I think Steemit is making a huge mistake assuming their bodged Proof-of-Stake (Delegated) is good enough to bolt on the extra requirements of a "second layer" to begin with.

The stop-and-decrypt article is excellent, I suggest reading it here -- https://hackernoon.com/asic-resistance-is-nothing-but-a-blockchain-buzzword-b91d3d770366

So is this article on why PoS is a dumpster fire -- https://medium.com/@hugonguyen/proof-of-stake-the-wrong-engineering-mindset-15e641ab65a2

As you guys bolt more stuff on top of a chain that already had problems dealing with "edge cases", I'm not holding my breath for the next "incident" where its all explained away as something that "doesn't really happen too much".

Its bad base assumptions that trickle up to your upper layers, and will cause all kinds of problems if it ever gains any real usage.

Don't say I didn't warn you...
