Moves from concatted Dockerfiles to pseudo-templated Dockerfiles via a dedicated Rust program.
Removes the unmaintained kubernetes, not because we shouldn't have/use it, but because it's unmaintained and needs to be reworked before it's present again.
Replaces the compose with the work in the new orchestrator binary which spawns everything as expected. While this arguably re-invents the wheel, it correctly manages secrets and handles the variadic Dockerfiles.
Also adds an unrelated patch for zstd and simplifies running services a bit by greater utilizing the existing infrastructure.
---
* Delete all Dockerfile fragments, add new orchestator to generate Dockerfiles
Enables greater templating.
Also delete the unmaintained kubernetes folder *for now*. This should be
restored in the future.
* Use Dockerfiles from the orchestator
* Ignore Dockerfiles in the git repo
* Remove CI job to check Dockerfiles are as expected now that they're no longer committed
* Remove old Dockerfiles from repo
* Use Debian for monero-wallet-rpc
* Remove replace_cmds for proper usage of entry-dev
Consolidates ports a bit.
Updates serai-docker-tests from "compose" to "build".
* Only write a new dockerfile if it's distinct
Preserves the updated time metadata.
* Update serai-docker-tests
* Correct the path Dockerfiles are built from
* Correct inclusion of orchestration folder in Docker builds
* Correct debug/release flagging in the cargo command
Apparently, --debug isn't an effective NOP yet an error.
* Correct path used to run the Serai node within a Dockerfile
* Correct path in Monero Dockerfile
* Attempt storing monerod in /usr/bin
* Use sudo to move into /usr/bin in CI
* Correct 18.3.0 to 18.3.1
* Escape * with quotes
* Update deny.toml, ADD orchestration in runtime Dockerfile
* Add --detach to the Monero GH CI
* Diversify dockerfiles by network
* Fixes to network-diversified orchestration
* Bitcoin and Monero testnet scripts
* Permissions and tweaks
* Flatten scripts folders
* Add missing folder specification to Monero Dockerfile
* Have monero-wallet-rpc specify the monerod login
* Have the Docker CMD specify env variables inserted at time of Dockerfile generation
They're overrideable with the global enviornment as for tests. This enables
variable generation in orchestrator and output to productionized Docker files
without creating a life-long file within the Docker container.
* Don't add Dockerfiles into Docker containers now that they have secrets
Solely add the source code for them as needed to satisfy the workspace bounds.
* Download arm64 Monero on arm64
* Ensure constant host architecture when reproducibly building the wasm
Host architecture, for some reason, can effect the generated code despite the
target architecture always being foreign to the host architecture.
* Randomly generate infrastructure keys
* Have orchestrator generate a key, be able to create/start containers
* Ensure bash is used over sh
* Clean dated docs
* Change how quoting occurs
* Standardize to sh
* Have Docker test build the dev Dockerfiles
* Only key_gen once
* cargo update
Adds a patch for zstd and reconciles the breaking nightly change which just
occurred.
* Use a dedicated network for Serai
Also fixes SERAI_HOSTNAME passed to coordinator.
* Support providing a key over the env for the Serai node
* Enable and document running daemons for tests via serai-orchestrator
Has running containers under the dev network port forward the RPC ports.
* Use volumes for bitcoin/monero
* Use bitcoin's run.sh in GH CI
* Only use the volume for testnet (not dev)
The behavior appears to match monero core. monero core isn't
throwing an exception in the linked code, it's returning
boost::none (and logging an error) which is the same functional
behavior as finding that the output does not belong to the user.
* Use only the first input ring length for all RCT input signatures.
This is what Monero does:
ac02af9286/src/ringct/rctTypes.h (L422)https://github.com/monero-project/monero/blob/master/src/cryptonote_basic/cryptonote_basic.h#L308-L309
This isn't an issue for current transactions as from hf 12 Monero requires
all inputs to have the same number of decoys but for transactions before
that Monero would reject RCT txs with differing ring lengths. Monero would
deserialize each inputs signature using the ring length of the first so the
signatures for inputs other than the first would have a different
(wrong) number of elements for that input meaning the signature is invalid.
