* De-duplicate Dockerfiles by using a bash file to concatenate common parts
Resolves#375.
Dockerfiles are still committed to the repo to avoid a dependency on bash.
* Add a CI job to confirm the committed dockerfiles are the currently generated ones
* Create dedicated Dockerfiles per processor network
Ensures the compromising of network-specific dependencies doesn't lead to a
compromise of the build process for all processors.
* Dockerfile corrections
* Correct call to build processor Docker image in tests/processor
* Have processor report errors during the DKG to the coordinator
* Add RemoveParticipant, InvalidDkgShare to coordinator
* Route DKG blame around coordinator
* Allow public construction of AdditionalBlameMachine
Necessary for upcoming work on handling DKG blame in the processor and
coordinator.
Additionally fixes a publicly reachable panic when commitments parsed with one
ThresholdParams are used in a machine using another set of ThresholdParams.
Renames InvalidProofOfKnowledge to InvalidCommitments.
* Remove unused error from dleq
* Implement support for VerifyBlame in the processor
* Have coordinator send the processor share message relevant to Blame
* Remove desync between processors reporting InvalidShare and ones reporting GeneratedKeyPair
* Route blame on sign between processor and coordinator
Doesn't yet act on it in coordinator.
* Move txn usage as needed for stable Rust to build
* Correct InvalidDkgShare serialization
ethers-solc was used for a type (now manually specified) and to call out to
solc. Since Foundry was already a documented dependency, a call to it now
handles building.
Removing this single crate removes a total of 17 crates from our dependency
tree. While these may still be around due to Foundry, they at least may not
be.
Further work to remove the requirement on Foundry for solc alone would be
appreciated.
Implements most of #297 to the point I'm fine closing it. The solution
implemented is distinct than originally designed, yet much simpler.
Since we have a fully-linear view of created transactions, we don't have to
per-output track operating costs incurred by that output. We can track it
across the entire Serai system, without hooking into the Eventuality system.
Also updates documentation.
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.
* 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.
The initial TODO was simply to use one ExternalBlock per all batches in the
block. This would require publishing ExternalBlock after the last batch,
requiring knowing the last batch. While we could add such a pipeline, it'd
require:
1) Initial preprocesses using a distinct message from BatchPreprocess
2) An additional message sent after all BatchPreprocess are sent
Unfortunately, both would require tweaks to the SubstrateSigner which aren't
worth the complexity compared to the solution here, at least, not at this time.
While this will cause, if a Tributary is signing a block whose total batch data
exceeds 25 kB, to use multiple transactions which could be optimized out by
'better' local data pipelining, that's an extreme edge case. Given the temporal
nature of each Tributary, it's also an acceptable edge.
This does no longer achieve synchrony over external blocks accordingly. While
signed batches have synchrony, as they embed their block hash, batches being
signed don't have cryptographic synchrony on their contents. This means
validators who are eclipsed may produce invalid shares, as they sign a
different batch. This will be introduced in a follow-up commit.
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.
Due to the ordered message-queue, there's no benefit to multiple emissions as
there's no risk a completion will be missed. If it has yet to be read, sending
another which only be read after isn't helpful.
Simplifies code a decent bit.
It originally wasn't an enum so software which had yet to update before an
integration wouldn't error (as now enums are strictly typed). The strict typing
is preferable though.
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.
There already should only be one validator set operating per network. This
formalizes that. Then, validator sets used to be able to operate over multiple
networks. That is no longer possible.
This formalization increases validator set flexibility while also allowing the
ability to formalize the definiton of tokens (which is necessary to define a
gas asset).
* 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
* Move back common/zalloc
* Update subxt to 0.27
* Zeroize ^1.5, not 1
* Update GitHub workflow
* Remove usage of SignId in completed
This wasn't done prior to be 'leaderless', as now the participant with the
lowest ID has an extra step, yet this is still trivial. There's also notable
performance benefits to not taking the previous dividing approach, which
performed an exp.
