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.
"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
If you think I'll sit around you chip away my brain
Listen I ain't foolin' and you'd better think again
Out there is a fortune waitin' to be had
You think I'll let it go you're mad, you've got another thing comin'
Aim for a new tomorrow
And oh so hot no time to take a rest yeah
Act tough ain't room for second best
Real strong got me some security
Hey I'm a big hash I'm goin' for infinity yeah
