       "Bitcoin "mining" is equivalent to the job of digging a hole and filling it back up."When you connect to a blockchain, how do you know a hacker isn't in your computer/router/isp giving you fake blocks?If you rely on a source to tell you where to connect, that blockchain is centralized.If you give me one #Bitcoin block, I know it is authentic. The cryptographic puzzle solved in this block is so hard, that there is only 1 computer system in the world that could have solved it: #Bitcoin

       This is a test for proof of stake blockchains.No matter how complicated, ask the proponent "How do I know for sure I'm connected to your POS chain?"This question, cuts through all the complicated mumbo-jumbo in a POS white-paper.The only solution for POS blockchains is to have an authoritative source for connecting to the chain. There is no way to simply look at a POS block and know it is authentic. It's not inherent in the block.You are open to hackers with POS, unless you centralize.

       @alanturing That’s why it’s a POS.
