn't have any forwarding TXs, nor Branches, nor change, all of
our Plans should solely have payments out, and there's no expectation of a Plan
being made under one key broken by it being received by another key.
* Add read/write to InInstruction
* Abstract the ABI for Call/OutInstruction in ethereum-serai
* Fill out signable_transaction for Ethereum
* Move ethereum-serai to alloy
Resolves#331.
* Use the opaque sol macro instead of generated files
* Move the processor over to the now-alloy-based ethereum-serai
* Use the ecrecover provided by alloy
* Have the SC use nonce for rotation, not session (an independent nonce which wasn't synchronized)
* Always use the latest keys for SC scheduled plans
* get_eventuality_completions for Ethereum
* Finish fleshing out the processor Ethereum integration as needed for serai-processor tests
This doesn't not support any actual deployments, not even the ones simulated by
serai-processor-docker-tests.
* Add alloy-simple-request-transport to the GH workflows
* cargo update
* Clarify a few comments and make one check more robust
* Use a string for 27.0 in .github
* Remove optional from no-longer-optional dependencies in processor
* Add alloy to git deny exception
* Fix no longer optional specification in processor's binaries feature
* Use a version of foundry from 2024
* Correct fetching Bitcoin TXs in the processor docker tests
* Update rustls to resolve RUSTSEC warnings
* Use the monthly nightly foundry, not the deleted daily nightly
* start Router contract
* use calldata for function args
* var name changes
* start testing router contract
* test with and without abi.encode
* cleanup
* why tf isn't tests/utils working
* cleanup tests
* remove unused files
* wip
* fix router contract and tests, add set/update public keys funcs
* impl some Froms
* make execute non-reentrant
* cleanup
* update Router to use ReentrancyGuard
* update contract to use errors, use bitfield in Executed event, minor other fixes
* wip
* fix build issues from merge, tests ok
* Router.sol cleanup
* cleanup, uncomment stuff
* bump ethers.rs version to latest

Moves from concatted Dockerfiles to pseudo-templated Dockerfiles via a dedicated Rust program.
Removes the unmaintained kubernetes, not because we shouldn't have/use it, but because it's unmaintained and needs to be reworked before it's present again.
Replaces the compose with the work in the new orchestrator binary which spawns everything as expected. While this arguably re-invents the wheel, it correctly manages secrets and handles the variadic Dockerfiles.
Also adds an unrelated patch for zstd and simplifies running services a bit by greater utilizing the existing infrastructure.
---
* Delete all Dockerfile fragments, add new orchestator to generate Dockerfiles
Enables greater templating.
Also delete the unmaintained kubernetes folder *for now*. This should be
restored in the future.
* Use Dockerfiles from the orchestator
* Ignore Dockerfiles in the git repo
* Remove CI job to check Dockerfiles are as expected now that they're no longer committed
* Remove old Dockerfiles from repo
* Use Debian for monero-wallet-rpc
* Remove replace_cmds for proper usage of entry-dev
Consolidates ports a bit.
Updates serai-docker-tests from "compose" to "build".
* Only write a new dockerfile if it's distinct
Preserves the updated time metadata.
* Update serai-docker-tests
* Correct the path Dockerfiles are built from
* Correct inclusion of orchestration folder in Docker builds
* Correct debug/release flagging in the cargo command
Apparently, --debug isn't an effective NOP yet an error.
* Correct path used to run the Serai node within a Dockerfile
* Correct path in Monero Dockerfile
* Attempt storing monerod in /usr/bin
* Use sudo to move into /usr/bin in CI
* Correct 18.3.0 to 18.3.1
* Escape * with quotes
* Update deny.toml, ADD orchestration in runtime Dockerfile
* Add --detach to the Monero GH CI
* Diversify dockerfiles by network
* Fixes to network-diversified orchestration
* Bitcoin and Monero testnet scripts
* Permissions and tweaks
* Flatten scripts folders
* Add missing folder specification to Monero Dockerfile
* Have monero-wallet-rpc specify the monerod login
* Have the Docker CMD specify env variables inserted at time of Dockerfile generation
They're overrideable with the global enviornment as for tests. This enables
variable generation in orchestrator and output to productionized Docker files
without creating a life-long file within the Docker container.
* Don't add Dockerfiles into Docker containers now that they have secrets
Solely add the source code for them as needed to satisfy the workspace bounds.
* Download arm64 Monero on arm64
* Ensure constant host architecture when reproducibly building the wasm
Host architecture, for some reason, can effect the generated code despite the
target architecture always being foreign to the host architecture.
* Randomly generate infrastructure keys
* Have orchestrator generate a key, be able to create/start containers
* Ensure bash is used over sh
* Clean dated docs
* Change how quoting occurs
* Standardize to sh
* Have Docker test build the dev Dockerfiles
* Only key_gen once
* cargo update
Adds a patch for zstd and reconciles the breaking nightly change which just
occurred.
* Use a dedicated network for Serai
Also fixes SERAI_HOSTNAME passed to coordinator.
* Support providing a key over the env for the Serai node
* Enable and document running daemons for tests via serai-orchestrator
Has running containers under the dev network port forward the RPC ports.
* Use volumes for bitcoin/monero
* Use bitcoin's run.sh in GH CI
* Only use the volume for testnet (not dev)
* Remove unused brew packages on macOS
* Remove reference to Docker in macOS CI
* Remove gems, explicitly test Intel and m1 macOS
* Allow gem to error since it still mostly runs
* Specifically use bash as a shell to try and get rustup to work on Windows
* Use bash for the call to echo
* Add macOS clippy
* Debug why git diff failed
* Restore macos-latest to matrix
* Allow whitespace before the fact 0 lines were modified
* Add LC_ALL env variable to grep
* Replace usage of -P with -e
* Add windows clippy
* Adjust build-dependencies for Linux/Windows
* Specifically use bash as a shell to try and get rustup to work on Windows
* Use bash for the call to echo
* Remove dtolnay's rust-toolchain action
I believe our rust-toolchain.toml handles its use case exactly.
I don't believe this'll work, as it'd require rustup install a cargo stub
before any toolchain is installed, yet I want to confirm it doesn't.
* Place quotes around nightly toolchain version
* Put toolchain before options to resolve what appears to be a bug in rustup's help strings
* Add wasm32-unkknown-unknown to clippy workflow
