Comments for the Partially Signed Transaction Format
# Comments for the Partially Signed Transaction Format
* Partial signature entries use the map key `{0x02}|{public key}`. However, a single public key may be involved in signing multiple inputs, and the signature will differ in each one. Since the map keys are to be unique, this is a problem. I suggest the following map key instead: `{0x02}|{input index}|{pubkey index}`
* HD derivation entries waste space by repeating the public key. I recommend using the following map key instead: `{0x03}|{input index}|{pubkey index}`, which also matches previous point.
