Love the logo
Only comment - Lose the glass effect under the ticks, not sure that works, and the line under Meet Black, otherwise looks really nice

There's a typo >Millon should be Million.
And maybe it could read 1% interest yearly?
DONE!
looks great. I'd also suggest maintaining consistency with capitalization of the words.

"Proof of stake - unminable"
"1% yearly interest"
"First confirmation within 30 seconds" (if too long: skip "first")
And skip the capitalization of every word.
