* Partial move to ff 0.13 It turns out the newly released k256 0.12 isn't on ff 0.13, preventing further work at this time. * Update all crates to work on ff 0.13 The provided curves still need to be expanded to fit the new API. * Finish adding dalek-ff-group ff 0.13 constants * Correct FieldElement::product definition Also stops exporting macros. * Test most new parts of ff 0.13 * Additionally test ff-group-tests with BLS12-381 and the pasta curves We only tested curves from RustCrypto. Now we test a curve offered by zk-crypto, the group behind ff/group, and the pasta curves, which is by Zcash (though Zcash developers are also behind zk-crypto). * Finish Ed448 Fully specifies all constants, passes all tests in ff-group-tests, and finishes moving to ff-0.13. * Add RustCrypto/elliptic-curves to allowed git repos Needed due to k256/p256 incorrectly defining product. * Finish writing ff 0.13 tests * Add additional comments to dalek * Further comments * Update ethereum-serai to ff 0.13 |

Processor
The Serai processor scans a specified chain, communicating with the coordinator.
Key Generation
The coordinator will tell the processor if it's been included in managing a coin. If so, the processor is to begin the key generation protocol, relying on the coordinator to provided authenticated communication with the remote parties.
When the key generation protocol successfully completes, the processor is expected to inform the coordinator so it may vote on it on the Substrate chain. Once the key is voted in, it'll become active.
Scanning
The processor is expected to scan all sufficiently confirmed blocks from a given coin. This will create a list of outputs, considered pending.
Reporting
These outputs are to be placed in a Batch, identified by the block containing
them. Batches are provided in an Update to Serai, paired by an agreed upon
block number.
The processor will also produce an Update if there have been no batches within
the confirmation window.
Confirmed Outputs
Once outputs have been acknowledged by Serai, they are considered confirmed. With their confirmation, the validators are ready to create actions based on them.
Actions are triggered by passing the outputs to the scheduler. The scheduler will do one of two things:
- Use the output
- Accumulate it for later usage
Burn Events
When the Serai chain issues a Burn event, the processor should send coins
accordingly. This is done by scheduling the payments out.
TODO
- Acknowledging a sign ID as signed so we don't continue trying
monero-serai now supports Eventualitys. When we have a plan to attempt,
we can create an Eventuality and see if it matches a given TX. A signing node
just has to submit the TX hash.
Bitcoin will have the same TX hash flow, just explicitly matching against the inputs.
- Coordinator communication
Kafka? RPC ping to them, which we don't count as 'sent' until we get a pong?
