I was wrong about my initial impression but also possibly on to something as it pertains to the hash tree that could be created with Blake.
Hash / Merkle Tree Concept
Rather than just creating an appended list (sort of like blockchain) and then adding an additional operation that merely hashes the last input, it feels like it would be prudent to have all of the values hashed together in some capacity.
So that means:
1) H = x
2) H(x)
3) H(H(X))
4) H(H(H(X)))
There's something that's missing in this construction.
Only way that this could work is if the generator of the hash chain kept at least a few values secret.
But it is impossible for this to be done in a way where all of those values are kept secret and this be seen as externally valid.
The only other way is to ensure that all of the values are public. But if you must do that then you need to devise another method that will require people to remain honest bc you've trapped off their avenues for "cheating".
This is why the write-up on the way that time is calculated on the blockchain is extremely fucking important - it is an objective source of randomness that keeps everyone honest if it can be adhered to.
The idea that I had about the UNIX time tracking was interesting, but ultimately one critical underpinning here (hmm...)

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
Spiking bond yields driving sharp losses in tech stocks
A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year.
A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