* 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

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].

It now re-exports all pallets underneath it.
* Add a function to get storage values to the Serai RPC
* Update substrate/ to latest substrate
* Create a dedicated crate for the Serai RPC
* Remove unused dependencies in substrate/
* Remove unused dependencies in coins/
Out of scope for this branch, just minor and path of least resistance.
* Use substrate/serai/client for the Serai RPC lib
It's a bit out of place, since these client folders are intended for the node to
access pallets and so on. This is for end-users to access Serai as a whole.
In that sense, it made more sense as a top level folder, yet that also felt
out of place.
* Move InInstructions test to serai-client for now
* Final cleanup
* Update deny.toml
* Cargo.lock update from merging develop
* Update nightly
Attempt to work around the current CI failure, which is a Rust ICE.
We previously didn't upgrade due to clippy 10134, yet that's been reverted.
* clippy
* clippy
* fmt
* NativeAddress -> SeraiAddress
* Sec fix on non-provided updates and doc fixes
* Add Serai as a Coin
Necessary in order to swap to Serai.
* Add a BlockHash type, used for batch IDs
* Remove origin from InInstruction
Makes InInstructionTarget. Adds RefundableInInstruction with origin.
* Document storage items in in-instructions
* Rename serai/client/tests/serai.rs to updates.rs
It only tested publishing updates and their successful acceptance.
* Initial work on a Validator Sets pallet
* Update Validator Set docs per current discussions
* Update validator-sets primitives and storage handling
* Add validator set pallets to deny.toml
* Remove Curve from primitives
Since we aren't reusing keys across coins, there's no reason for it to be
on-chain (as previously planned).
* Update documentation on Validator Sets
* Use Twox64Concat instead of Identity
Ensures an even distribution of keys. While xxhash is breakable, these keys
aren't manipulatable by users.
* Add math ops on Amount and define a coin as 1e8
* Add validator-sets to the runtime and remove contracts
Also removes the randomness pallet which was only required by the contracts
runtime.
Does not remove the contracts folder yet so they can still be referred to while
validator-sets is under development. Does remove them from Cargo.toml.
* Add vote function to validator-sets
* Remove contracts folder
* Create an event for the Validator Sets pallet
* Remove old contracts crates from deny.toml
* Remove line from staking branch
* Remove staking from runtime
* Correct VS Config in runtime
* cargo update
* Resolve a few PR comments on terminology
* Create a serai-primitives crate
Move types such as Amount/Coin out of validator-sets. Will be expanded in the
future.
* Fixes for last commit
* Don't reserve set 0
* Further fixes
* Add files meant for last commit
* Remove Staking transfer
This converts proofs from 2n elements to 1+n.
Moves FROST over to it. Additionally, for FROST's binomial nonces, provides
a single DLEq proof (2, not 1+2 elements) by proving the discrete log equality
of their aggregate (with an appropriate binding factor). This may be split back
up depending on later commentary...
* Standardize the DLEq serialization function naming
They mismatched from the rest of the project.
This commit is technically incomplete as it doesn't update the dkg crate.
* Rewrite DKG encryption to enable per-message decryption without side effects
This isn't technically true as I already know a break in this which I'll
correct for shortly.
Does update documentation to explain the new scheme. Required for blame.
* Add a verifiable system for blame during the FROST DKG
Previously, if sent an invalid key share, the participant would realize that
and could accuse the sender. Without further evidence, either the accuser
or the accused could be guilty. Now, the accuser has a proof the accused is
in the wrong.
Reworks KeyMachine to return BlameMachine. This explicitly acknowledges how
locally complete keys still need group acknowledgement before the protocol
can be complete and provides a way for others to verify blame, even after a
locally successful run.
If any blame is cast, the protocol is no longer considered complete-able
(instead aborting). Further accusations of blame can still be handled however.
Updates documentation on network behavior.
Also starts to remove "OnDrop". We now use Zeroizing for anything which should
be zeroized on drop. This is a lot more piece-meal and reduces clones.
* Tweak Zeroizing and Debug impls
Expands Zeroizing to be more comprehensive.
Also updates Zeroizing<CachedPreprocess([u8; 32])> to
CachedPreprocess(Zeroizing<[u8; 32]>) so zeroizing is the first thing done
and last step before exposing the copy-able [u8; 32].
Removes private keys from Debug.
* Fix a bug where adversaries could claim to be using another user's encryption keys to learn their messages
Mentioned a few commits ago, now fixed.
This wouldn't have affected Serai, which aborts on failure, nor any DKG
currently supported. It's just about ensuring the DKG encryption is robust and
proper.
* Finish moving dleq from ser/deser to write/read
* Add tests for dkg blame
* Add a FROST test for invalid signature shares
* Batch verify encrypted messages' ephemeral keys' PoP
* Remove the explicit included participants from FROST
Now, whoever submits preprocesses becomes the signing set. Better separates
preprocess from sign, at the cost of slightly more annoying integrations
(Monero needs to now independently lagrange/offset its key images).
* Support caching preprocesses
Closes https://github.com/serai-dex/serai/issues/40.
I *could* have added a serialization trait to Algorithm and written a ton of
data to disk, while requiring Algorithm implementors also accept such work.
Instead, I moved preprocess to a seeded RNG (Chacha20) which should be as
secure as the regular RNG. Rebuilding from cache simply loads the previously
used Chacha seed, making the Algorithm oblivious to the fact it's being
rebuilt from a cache. This removes any requirements for it to be modified
while guaranteeing equivalency.
This builds on the last commit which delayed determining the signing set till
post-preprocess acquisition. Unfortunately, that commit did force preprocess
from ThresholdView to ThresholdKeys which had visible effects on Monero.
Serai will actually need delayed set determination for #163, and overall,
it remains better, hence it's inclusion.
* Document FROST preprocess caching
* Update ethereum to new FROST
* Fix bug in Monero offset calculation and update processor
Encryption used to be inlined into FROST. When writing the documentation, I
realized it was decently hard to review. It also was antagonistic to other
hosted DKG algorithms by not allowing code re-use.
Encryption is now a standalone module, providing clear boundaries and
reusability.
Additionally, the DKG protocol itself used to use the ciphersuite's specified
hash function (with an HKDF to prevent length extension attacks). Now,
RecommendedTranscript is used to achieve much more robust transcripting and
remove the HKDF dependency. This does add Blake2 into all consumers yet is
preferred for its security properties and ease of review.
* Machine without timeouts
* Time code
* Move substrate/consensus/tendermint to substrate/tendermint
* Delete the old paper doc
* Refactor out external parts to generics
Also creates a dedicated file for the message log.
* Refactor <V, B> to type V, type B
* Successfully compiling
* Calculate timeouts
* Fix test
* Finish timeouts
* Misc cleanup
* Define a signature scheme trait
* Implement serialization via parity's scale codec
Ideally, this would be generic. Unfortunately, the generic API serde
doesn't natively support borsh, nor SCALE, and while there is a serde
SCALE crate, it's old. While it may be complete, it's not worth working
with.
While we could still grab bincode, and a variety of other formats, it
wasn't worth it to go custom and for Serai, we'll be using SCALE almost
everywhere anyways.
* Implement usage of the signature scheme
* Make the infinite test non-infinite
* Provide a dedicated signature in Precommit of just the block hash
Greatly simplifies verifying when syncing.
* Dedicated Commit object
Restores sig aggregation API.
* Tidy README
* Document tendermint
* Sign the ID directly instead of its SCALE encoding
For a hash, which is fixed-size, these should be the same yet this helps
move past the dependency on SCALE. It also, for any type where the two
values are different, smooths integration.
* Litany of bug fixes
Also attempts to make the code more readable while updating/correcting
documentation.
* Remove async recursion
Greatly increases safety as well by ensuring only one message is
processed at once.
