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

* 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
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.
---

* 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

* Route validators for any active set through sc-authority-discovery
Additionally adds an RPC route to retrieve their P2P addresses.

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

Resolves#353
Implements code such that:
- 80% of validators (by stake) must be in favor of a signal for the network to
be
- 80% of networks (by stake) must be in favor of a signal for it to be locked
in
- After a signal has been locked in for two weeks, the network halts
The intention is to:
1) Not allow validators to unilaterally declare new consensus rules.
No method of declaring new consensus rules is provided by this pallet. Solely a
way to deprecate the current rules, with a signaled for successor. All nodes
must then individually decide whether or not to download and run a new node
which has new rules, and if so, which rules.
2) Not place blobs on chain.
Even if they'd be reproducible, it's just a lot of data to chuck on the
blockchain.
* initial implementation
* add function to get a balance of an account
* add support for multiple coins
* rename pallet to "coins-pallet"
* replace balances, assets and tokens pallet with coins pallet in runtime
* add total supply info
* update client side for new Coins pallet
* handle fees
* bug fixes
* Update FeeAccount test
* Fmt
* fix pr comments
* remove extraneous Imbalance type
* Minor tweaks

* Design and document a multisig rotation flow
* Make Scanner::eventualities a HashMap so it's per-key
* Don't drop eventualities, always follow through on them
Technical improvements made along the way.
* Start creating an isolate object to manage multisigs, which doesn't require being a signer
Removes key from SubstrateBlock.
* Move Scanner/Scheduler under multisigs
* Move Batch construction into MultisigManager
* Clarify "should" in Multisig Rotation docs
* Add block_number to MultisigManager, as it controls the scanner
* Move sign_plans into MultisigManager
Removes ThresholdKeys from prepare_send.
* Make SubstrateMutable an alias for MultisigManager
* Rewrite Multisig Rotation
The prior scheme had an exploit possible where funds were sent to the old
multisig, then burnt on Serai to send from the new multisig, locking liquidity
for 6 hours. While a fee could be applied to stragglers, to make this attack
unprofitable, the newly described scheme avoids all this.
* Add mini
mini is a miniature version of Serai, emphasizing Serai's nature as a
collection of independent clocks. The intended use is to identify race
conditions and prove protocols are comprehensive regarding when certain clocks
tick.
This uses loom, a prior candidate for evaluating the processor/coordinator as
free of race conditions (#361).
* Use mini to prove a race condition in the current multisig rotation docs, and prove safety of alternatives
Technically, the prior commit had mini prove the race condition.
The docs currently say the activation block of the new multisig is the block
after the next Batch's. If the two next Batches had already entered the
mempool, prior to set_keys being called, the second next Batch would be
expected to contain the new key's data yet fail to as the key wasn't public
when the Batch was actually created.
The naive solution is to create a Batch, publish it, wait until it's included,
and only then scan the next block. This sets a bound of
`Batch publication time < block time`. Optimistically, we can publish a Batch
in 24s while our shortest block time is 2m. Accordingly, we should be fine with
the naive solution which doesn't take advantage of throughput. #333 may
significantly change latency however and require an algorithm whose throughput
exceeds the rate of blocks created.
In order to re-introduce parallelization, enabling throughput, we need to
define a safe range of blocks to scan without Serai ordering the first one.
mini demonstrates safety of scanning n blocks Serai hasn't acknowledged, so
long as the first is scanned before block n+1 is (shifting the n-block window).
The docs will be updated next, to reflect this.
* Fix Multisig Rotation
I believe this is finally good enough to be final.
1) Fixes the race condition present in the prior document, as demonstrated by
mini.
`Batch`s for block `n` and `n+1`, may have been in the mempool when a
multisig's activation block was set to `n`. This would cause a potentially
distinct `Batch` for `n+1`, despite `n+1` already having a signed `Batch`.
2) Tightens when UIs should use the new multisig to prevent eclipse attacks,
and protection against `Batch` publication delays.
3) Removes liquidity fragmentation by tightening flow/handling of latency.
4) Several clarifications and documentation of reasoning.
5) Correction of "prior multisig" to "all prior multisigs" regarding historical
verification, with explanation why.
* Clarify terminology in mini
Synchronizes it from my original thoughts on potential schema to the design
actually created.
* Remove most of processor's README for a reference to docs/processor
This does drop some misc commentary, though none too beneficial. The section on
scanning, deemed sufficiently beneficial, has been moved to a document and
expanded on.
