https://twitter.com/nickgiambruno/status/1307389546561179653A trillion seconds ago was 30,000 B.C.
A quadrillion seconds ago was 32 million years ago.
A quintillion seconds ago was 32 billion years ago. (The age of the universe is 13.8 billion years.)
The computing power that secures Bitcoin is 139 quintillion calculations PER SECOND.
So, according to the above numbers, it takes only about
3 milliseconds (0.003 seconds) for the Bitcoin network to perform as many calculations as there are seconds since the birth of the universe!
In other words, in every second that passes, the above process is repeated more than 300 times!
Wow! Just WOW!
thatiswowindeed! 139 quintillion calculations per second, but only 7 transactions made in that that same time. this is the polar opposite of efficiency. it shows how much of the power of this network goes into security and protection of those 7 transactions.
we are trained for efficiency. no matter what we do, we try to do it more efficiently next time. bitcoin is different. it gives up efficiency completely to ensure maximum security. that is counter-intuitive and makes it hard to understand and is one of the reasons for the existence of shitcoinery: "my blockchain is faster.."
the bitcoin algorithm is a monster. secured by 139 quintillion calculations per 7 transactions.
if you want to build a tank the equivalent thickness of the steel used would need to be 500yards. moves slow but no weapon existing could penetrate it, not even in theory.
