## Introduction
|
||
|
|
|
||
|
|
This is the modification of the fork choice according to EIP-6914.
|
||
|
|
|
||
|
|
## Fork choice
|
||
|
|
|
||
|
|
A new handler is added with this upgrade:
|
||
|
|
|
||
|
|
- `on_reused_index(store, index)` whenever a validator index `index: ValidatorIndex` is reused
|
||
|
|
|
||
|
|
This new handler is used to update the list of equivocating indices to be synchronized with the canonical chain.
|
||
|
|
|
||
|
|
### Handlers
|
||
|
|
|
||
|
|
#### `on_reused_index`
|
||
|
|
|
||
|
|
```python
|
||
|
|
def on_reused_index(store: Store, index: ValidatorIndex) -> None:
|
||
|
|
store.equivocating_indices.discard(index)
|
||
|
|
```