* Update scanner TODOs in line with new docs
* Correct documentation on Bitcoin::Block::time, and Block::time
* Make the scanner in MultisigManager no longer public
* Always send ConfirmKeyPair, regardless of if in-set
* Cargo.lock changes from a prior commit
* Add a policy document on defining a Canonical Chain
I accidentally committed a version of this with a few headers earlier, and this
is a proper version.
* Competent MultisigManager::new
* Update processor's comments
* Add mini to copied files
* Re-organize Scanner per multisig rotation document
* Add RUST_LOG trace targets to e2e tests
* Have the scanner wait once it gets too far ahead
Also bug fixes.
* Add activation blocks to the scanner
* Split received outputs into existing/new in MultisigManager
* Select the proper scheduler
* Schedule multisig activation as detailed in documentation
* Have the Coordinator assert if multiple `Batch`s occur within a block
While the processor used to have ack_up_to_block, enabling skips in the block
acked, support for this was removed while reworking it for multiple multisigs.
It should happen extremely infrequently.
While it would still be beneficial to have, if multiple `Batch`s could occur
within a block (with the complexity here not being worth adding that ban as a
policy), multiple `Batch`s were blocked for DoS reasons.
* Schedule payments to the proper multisig
* Correct >= to <
* Use the new multisig's key for change on schedule
* Don't report External TXs to prior multisig once deprecated
* Forward from the old multisig to the new one at all opportunities
* Move unfulfilled payments in queue from prior to new multisig
* Create MultisigsDb, splitting it out of MainDb
Drops the call to finish_signing from the Signer. While this will cause endless
re-attempts, the Signer will still consider them completed and drop them,
making this an O(n) cost at boot even if we did nothing from here.
The MultisigManager should call finish_signing once the Scanner completes the
Eventuality.
* Don't check Scanner-emitted completions, trust they are completions
Prevents needing to use async code to mark the completion and creates a
fault-free model. The current model, on fault, would cause a lack of marked
completion in the signer.
* Fix a possible panic in the processor
A shorter-chain reorg could cause this assert to trip. It's fixed by
de-duplicating the data, as the assertion checked consistency. Without the
potential for inconsistency, it's unnecessary.
* Document why an existing TODO isn't valid
* Change when we drop payments for being to the change address
The earlier timing prevents creating Plans solely to the branch address,
causing the payments to be dropped, and the TX to become an effective
aggregation TX.
* Extensively document solutions to Eventualities being potentially created after having already scanned their resolutions
* When closing, drop External/Branch outputs which don't cause progress
* Properly decide if Change outputs should be forward or not when closing
This completes all code needed to make the old multisig have a finite lifetime.
* Commentary on forwarding schemes
* Provide a 1 block window, with liquidity fragmentation risks, due to latency
On Bitcoin, this will be 10 minutes for the relevant Batch to be confirmed. On
Monero, 2 minutes. On Ethereum, ~6 minutes.
Also updates the Multisig Rotation document with the new forwarding plan.
* Implement transaction forwarding from old multisig to new multisig
Identifies a fault where Branch outputs which shouldn't be dropped may be, if
another output fulfills their next step. Locking Branch fulfillment down to
only Branch outputs is not done in this commit, but will be in the next.
* Only let Branch outputs fulfill branches
* Update TODOs
* Move the location of handling signer events to avoid a race condition
* Avoid a deadlock by using a RwLock on a single txn instead of two txns
* Move Batch ID out of the Scanner
* Increase from one block of latency on new keys activation to two
For Monero, this offered just two minutes when our latency to publish a Batch
is around a minute already. This does increase the time our liquidity can be
fragmented by up to 20 minutes (Bitcoin), yet it's a stupid attack only
possible once a week (when we rotate). Prioritizing normal users' transactions
not being subject to forwarding is more important here.
Ideally, we'd not do +2 blocks yet plus `time`, such as +10 minutes, making
this agnostic of the underlying network's block scheduling. This is a
complexity not worth it.
* Split MultisigManager::substrate_block into multiple functions
* Further tweaks to substrate_block
* Acquire a lock on all Scanner operations after calling ack_block
Gives time to call register_eventuality and initiate signing.
* Merge sign_plans into substrate_block
Also ensure the Scanner's lock isn't prematurely released.
* Use a HashMap to pass to-be-forwarded instructions, not the DB
* Successfully determine in ClosingExisting
* Move from 2 blocks of latency when rotating to 10 minutes
Superior as noted in 6d07af92ce10cfd74c17eb3400368b0150eb36d7, now trivial to
implement thanks to prior commit.
* Add note justifying measuring time in blocks when rotating
* Implement delaying of outputs received early to the new multisig per specification
* Documentation on why Branch outputs don't have the race condition concerns Change do
Also ensures 6 hours is at least N::CONFIRMATIONS, for sanity purposes.
* Remove TODO re: sanity checking Eventualities
We sanity check the Plan the Eventuality is derived from, and the Eventuality
is handled moments later (in the same file, with a clear call path). There's no
reason to add such APIs to Eventualities for a sanity check given that.
* Add TODO(now) for TODOs which must be done in this branch
Also deprecates a pair of TODOs to TODO2, and accepts the flow of the Signer
having the Eventuality.
* Correct errors in potential/future flow descriptions
* Accept having a single Plan Vec
Per the following code consuming it, there's no benefit to bifurcating it by
key.
* Only issue sign_transaction on boot for the proper signer
* Only set keys when participating in their construction
* Misc progress
Only send SubstrateBlockAck when we have a signer, as it's only used to tell
the Tributary of what Plans are being signed in response to this block.
Only immediately sets substrate_signer if session is 0.
On boot, doesn't panic if we don't have an active key (as we wouldn't if only
joining the next multisig). Continues.
* Correctly detect and set retirement block
Modifies the retirement block from first block meeting requirements to block
CONFIRMATIONS after.
Adds an ack flow to the Scanner's Confirmed event and Block event to accomplish
this, which may deadlock at this time (will be fixed shortly).
Removes an invalid await (after a point declared unsafe to use await) from
MultisigsManager::next_event.
* Remove deadlock in multisig_completed and document alternative
The alternative is simpler, albeit less efficient. There's no reason to adopt
it now, yet perhaps if it benefits modeling?
* Handle the final step of retirement, dropping the old key and setting new to existing
* Remove TODO about emitting a Block on every step
If we emit on NewAsChange, we lose the purpose of the NewAsChange period.
The only concern is if we reach ClosingExisting, and nothing has happened, then
all coins will still be in the old multisig until something finally does. This
isn't a problem worth solving, as it's latency under exceptional dead time.
* Add TODO about potentially not emitting a Block event for the reitrement block
* Restore accidentally deleted CI file
* Pair of slight tweaks
* Add missing if statement
* Disable an assertion when testing
One of the test flows currently abuses the Scanner in a way triggering it.
Adds 17 new crates, which I'm extremely unhappy about. Unfortunately, it's
needed to resolve a security issue (RUSTSEC-2023-0052) and is inevitable.
Closes#355.
Achieves three notable updates.
1) Resolves RUSTSEC-2022-0093 by updating libp2p-identity.
2) Removes 3 old rand crates via updating ed25519-dalek (a dependency of
libp2p-identity).
3) Sets serde_derive to 1.0.171 via updating to time 0.3.26 which pins at up to
1.0.171.
The last one is the most important. The former two are niceties.
serde_derive, since 1.0.171, ships a non-reproducible binary blob in what's a
complete compromise of supply chain security. This is done in order to reduce
compile times, yet also for the maintainer of serde (dtolnay) to leverage
serde's position as the 8th most downloaded crate to attempt to force changes
to the Rust build pipeline.
While dtolnay's contributions to Rust are respectable, being behind syn, quote,
and proc-macro2 (the top three crates by downloads), along with thiserror,
anyhow, async-trait, and more (I believe also being part of the Rust project),
they have unfortunately decided to refuse to listen to the community on this
issue (or even engage with counter-commentary). Given their political agenda
they seem to try to be accomplishing with force, I'd go as far as to call their
actions terroristic (as they're using the threat of the binary blob as
justification for cargo to ship 'proper' support for binary blobs).
This is arguably representative of dtolnay's past work on watt. watt was a wasm
interpreter to execute a pre-compiled proc macro. This would save the compile
time of proc macros, yet sandbox it so a full binary did not have to be run.
