One Round DKG (#589) * 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.

Tokens pallet (#243) * 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

Removes use of UncheckedExtrinsic as a pointlessly (for us) length-prefixed block with a more complicated signing algorithm than advantageous. In the future, we should considering consolidating the various primitives crates. I'm not convinced we benefit from one primitives crate per pallet.

Cache the block's events within TemporalSerai Event retrieval was prior: - Retrieve all events in the block, which may be hundreds of KB - Filter to just a few Since it's frequent to want multiple sets of events, each filtered in their own way, this caused the retrieval to happen multiple times. Now, it only will happen once. Also has the scoped clients take a reference, not an owned TemporalSerai.

Processor (#259) * 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

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

Coordinator Cleanup (#481) * Move logic for evaluating if a cosign should occur to its own file Cleans it up and makes it more robust. * Have expected_next_batch return an error instead of retrying While convenient to offer an error-free implementation, it potentially caused very long lived lock acquisitions in handle_processor_message. * Unify and clean DkgConfirmer and DkgRemoval Does so via adding a new file for the common code, SigningProtocol. Modifies from_cache to return the preprocess with the machine, as there's no reason not to. Also removes an unused Result around the type. Clarifies the security around deterministic nonces, removing them for saved-to-disk cached preprocesses. The cached preprocesses are encrypted as the DB is not a proper secret store. Moves arguments always present in the protocol from function arguments into the struct itself. Removes the horribly ugly code in DkgRemoval, fixing multiple issues present with it which would cause it to fail on use. * Set SeraiBlockNumber in cosign.rs as it's used by the cosigning protocol * Remove unnecessary Clone from lambdas in coordinator * Remove the EventDb from Tributary scanner We used per-Transaction DB TXNs so on error, we don't have to rescan the entire block yet only the rest of it. We prevented scanning multiple transactions by tracking which we already had. This is over-engineered and not worth it. * Implement borsh for HasEvents, removing the manual encoding * Merge DkgConfirmer and DkgRemoval into signing_protocol.rs Fixes a bug in DkgConfirmer which would cause it to improperly handle indexes if any validator had multiple key shares. * Strictly type DataSpecification's Label * Correct threshold_i_map_to_keys_and_musig_i_map It didn't include the participant's own index and accordingly was offset. * Create TributaryBlockHandler This struct contains all variables prior passed to handle_block and stops them from being passed around again and again. This also ensures fatal_slash is only called while handling a block, as needed as it expects to operate under perfect consensus. * Inline accumulate, store confirmation nonces with shares Inlining accumulate makes sense due to the amount of data accumulate needed to be passed. Storing confirmation nonces with shares ensures that both are available or neither. Prior, one could be yet the other may not have been (requiring an assert in runtime to ensure we didn't bungle it somehow). * Create helper functions for handling DkgRemoval/SubstrateSign/Sign Tributary TXs * Move Label into SignData All of our transactions which use SignData end up with the same common usage pattern for Label, justifying this. Removes 3 transactions, explicitly de-duplicating their handlers. * Remove CurrentlyCompletingKeyPair for the non-contextual DkgKeyPair * Remove the manual read/write for TributarySpec for borsh This struct doesn't have any optimizations booned by the manual impl. Using borsh reduces our scope. * Use temporary variables to further minimize LoC in tributary handler * Remove usage of tuples for non-trivial Tributary transactions * Remove serde from dkg serde could be used to deserialize intenrally inconsistent objects which could lead to panics or faults. The BorshDeserialize derives have been replaced with a manual implementation which won't produce inconsistent objects. * Abstract Future generics using new trait definitions in coordinator * Move published_signed_transaction to tributary/mod.rs to reduce the size of main.rs * Split coordinator/src/tributary/mod.rs into spec.rs and transaction.rs

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

Replace "coin" with "network" 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.

Processor (#259) * 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.
