 ## 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.
