Turns out, if you add point A a lot of times (in other words, multiply it by a large enough number) and get another point B, it will be hard to figure out what that number was, provided you are given only the original point A and the resulting point B.
the main innovation of cryptocurrency is that you can keep this digital record on all the computers on a peer to peer network without having to rely on a central authority to prevent any of the peers from double spending their balance.
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network.
Apple will ask you whether your app uses the IDFA. Because Expo depends on Segment Analytics, the answer is yes, and you’ll need to check a couple boxes on the Apple submission form. See Segment’s Guide for which specific boxes to fill in.

In terms of monetary policy, Bitcoin is the greatest money the world has ever seen.
For the second time in months, Verge XVG is being hacked by generating fake timestamps to lower the difficulty adjustment algorithm so as to monopolize the mining of new coins. Attack is made possible due to the larger attack surface of Verge's relatively sophisticated design.
If the protocol were sentient and fluent in English, it would be saying something like “Oh no! Not enough blocks have been submitted recently! Mining must be too difficult — let’s make it easier!” Since timestamps were continuously being spoofed, the protocol continuously lowered the difficulty, until mining got laughably easy.
Over a dissent from Justice Sonia Sotomayor that was joined by Justice Ruth Bader Ginsburg, the Supreme Court last night declined to block the executions of three Ohio men. One of the inmates, Ronald Phillips, is scheduled to be put to death today for the 1993 rape and murder of his girlfriend’s daughter.
Phillips and the other two inmates, Gary Otte and Raymond Tibbetts, had challenged the three-drug protocol that the state plans to use to carry out their executions, arguing that it violates the Eighth Amendment’s ban on cruel and unusual punishment.
