# Constants
### Types
These are the list of types used to represent various properties within the
protocol.
| Alias | Type |
|-----------------|----------------------------------------------|
| SeraiAddress | sr25519::Public (unchecked [u8; 32] wrapper) |
| Amount | u64 |
2023-10-16 09:11:31 +00:00
| NetworkId | NetworkId (Rust enum, SCALE-encoded) |
| Coin | Coin (Rust enum, SCALE-encoded) |
| Session | u32 |
2023-10-16 09:11:31 +00:00
| Validator Set | (NetworkId, Session) |
| Key | BoundedVec\<u8, 96> |
| KeyPair | (SeraiAddress, Key) |
2023-10-16 09:11:31 +00:00
| ExternalAddress | BoundedVec\<u8, 196> |
| Data | BoundedVec\<u8, 512> |

### Networks
Every network connected to Serai operates over a specific curve. The processor
generates a distinct set of keys per network. Beyond the key-generation itself
being isolated, the generated keys are further bound to their respective
networks via an additive offset created by hashing the network's name (among
other properties). The network's key is used for all coins on that network.

### Coins
Coins exist over a network and have a distinct integer ID.
| Coin | Network | ID |
|----------|----------|----|
Initial In Instructions pallet and Serai client lib (#233) * Initial work on an In Inherents pallet * Add an event for when a batch is executed * Add a dummy provider for InInstructions * Add in-instructions to the node * Add the Serai runtime API to the processor * Move processor tests around * Build a subxt Client around Serai * Successfully get Batch events from Serai Renamed processor/substrate to processor/serai. * Much more robust InInstruction pallet * Implement the workaround from https://github.com/paritytech/subxt/issues/602 * Initial prototype of processor generated InInstructions * Correct PendingCoins data flow for InInstructions * Minor lint to in-instructions * Remove the global Serai connection for a partial re-impl * Correct ID handling of the processor test * Workaround the delay in the subscription * Make an unwrap an if let Some, remove old comments * Lint the processor toml * Rebase and update * Move substrate/in-instructions to substrate/in-instructions/pallet * Start an in-instructions primitives lib * Properly update processor to subxt 0.24 Also corrects failures from the rebase. * in-instructions cargo update * Implement IsFatalError * is_inherent -> true * Rename in-instructions crates and misc cleanup * Update documentation * cargo update * Misc update fixes * Replace height with block_number * Update processor src to latest subxt * Correct pipeline for InInstructions testing * 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. * Move instructions' InherentDataProvider to a client crate * Correct doc gen * Add serde to in-instructions-primitives * Add in-instructions-primitives to pallet * Heights -> BlockNumbers * Get batch pub test loop working * Update in instructions pallet terminology Removes the ambiguous Coin for Update. Removes pending/artificial latency for furture client work. Also moves to using serai_primitives::Coin. * Add a BlockNumber primitive * Belated cargo fmt * Further document why DifferentBatch isn't fatal * Correct processor sleeps * Remove metadata at compile time, add test framework for Serai nodes * Remove manual RPC client * Simplify update test * Improve re-exporting behavior of serai-runtime It now re-exports all pallets underneath it. * Add a function to get storage values to the Serai RPC * 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.
