Hashing transforms data into a fixed-length cryptographic fingerprint that ensures integrity and authenticity. Every block in a blockchain contains its own hash and the previous block’s hash, forming ...

Abstract: Due to the powerful feature extraction capabilities of deep neural networks (DNNs), deep image hashing has extensive applications in the fields such as image authentication, copy detection ...

As we have seen in previous videos, it happens sometimes that two keys yield the same hash value for a given table size. This is called a “hash collision” or just “collision.” Why do hash collisions ...

A security flaw has been disclosed in OpenWrt's Attended Sysupgrade (ASU) feature that, if successfully exploited, could have been abused to distribute malicious firmware packages. The vulnerability, ...

While the last year or two have seen a number of proposals for covenant-proposing extensions to Bitcoin, there has always been a suspicion among experts that covenants may be possible without any ...
