Actually use the added `Allocations` abstraction
Start using the sessions API in the validator-sets pallet
Get a `substrate/validator-sets` approximate to compiling
Consolidates all primitives into a single crate. We didn't benefit from its
fragmentation. I'm hesitant to say the new internal-organization is better (it
may be just as clunky), but it's at least in a single crate (not spread out
over micro-crates).
The ABI is the most distinct. We now entirely own it. Block header hashes don't
directly commit to any BABE data (avoiding potentially ~4 KB headers upon
session changes), and are hashed as borsh (a more widely used codec than
SCALE). There are still Substrate variants, using SCALE and with the BABE data,
but they're prunable from a protocol design perspective.
Defines a transaction as a Vec of Calls, allowing atomic operations.
The prior workflow (now deleted) required manually specifying the packages to
check and only checked the package could compile under the stated MSRV. It
didn't verify it was actually the _minimum_ supported Rust version. The new
version finds the MSRV from scratch to check if the stated MSRV aligns.
Updates stated MSRVs accordingly.
Also removes many explicit dependencies from secq256k1 for their re-exports via
k256. Not directly relevant, just part of tidying up all the `toml`s.
It's not only helpful (to easily check where Serai's view of the external
network is) but it's necessary in case of a non-trivial chain fork to determine
which blockchain Serai considers canonical.
It makes sense for networks which support arbitrary data to do as part of their
address. This reduces the ability to perform DoSs, achieves better performance,
and better uses the type system (as now networks we don't support data on don't
have a data field).
Updates the Ethereum address definition in serai-client accordingly
* Remove subxt
Removes ~20 crates from our Cargo.lock.
Removes downloading the metadata and enables removing the getMetadata RPC route
(relevant to #379).
Moves forward #337.
Done now due to distinctions in the subxt 0.32 API surface which make it
justifiable to not update.
* fmt, update due to deny triggering on a yanked crate
* Correct the handling of substrate_block_notifier now that it's ephemeral, not long-lived
* Correct URL in tests/coordinator from ws to http
* Add SignalsConfig to chain_spec
* Correct multiexp feature flagging for rand_core std
* Remove bincode for borsh
Replaces a non-canonical encoding with a canonical encoding which additionally
should be faster.
Also fixes an issue where we used bincode in transcripts where it cannot be
trusted.
This ended up fixing a myriad of other bugs observed, unfortunately.
Accordingly, it either has to be merged or the bug fixes from it must be ported
to a new PR.
* Make serde optional, minimize usage
* Make borsh an optional dependency of substrate/ crates
* Remove unused dependencies
* Use [u8; 64] where possible in the processor messages
* Correct borsh feature flagging
Relevant to #394.
Prevents hand-over due to hand-over occurring via a `Batch` publication.
Expects a new protocol to restore functionality (after a retirement of the
current protocol).
* Move pallet-asset-conversion
* update licensing
* initial integration
* Integrate Currency & Assets types
* integrate liquidity tokens
* fmt
* integrate dex pallet tests
* fmt
* compilation error fixes
* integrate dex benchmarks
* fmt
* cargo clippy
* replace all occurrences of "asset" with "coin"
* add the actual add liq/swap logic to in-instructions
* add client side & tests
* fix deny
* Lint and changes
- Renames InInstruction::AddLiquidity to InInstruction::SwapAndAddLiquidity
- Makes create_pool an internal function
- Makes dex-pallet exclusively create pools against a native coin
- Removes various fees
- Adds new crates to GH workflow
* Fix rebase artifacts
* Correct other rebase artifact
* Correct CI specification for liquidity-tokens
* Correct primitives' test to the standardized pallet account scheme

Resolves#353
Implements code such that:
- 80% of validators (by stake) must be in favor of a signal for the network to
be
- 80% of networks (by stake) must be in favor of a signal for it to be locked
in
- After a signal has been locked in for two weeks, the network halts
The intention is to:
1) Not allow validators to unilaterally declare new consensus rules.
No method of declaring new consensus rules is provided by this pallet. Solely a
way to deprecate the current rules, with a signaled for successor. All nodes
must then individually decide whether or not to download and run a new node
which has new rules, and if so, which rules.
2) Not place blobs on chain.
Even if they'd be reproducible, it's just a lot of data to chuck on the
blockchain.
* initial implementation
* add function to get a balance of an account
* add support for multiple coins
* rename pallet to "coins-pallet"
* replace balances, assets and tokens pallet with coins pallet in runtime
* add total supply info
* update client side for new Coins pallet
* handle fees
* bug fixes
* Update FeeAccount test
* Fmt
* fix pr comments
* remove extraneous Imbalance type
* Minor tweaks

Adds Event::SetRetired to validator-sets.
Emit TributaryRetired.
Replaces is_active_set, which made multiple network requests, with
is_retired_tributary, a DB read.
Performs most of the removals necessary upon TributaryRetired.
Still needs to clean up the actual Tributary/Tendermint tasks.
* Revert "Correct the prior documented TOCTOU"
This reverts commit d50fe87801.
* Correct the prior documented TOCTOU
d50fe87801 edited the challenge for the Batch to
fix it. This won't produce Batch n+1 until Batch n is successfully published
and verified. It's an alternative strategy able to be reviewed, with a much
smaller impact to scope.
Now, if a malicious validator set publishes a malicious `Batch` at the last
moment, it'll cause all future `Batch`s signed by the next validator set to
require a bool being set (yet they never will set it).
This will prevent the handover.
The only overhead is having two distinct `batch_message` calls on-chain.
pre_dispatch is guaranteed by documentation to be called and persisted.
validate_unsigned is not, though the provided pre_dispatch does by default call
validate_unsigned. By explicitly providing our own pre_dispatch, we accomplish
the bounds we require and expect, only being invalidated on Substrate
redefining their API.
We should still test this, yet since we call retire_session in
validate_unsigned, any test of rotation will test it's being properly called.
Renames Update to SignedBatch.
Checks Batch equality via a hash of the InInstructions. That prevents needing
to keep the Batch in node state or TX introspect.
