My parents chose to try for kids during a time where global nuclear warfare was almost seen as a certainty.
There will always at all points in time be some doom scenario to worry about.
I mean, climate change is certainly happening. But i'd rather try and make a positive impact on things instead of feeling defeated. I'd rather go down fighting, with or without having kids.
Previously this timestamping was accredited by notaries. This had the problems of cost and the trust in a notary did not translate well internationally.
Now it is almost free to do and the cost of manipulating a blockchain (if possible at all) far outweighs the potential gain from malice.
I've been working with a company that uses a very common blockchain to timestamp documents/artwork/data etc.
It's a niche use case but it simply couldn't be done before the existance of blockchains.
It's really good. So called "dynamic contracts" with hourly pricing known only a day in advance are on the rise. Lots of people whithout access to solar can still benefit strongly this way by timing useage of things like washer/dryers etc. Lots of these devices are also becoming "smart" now to automatically pick a good pricing window.
Oof. That's looks very bad indeed. Is it oficially released yet? I've seen it before on beta/test versions of apps to ease debugging. Public release versions are usually very different regarding data collection needed.
