Apparently no one has told him that a blockchain is just a data structure and has nothing to do with proof of work.

- icebraining 9y agoNo, that's just a hash chain, and it has existed for decades, long before the blockchain ever appeared. For example, every POS software in my country was legally required to implement that before the Bitcoin paper was published. The blockchain is a particular implementation of an hash chain, designed to work well for transactions using some sort of distributed consensus algorithm (of which proof-of-work is a category).
