Abstract: The tree (hierarchical) structure is one of the elementary memory arrangements, used by numerous data structures – ranging from simple to relatively sophisticated ones. The most well-known ...

EIP-7864 proposes replacing Ethereum’s hexary keccak tree with a binary structure, cutting Merkle branch size by 75%. Blake3 and Poseidon hash functions could accelerate Ethereum’s proving efficiency ...

Now that we’re getting into more complex data structures, having more complex operations, it’s helpful to have a tool for visualization. Here’s a tool developed by David Galles, formerly of University ...

A binary heap is a binary tree with two constraints: the heap order property and the structure property. The heap order property ensures that child nodes are always ordered with respect to their ...

ABSTRACT: In combinatorics, permutations are important objects with many operations. In this paper, we define a coupling product on permutations and prove that the space spanned by permutations is a ...

Merkle trees, also known as hash trees or binary hash trees, are tree-like data structures used in computer science. They are named after their inventor, Ralph Merkle, who proposed the concept in 1979 ...

Source Code for HappyCoders.eu article series on tree data structures (binary tree, binary search tree, AVL tree, red-black tree).

The Chinese state-backed hacking group Volt Typhoon is behind attacks that exploited a zero-day flaw in Versa Director to upload a custom webshell to steal credentials and breach corporate networks.
