Yesterday evening, an individual(at a french meetup haha) asked me what ethereum was and kept asking me if there was something similar to MIME types on Ethereum. I did not know what MIME types were and so asked and he said 'It's part of a specification that standardizes the nature and format of a document).
The reason for this question was, if someone were to say, scan through the blockchain running any code that looks familiar(say, starts with html) but was malicious, there would be no way of knowing.
Is there any reason to be concerned about this? Is there a way this can/is already circumvented?(I'm thinking an EIP)
He also mentioned NATSPEC's efforts in trying to do something similar for browsers
