## Specification

### Block Body

Define `requests` as an empty array:
### Requests
A `requests` object consists of a `request_type` prepended to an opaque byte array `request_data`.
```golang
requests = make(types.Requests, 0)
requests = request_type ++ request_data
```
Each request type will defines its own `requests` object using with its own `request_data` format.

### Block Header

In accordance with EIP-7685, add `requests_hash` to the end of the block header:
In accordance with EIP-7685, add a new 32 byte value `requests_hash` to the end of the block header:
```golang
def compute_requests_hash(requests):
m = sha256()
for r in requests:
m.update(sha256(r))
return m.digest()

requests = make(types.Requests, 0) // empty request for BSC
block.header.requests_hash = compute_requests_hash(requests)
```
When calculating the header signature, ensure that requests_hash is included in the computation.