* Correct timing issues
1) Commit didn't include the round, leaving the clock in question.
2) Machines started with a local time, instead of a proper start time.
3) Machines immediately started the next block instead of waiting for
the block time.
* Replace MultiSignature with sr25519::Signature
* Minor SignatureScheme API changes
* Map TM SignatureScheme to Substrate's sr25519
* Initial work on an import queue
* Properly use check_block
* Rename import to import_queue
* Implement tendermint_machine::Block for Substrate Blocks
Unfortunately, this immediately makes Tendermint machine capable of
deployment as crate since it uses a git reference. In the future, a
Cargo.toml patch section for serai/substrate should be investigated.
This is being done regardless as it's the quickest way forward and this
is for Serai.
* Dummy Weights
* Move documentation to the top of the file
* Move logic into TendermintImport itself
Multiple traits exist to verify/handle blocks. I'm unsure exactly when
each will be called in the pipeline, so the easiest solution is to have
every step run every check.
That would be extremely computationally expensive if we ran EVERY check,
yet we rely on Substrate for execution (and according checks), which are
limited to just the actual import function.
Since we're calling this code from many places, it makes sense for it to
be consolidated under TendermintImport.
* BlockImport, JustificationImport, Verifier, and import_queue function
* Update consensus/lib.rs from PoW to Tendermint
Not possible to be used as the previous consensus could. It will not
produce blocks nor does it currenly even instantiate a machine. This is
just he next step.
* Update Cargo.tomls for substrate packages
* Tendermint SelectChain
This is incompatible with Substrate's expectations, yet should be valid
for ours
* Move the node over to the new SelectChain
* Minor tweaks
* Update SelectChain documentation
* Remove substrate/node lib.rs
This shouldn't be used as a library AFAIK. While runtime should be, and
arguably should even be published, I have yet to see node in the same
way. Helps tighten API boundaries.
* Remove unused macro_use
* Replace panicking todos with stubs and // TODO
Enables progress.
* Reduce chain_spec and use more accurate naming
* Implement block proposal logic
* Modularize to get_proposal
* Trigger block importing
Doesn't wait for the response yet, which it needs to.
* Get the result of block importing
* Split import_queue into a series of files
* Provide a way to create the machine
The BasicQueue returned obscures the TendermintImport struct.
Accordingly, a Future scoped with access is returned upwards, which when
awaited will create the machine. This makes creating the machine
optional while maintaining scope boundaries.
Is sufficient to create a 1-node net which produces and finalizes
blocks.
* Don't import justifications multiple times
Also don't broadcast blocks which were solely proposed.
* Correct justication import pipeline
Removes JustificationImport as it should never be used.
* Announce blocks
By claiming File, they're not sent ovber the P2P network before they
have a justification, as desired. Unfortunately, they never were. This
works around that.
* Add an assert to verify proposed children aren't best
* Consolidate C and I generics into a TendermintClient trait alias
* Expand sanity checks
Substrate doesn't expect nor officially support children with less work
than their parents. It's a trick used here. Accordingly, ensure the
trick's validity.
* When resetting, use the end time of the round which was committed to
The machine reset to the end time of the current round. For a delayed
network connection, a machine may move ahead in rounds and only later
realize a prior round succeeded. Despite acknowledging that round's
success, it would maintain its delay when moving to the next block,
bricking it.
Done by tracking the end time for each round as they occur.
* Move Commit from including the round to including the round's end_time
The round was usable to build the current clock in an accumulated
fashion, relative to the previous round. The end time is the absolute
metric of it, which can be used to calculate the round number (with all
previous end times).
Substrate now builds off the best block, not genesis, using the end time
included in the justification to start its machine in a synchronized
state.
Knowing the end time of a round, or the round in which block was
committed to, is necessary for nodes to sync up with Tendermint.
Encoding it in the commit ensures it's long lasting and makes it readily
available, without the load of an entire transaction.
