Learn how hashing secures blockchain data, powers mining, and protects crypto networks from tampering and fraud.

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

In the current digital landscape, data integrity and security have taken center stage, especially as businesses and institutions continue to depend on digital data. This reliance, however, brings its ...

The network hash rate jumped 31.69% — from 188.40 EH/s to 248.11 EH/s — in just one day, further ensuring resilience against attacks on the Bitcoin network. The Bitcoin network recorded a new hash ...

Many discussions of “hybrid encryption” begin with some debate about just what this means. Hybrid encryption in general refers to the combined use of public-key (asymmetric) cryptography with ...

In the movies, hackers typically enter a few keystrokes and gain access to entire networks in a matter of seconds. In the real world however, attackers often start out with nothing more than a ...

Randomness is hard. To be precise, without dedicated hardware, randomness is impossible for a computer. This is actually important to keep in mind when writing software. When there’s not ...

Computing resources dedicated to Bitcoin transaction validation is bigger than ever, underscoring miners’ overall bullish sentiment despite the price falling. This is the largest reading ever and ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...
