## Introduction
|
||||
|
||||
This document describes how to upgrade existing light client objects based on the [Deneb specification](../../deneb/light-client/sync-protocol.md) to eip7002. This is necessary when processing pre-eip7002 data with a post-eip7002 `LightClientStore`. Note that the data being exchanged over the network protocols uses the original format.
|
||||
|
||||
### Upgrading light client data
|
||||
|
||||
A eip7002 `LightClientStore` can still process earlier light client data. In order to do so, that pre-eip7002 data needs to be locally upgraded to eip7002 before processing.
|
||||
|
||||
```python
|
||||
def upgrade_lc_header_to_eip7002(pre: deneb.LightClientHeader) -> LightClientHeader:
|
||||
return LightClientHeader(
|
||||
beacon=pre.beacon,
|
||||
execution=ExecutionPayloadHeader(
|
||||
parent_hash=pre.execution.parent_hash,
|
||||
fee_recipient=pre.execution.fee_recipient,
|
||||
state_root=pre.execution.state_root,
|
||||
receipts_root=pre.execution.receipts_root,
|
||||
logs_bloom=pre.execution.logs_bloom,
|
||||
prev_randao=pre.execution.prev_randao,
|
||||
block_number=pre.execution.block_number,
|
||||
gas_limit=pre.execution.gas_limit,
|
||||
gas_used=pre.execution.gas_used,
|
||||
timestamp=pre.execution.timestamp,
|
||||
extra_data=pre.execution.extra_data,
|
||||
base_fee_per_gas=pre.execution.base_fee_per_gas,
|
||||
block_hash=pre.execution.block_hash,
|
||||
transactions_root=pre.execution.transactions_root,
|
||||
withdrawals_root=pre.execution.withdrawals_root,
|
||||
excess_data_gas=pre.execution.excess_data_gas,

||||
exits_root=Root(), # [New in EIP7002]
|
||||
),
|
||||
execution_branch=pre.execution_branch,
|
||||
)
|
||||
```
|
||||
|
||||
```python
|
||||
def upgrade_lc_bootstrap_to_eip7002(pre: deneb.LightClientBootstrap) -> LightClientBootstrap:
|
||||
return LightClientBootstrap(
|
||||
header=upgrade_lc_header_to_eip7002(pre.header),
|
||||
current_sync_committee=pre.current_sync_committee,
|
||||
current_sync_committee_branch=pre.current_sync_committee_branch,
|
||||
)
|
||||
```
|
||||
|
||||
```python
|
||||
def upgrade_lc_update_to_eip7002(pre: deneb.LightClientUpdate) -> LightClientUpdate:
|
||||
return LightClientUpdate(
|
||||
attested_header=upgrade_lc_header_to_eip7002(pre.attested_header),

```python
|

def upgrade_lc_optimistic_update_to_eip7002(pre: deneb.LightClientOptimisticUpdate) -> LightClientOptimisticUpdate:
|
||||
return LightClientOptimisticUpdate(

|
||||
sync_aggregate=pre.sync_aggregate,
|
||||
signature_slot=pre.signature_slot,
|
||||
)
|
||||
```
|
||||
|
||||
### Upgrading the store
|
||||
|
||||
Existing `LightClientStore` objects based on Deneb MUST be upgraded to eip7002 before eip7002 based light client data can be processed. The `LightClientStore` upgrade MAY be performed before `EIP7002_FORK_EPOCH`.
|
||||
|
||||
```python
|
||||
def upgrade_lc_store_to_eip7002(pre: deneb.LightClientStore) -> LightClientStore:
|
||||
if pre.best_valid_update is None:
|
||||
best_valid_update = None
|
||||
else:
|
||||
best_valid_update = upgrade_lc_update_to_eip7002(pre.best_valid_update)
|
||||
return LightClientStore(
|
||||
finalized_header=upgrade_lc_header_to_eip7002(pre.finalized_header),
|
||||
current_sync_committee=pre.current_sync_committee,
|
||||
next_sync_committee=pre.next_sync_committee,
|
||||
best_valid_update=best_valid_update,
|
||||
optimistic_header=upgrade_lc_header_to_eip7002(pre.optimistic_header),
|
||||
previous_max_active_participants=pre.previous_max_active_participants,
|
||||
current_max_active_participants=pre.current_max_active_participants,
|
||||

## Introduction
|
||||
|
||||
This upgrade updates light client data to include the EIP-7002 changes to the [`ExecutionPayload`](../beacon-chain.md) structure. It extends the [Deneb Light Client specifications](../../deneb/light-client/sync-protocol.md). The [fork document](./fork.md) explains how to upgrade existing Deneb based deployments to EIP-7002.
|
||||
|
||||
Additional documents describes the impact of the upgrade on certain roles:
|
||||
- [Full node](./full-node.md)
|
||||
- [Networking](./p2p-interface.md)
