## Differences with Ethereum mainnet

### [EIP-7691](https://eips.ethereum.org/EIPS/eip-7691)

The blob gas target and max is kept equal to the Dencun hard-fork.

| Constant | Value |
| ------------------------------------ | ----- |
| MAX_BLOBS_PER_BLOCK_ELECTRA | 2
| TARGET_BLOBS_PER_BLOCK_ELECTRA | 1
| MAX_BLOB_GAS_PER_BLOCK | 262144
| TARGET_BLOB_GAS_PER_BLOCK | 131072
| BLOB_BASE_FEE_UPDATE_FRACTION_PRAGUE | 5007716

### [EIP-4844-pectra](https://eips.ethereum.org/EIPS/eip-4844)

Extends the modified Gnosis EIP-4844 as defined in the [dencun spec](../dencun.md) document. Starting at the fork timestamp, the blob base fee is collected instead of burned.
