By default, tokio-spawned worker panics will only kill the task, not the
program. Due to our extensive use of panicking on invariants, we should ensure
the program exits.
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.
This is a horrible impl which does a full ser of everything on every change.
It's just the minimal changes to resolve this TODO and able testnet deployment.
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.
This is technically over-agressive, as a dropped output will reduce the fee,
yet this edge case is so minor the flow for it to not be over-aggressive (over
a few fractions of a cent) is by no means worth it.
Fixes the crash causable by the WIP send_test.
It waited for CONFIRMATIONS + 1 confirmations, instead of CONFIRMATIONS
confirmations.
Also adds a lib interface to access the coin traits and its constants.
All uses were safe due to addresses being converted to script_pubkeys which
don't embed their network. The only risk of there being an issue is if a
future address spec did embed the net ID into the script_pubkey and that was
moved to.
This resolves the audit note and does offer that tightening.
* add mlsag
* fix last commit
* fix miner v1 txs
* fix non-miner v1 txs
* add borromean + fix mlsag
* add block hash calculations
* fix for the jokester that added unreduced scalars
to the borromean signature of
2368d846e671bf79a1f84c6d3af9f0bfe296f043f50cf17ae5e485384a53707b
* Add Borromean range proof verifying functionality
* Add MLSAG verifying functionality
* fmt & clippy :)
* update MLSAG, ss2_elements will always be 2
* Add MgSig proving
* Tidy block.rs
* Tidy Borromean, fix bugs in last commit, replace todo! with unreachable!
* Mark legacy EcdhInfo amount decryption as experimental
* Correct comments
* Write a new impl of the merkle algorithm
This one tries to be understandable.
* Only pull in things only needed for experimental when experimental
* Stop caching the Monero block hash now in processor that we have Block::hash
* Corrections for recent processor commit
* Use a clearer algorithm for the merkle
Should also be more efficient due to not shifting as often.
* Tidy Mlsag
* Remove verify_rct_* from Mlsag
Both methods were ports from Monero, overtly specific without clear
documentation. They need to be added back in, with documentation, or included
in a node which provides the necessary further context for them to be naturally
understandable.
* Move mlsag/mod.rs to mlsag.rs
This should only be a folder if it has multiple files.
* Replace EcdhInfo terminology
The ECDH encrypted the amount, yet this struct contained the encrypted amount,
not some ECDH.
Also corrects the types on the original EcdhInfo struct.
* Correct handling of commitment masks when scanning
* Route read_array through read_raw_vec
* Misc lint
* Make a proper RctType enum
No longer caches RctType in the RctSignatures as well.
* Replace Vec<Bulletproofs> with Bulletproofs
Monero uses aggregated range proofs, so there's only ever one Bulletproof. This
is enforced with a consensus rule as well, making this safe.
As for why Monero uses a vec, it's probably due to the lack of variadic typing
used. Its effectively an Option for them, yet we don't need an Option since we
do have variadic typing (enums).
* Add necessary checks to Eventuality re: supported protocols
* Fix for block 202612 and fix merkel root calculations
* MLSAG (de)serialisation fix
ss_2_elements will not always be 2 as rct type 1 transactions are not enforced to have one input
* Revert "MLSAG (de)serialisation fix"
This reverts commit 5e710e0c96.
here it checks number of MGs == number of inputs:
0a1eaf26f9/src/cryptonote_core/tx_verification_utils.cpp (L60-59)
and here it checks for RctTypeFull number of MGs == 1:
0a1eaf26f9/src/ringct/rctSigs.cpp (L1325)
so number of inputs == 1
so ss_2_elements == 2
* update `MlsagAggregate` comment
* cargo update
Resolves a yanked crate
* Move location of serai-client in Cargo.toml

