* Remove mining from the bitcoin/monero docker files
The tests should control block production in order to test various
circumstances. The automatic mining disrupts assumptions made in testing. Since
we're now using the Bitcoin docker container for testing...
* Multiple fixes to the Bitcoin processor
Doesn't unwrap on RPC errors. Returns the expected connection error.
Fee calculation has a random - 1. This has been removed.
Supports the change address being an Option, as it is. This should not have
been blindly unwrapped.
* Remove unnecessary RPC code
* Further RPC simplifications
* Simplify Bitcoin action
It should not be mining.
* cargo fmt
* Finish RPC simplifications
* Run bitcoind as a daemon
* Remove the requirement on txindex
Saves tens of GB.
Also has attempt_send no longer return a list of outputs. That's incompatible
with this and only relevant to old scheduling designs.
* Remove number from Bitcoin SignableTransaction
Monero requires the current block number for decoy selection. Bitcoin doesn't
have a use.
* Ban coinbase transactions
These are burdened by maturity, so it's critically flawed to support them.
This causes the test_send function to fail as its working was premised on
a coinbase output. While it does make an actual output, it had insufficient
funds for the test's expectations due to regtest halving every 150 blocks.
In order to workaround this, the test will invalidate any existing chain,
offering a fresh start.
Also removes test_get_spendables and simplifies test_send.
* Various simplifications
Modifies SpendableOutput further to not require RPC calls at time of sign.
Removes the need to have get_transaction in the RPC.
* Clean prepare_send
* Update the Bitcoin TransactionMachine to output a Transaction
* Bitcoin TransactionMachine simplifications

* 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.

* 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.
* Remove the explicit included participants from FROST
Now, whoever submits preprocesses becomes the signing set. Better separates
preprocess from sign, at the cost of slightly more annoying integrations
(Monero needs to now independently lagrange/offset its key images).
* Support caching preprocesses
Closes https://github.com/serai-dex/serai/issues/40.
I *could* have added a serialization trait to Algorithm and written a ton of
data to disk, while requiring Algorithm implementors also accept such work.
Instead, I moved preprocess to a seeded RNG (Chacha20) which should be as
secure as the regular RNG. Rebuilding from cache simply loads the previously
used Chacha seed, making the Algorithm oblivious to the fact it's being
rebuilt from a cache. This removes any requirements for it to be modified
while guaranteeing equivalency.
This builds on the last commit which delayed determining the signing set till
post-preprocess acquisition. Unfortunately, that commit did force preprocess
from ThresholdView to ThresholdKeys which had visible effects on Monero.
Serai will actually need delayed set determination for #163, and overall,
it remains better, hence it's inclusion.
* Document FROST preprocess caching
* Update ethereum to new FROST
* Fix bug in Monero offset calculation and update processor
* Create message types for FROST key gen
Taking in reader borrows absolutely wasn't feasible. Now, proper types
which can be read (and then passed directly, without a mutable borrow)
exist for key_gen. sign coming next.
* Move FROST signing to messages, not Readers/Writers/Vec<u8>
Also takes the nonce handling code and makes a dedicated file for it,
aiming to resolve complex types and make the code more legible by
replacing its previously inlined state.
* clippy
* Update FROST tests
* read_signature_share
* Update the Monero library to the new FROST packages
* Update processor to latest FROST
* Tweaks to terminology and documentation
Unbeknowst to me, height doesn't have a universal definition of the
chain length.
Bitcoin defines height as the block number, with getblockcount existing
for the chain length.
Ethereum uses the unambiguous term "block number".
Monero defines height as both the block number and the chain length.
Instead of arguing about who's right, it's agreed it referring to both
isn't productive. While we could provide our own definition, taking a
side, moving to the unambiguous block number prevents future hiccups.
height is now only a term in the Monero code, where it takes its
Monero-specific definition, as documented in the processor.
* Apply Zeroize to nonces used in Bulletproofs
Also makes bit decomposition constant time for a given amount of
outputs.
* Fix nonce reuse for single-signer CLSAG
* Attach Zeroize to most structures in Monero, and ZOnDrop to anything with private data
* Zeroize private keys and nonces
* Merge prepare_outputs and prepare_transactions
* Ensure CLSAG is constant time
* Pass by borrow where needed, bug fixes
The past few commitments have been one in-progress chunk which I've
broken up as best read.
* Add Zeroize to FROST structs
Still needs to zeroize internally, yet next step. Not quite as
aggressive as Monero, partially due to the limitations of HashMaps,
partially due to less concern about metadata, yet does still delete a
few smaller items of metadata (group key, context string...).
* Remove Zeroize from most Monero multisig structs
These structs largely didn't have private data, just fields with private
data, yet those fields implemented ZeroizeOnDrop making them already
covered. While there is still traces of the transaction left in RAM,
fully purging that was never the intent.
* Use Zeroize within dleq
bitvec doesn't offer Zeroize, so a manual zeroing has been implemented.
* Use Zeroize for random_nonce
It isn't perfect, due to the inability to zeroize the digest, and due to
kp256 requiring a few transformations. It does the best it can though.
Does move the per-curve random_nonce to a provided one, which is allowed
as of https://github.com/cfrg/draft-irtf-cfrg-frost/pull/231.
* Use Zeroize on FROST keygen/signing
* Zeroize constant time multiexp.
* Correct when FROST keygen zeroizes
* Move the FROST keys Arc into FrostKeys
Reduces amount of instances in memory.
* Manually implement Debug for FrostCore to not leak the secret share
* Misc bug fixes
* clippy + multiexp test bug fixes
* Correct FROST key gen share summation
It leaked our own share for ourself.
* Fix cross-group DLEq tests
Considering they take 7 seconds to generate, thanks to #68, the ability
to generate them at the start instead of on first BP is greatly
appreciated.
Also performs minor cleanups regarding BPs.
Modifies FROST behavior so group_key has the offset applied regardless
of if view was called. The unaltered secret_share and
verification_shares (as they have differing values depending on the
signing set) are no longer publicly accessible.