Unfortunately, watt (while decreasing compile times) fails to be a valid
solution to supply chain security (without massive ecosystem changes). It never
implemented reproducible builds for its wasm blobs, and a malicious wasm blob
could still fundamentally compromise a project. The only solution for an end
user to achieve a secure pipeline would be to locally build the project,
verifying the blob aligns, yet doing so would negate all advantages of the
blob.
dtolnay also seems to be giving up their role as a FOSS maintainer given that
serde no longer works in several environments. While FOSS maintainers are not
required to never implement breaking changes, the version number is still 1.0.
While FOSS maintainers are not required to follow semver, releasing a very
notable breaking change *without a new version number* in an ecosystem which
*does follow semver*, then refusing to acknowledge bugs as bugs with their work
does meet my personal definition of "not actively maintaining their existing
work". Maintenance would be to fix bugs, not introduce and ignore.
For now, serde > 1.0.171 has been banned. In the future, we may host a fork
without the blobs (yet with the patches). It may be necessary to ban all of
dtolnay's maintained crates, if they continue to force their agenda as such,
yet I hope this may be resolved within the next week or so.

This includes several reports of various workflows being broken.
https://github.com/serde-rs/serde/issues/2538#issuecomment-1682519944
dtolnay commenting that security should be resolved via Rust toolchain edits,
not via their own work being secure. This is why I say they're trying to
leverage serde in a political game.
https://github.com/serde-rs/serde/issues/2526 - Usage via git broken
dtolnay explicitly asks the submitting user if they'd be willing to advocate
for changes to Rust rather than actually fix the issue they created. This is
further political arm wrestling.

* Move monero-serai from std to std-shims, where possible
* no-std fixes
* Make the HttpRpc its own feature, thiserror only on std
* Drop monero-rs's epee for a homegrown one
We only need it for a single function. While I tried jeffro's, it didn't work
out of the box, had three unimplemented!s, and is no where near viable for
no_std.
Fixes#182, though should be further tested.
* no-std monero-serai
* Allow base58-monero via git
* cargo fmt
* Partial move to ff 0.13
It turns out the newly released k256 0.12 isn't on ff 0.13, preventing further
work at this time.
* Update all crates to work on ff 0.13
The provided curves still need to be expanded to fit the new API.
* Finish adding dalek-ff-group ff 0.13 constants
* Correct FieldElement::product definition
Also stops exporting macros.
* Test most new parts of ff 0.13
* Additionally test ff-group-tests with BLS12-381 and the pasta curves
We only tested curves from RustCrypto. Now we test a curve offered by zk-crypto,
the group behind ff/group, and the pasta curves, which is by Zcash (though
Zcash developers are also behind zk-crypto).
* Finish Ed448
Fully specifies all constants, passes all tests in ff-group-tests, and finishes moving to ff-0.13.
* Add RustCrypto/elliptic-curves to allowed git repos
Needed due to k256/p256 incorrectly defining product.
* Finish writing ff 0.13 tests
* Add additional comments to dalek
* Further comments
* Update ethereum-serai to ff 0.13
Updates to polkadot-v0.9.40, with a variety of dependency updates accordingly.
Substrate thankfully now uses k256 0.13, pathing the way for #256. We couldn't
upgrade to polkadot-v0.9.40 without this due to polkadot-v0.9.40 having
fundamental changes to syncing. While we could've updated tendermint, it's not
worth the continued development effort given its inability to work with
multiple validator sets.
Purges sc-tendermint. Keeps tendermint-machine for #163.
Closes#137, #148, #157, #171. #96 and #99 should be re-scoped/clarified. #134
and #159 also should be clarified. #169 is also no longer a priority since
we're only considering temporal deployments of tendermint. #170 also isn't
since we're looking at effectively sharded validator sets, so there should
be no singular large set needing high performance.
The original intent was to use inherent transactions to prevent needing to vote
on-chain, which would spam the chain with worthless votes. Inherent
transactions, and our Tendermint library, would use the BFT's processs voting
to also vote on all included transactions. This perfectly collapses integrity
voting creating *no additional on-chain costs*.
Unfortunately, this led to issues such as #6, along with questions of validator
scalability when all validators are expencted to participate in consensus (in
order to vote on if the included instructions are valid). This has been
summarized in #241.
With this change, we can remove Tendermint from Substrate. This greatly
decreases our complexity. While I'm unhappy with the amount of time spent on
it, just to reach this conclusion, thankfully tendermint-machine itself is
still usable for #163. This also has reached a tipping point recently as the
polkadot-v0.9.40 branch of substrate changed how syncing works, requiring
further changes to sc-tendermint. These have no value if we're just going to
get rid of it later, due to fundamental design issues, yet I would like to
keep Substrate updated.
