When a message type has both a 1-byte encoding and a 13-byte encoding defined, peers that support receiving that message type should accept messages using either encoding (e.g., if the "getblocktxn" message type is supported, then both the 1-byte <code>b'\x0a'</code> encoding and the 13-byte <code>b'\x00getblocktxn\x00'</code> should be supported, and behavior should not depend on which of the two encodings is received).

Additional message type IDs may be added separately after BIP finalization. Additional message type IDs may be defined by other BIPs. They should be added to the [[bip-0324/message_type_ids.md|message type IDs table]] to ease coordination.

# One-byte message type allocations
This table lists additional message type IDs that various BIPs have
assigned or proposed for assignment.
Type | Message | Proposal
---- | ------------ | --------
n/a | n/a | (none listed yet)
Note that this table is not authoritative but instead is reflective
of the BIPs proposing the changes. If multiple BIPs make conflicting
assignments for message type IDs, that may lead to multiple entries for
the same message type ID in this table. BIPs that are in Draft status
may be included in the table, and as a result, the IDs and messages they
define may be changed in future.
