Personally, I like this. Unlike restrictions on opcode behavior or witness data, it is impossible for there to be any existing UTXOs which "might turn out to need" scriptpubkeys greater than 520 bytes. In a post-covenant world I suppose this could change. There is a risk of confiscation of coins which have pre-signed but unpublished transactions spending them to new outputs with large scriptPubKeys. Due to long-standing standardness rules, and the presence of P2SH (and now P2WSH) for well over a decade, I'm skeptical that any such transactions exist. In any case, if confiscation is a worry, as always we can exempt the current UTXO set from the rule -- if you are only spending outputs that existed prior to the new rule, your new UTXOs are allowed to be large. I would even suggest going lower than 520 bytes. -- Andrew Poelstra Director, Blockstream Research Email: apoelstra at wpsoftware.net Web: https://www.wpsoftware.net/andrew The sun is always shining in space -Justin Lewis-Webster -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
