The Processor's coins folder referred to the networks it could process, as did
its Coin trait. This, and other similar cases throughout the codebase, have now
been corrected.
Also corrects dated documentation for a key pair is confirmed under the
validator-sets pallet.
This is a horrible impl which does a full ser of everything on every change.
It's just the minimal changes to resolve this TODO and able testnet deployment.
Due to the ordered message-queue, there's no benefit to multiple emissions as
there's no risk a completion will be missed. If it has yet to be read, sending
another which only be read after isn't helpful.
Simplifies code a decent bit.
This is technically over-agressive, as a dropped output will reduce the fee,
yet this edge case is so minor the flow for it to not be over-aggressive (over
a few fractions of a cent) is by no means worth it.
Fixes the crash causable by the WIP send_test.
It waited for CONFIRMATIONS + 1 confirmations, instead of CONFIRMATIONS
confirmations.
Also adds a lib interface to access the coin traits and its constants.
* add mlsag
* fix last commit
* fix miner v1 txs
* fix non-miner v1 txs
* add borromean + fix mlsag
* add block hash calculations
* fix for the jokester that added unreduced scalars
to the borromean signature of
2368d846e671bf79a1f84c6d3af9f0bfe296f043f50cf17ae5e485384a53707b
* Add Borromean range proof verifying functionality
* Add MLSAG verifying functionality
* fmt & clippy :)
* update MLSAG, ss2_elements will always be 2
* Add MgSig proving
* Tidy block.rs
* Tidy Borromean, fix bugs in last commit, replace todo! with unreachable!
* Mark legacy EcdhInfo amount decryption as experimental
* Correct comments
* Write a new impl of the merkle algorithm
This one tries to be understandable.
* Only pull in things only needed for experimental when experimental
* Stop caching the Monero block hash now in processor that we have Block::hash
* Corrections for recent processor commit
* Use a clearer algorithm for the merkle
Should also be more efficient due to not shifting as often.
* Tidy Mlsag
* Remove verify_rct_* from Mlsag
Both methods were ports from Monero, overtly specific without clear
documentation. They need to be added back in, with documentation, or included
in a node which provides the necessary further context for them to be naturally
understandable.
* Move mlsag/mod.rs to mlsag.rs
This should only be a folder if it has multiple files.
* Replace EcdhInfo terminology
The ECDH encrypted the amount, yet this struct contained the encrypted amount,
not some ECDH.
Also corrects the types on the original EcdhInfo struct.
* Correct handling of commitment masks when scanning
* Route read_array through read_raw_vec
* Misc lint
* Make a proper RctType enum
No longer caches RctType in the RctSignatures as well.
* Replace Vec<Bulletproofs> with Bulletproofs
Monero uses aggregated range proofs, so there's only ever one Bulletproof. This
is enforced with a consensus rule as well, making this safe.
As for why Monero uses a vec, it's probably due to the lack of variadic typing
used. Its effectively an Option for them, yet we don't need an Option since we
do have variadic typing (enums).
* Add necessary checks to Eventuality re: supported protocols
* Fix for block 202612 and fix merkel root calculations
* MLSAG (de)serialisation fix
ss_2_elements will not always be 2 as rct type 1 transactions are not enforced to have one input
* Revert "MLSAG (de)serialisation fix"
This reverts commit 5e710e0c96.
here it checks number of MGs == number of inputs:
0a1eaf26f9/src/cryptonote_core/tx_verification_utils.cpp (L60-59)
and here it checks for RctTypeFull number of MGs == 1:
0a1eaf26f9/src/ringct/rctSigs.cpp (L1325)
so number of inputs == 1
so ss_2_elements == 2
* update `MlsagAggregate` comment
* cargo update
Resolves a yanked crate
* Move location of serai-client in Cargo.toml

Provides a DST, and associated metadata as beneficial.
Also utilizes MuSig's context to session-bind. Since set_keys_messages also
binds to set, this is semi-redundant, yet that's appreciated.
When we receive messages, we're provided with a message ID we can use to
prevent handling an item multiple times. That doesn't prevent us from *sending*
an item multiple times though. Thanks to the UID system, we can now not send if
already present.
Alternatively, we can remove the ordered message ID for just the UID, allowing
duplicates to be sent without issue, and handled on the receiving end.
When a Substrate block occurs, the coordinator is expected to emit
SubstrateBlock. This causes the processor to begin a variety of plans. The
processor now emits SubstrateBlockAck, explicitly listing all plan IDs, before
starting signing.
This lets the coordinator provide a SubstrateBlock transaction, and with it,
recognize all plan IDs as valid.
Prior, we would've had to have a spotty algorithm based upon the upcoming
Preprocess messages, or if we immediately provided the SubstrateBlock
transaction, then wait for the processor to inform us of the contained plans.
This creates an explicitly proper async flow not reliant on waiting for data
availability.
Alternatively, we could've replaced Preprocess with (Block, Vec<Preprocess>).
This would've been more efficient, yet also clunky due to the multiple usages
of the Preprocess message.
There is the ability to cause state bloat by flooding Tributary.
KeyGen/Sign specifically shouldn't allow bloat since we check the
commitments/preprocesses/shares for validity. Accordingly, any invalid data
(such as bloat) should be detected.
It was posssible to place bloat after the valid data. Doing so would be
considered a valid KeyGen/Sign message, yet could add up to 50k kB per sign.
[0; 32] is a magic for no block has been set yet due to this being the first
key pair. If [0; 32] is the latest finalized block, the processor determines
an activation block based on timestamps.
This doesn't use an Option for ergonomic reasons.
It originally wasn't an enum so software which had yet to update before an
integration wouldn't error (as now enums are strictly typed). The strict typing
is preferable though.
SubstrateBlock's provision of the most recently acknowledged block has
equivalent information with the same latency. Accordingly, there's no need for
it.
