 #### Maximum blobs per block
 
-The max blob count is now provided and controlled by the CL during block production and a corresponding `max_blob_count` uint64 field is added to the header for purposes of optimistic sync validation of the maxmium versioned hashes a block can contain as well as for `excess_blob_gas` validations. This will supersed the [EIP-4844](./eip-4844.md) max blob gas validations.

This will supersede the [EIP-4844](./eip-4844.md) max blob gas validations.
 
 #### Target blobs per block
 
 The target is currently specified as a fixed value in relation to the blob count. The Ethereum community intends to increase the blob parameters as part of its scaling strategy and the ability to have a more flexible target value in relation to the blob max is desirable to reduce rigidity in this protocol parameter.
 
-To this end similar to `max_blob_count`, CL now provides a blob count target as well during block production and the EL block header is extended with this `target_blob_count` value to preserve the security of optimistic sync for the purposes validations of `excess_blob_gas`.
