I recently moved my Blockchain Protocol Development Guide to its own site: Blockchain Protocol Development Guide.

The use case is as follows: You have some tasks you want to execute concurrently, but you want the results to be returned in the same order the tasks were defined to be executed.

I took a break from exploring development in Solana, and the first thing I hit when I recently resumed again was failing tests when using the Anchor framework.

Types, loosely defined, are about capabilities.

This post will give a quick overview of declarative macros in Rust.

This guide will present an overview of the fundamentals a new developer approaching macros in Rust needs to know.

This post shows how to query Solana's cluster rpc endpoint using Rust.

In Rust Iterator pattern with iter(), into_iter() and iter_mut() methods I explained why attempting to use a variable holding a Vec after iterating through it using the for … in syntax leads to a compilation error.

Let's create a vec of integers, iterate through and print the individual values, and then afterward, print out the whole vec.

In this post, we would be looking at digital signatures.

In this post, we are going to look at asymmetric encryption.

The truth of the matter is, the async/await features in other programming languages seem to be more straightforward than it is in Rust.

In Introduction to Symmetric Encryption for the Working Developer, we saw how to encrypt and decrypt data.

In Introduction to Symmetric Encryption for the Working Developer, I presented an overview of symmetric encryption.

Encryption is all about establishing confidentiality.

In Introduction to Cryptographic Hash Functions for the Working Developer, I presented a straight to the point, overview of some essential things a developer should know about cryptographic hash functions.

Much more than encryption algorithms, one-way hash functions are the workhouses of modern cryptography - Bruce schneier This post would be a quick, straight to the point, overview of some essential things a developer should know about cryptographic hash f…

Non-equity funding campaigns are always based on promises: "Back us now, and we promise you early access to the product when we launch, or we promise you a discount, digital shout-out or swags".

This post will be the conlcuding post in the Introduction to Advanced Types in TypeScript series.

PlanetTypeScript.com is a content aggregator for all things TypeScript.

TypeScript type's system is structural and hence, it allows for the easy creation of types based on the shape of data.

Most popular mainstream languages have a sleep functionality that allows for the pausing of code execution for a specified amount of time.

This post is going to show, by way of code examples, how to take a callback based API, modify it to use Promises and then use the Async/Await syntax.

ip-num is A TypeScript/JavaScript library for working with ASN, IPv4, and IPv6 numbers.
