Instead of getting lost, attempting to understand the trade-offs in blockchain security between Proof of Work and Proof of Stake algorithms, instead of figuring out the pros and cons of on-chain versus off-chain transactions, and instead of falling down a technical black hole when reading about the loss of Byzantine fault tolerance when sharding a protocol and moving from single to parallel threading, allowing the protocol to run in parallel, start with three high-level questions.

What real-world problem does this cryptocurrency or blockchain technology solve?

Is the technology scalable?

Who are the developers?