Provides a DST, and associated metadata as beneficial.
Also utilizes MuSig's context to session-bind. Since set_keys_messages also
binds to set, this is semi-redundant, yet that's appreciated.
When we receive messages, we're provided with a message ID we can use to
prevent handling an item multiple times. That doesn't prevent us from *sending*
an item multiple times though. Thanks to the UID system, we can now not send if
already present.
Alternatively, we can remove the ordered message ID for just the UID, allowing
duplicates to be sent without issue, and handled on the receiving end.
When a Substrate block occurs, the coordinator is expected to emit
SubstrateBlock. This causes the processor to begin a variety of plans. The
processor now emits SubstrateBlockAck, explicitly listing all plan IDs, before
starting signing.
This lets the coordinator provide a SubstrateBlock transaction, and with it,
recognize all plan IDs as valid.
Prior, we would've had to have a spotty algorithm based upon the upcoming
Preprocess messages, or if we immediately provided the SubstrateBlock
transaction, then wait for the processor to inform us of the contained plans.
This creates an explicitly proper async flow not reliant on waiting for data
availability.
Alternatively, we could've replaced Preprocess with (Block, Vec<Preprocess>).
This would've been more efficient, yet also clunky due to the multiple usages
of the Preprocess message.
There is the ability to cause state bloat by flooding Tributary.
KeyGen/Sign specifically shouldn't allow bloat since we check the
commitments/preprocesses/shares for validity. Accordingly, any invalid data
(such as bloat) should be detected.
It was posssible to place bloat after the valid data. Doing so would be
considered a valid KeyGen/Sign message, yet could add up to 50k kB per sign.
[0; 32] is a magic for no block has been set yet due to this being the first
key pair. If [0; 32] is the latest finalized block, the processor determines
an activation block based on timestamps.
This doesn't use an Option for ergonomic reasons.
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.
SubstrateBlock's provision of the most recently acknowledged block has
equivalent information with the same latency. Accordingly, there's no need for
it.
Clearly establishes why consistency is guaranteed from a Rust borrow-checker
mindset. While there are plenty of... 'violations', they're clearly explained.
Hopefully, this method of thinking helps promote/ensure consistency in the
future.
The signing set should be the first group to submit preprocesses to Tributary.
Re-attempts shouldn't be once every 30s, yet n blocks since the last relevant
message.
Removes the use of an async task/channel in the signer (and Substrate signer).
Also removes the need to be able to get the time from a coin's block, which was
a fragile system marked with a TODO already.
While Bitcoin practically doesn't have long re-orgs, it is possible for a
single miner to build a long chain. Recently, a miner found 5 blocks in a row,
which would be enough to re-org a transaction Serai considered finalized.
* 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
Moves the processor to it. This ends up as a net-neutral LoC change to the
processor, unfortunately, yet this makes bitcoin-serai safer/easier to use, and
increases the processor's usage of bitcoin-serai.
Also re-organizes bitcoin-serai a bit.
I'm really unhappy with a cfg(test) within the codebase. The double checking of
it makes it tolerable though, especially when compared to dropping these tests.
* 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.

* 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

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.

It only tested publishing updates and their successful acceptance.
Not only did we already have multiple booleans in it, yet it theoretically
could expand in the future. Not only is this more explicit, it actually cleans
some existing code.

Remove Scanner::address
It either needed to return an Option, panic on misconfiguration, or return a
distinct Scanner type based on burning bug immunity to offer this API properly.
Panicking wouldn't be proper, and the Option<Address> would've been... awkward.
The new register_subaddress function, maintaining the needed functionality,
also provides further clarity on the intended side effect of the previously
present Scanner::address function.

Initial validator sets pallet (#187)
* 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

