What is Blockchain Technology? A Glossary For Beginners

The problem with writing about blockchain technology is that once you’ve explained something, it brings up a bunch of other terms and jargon that also need explaining; it’s a cruel cycle that we believe shouldn’t be anywhere near as complicated as it is.

In order to help explain what a blockchain is (blocksplaining as we like to call it) here is a short and sweet explanation of all the buzzwords, you’ll hear while researching or reading about the disruptive technology.

Cryptocurrencies: These are intangible, virtual currencies that are traded online across a number of different applications.

Coins: Types of cryptocurrencies, one of the first and most well known being Bitcoin.

Nodes: When you make a transaction with a cryptocurrency, a copy is stored as data on your computer; in a network, these computers are known as nodes.

Distributed Networks: When a transaction is completed its data is shared and stored between every node in a network, making it distributed, but if this data was distributed by one central node, it would be centralised.

Blocks: These are the data recorded from transactions, which are added to a chain after they have been processed.

Genesis Block: Simply the first block on a blockchain.

Mining: The process of building blocks, difficult computing calculations are made by a miner, and if they are successful, the miner is rewarded with coin and the block is added to the chain.

Mining Pool: A number of different miners contributing to mining a block.

Hashing: A simplified code storing all the data of previous blocks on a chain.

Merkle Tree: This is the structure of previous hashing data or hashes.

Smart Contracts: Self-executing agreements added to a blockchain as data.

ICO (Initial Coin Offering): Investors are offered an amount of a new cryptocurrency in exchange for the financial backing of existing ones.

Proof of Work: Miners in a network compete to be the first to solve computing calculations, with rewards (coins) being given to the first person to do so.

Proof of Stake: Miners are decided upon by the amount of wealth they own, and can be backed by other users who fund their mining solution.

Bitcoin: One of the first and most well-known cryptocurrencies, and although it is extremely popular for its network and security, it has a few flaws such as scalability.

Litecoin: Very similar to Bitcoin, Litecoin uses a different hashing method in order to make mining more possible for less powerful computing systems.

Ether: Ethereums coin, focused on the technical side of blockchain development. Including things like smart contracts and decentralised applications.

Ripple: Ripple is more concerned with transactional utility, acting as a global settlement network for a large number of different currencies.

Dash: An effort to improve on Bitcoin, this cryptocurrency stands out for its speed of transaction processing and anonymity.

Zcash: Offers selective transparency, privatising details like the sender, recipient and amount.

We don’t blame you if you don’t, there’s so much talk around the rabbit-hole that is blockchain; we’re finding different opinions and digital strategies everywhere on a technology that’s evolving on a daily basis.

CUBE has been exploring blockchain thoroughly over the last few months, presenting at IFC 2017 and planning ways we can implement the technology ourselves and on behalf of the clients we have the pleasure of collaborating with.