* Add a TODO on Tendermint
* Misc bug fixes
* More misc bug fixes
* Clean up lock acquisition
* Merge weights and signing scheme into validators, documenting needed changes
* Add pallet sessions to runtime, create pallet-tendermint
* Update node to use pallet sessions
* Update support URL
* Partial work on correcting pallet calls
* Redo Tendermint folder structure
* TendermintApi, compilation fixes
* Fix the stub round robin
At some point, the modulus was removed causing it to exceed the
validators list and stop proposing.
* Use the validators list from the session pallet
* Basic Gossip Validator
* Correct Substrate Tendermint start block
The Tendermint machine uses the passed in number as the block's being
worked on number. Substrate passed in the already finalized block's
number.
Also updates misc comments.
* Clean generics in Tendermint with a monolith with associated types
* Remove the Future triggering the machine for an async fn
Enables passing data in, such as the network.
* Move TendermintMachine from start_num, time to last_num, time
Provides an explicitly clear API clearer to program around.
Also adds additional time code to handle an edge case.
* Connect the Tendermint machine to a GossipEngine
* Connect broadcast
* Remove machine from TendermintImport
It's not used there at all.
* Merge Verifier into block_import.rs
These two files were largely the same, just hooking into sync structs
with almost identical imports. As this project shapes up, removing dead
weight is appreciated.
* Create a dedicated file for being a Tendermint authority
* Deleted comment code related to PoW
* Move serai_runtime specific code from tendermint/client to node
Renames serai-consensus to sc_tendermint
* Consolidate file structure in sc_tendermint
* Replace best_* with finalized_*
We test their equivalency yet still better to use finalized_* in
general.
* Consolidate references to sr25519 in sc_tendermint
* Add documentation to public structs/functions in sc_tendermint
* Add another missing comment
* Make sign asynchronous
Some relation to https://github.com/serai-dex/serai/issues/95.
* Move sc_tendermint to async sign
* Implement proper checking of inherents
* Take in a Keystore and validator ID
* Remove unnecessary PhantomDatas
* Update node to latest sc_tendermint
* Configure node for a multi-node testnet
* Fix handling of the GossipEngine
* Use a rounded genesis to obtain sufficient synchrony within the Docker env
* Correct Serai d-f names in Docker
* Remove an attempt at caching I don't believe would ever hit
* Add an already in chain check to block import
While the inner should do this for us, we call verify_order on our end
*before* inner to ensure sequential import. Accordingly, we need to
provide our own check.
Removes errors of "non-sequential import" when trying to re-import an
existing block.
* Update the consensus documentation
It was incredibly out of date.
* Add a _ to the validator arg in slash
* Make the dev profile a local testnet profile
Restores a dev profile which only has one validator, locally running.
* Reduce Arcs in TendermintMachine, split Signer from SignatureScheme
* Update sc_tendermint per previous commit
* Restore cache
* Remove error case which shouldn't be an error
* Stop returning errors on already existing blocks entirely
* Correct Dave, Eve, and Ferdie to not run as validators
* Rename dev to devnet
--dev still works thanks to the |. Acheieves a personal preference of
mine with some historical meaning.
* Add message expiry to the Tendermint gossip
* Localize the LibP2P protocol to the blockchain
Follows convention by doing so. Theoretically enables running multiple
blockchains over a single LibP2P connection.
* Add a version to sp-runtime in tendermint-machine
* Add missing trait
* Bump Substrate dependency
Fixes#147.
* Implement Schnorr half-aggregation from https://eprint.iacr.org/2021/350.pdf
Relevant to https://github.com/serai-dex/serai/issues/99.
* cargo update (tendermint)
* Move from polling loops to a pure IO model for sc_tendermint's gossip
* Correct protocol name handling
* Use futures mpsc instead of tokio
* Timeout futures
* Move from a yielding loop to select in tendermint-machine
* Update Substrate to the new TendermintHandle
* Use futures pin instead of tokio
* Only recheck blocks with non-fatal inherent transaction errors
* Update to the latest substrate
* Separate the block processing time from the latency
* Add notes to the runtime
* Don't spam slash
Also adds a slash condition of failing to propose.
