Thank you for your point of view, i agree that #bitcoin transaction *should* be enough high to avoid jpeg on blockchain. But we are not speaking only about jpeg but every other use that could delay transactions. Nakamoto has a vision for #bitcoin and he explained and made his vision a reality. We are not "fighting" here to know if a block can handle or not some extra data like jpeg. We are "fighting" here to know if the blockchain is enough secure for futures attacks. You know attacks like "put your birthdate and name on the blochain for 15$" for the newbee. And the operator that want to do that just need few space for 15$ to do it (but with a lot of customer it could take a lot of space in a block). Perhaps it is a stupid example. Perhaps it will not happen this way. But be sure that if there is no filter and just a "hope" that spam will be stopped by fees, it is a big lack of vision. #bitcoin is used to transfer value from a wallet to another, it has be built for this use and it is more and more use for this with time. If you don't have any vision about how to preserve that, it will be a huge danger for the legit transactions in future. When the perfect high value spam will delay legit transactions because they will find a way to make their spam enough valuable to be push in the blockchain. And it is not acceptable that fees would be over-high for legit transactions. I am not saying you can't put "extra data" on the blockchain, but it MUST be a way to preserve legit transaction and not only rely on fees. It is a lack of vision to just "hope" it will be enough. Thanks for your share. #btc4ever