But as we are using the ring length of each input, which arguably is the
*correct* way, we would approve of transactions with inputs differing in
ring lengths.
* Check that there is more than one ring member for MLSAG signatures.
ac02af9286/src/ringct/rctSigs.cpp (L462)
* monero: require seed lang when decoding seed
- Require the seed language when decoding a Classic|Polyseed seed string
- As per https://github.com/monero-project/monero/issues/9089 and https://github.com/tevador/polyseed/issues/11
- Fixes#478
- Implementation note: I reused the `SeedType` enum and required it as a param to `Seed::from_string` because it seemed simplest, but perhaps there is a cleaner way to require the seed lang.
- Made sure the print statements from #487 print the seed as early as possible to help debug future issues
- A future PR could support deducing which languages a seed decodes to in order to support the UX @kayabaNerve suggested in https://github.com/monero-project/monero/issues/9089:
- "Wallets can also try to abstract [language specification], by decoding with all languages, and only asking the user if/when multiple valid options show up ("Is this seed Spanish or Italian?")."
* Lint
* 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
* Make it clear not providing a change address is fingerprintable
When no change address is provided, all change is shunted to the
fee. This PR makes it clear to the caller that it is fingerprintable
when the caller does this.
* Review comments
They're a bit more binding, smaller, provided by the Rust bitcoin library,
sane, and we don't have to worry about malleability since all of our inputs are
SegWit.
* Use debug builds in our Dockerfiles to reduce CI times
Also enables only spawning the mdns service when debug in the coordinator.
* Correct underflow in processor
Prior undetected due to relase builds not having bounds checks enabled.
* Restore Serai release due to CI/RPC failures caused by compiling it in debug mode
This is *probably* worth an issue filed upstream, if it can be tracked down.
* Correct failing debug asserts in Monero
These debug asserts assumed there was a change address to take the remainder.
If there's no change address, the remainder is shunted to the fee, causing the
fee to be distinct from the estimate.
We presumably need to modify monero-serai such that change: None isn't valid,
and users must use Change::Fingerprintable(None).
* Add v1 ring sig verifying
* allow calculating signature hash for v1 txs
* add unreduced scalar type with recovery
I have added this type for borromen sigs, the ee field can be a normal
scalar as in the verify function the ee
field is checked against a reduced scalar mean for it to verify as
correct ee must be reduced
* change block major/ minor versions to u8
this matches Monero
I have also changed a couple varint functions to accept the `VarInt`
trait
* expose `serialize_hashable` on `Block`
* add back MLSAG verifying functions
I still need to revert the commit removing support for >1 input MLSAG FULL
This adds a new rct type to separate Full and simple rct
* add back support for multiple inputs for RCT FULL
* comment `non_adjacent_form` function
also added `#[allow(clippy::needless_range_loop)]` around a loop as without a re-write satisfying clippy without it will make the function worse.
* Improve Mlsag verifying API
* fix rebase errors
* revert the changes on `reserialize_chain`
plus other misc changes
* fix no-std
* Reduce the amount of rpc calls needed for `get_block_by_number`.
This function was causing me problems, every now and then a node would return a block with a different number than requested.
* change `serialize_hashable` to give the POW hashing blob.
Monero calculates the POW hash and the block hash using *slightly* different blobs :/
* make ring_signatures public and add length check when verifying.
* Misc improvements and bug fixes

ethers-solc was used for a type (now manually specified) and to call out to
solc. Since Foundry was already a documented dependency, a call to it now
handles building.
Removing this single crate removes a total of 17 crates from our dependency
tree. While these may still be around due to Foundry, they at least may not
be.
Further work to remove the requirement on Foundry for solc alone would be
appreciated.
I don't like blindly retrying in the Monero library. The amount of errors,
which weren't present with reqwest (well, the error rate was the same, yet due
to a distinct bug this code fixed), demand we do *something* though.