This should be followed by moving back to GRANDPA, enabling closing most open
Tendermint issues.
Please note the current in-instructions-pallet does not actually verify the
included signature yet. It's marked TODO, despite this bing critical.
* Initial work on a message box
* Finish message-box (untested)
* Expand documentation
* Embed the recipient in the signature challenge
Prevents a message from A -> B from being read as from A -> C.
* Update documentation by bifurcating sender/receiver
* Panic on receiving an invalid signature
If we've received an invalid signature in an authenticated system, a
service is malicious, critically faulty (equivalent to malicious), or
the message layer has been compromised (or is otherwise critically
faulty).
Please note a receiver who handles a message they shouldn't will trigger
this. That falls under being critically faulty.
* Documentation and helper methods
SecureMessage::new and SecureMessage::serialize.
Secure Debug for MessageBox.
* Have SecureMessage not be serialized by default
Allows passing around in-memory, if desired, and moves the error from
decrypt to new (which performs deserialization).
Decrypt no longer has an error since it panics if given an invalid
signature, due to this being intranet code.
* Explain and improve nonce handling
Includes a missing zeroize call.
* Rebase to latest develop
Updates to transcript 0.2.0.
* Add a test for the MessageBox
* Export PrivateKey and PublicKey
* Also test serialization
* Add a key_gen binary to message_box
* Have SecureMessage support Serde
* Add encrypt_to_bytes and decrypt_from_bytes
* Support String ser via base64
* Rename encrypt/decrypt to encrypt_bytes/decrypt_to_bytes
* Directly operate with values supporting Borsh
* Use bincode instead of Borsh
By staying inside of serde, we'll support many more structs. While
bincode isn't canonical, we don't need canonicity on an authenticated,
internal system.
* Turn PrivateKey, PublicKey into structs
Uses Zeroizing for the PrivateKey per #150.
* from_string functions intended for loading from an env
* Use &str for PublicKey from_string (now from_str)
The PrivateKey takes the String to take ownership of its memory and
zeroize it. That isn't needed with PublicKeys.
* Finish updating from develop
* Resolve warning
* Use ZeroizingAlloc on the key_gen binary
* Move message-box from crypto/ to common/
* Move key serialization functions to ser
* add/remove functions in MessageBox
* Implement Hash on dalek_ff_group Points
* Make MessageBox generic to its key
Exposes a &'static str variant for internal use and a RistrettoPoint
variant for external use.
* Add Private to_string as deprecated
Stub before more competent tooling is deployed.
* Private to_public
* Test both Internal and External MessageBox, only use PublicKey in the pub API
* Remove panics on invalid signatures
Leftover from when this was solely internal which is now unsafe.
* Chicken scratch a Scanner task
* Add a write function to the DKG library
Enables writing directly to a file.
Also modifies serialize to return Zeroizing<Vec<u8>> instead of just Vec<u8>.
* Make dkg::encryption pub
* Remove encryption from MessageBox
* Use a 64-bit block number in Substrate
We use a 64-bit block number in general since u32 only works for 120 years
(with a 1 second block time). As some chains even push the 1 second threshold,
especially ones based on DAG consensus, this becomes potentially as low as 60
years.
While that should still be plenty, it's not worth wondering/debating. Since
Serai uses 64-bit block numbers elsewhere, this ensures consistency.
* Misc crypto lints
* Get the scanner scratch to compile
* Initial scanner test
* First few lines of scheduler
* Further work on scheduler, solidify API
* Define Scheduler TX format
* Branch creation algorithm
* Document when the branch algorithm isn't perfect
* Only scanned confirmed blocks
* Document Coin
* Remove Canonical/ChainNumber from processor
The processor should be abstracted from canonical numbers thanks to the
coordinator, making this unnecessary.
* Add README documenting processor flow
* Use Zeroize on substrate primitives
* Define messages from/to the processor
* Correct over-specified versioning
* Correct build re: in_instructions::primitives
* Debug/some serde in crypto/
* Use a struct for ValidatorSetInstance
* Add a processor key_gen task
Redos DB handling code.
* Replace trait + impl with wrapper struct
* Add a key confirmation flow to the key gen task
* Document concerns on key_gen
* Start on a signer task
* Add Send to FROST traits
* Move processor lib.rs to main.rs
Adds a dummy main to reduce clippy dead_code warnings.
