I don't dispute that there is real innovation with the blockchain -- just that the level of innovation cannot alone justify the value of or interest in cryptocurrency. To answer your question: linked timestamping[1][2] does, in fact, solve this problem -- and solved this problem long before the blockchain. Again, not disputing that the blockchain doesn't allow one to prove tamper-proof transaction systems or that this isn't an important problem -- just that it's not the first technology to do it, isn't the only way to do it, and doesn't alone pay the freight for the level of interest in cryptocurrency.