The trace log shows hyper is erroring with 0 bytes of the response read. My
guess is it's somehow a closed connection? A connection pool would detect this
and have created a new connection (as this does, except once finding out
there's an issue).
While we should be able to detect this with `ready()`, we do call ready and it
claims no error. We also can successfully write which makes this... a mess.
Hopefully, it either actually works as intended, yet it at least requires two
consecutive errors which should be much less frequent.
The prior system spawned a new connection per request to enable parallelism,
yet kept hitting hyper::IncompleteMessages I couldn't track down. This
attempts to resolve those by a long-lived socket.
Halves the amount of requests per-authenticated RPC call, and accordingly is
likely still better overall.
I don't believe this is resolved yet but this is still worth pushing.
reqwest was replaced with hyper and hyper-rustls within monero-serai due to
reqwest *solely* offering a connection pool API. In the process, it was
demonstrated how quickly we can achieve equivalent functionality to reqwest for
our use cases with a fraction of the code.
This adds our own reqwest alternative to the tree, applying it to both
bitcoin-serai and message-queue. By doing so, bitcoin-serai decreases its tree
by 21 packages and the processor by 18. Cargo.lock decreases by 8 dependencies,
solely adding simple-request. Notably removed is openssl-sys and openssl.
One noted decrease functionality is the requirement on the system having
installed CA certificates. While we could fallback to the rustls certificates
if the system doesn't have any, that's blocked by
https://github.com/rustls/hyper-rustls/pulls/228.
Removes bitcoin-serai's usage of sha2 for bitcoin-hashes. While sha2 is still
in play due to modular-frost (more specifically, due to ciphersuite), this
offers a bit more performance (assuming equivalency between sha2 and
bitcoin-hashes' impl) due to removing a static for a const.
Makes secp256k1 a dev dependency for bitcoin-serai. While secp256k1 is still
pulled in via bitcoin, it's hopefully slightly better to compile now and makes
usage of secp256k1 an implementation detail of bitcoin (letting it change it
freely).
Also offers slightly more efficient signing as we don't decode to a signature
just to re-encode for the transaction.
Removes a 20s sleep for a check every second, up to 20 times, for reduced test
times in the processor.
It *looks like* hyper will drop the connection once its request sender is
dropped, regardless of if the last request hasn't had its response completed.
This attempts to resolve some spurious connection errors.
If a crate has std set, it should enable std for all dependencies in order to
let them properly select which algorithms to use. Some crates fallback to
slower/worse algorithms on no-std.
Also more aggressively sets default-features = false leading to a *10%*
reduction in the amount of crates coordinator builds.
The lack of locking the connection when making an authenticated request, which
is actually two sequential requests, risked another caller making a request in
between, invalidating the state.
Now, only unauthenticated connections share a connection object.
* Design and document a multisig rotation flow
* Make Scanner::eventualities a HashMap so it's per-key
* Don't drop eventualities, always follow through on them
Technical improvements made along the way.
* Start creating an isolate object to manage multisigs, which doesn't require being a signer
Removes key from SubstrateBlock.
* Move Scanner/Scheduler under multisigs
* Move Batch construction into MultisigManager
* Clarify "should" in Multisig Rotation docs
* Add block_number to MultisigManager, as it controls the scanner
* Move sign_plans into MultisigManager
Removes ThresholdKeys from prepare_send.
* Make SubstrateMutable an alias for MultisigManager
* Rewrite Multisig Rotation
The prior scheme had an exploit possible where funds were sent to the old
multisig, then burnt on Serai to send from the new multisig, locking liquidity
for 6 hours. While a fee could be applied to stragglers, to make this attack
unprofitable, the newly described scheme avoids all this.
* Add mini
mini is a miniature version of Serai, emphasizing Serai's nature as a
collection of independent clocks. The intended use is to identify race
conditions and prove protocols are comprehensive regarding when certain clocks
tick.
This uses loom, a prior candidate for evaluating the processor/coordinator as
free of race conditions (#361).
* Use mini to prove a race condition in the current multisig rotation docs, and prove safety of alternatives
Technically, the prior commit had mini prove the race condition.