* Further flesh out main.rs
* Move the DB trait to AsRef<[u8]>
* Signer task
* Remove a panic in bitcoin when there's insufficient funds
Unchecked underflow.
* Have Monero's mine_block mine one block, not 10
It was initially a nicety to deal with the 10 block lock. C::CONFIRMATIONS
should be used for that instead.
* Test signer
* Replace channel expects with log statements
The expects weren't problematic and had nicer code. They just clutter test
output.
* Remove the old wallet file
It predates the coordinator design and shouldn't be used.
* Rename tests/scan.rs to tests/scanner.rs
* Add a wallet test
Complements the recently removed wallet file by adding a test for the scanner,
scheduler, and signer together.
* Work on a run function
Triggers a clippy ICE.
* Resolve clippy ICE
The issue was the non-fully specified lambda in signer.
* Add KeyGenEvent and KeyGenOrder
Needed so we get KeyConfirmed messages from the key gen task.
While we could've read the CoordinatorMessage to see that, routing through the
key gen tasks ensures we only handle it once it's been successfully saved to
disk.
* Expand scanner test
* Clarify processor documentation
* Have the Scanner load keys on boot/save outputs to disk
* Use Vec<u8> for Block ID
Much more flexible.
* Panic if we see the same output multiple times
* Have the Scanner DB mark itself as corrupt when doing a multi-put
This REALLY should be a TX. Since we don't have a TX API right now, this at
least offers detection.
* Have DST'd DB keys accept AsRef<[u8]>
* Restore polling all signers
Writes a custom future to do so.
Also loads signers on boot using what the scanner claims are active keys.
* Schedule OutInstructions
Adds a data field to Payment.
Also cleans some dead code.
* Panic if we create an invalid transaction
Saves the TX once it's successfully signed so if we do panic, we have a copy.
* Route coordinator messages to their respective signer
Requires adding key to the SignId.
* Send SignTransaction orders for all plans
* Add a timer to retry sign_plans when prepare_send fails
* Minor fmt'ing
* Basic Fee API
* Move the change key into Plan
* Properly route activation_number
* Remove ScannerEvent::Block
It's not used under current designs
* Nicen logs
* Add utilities to get a block's number
* Have main issue AckBlock
Also has a few misc lints.
* Parse instructions out of outputs
* Tweak TODOs and remove an unwrap
* Update Bitcoin max input/output quantity
* Only read one piece of data from Monero
Due to output randomization, it's infeasible.
* Embed plan IDs into the TXs they create
We need to stop attempting signing if we've already signed a protocol. Ideally,
any one of the participating signers should be able to provide a proof the TX
was successfully signed. We can't just run a second signing protocol though as
a single malicious signer could complete the TX signature, and publish it,
yet not complete the secondary signature.
The TX itself has to be sufficient to show that the TX matches the plan. This
is done by embedding the ID, so matching addresses/amounts plans are
distinguished, and by allowing verification a TX actually matches a set of
addresses/amounts.
For Monero, this will need augmenting with the ephemeral keys (or usage of a
static seed for them).
* Don't use OP_RETURN to encode the plan ID on Bitcoin
We can use the inputs to distinguih identical-output plans without issue.
* Update OP_RETURN data access
It's not required to be the last output.
* Add Eventualities to Monero
An Eventuality is an effective equivalent to a SignableTransaction. That is
declared not by the inputs it spends, yet the outputs it creates.
Eventualities are also bound to a 32-byte RNG seed, enabling usage of a
hash-based identifier in a SignableTransaction, allowing multiple
SignableTransactions with the same output set to have different Eventualities.
In order to prevent triggering the burning bug, the RNG seed is hashed with
the planned-to-be-used inputs' output keys. While this does bind to them, it's
only loosely bound. The TX actually created may use different inputs entirely
if a forgery is crafted (which requires no brute forcing).
Binding to the key images would provide a strong binding, yet would require
knowing the key images, which requires active communication with the spend
key.
The purpose of this is so a multisig can identify if a Transaction the entire
group planned has been executed by a subset of the group or not. Once a plan
is created, it can have an Eventuality made. The Eventuality's extra is able
to be inserted into a HashMap, so all new on-chain transactions can be
trivially checked as potential candidates. Once a potential candidate is found,
a check involving ECC ops can be performed.
