* Update `build-dependencies` CI action
* Update `develop` to `patch-polkadot-sdk`
Allows us to finally remove the old `serai-dex/substrate` repository _and_
should have CI pass without issue on `develop` again.
The changes made here should be trivial and maintain all prior
behavior/functionality. The most notable are to `chain_spec.rs`, in order to
still use a SCALE-encoded `GenesisConfig` (avoiding `serde_json`).
* CI fixes
* Add `/usr/local/opt/llvm/lib` to paths on macOS hosts
* Attempt to use `LD_LIBRARY_PATH` in macOS GitHub CI
* Use `libp2p 0.56` in `serai-node`
* Correct Windows build dependencies
* Correct `llvm/lib` path on macOS
* Correct how macOS 13 and 14 have different homebrew paths
* Use `sw_vers` instead of `uname` on macOS
Yields the macOS version instead of the kernel's version.
* Replace hard-coded path with the intended env variable to fix macOS 13
* Add `libclang-dev` as dependency to the Debian Dockerfile
* Set the `CODE` storage slot
* Update to a version of substrate without `wasmtimer`
Turns out `wasmtimer` is WASM only. This should restore the node's functioning
on non-WASM environments.
* Restore `clang` as a dependency due to the Debian Dockerfile as we require a C++ compiler
* Move from Debian bookworm to trixie
* Restore `chain_getBlockBin` to the RPC
* Always generate a new key for the P2P network
* Mention every account on-chain before they publish a transaction
`CheckNonce` required accounts have a provider in order to even have their
nonce considered. This shims that by claiming every account has a provider at
the start of a block, if it signs a transaction.
The actual execution could presumably diverge between block building (which
sets the provider before each transaction) and execution (which sets the
providers at the start of the block). It doesn't diverge in our current
configuration and it won't be propagated to `next` (which doesn't use
`CheckNonce`).
Also uses explicit indexes for the `serai_abi::{Call, Event}` `enum`s.
* Adopt `patch-polkadot-sdk` with fixed peering
* Manually insert the authority discovery key into the keystore
I did try pulling in `pallet-authority-discovery` for this, updating
`SessionKeys`, but that was insufficient for whatever reason.
* Update to latest `substrate-wasm-builder`
* Fix timeline for incrementing providers
e1671dd71b incremented the providers for every
single transaction's sender before execution, noting the solution was fragile
but it worked for us at this time. It did not work for us at this time.
The new solution replaces `inc_providers` with direct access to the `Account`
`StorageMap` to increment the providers, achieving the desired goal, _without_
emitting an event (which is ordered, and the disparate order between building
and execution was causing mismatches of the state root).
This solution is also fragile and may also be insufficient. None of this code
exists anymore on `next` however. It just has to work sufficiently for now.
* clippy
Adds a deny entry for `is-terminal` to stop it from secretly reappearing.
Restores the `is-terminal` patch for `is_terminal_polyfill` to have one less
external dependency.
This helps identify where the various functionalities are used, or rather, not
used. The `Ciphersuite` trait present in `patches/ciphersuite`, facilitating
the entire FCMP++ tree, only requires the markers _and_ canonical point
decoding. I've opened a PR to upstream such a trait into `group`
(https://github.com/zkcrypto/group/pull/68).
`WrappedGroup` is still justified for as long as `Group::generator` exists.
Moving `::generator()` to its own trait, on an independent structure (upstream)
would be massively appreciated. @tarcieri also wanted to update from
`fn generator()` to `const GENERATOR`, which would encourage further discussion
on https://github.com/zkcrypto/group/issues/32 and
https://github.com/zkcrypto/group/issues/45, which have been stagnant.
The `Id` trait is occasionally used yet really should be first off the chopping
block.
Finally, `WithPreferredHash` is only actually used around a third of the time,
which more than justifies it being a separate trait.

Updates `dalek_ff_group::Scalar` to directly re-export
`curve25519_dalek::Scalar`, as without issue. `dalek_ff_group::RistrettoPoint`
also could be replaced with an export of `curve25519_dalek::RistrettoPoint`,
yet the coordinator relies on how we implemented `Hash` on it for the hell of
it so it isn't worth it at this time. `dalek_ff_group::EdwardsPoint` can't be
replaced for an re-export of `curve25519_dalek::SubgroupPoint` as it doesn't
implement `zeroize`, `subtle` traits within a released, non-yanked version.
Relevance to https://github.com/serai-dex/serai/issues/201 and
https://github.com/dalek-cryptography/curve25519-dalek/issues/811#issuecomment-3247732746.
Also updates the `Ristretto` ciphersuite to prefer `Blake2b-512` over
`SHA2-512`. In order to maintain compliance with FROST's IETF standard,
`modular-frost` defines its own ciphersuite for Ristretto which still uses
`SHA2-512`.
Actually use the added `Allocations` abstraction
Start using the sessions API in the validator-sets pallet
Get a `substrate/validator-sets` approximate to compiling
Enables representing IUMT within `StorageValues`. Applied to a variety of
values.
Fixes a bug where `Some([0; 32])` would be considered a valid block anchor.
The reasoning for it is documented with itself. The plan is to use it within
our header for committing to the DAG (allowing one header per epoch, yet
logarithmic proofs for any header within the epoch), the transactions
commitment (allowing logarithmic proofs of a transaction within a block,
without padding), and the events commitment (allowing logarithmic proofs of
unique events within a block, despite events not having a unique ID inherent).
This also defines transaction hashes and performs the necessary modifications
for transactions to be unique.
This does break borsh's definition of a Vec EXCEPT if the BoundedVec is
considered an enum. For sufficiently low bounds, this is viable, though it
requires automated code generation to be sane.
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-present `Ciphersuite::hash_to_F` was a sin. Implementations took a
DST, yet were not require to securely handle it. It was also biased towards the
requirements of `modular-frost` as `ciphersuite` was originally written all
those years ago, when `modular-frost` had needs exceeding what `ff`, `group`
satisfied.
Now, the hash is bound to produce an output which can be converted to a scalar
with `ff::FromUniformBytes`. A new `hash_to_F`, which accepts a single argument
of the value to hash (removing the potential to insecurely handle the DST by
removing the DST entirely). Due to `digest` yielding a `GenericArray`, yet
`FromUniformBytes` taking a `const usize`, the `ciphersuite` crate now defines
a `FromUniformBytes` trait taking an array (then implemented for all satisfiers
of `ff::FromUniformBytes`). In order to get the array type from the
`GenericArray`, the output of the hash, `digest` is updated to the `0.11`
release candidate which moves to `flexible-array` which solves that problem.
The existing, specific `hash_to_F` functions have been moved to `modular-frost`
as necessary.
`flexible-array` itself is patched to a fork due to
https://github.com/RustCrypto/hybrid-array/issues/131.
