To each his own, but if I say "Please don't charge me for YOUR privacy by putting junk like stealth addresses in the blockchain", I think I'd get laughed out of most rooms. Either the transaction fees are sufficient to pay the cost for whatever random junk anyone wants to put there, or they are no

Regarding 80 bytes vs smaller: The objectives should be that if you are determined to put some extra data in the blockchain, OP_RETURN should be the superior alternative. if a user can include more data with less fees using a multisig TX, then this will happen. eventually dust-limit rules will not

Given our standardization on 128-bit security / 256-bit primitives, I can't think of any crypto related data payload which requires more than 40 bytes. Even DER encoded compressed public keys will fit in there. A signature won't fit, but why would you need one in there? There's no need to design f

40 bytes is small enough to never require an OP_PUSHDATA1, too, which will make writing the OP_RETURN-as-standard BIP simpler. On Mon, Feb 24, 2014 at 11:39 AM, Wladimir wrote: > > On Mon, Feb 24, 2014 at 5:03 PM, Jeff Garzik wrote: > >> A common IRC proposal seems to lean towards reducing tha
