This topic is used to propagate signed blob sidecars, where each blob index maps to some `subnet_id`. However the actual blobs that will be generated by the EL will be limited by `MAX_DATA_GAS_PER_BLOCK // DATA_GAS_PER_BLOB` and will require an EL hardfork to upgrade the limit.
The following validations MUST pass before forwarding the `signed_blob_sidecar` on the network, assuming the alias `sidecar = signed_blob_sidecar.message`:
