OP_PUSHDATA Opcodes Used in Name Operations?

[kefkius]

I wasn't sure where to post this, apologies if this is the wrong subforum.

In Bitcoin transactions, the opcode OP_PUSHDATA4 is used for the RIPEMD 160 hash of a key. In name operation scripts like

Code: Select all

OP_NAME_FIRSTUPDATE <identifier> <rand> <value> OP_2DROP OP_2DROP OP_DUP OP_HASH160 <Hash160> OP_EQUALVERIFY OP_CHECKSIG

and

Code: Select all

OP_NAME_UPDATE <identifier> <value> OP_2DROP OP_DROP OP_DUP OP_HASH160 <Hash160> OP_EQUALVERIFY OP_CHECKSIG

can one expect that OP_PUSHDATA4 is used for the identifier, rand, and value parameters? I can't find this anywhere.