The docs currently say the activation block of the new multisig is the block
after the next Batch's. If the two next Batches had already entered the
mempool, prior to set_keys being called, the second next Batch would be
expected to contain the new key's data yet fail to as the key wasn't public
when the Batch was actually created.
The naive solution is to create a Batch, publish it, wait until it's included,
and only then scan the next block. This sets a bound of
`Batch publication time < block time`. Optimistically, we can publish a Batch
in 24s while our shortest block time is 2m. Accordingly, we should be fine with
the naive solution which doesn't take advantage of throughput. #333 may
significantly change latency however and require an algorithm whose throughput
exceeds the rate of blocks created.
In order to re-introduce parallelization, enabling throughput, we need to
define a safe range of blocks to scan without Serai ordering the first one.
mini demonstrates safety of scanning n blocks Serai hasn't acknowledged, so
long as the first is scanned before block n+1 is (shifting the n-block window).
The docs will be updated next, to reflect this.
* Fix Multisig Rotation
I believe this is finally good enough to be final.
1) Fixes the race condition present in the prior document, as demonstrated by
mini.
`Batch`s for block `n` and `n+1`, may have been in the mempool when a
multisig's activation block was set to `n`. This would cause a potentially
distinct `Batch` for `n+1`, despite `n+1` already having a signed `Batch`.
2) Tightens when UIs should use the new multisig to prevent eclipse attacks,
and protection against `Batch` publication delays.
3) Removes liquidity fragmentation by tightening flow/handling of latency.
4) Several clarifications and documentation of reasoning.
5) Correction of "prior multisig" to "all prior multisigs" regarding historical
verification, with explanation why.
* Clarify terminology in mini
Synchronizes it from my original thoughts on potential schema to the design
actually created.
* Remove most of processor's README for a reference to docs/processor
This does drop some misc commentary, though none too beneficial. The section on
scanning, deemed sufficiently beneficial, has been moved to a document and
expanded on.
* Update scanner TODOs in line with new docs
* Correct documentation on Bitcoin::Block::time, and Block::time
* Make the scanner in MultisigManager no longer public
* Always send ConfirmKeyPair, regardless of if in-set
* Cargo.lock changes from a prior commit
* Add a policy document on defining a Canonical Chain
I accidentally committed a version of this with a few headers earlier, and this
is a proper version.
* Competent MultisigManager::new
* Update processor's comments
* Add mini to copied files
* Re-organize Scanner per multisig rotation document
* Add RUST_LOG trace targets to e2e tests
* Have the scanner wait once it gets too far ahead
Also bug fixes.
* Add activation blocks to the scanner
* Split received outputs into existing/new in MultisigManager
* Select the proper scheduler
* Schedule multisig activation as detailed in documentation
* Have the Coordinator assert if multiple `Batch`s occur within a block
While the processor used to have ack_up_to_block, enabling skips in the block
acked, support for this was removed while reworking it for multiple multisigs.
It should happen extremely infrequently.
While it would still be beneficial to have, if multiple `Batch`s could occur
within a block (with the complexity here not being worth adding that ban as a
policy), multiple `Batch`s were blocked for DoS reasons.
* Schedule payments to the proper multisig
* Correct >= to <
* Use the new multisig's key for change on schedule
* Don't report External TXs to prior multisig once deprecated
* Forward from the old multisig to the new one at all opportunities
* Move unfulfilled payments in queue from prior to new multisig
* Create MultisigsDb, splitting it out of MainDb
Drops the call to finish_signing from the Signer. While this will cause endless
re-attempts, the Signer will still consider them completed and drop them,
making this an O(n) cost at boot even if we did nothing from here.
The MultisigManager should call finish_signing once the Scanner completes the
Eventuality.
* Don't check Scanner-emitted completions, trust they are completions
Prevents needing to use async code to mark the completion and creates a
fault-free model. The current model, on fault, would cause a lack of marked
completion in the signer.
