Technical Skills Required for Blockchain Developer. You need a good set of technical skills to become a blockchain developer. Let’s discuss them below.

Blockchain Architecture Overview

Starting with blockchain architecture, you should have a complete understanding of how it works. In addition to that, you should understand important terms such as

Consensus (C)

An algorithm that ensures that all peers of the Blockchain network reach an agreement about the state of the distributed ledger is called a consensus algorithm.

Hash functions (HF)

Using a cryptographic hash function, a fixed-length character string is generated from data records of any length. Each data record can be a word, a sentence, a longer text, or an entire file.

When input data (keys) is randomly selected, a hash function transforms them into a string of bytes with a specific length and structure (hash value).

Cryptographic hash functions serve as the backbone of cryptographic security

Blockchain transactions can easily be identified through their hashes

Distributed ledger technology (DLT)

It is the technology infrastructure and protocols that allow simultaneous access, validation, and updating of records in an immutable way across a network that spans multiple entities or locations and is known as Distributed Ledger Technology (DLT).