While this is arguably a DoS vector, the underlying Monero blockchain would
need to be spammed with transactions to trigger it. Accordingly, it becomes
a Monero blockchain DoS vector, when this code is written on the premise
of the Monero blockchain functioning. Accordingly, it is considered handled.
If a forgery does match, it must have created the exact same outputs the
multisig would've. Accordingly, it's argued the multisig shouldn't mind.
This entire suite of code is only necessary due to the lack of outgoing
view keys, yet it's able to avoid an interactive protocol to communicate
key images on every single received output.
While this could be locked to the multisig feature, there's no practical
benefit to doing so.
* Add support for encoding Monero address to instructions
* Move Serai's Monero address encoding into serai-client
serai-client is meant to be a single library enabling using Serai. While it was
originally written as an RPC client for Serai, apps actually using Serai will
primarily be sending transactions on connected networks. Sending those
transactions require proper {In, Out}Instructions, including proper address
encoding.
Not only has address encoding been moved, yet the subxt client is now behind
a feature. coin integrations have their own features, which are on by default.
primitives are always exposed.
* Reorganize file layout a bit, add feature flags to processor
* Tidy up ETH Dockerfile
* Add Bitcoin address encoding
* Move Bitcoin::Address to serai-client's
* Comment where tweaking needs to happen
* Add an API to check if a plan was completed in a specific TX
This allows any participating signer to submit the TX ID to prevent further
signing attempts.
Also performs some API cleanup.
* Minimize FROST dependencies
* Use a seeded RNG for key gen
* Tweak keys from Key gen
* Test proper usage of Branch/Change addresses
Adds a more descriptive error to an error case in decoys, and pads Monero
payments as needed.
* Also test spending the change output
* Add queued_plans to the Scheduler
queued_plans is for payments to be issued when an amount appears, yet the
amount is currently pre-fee. One the output is actually created, the
Scheduler should be notified of the amount it was created with, moving from
queued_plans to plans under the actual amount.
Also tightens debug_asserts to asserts for invariants which may are at risk of
being exclusive to prod.
* Add missing tweak_keys call
* Correct decoy selection height handling
* Add a few log statements to the scheduler
* Simplify test's get_block_number
* Simplify, while making more robust, branch address handling in Scheduler
* Have fees deducted from payments
Corrects Monero's handling of fees when there's no change address.
Adds a DUST variable, as needed due to 1_00_000_000 not being enough to pay
its fee on Monero.
* Add comment to Monero
* Consolidate BTC/XMR prepare_send code
These aren't fully consolidated. We'd need a SignableTransaction trait for
that. This is a lot cleaner though.
* Ban integrated addresses
The reasoning why is accordingly documented.
* Tidy TODOs/dust handling
* Update README TODO
* Use a determinisitic protocol version in Monero
* Test rebuilt KeyGen machines function as expected
* Use a more robust KeyGen entropy system
* Add DB TXNs
Also load entropy from env
* Add a loop for processing messages from substrate
Allows detecting if we're behind, and if so, waiting to handle the message
* Set Monero MAX_INPUTS properly
The previous number was based on an old hard fork. With the ring size having
increased, transactions have since got larger.
* Distinguish TODOs into TODO and TODO2s
TODO2s are for after protonet
* Zeroize secret share repr in ThresholdCore write
* Work on Eventualities
Adds serialization and stops signing when an eventuality is proven.
* Use a more robust DB key schema
* Update to {k, p}256 0.12
* cargo +nightly clippy
* cargo update
* Slight message-box tweaks
* Update to recent Monero merge
* Add a Coordinator trait for communication with coordinator
* Remove KeyGenHandle for just KeyGen
While KeyGen previously accepted instructions over a channel, this breaks the
ack flow needed for coordinator communication. Now, KeyGen is the direct object
with a handle() function for messages.
Thankfully, this ended up being rather trivial for KeyGen as it has no
background tasks.
* Add a handle function to Signer
Enables determining when it's finished handling a CoordinatorMessage and
therefore creating an acknowledgement.
* Save transactions used to complete eventualities
* Use a more intelligent sleep in the signer
* Emit SignedTransaction with the first ID *we can still get from our node*
* Move Substrate message handling into the new coordinator recv loop
* Add handle function to Scanner
* Remove the plans timer
Enables ensuring the ordring on the handling of plans.
* Remove the outputs function which panicked if a precondition wasn't met
The new API only returns outputs upon satisfaction of the precondition.
