ff 0.13 (#269)
* 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 |

Remove Tendermint for GRANDPA
Updates to polkadot-v0.9.40, with a variety of dependency updates accordingly. Substrate thankfully now uses k256 0.13, pathing the way for #256. We couldn't upgrade to polkadot-v0.9.40 without this due to polkadot-v0.9.40 having fundamental changes to syncing. While we could've updated tendermint, it's not worth the continued development effort given its inability to work with multiple validator sets. Purges sc-tendermint. Keeps tendermint-machine for #163. Closes #137, #148, #157, #171. #96 and #99 should be re-scoped/clarified. #134 and #159 also should be clarified. #169 is also no longer a priority since we're only considering temporal deployments of tendermint. #170 also isn't since we're looking at effectively sharded validator sets, so there should be no singular large set needing high performance. |

Move in instructions from inherent transactions to unsigned transactions
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. |

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 |

The automatic mining disrupts assumptions made in testing. Since we're now using the Bitcoin docker container for testing... * Multiple fixes to the Bitcoin processor Doesn't unwrap on RPC errors. Returns the expected connection error. Fee calculation has a random - 1. This has been removed. Supports the change address being an Option, as it is. This should not have been blindly unwrapped. * Remove unnecessary RPC code * Further RPC simplifications * Simplify Bitcoin action It should not be mining. * cargo fmt * Finish RPC simplifications * Run bitcoind as a daemon * Remove the requirement on txindex Saves tens of GB. Also has attempt_send no longer return a list of outputs. That's incompatible with this and only relevant to old scheduling designs. * Remove number from Bitcoin SignableTransaction Monero requires the current block number for decoy selection. Bitcoin doesn't have a use. * Ban coinbase transactions These are burdened by maturity, so it's critically flawed to support them. This causes the test_send function to fail as its working was premised on a coinbase output. While it does make an actual output, it had insufficient funds for the test's expectations due to regtest halving every 150 blocks. In order to workaround this, the test will invalidate any existing chain, offering a fresh start. Also removes test_get_spendables and simplifies test_send. * Various simplifications Modifies SpendableOutput further to not require RPC calls at time of sign. Removes the need to have get_transaction in the RPC. * Clean prepare_send * Update the Bitcoin TransactionMachine to output a Transaction * Bitcoin TransactionMachine simplifications * Update XOnly key handling * Use a single sighash cache * Move tweak_keys * Remove unnecessary PSBT sets * Restore removed newlines * Other newlines * Replace calculate_weight's custom math with a dummy TX serialize * Move BTC TX construction code from processor to bitcoin * Rename transactions.rs to wallet.rs * Remove unused crate * Note TODO * Clean bitcoin signature test * Make unit test out of BTC FROST signing test * Final lint * Remove usage of PartiallySignedTransaction --------- Co-authored-by: Luke Parker <lukeparker5132@gmail.com> |

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 |

Initial In Instructions pallet and Serai client lib (#233)
* Initial work on an In Inherents pallet * Add an event for when a batch is executed * Add a dummy provider for InInstructions * Add in-instructions to the node * Add the Serai runtime API to the processor * Move processor tests around * Build a subxt Client around Serai * Successfully get Batch events from Serai Renamed processor/substrate to processor/serai. * Much more robust InInstruction pallet * Implement the workaround from https://github.com/paritytech/subxt/issues/602 * Initial prototype of processor generated InInstructions * Correct PendingCoins data flow for InInstructions * Minor lint to in-instructions * Remove the global Serai connection for a partial re-impl * Correct ID handling of the processor test * Workaround the delay in the subscription * Make an unwrap an if let Some, remove old comments * Lint the processor toml * Rebase and update * Move substrate/in-instructions to substrate/in-instructions/pallet * Start an in-instructions primitives lib * Properly update processor to subxt 0.24 Also corrects failures from the rebase. * in-instructions cargo update * Implement IsFatalError * is_inherent -> true * Rename in-instructions crates and misc cleanup * Update documentation * cargo update * Misc update fixes * Replace height with block_number * Update processor src to latest subxt * Correct pipeline for InInstructions testing * Remove runtime::AccountId for serai_primitives::NativeAddress * Rewrite the in-instructions pallet Complete with respect to the currently written docs. Drops the custom serializer for just using SCALE. Makes slight tweaks as relevant. * Move instructions' InherentDataProvider to a client crate * Correct doc gen * Add serde to in-instructions-primitives * Add in-instructions-primitives to pallet * Heights -> BlockNumbers * Get batch pub test loop working * Update in instructions pallet terminology Removes the ambiguous Coin for Update. Removes pending/artificial latency for furture client work. Also moves to using serai_primitives::Coin. * Add a BlockNumber primitive * Belated cargo fmt * Further document why DifferentBatch isn't fatal * Correct processor sleeps * Remove metadata at compile time, add test framework for Serai nodes * Remove manual RPC client * Simplify update test * Improve re-exporting behavior of serai-runtime 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 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 |

* 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
