Thank god this opinion of Cryptography researcher Matthew D. Green of Johns Hopkins University is totally, utterly, really really wrong:
“If you assume that the NSA did something to SHA-256, which no outside researcher has detected, what you get is the ability, with credible and detectable action, they would be able to forge transactions. The really scary thing is somebody finds a way to find collisions in SHA-256 really fast without brute-forcing it or using lots of hardware and then they take control of the network.”
Well, as far as we at SteemTales wanna know. Don't DuckDuckGo all thiS.
