The argument that optional fields can be omitted is not applicable to required fields, you are correct. That should be rather obvious because required fields are not optional fields. > the code to get the > fields from the extensible format is every bit as complex as the very > simple code required to deserialize/serialize objects in the current > system. Probably a tiny bit more complex as the current format assumes a lot more. You may have misread my email because there was no argument made towards complexity. The argument was towards flexibility. > In any case your BIP needs to give some explicit examples of hypothetical > upgrades in the future, how they'd take advantage of this, and what the > code to do so would look like.

Please consider that I'm not going to search for something based on a vague reference like that, if you want to convince me you could you at least provide a URL? You want me to see the value of your idea, I think you should at least provide the argument. Isn't that fair? Thanks for your email Peter, would love you to put a bit more time into understanding flexible transactions and we can have a proper discussion about it. _______________________________________________ bitcoin-dev mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