* Convert SignerOrder::SignTransaction to a function
* Remove the key_gen object from sign_plans
* Refactor out get_fee/prepare_send into dedicated functions
* Save plans being signed to the DB
* Reload transactions being signed on boot
* Stop reloading TXs being signed (and report it to peers)
* Remove message-box from the processor branch
We don't use it here yet.
* cargo +nightly fmt

* Handle most clippy lints on bitcoin
Doesn't handle the unused transcript due to pending cryptographic considerations.
* Rearrange imports and clippy tests
* Misc processor lint
* Update deny.toml
* Remove unnecessary RPC code
* updated test_send
* added bitcoin ci & updated test-dependencies yml
* fixed bitcoin ci
* updated bitcoin ci yml
* Remove mining from the bitcoin/monero docker files
The tests should control block production in order to test various
circumstances. The automatic mining disrupts assumptions made in testing. Since
we're now using the Bitcoin docker container for testing...
* Multiple fixes to the Bitcoin processor
Doesn't unwrap on RPC errors. Returns the expected connection error.
Fee calculation has a random - 1. This has been removed.
Supports the change address being an Option, as it is. This should not have
been blindly unwrapped.
* Remove unnecessary RPC code
* Further RPC simplifications
* Simplify Bitcoin action
It should not be mining.
* cargo fmt
* Finish RPC simplifications
* Run bitcoind as a daemon
* Remove the requirement on txindex
Saves tens of GB.
Also has attempt_send no longer return a list of outputs. That's incompatible
with this and only relevant to old scheduling designs.
* Remove number from Bitcoin SignableTransaction
Monero requires the current block number for decoy selection. Bitcoin doesn't
have a use.
* Ban coinbase transactions
These are burdened by maturity, so it's critically flawed to support them.
This causes the test_send function to fail as its working was premised on
a coinbase output. While it does make an actual output, it had insufficient
funds for the test's expectations due to regtest halving every 150 blocks.
In order to workaround this, the test will invalidate any existing chain,
offering a fresh start.
Also removes test_get_spendables and simplifies test_send.
* Various simplifications
Modifies SpendableOutput further to not require RPC calls at time of sign.
Removes the need to have get_transaction in the RPC.
* Clean prepare_send
* Update the Bitcoin TransactionMachine to output a Transaction
* Bitcoin TransactionMachine simplifications
* Update XOnly key handling
* Use a single sighash cache
* Move tweak_keys
* Remove unnecessary PSBT sets
* Restore removed newlines
* Other newlines
* Replace calculate_weight's custom math with a dummy TX serialize
* Move BTC TX construction code from processor to bitcoin
* Rename transactions.rs to wallet.rs
* Remove unused crate
* Note TODO
* Clean bitcoin signature test
* Make unit test out of BTC FROST signing test
* Final lint
* Remove usage of PartiallySignedTransaction

* Use Monero-compatible additional TX keys
This still sends a fingerprinting flare up if you send to a subaddress which
needs to be fixed. Despite that, Monero no should no longer fail to scan TXs
from monero-serai regarding additional keys.
Previously it failed becuase we supplied one key as THE key, and n-1 as
additional. Monero expects n for additional.
This does correctly select when to use THE key versus when to use the additional
key when sending. That removes the ability for recipients to fingerprint
monero-serai by receiving to a standard address yet needing to use an additional
key.
* Add tokens_primitives
Moves OutInstruction from in-instructions.
Turns Destination into OutInstruction.
* Correct in-instructions DispatchClass
* Add initial tokens pallet
* Don't allow pallet addresses to equal identity
* Add support for InInstruction::transfer
Requires a cargo update due to modifications made to serai-dex/substrate.
Successfully mints a token to a SeraiAddress.
* Bind InInstructions to an amount
* Add a call filter to the runtime
Prevents worrying about calls to the assets pallet/generally tightens things
up.
* Restore Destination
It was meged into OutInstruction, yet it didn't make sense for OutInstruction
to contain a SeraiAddress.
Also deletes the excessively dated Scenarios doc.
* Split PublicKey/SeraiAddress
Lets us define a custom Display/ToString for SeraiAddress.
Also resolves an oddity where PublicKey would be encoded as String, not
[u8; 32].
* Test burning tokens/retrieving OutInstructions
Modularizes processor_coinUpdates into a shared testing utility.
* Misc lint
* Don't use PolkadotExtrinsicParams