* 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
A type alias of MoneroAddress is provided to abstract away the generic.
To keep the rest of the library sane, MoneroAddress is used everywhere.
If someone wants to use this library with another coin, they *should* be
able to parse a custom address and then recreate it as a Monero address.
While that's annoying to them, better them than any person using this
lib for Monero.
Closes#152.
* Add dkg crate
* Remove F_len and G_len
They're generally no longer used.
* Replace hash_to_vec with a provided method around associated type H: Digest
Part of trying to minimize this trait so it can be moved elsewhere. Vec,
which isn't std, may have been a blocker.
* Encrypt secret shares within the FROST library
Reduces requirements on callers in order to be correct.
* Update usage of Zeroize within FROST
* Inline functions in key_gen
There was no reason to have them separated as they were. sign probably
has the same statement available, yet that isn't the focus right now.
* Add a ciphersuite package which provides hash_to_F
* Set the Ciphersuite version to something valid
* Have ed448 export Scalar/FieldElement/Point at the top level
* Move FROST over to Ciphersuite
* Correct usage of ff in ciphersuite
* Correct documentation handling
* Move Schnorr signatures to their own crate
* Remove unused feature from schnorr
* Fix Schnorr tests
* Split DKG into a separate crate
* Add serialize to Commitments and SecretShare
Helper for buf = vec![]; .write(buf).unwrap(); buf
* Move FROST over to the new dkg crate
* Update Monero lib to latest FROST
* Correct ethereum's usage of features
* Add serialize to GeneratorProof
* Add serialize helper function to FROST
* Rename AddendumSerialize to WriteAddendum
* Update processor
* Slight fix to processor
* Create message types for FROST key gen
Taking in reader borrows absolutely wasn't feasible. Now, proper types
which can be read (and then passed directly, without a mutable borrow)
exist for key_gen. sign coming next.
* Move FROST signing to messages, not Readers/Writers/Vec<u8>
Also takes the nonce handling code and makes a dedicated file for it,
aiming to resolve complex types and make the code more legible by
replacing its previously inlined state.
* clippy
* Update FROST tests
* read_signature_share
* Update the Monero library to the new FROST packages
* Update processor to latest FROST
* Tweaks to terminology and documentation
Unbeknowst to me, height doesn't have a universal definition of the
chain length.
Bitcoin defines height as the block number, with getblockcount existing
for the chain length.
Ethereum uses the unambiguous term "block number".
Monero defines height as both the block number and the chain length.
Instead of arguing about who's right, it's agreed it referring to both
isn't productive. While we could provide our own definition, taking a
side, moving to the unambiguous block number prevents future hiccups.
height is now only a term in the Monero code, where it takes its
Monero-specific definition, as documented in the processor.
Creates a new monero-generators crate so the monero crate can run the
code in question at build time.
Saves several seconds from running the tests.
Closes https://github.com/serai-dex/serai/issues/101.
* Apply Zeroize to nonces used in Bulletproofs
Also makes bit decomposition constant time for a given amount of
outputs.
* Fix nonce reuse for single-signer CLSAG
* Attach Zeroize to most structures in Monero, and ZOnDrop to anything with private data
* Zeroize private keys and nonces
* Merge prepare_outputs and prepare_transactions
* Ensure CLSAG is constant time
* Pass by borrow where needed, bug fixes
The past few commitments have been one in-progress chunk which I've
broken up as best read.
* Add Zeroize to FROST structs
Still needs to zeroize internally, yet next step. Not quite as
aggressive as Monero, partially due to the limitations of HashMaps,
partially due to less concern about metadata, yet does still delete a
few smaller items of metadata (group key, context string...).
* Remove Zeroize from most Monero multisig structs
These structs largely didn't have private data, just fields with private
data, yet those fields implemented ZeroizeOnDrop making them already
covered. While there is still traces of the transaction left in RAM,
fully purging that was never the intent.
* Use Zeroize within dleq
bitvec doesn't offer Zeroize, so a manual zeroing has been implemented.
* Use Zeroize for random_nonce
It isn't perfect, due to the inability to zeroize the digest, and due to
kp256 requiring a few transformations. It does the best it can though.
Does move the per-curve random_nonce to a provided one, which is allowed
as of https://github.com/cfrg/draft-irtf-cfrg-frost/pull/231.
* Use Zeroize on FROST keygen/signing
* Zeroize constant time multiexp.
* Correct when FROST keygen zeroizes
* Move the FROST keys Arc into FrostKeys
Reduces amount of instances in memory.
* Manually implement Debug for FrostCore to not leak the secret share
* Misc bug fixes
* clippy + multiexp test bug fixes
* Correct FROST key gen share summation
It leaked our own share for ourself.
* Fix cross-group DLEq tests
Considering they take 7 seconds to generate, thanks to #68, the ability
to generate them at the start instead of on first BP is greatly
appreciated.
Also performs minor cleanups regarding BPs.
* Initial stab at Bulletproofs+
Does move around the existing Bulletproofs code, does still work as
expected.
* Make the Clsag RCTPrunable type work with BP and BP+
* Initial set of BP+ bug fixes
* Further bug fixes
* Remove RING_LEN as a constant
* Monero v16 TX support
Doesn't implement view tags, nor going back to v14, nor the updated BP
clawback logic.
* Support v14 and v16 at the same time
Currently intended to be done with:
cargo clippy --features "recommended merlin batch serialize experimental
ed25519 ristretto p256 secp256k1 multisig" -- -A clippy::type_complexity
-A dead_code
Consensus has been nuked for an AcceptAny currently routed throough PoW
(when it doesn't have to be, doing so just took care of a few pieces of
leg work).
Updates AGPL handling.
