4844 Links 🔗

By: terencechain

Background

EIP-4844 introduces a new kind of transaction type to Ethereum, which accepts "blobs" of data to be persisted in the beacon node for a short period of time. These changes are forwards compatible with Ethereum's scaling roadmap, and blobs are small enough to keep disk use manageable. Here are all the relevant links with descriptions

Changes to the execution client and consensus layer client are specified in the EIP, and the beacon chain specs are here

// Problem: COMPUTE THE LONGEST CONTIGUOUS INCREASING SUBARRAY
//
// An array is increasing if each element is less than its succeeding element except for the last element.
// Implement an algorithm that takes as input an array A of n elements,
// and returns the beginning and ending indices of a longest increasing subarray of A.
//
// For example, if A =(2,11,3,5,13,7,19,17,23),
// the longest increasing subarray is (3,5,13), and you should return (2,4)

// Problem: Sum Swap
//
// Given two array of integers, find a pair of values (one value from each array) that you can swap
// to give the two arrays the same sum.
//
// Input:{4,1,2,1,1,2} and {3, 6, 3, 3}
// Output: {1, 3}

Background:

I want to take advantage of up-coming black friday sales and build a staking box for eth2

Goal:

Less than $800 USD. 8 cores, 32GB, 1TB SSD

CPU:

Intel® Core™ i7-9700K
Price: $299.98 on Amazon.
Rationale: I want at least 8 cores.