* Fix a possible panic in the processor
A shorter-chain reorg could cause this assert to trip. It's fixed by
de-duplicating the data, as the assertion checked consistency. Without the
potential for inconsistency, it's unnecessary.
* Document why an existing TODO isn't valid
* Change when we drop payments for being to the change address
The earlier timing prevents creating Plans solely to the branch address,
causing the payments to be dropped, and the TX to become an effective
aggregation TX.
* Extensively document solutions to Eventualities being potentially created after having already scanned their resolutions
* When closing, drop External/Branch outputs which don't cause progress
* Properly decide if Change outputs should be forward or not when closing
This completes all code needed to make the old multisig have a finite lifetime.
* Commentary on forwarding schemes
* Provide a 1 block window, with liquidity fragmentation risks, due to latency
On Bitcoin, this will be 10 minutes for the relevant Batch to be confirmed. On
Monero, 2 minutes. On Ethereum, ~6 minutes.
Also updates the Multisig Rotation document with the new forwarding plan.
* Implement transaction forwarding from old multisig to new multisig
Identifies a fault where Branch outputs which shouldn't be dropped may be, if
another output fulfills their next step. Locking Branch fulfillment down to
only Branch outputs is not done in this commit, but will be in the next.
* Only let Branch outputs fulfill branches
* Update TODOs
* Move the location of handling signer events to avoid a race condition
* Avoid a deadlock by using a RwLock on a single txn instead of two txns
* Move Batch ID out of the Scanner
* Increase from one block of latency on new keys activation to two
For Monero, this offered just two minutes when our latency to publish a Batch
is around a minute already. This does increase the time our liquidity can be
fragmented by up to 20 minutes (Bitcoin), yet it's a stupid attack only
possible once a week (when we rotate). Prioritizing normal users' transactions
not being subject to forwarding is more important here.
Ideally, we'd not do +2 blocks yet plus `time`, such as +10 minutes, making
this agnostic of the underlying network's block scheduling. This is a
complexity not worth it.
* Split MultisigManager::substrate_block into multiple functions
* Further tweaks to substrate_block
* Acquire a lock on all Scanner operations after calling ack_block
Gives time to call register_eventuality and initiate signing.
* Merge sign_plans into substrate_block
Also ensure the Scanner's lock isn't prematurely released.
* Use a HashMap to pass to-be-forwarded instructions, not the DB
* Successfully determine in ClosingExisting
* Move from 2 blocks of latency when rotating to 10 minutes
Superior as noted in 6d07af92ce10cfd74c17eb3400368b0150eb36d7, now trivial to
implement thanks to prior commit.
* Add note justifying measuring time in blocks when rotating
* Implement delaying of outputs received early to the new multisig per specification
* Documentation on why Branch outputs don't have the race condition concerns Change do
Also ensures 6 hours is at least N::CONFIRMATIONS, for sanity purposes.
* Remove TODO re: sanity checking Eventualities
We sanity check the Plan the Eventuality is derived from, and the Eventuality
is handled moments later (in the same file, with a clear call path). There's no
reason to add such APIs to Eventualities for a sanity check given that.
* Add TODO(now) for TODOs which must be done in this branch
Also deprecates a pair of TODOs to TODO2, and accepts the flow of the Signer
having the Eventuality.
* Correct errors in potential/future flow descriptions
* Accept having a single Plan Vec
Per the following code consuming it, there's no benefit to bifurcating it by
key.
* Only issue sign_transaction on boot for the proper signer
* Only set keys when participating in their construction
* Misc progress
Only send SubstrateBlockAck when we have a signer, as it's only used to tell
the Tributary of what Plans are being signed in response to this block.
Only immediately sets substrate_signer if session is 0.
On boot, doesn't panic if we don't have an active key (as we wouldn't if only
joining the next multisig). Continues.
* Correctly detect and set retirement block
Modifies the retirement block from first block meeting requirements to block
CONFIRMATIONS after.
Adds an ack flow to the Scanner's Confirmed event and Block event to accomplish
this, which may deadlock at this time (will be fixed shortly).
