Guys I've been thinking about this recently
So the telegraph has existed for a while, and became widespread in 1800s. Charles Babbage worked on the first mechanical #computers in the 1820s

What would be the earliest point in time in which a #Bitcoin like #Blockchain could've been made?

As I understand it all the system needs is a #network of computers each running a program that checks for transactions

I'm wondering if a different hash function was used it could be a lot simpler to implement into hardware, but if mechanical computing wasn't powerful enough for that the earliest might've been after WWII with the code breaking machines that the Allies invented

Any boosts would be greatly appreciated!

hello everyone.

In today's article, we examine many topics with Python hashlib and create great projects with examples.

Finally fully grok hash length extension/padding attacks. So I wrote a play-along guide, in case it helps others get their head around this gnarly cybersecurity concept:

@skye We can gain some insights from benchmarks of other known systems. this answer [crypto.stackexchange.com] for instance quantifies #security levels by measuring the effort needed to do a similar number of #hash operations as is denoted by the "security level" of a #cryptographic system.

So, let's say the "super computer" is all of the bitcoin miners on Earth today. They can do more than 2⁹² hashes a year. Let's make them 16 million times more powerful. 16 million is 2^24. So, they'd be able to do more than 2⁹² x 2²⁴ = 2¹¹⁶ hashes a year. So, if these super miners were to try to guess the key for a single encrypted message that used a cipher with 128-bit security, then after a year of trying, they'd only have a 2^-12 (or 1 / 4096) chance of finding the correct key.

(Passwords)[https://en.wikipedia.org/wiki/Argon2] are way easier to guess than (cryptographic)[https://en.wikipedia.org/wiki/Key_(cryptography)] keys, so (memory-hard)[https://en.wikipedia.org/wiki/Memory-hard_function] functions are often used to make it more difficult.
