# Scanning
|
|
|
|
Only blocks with finality, either actual or sufficiently probabilistic, are
|
|
operated upon. This is referred to as a block with `CONFIRMATIONS`
|
|
confirmations, the block itself being the first confirmation.
|
|
|
|
For chains which promise finality on a known schedule, `CONFIRMATIONS` is set to
|
|
`1` and each group of finalized blocks is treated as a single block, with the
|
|
tail block's hash representing the entire group.
|
|
|
|
For chains which offer finality, on an unknown schedule, `CONFIRMATIONS` is
|
|
still set to `1` yet blocks aren't aggregated into a group. They're handled
|
|
individually, yet only once finalized. This allows networks which form
|
|
finalization erratically to not have to agree on when finalizations were formed,
|
|
solely that the blocks contained have a finalized descendant.
|
|
|
|
### Notability, causing a `Batch`
|
|
|
|
`Batch`s are only created for blocks which it benefits to achieve ordering on.
|
|
These are:
|
|
|
|
- Blocks which contain transactions relevant to Serai
|
|
- Blocks which in which a new multisig activates
|
|
- Blocks in which a prior multisig retires
|
|
|
|
### Waiting for `Batch` inclusion
|
|
|
|
Once a `Batch` is created, it is expected to eventually be included on Serai.
|
|
If the `Batch` isn't included within `CONFIRMATIONS` blocks of its creation, the
|
|
scanner will wait until its inclusion before scanning
|
|
`batch_block + CONFIRMATIONS`.