Removes an invalid await (after a point declared unsafe to use await) from
MultisigsManager::next_event.
* Remove deadlock in multisig_completed and document alternative
The alternative is simpler, albeit less efficient. There's no reason to adopt
it now, yet perhaps if it benefits modeling?
* Handle the final step of retirement, dropping the old key and setting new to existing
* Remove TODO about emitting a Block on every step
If we emit on NewAsChange, we lose the purpose of the NewAsChange period.
The only concern is if we reach ClosingExisting, and nothing has happened, then
all coins will still be in the old multisig until something finally does. This
isn't a problem worth solving, as it's latency under exceptional dead time.
* Add TODO about potentially not emitting a Block event for the reitrement block
* Restore accidentally deleted CI file
* Pair of slight tweaks
* Add missing if statement
* Disable an assertion when testing
One of the test flows currently abuses the Scanner in a way triggering it.
Eventualities need to be binding not just to a plan, yet to the execution of
the plan (the outputs). Bitcoin's Eventuality definition short-cutted this
under a honest multisig assumption, causing the following issue:
If multisig n+1 is verifying multisig n's actions, as detailed in
multi-multisig's document on multisig rotation, it'll check no outstanding
eventualities exist. If we solely bind to the plan, a malicious multisig n
could steal outbound payments yet cause the plan to be marked as successfully
completed.
By modifying the eventuality to also include the expected outputs, this is no
longer possible. Binding to the expected input is preserved in order to remain
binding to the plan (allowing two plans with the same output-set to co-exist).
Fixes where ram_scanned is updated in processor. The prior version, while safe,
would redo massive amounts of work during periods of inactivity. It also hit an
undocumented invariant where get_eventuality_completions assumes new blocks,
yet redone work wouldn't have new blocks.
Modifies Monero's generate_blocks to return the hashes of the generated blocks.
* Add in an implementation of BP+ based off the paper, intended for clarity and review
This was done as part of my work on FCMPs from Monero, and is copied from https://github.com/kayabaNerve/full-chain-membership-proofs
* Remove crate structure of BP+
* Remove arithmetic circuit code
* Remove AC/VC generators code
* Remove generator transcript
Monero uses non-transcripted static generators.
* Further trimming of generators
* Remove the single range proof
It's unused by Monero and accordingly unhelpful.
* Work on getting BP+ to compile in its new env
* Correct BP+ folder name
* Further tweaks to get closer to compiling
* Remove the ScalarMatrix file
It's only used for AC proofs
* Compiles, with tests passing
* Lock BP+ to Ed25519 instead of the generic Ciphersuite
* Resolve most warnings in BP+
* Make existing bulletproofs test easier to read
* Further strip generators
* Swap G/H as Monero did
* Replace RangeCommitment with Commitment
* Hard-code BP+ h to Ed25519's generator
* Use pub(crate) for BP+, not pub
* Replace initial_transcript with hash_plus
* Rename hash_plus to initial_transcript
* Finish integrating the FCMP BP+ impl
* Move BP+ folder
* Correct no-std support
* Rename "long_n" to eta
* Add note on non-prime order dfg points
Arguably not meaningful, as it adds the scanner yet not the RPC, and no signing
code since modular-frost doesn't support no-std yet. It's a step in the right
direction though.
Only recently (I believe the most recent HF) were output keys checked to be
valid. This means returned keys may be invalid points, despite being the
legitimate keys for the specified outputs.
Does still label the node as invalid if it doesn't return 32 bytes,
hex-encoded.
Allows running `cargo build` in monero-serai and message-queue without
erroring, since it'd automatically try to build the binaries which require
additional features.
While we could make those features not optional, it'd increase time to build
and disk space required, which is why the features exist for monero-serai and
message-queue in the first place (since both are frequently used as libs).
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.
All uses were safe due to addresses being converted to script_pubkeys which
don't embed their network. The only risk of there being an issue is if a
future address spec did embed the net ID into the script_pubkey and that was
moved to.
This resolves the audit note and does offer that tightening.