* Support running TendermintMachine when not a validator
This supports validators who leave the current set, without crashing
their nodes, along with nodes trying to become validators (who will now
seamlessly transition in).
* Properly define and pass around the block size
* Correct the Duration timing
The proposer will build it, send it, then process it (on the first
round). Accordingly, it's / 3, not / 2, as / 2 only accounted for the
latter events.
* Correct time-adjustment code on round skip
* Have the machine respond to advances made by an external sync loop
* Clean up time code in tendermint-machine
* BlockData and RoundData structs
* Rename Round to RoundNumber
* Move BlockData to a new file
* Move Round to an Option due to the pseudo-uninitialized state we create
Before the addition of RoundData, we always created the round, and on
.round(0), simply created it again. With RoundData, and the changes to
the time code, we used round 0, time 0, the latter being incorrect yet
not an issue due to lack of misuse.
Now, if we do misuse it, it'll panic.
* Clear the Queue instead of draining and filtering
There shouldn't ever be a message which passes the filter under the
current design.
* BlockData::new
* Move more code into block.rs
Introduces type-aliases to obtain Data/Message/SignedMessage solely from
a Network object.
Fixes a bug regarding stepping when you're not an active validator.
* Have verify_precommit_signature return if it verified the signature
Also fixes a bug where invalid precommit signatures were left standing
and therefore contributing to commits.
* Remove the precommit signature hash
It cached signatures per-block. Precommit signatures are bound to each
round. This would lead to forming invalid commits when a commit should
be formed. Under debug, the machine would catch that and panic. On
release, it'd have everyone who wasn't a validator fail to continue
syncing.
* Slight doc changes
Also flattens the message handling function by replacing an if
containing all following code in the function with an early return for
the else case.
* Always produce notifications for finalized blocks via origin overrides
* Correct weird formatting
* Update to the latest tendermint-machine
* Manually step the Tendermint machine when we synced a block over the network
* Ignore finality notifications for old blocks
* Remove a TODO resolved in 8c51bc011d
* Add a TODO comment to slash
Enables searching for the case-sensitive phrase and finding it.
* cargo fmt
* Use a tmp DB for Serai in Docker
* Remove panic on slash
As we move towards protonet, this can happen (if a node goes offline),
yet it happening brings down the entire net right now.
* Add log::error on slash
* created shared volume between containers
* Complete the sh scripts
* Pass in the genesis time to Substrate
* Correct block announcements
They were announced, yet not marked best.
* Correct pupulate_end_time
It was used as inclusive yet didn't work inclusively.
* Correct gossip channel jumping when a block is synced via Substrate
* Use a looser check in import_future
This triggered so it needs to be accordingly relaxed.
* Correct race conditions between add_block and step
Also corrects a <= to <.
* Update cargo deny
* rename genesis-service to genesis
* Update Cargo.lock
* Correct runtime Cargo.toml whitespace
* Correct typo
* Document recheck
* Misc lints
* Fix prev commit
* Resolve low-hanging review comments
* Mark genesis/entry-dev.sh as executable
* Prevent a commit from including the same signature multiple times
Yanks tendermint-machine 0.1.0 accordingly.
* Update to latest nightly clippy
* Improve documentation
* Use clearer variable names
* Add log statements
* Pair more log statements
* Clean TendermintAuthority::authority as possible
Merges it into new. It has way too many arguments, yet there's no clear path at
consolidation there, unfortunately.
Additionally provides better scoping within itself.
* Fix#158
Doesn't use lock_import_and_run for reasons commented (lack of async).
* Rename guard to lock
* Have the devnet use the current time as the genesis
Possible since it's only a single node, not requiring synchronization.
* Fix gossiping
I really don't know what side effect this avoids and I can't say I care at this
point.
* Misc lints
