TL;DR: The Blockchain Certification Advanced Training Bundle is on sale for £20.60 as of Feb. 25, saving you 96% on list price.

If you've taken note of any trends in finance, technology, and investing over the past 10 years, you've probably noticed the rise of cryptocurrency and blockchain technologies.

You may have even heard through the grapevine that blockchain is what powers cryptocurrencies like Bitcoin, Ethereum, Litecoin, and more — but what is blockchain actually, and how is it used?

You can learn all this and more with the Blockchain Certification Bundle, a set of online courses that are bundled together for just £20.60).

Blockchain is, at the most basic level, digital information (the "blocks") stored in a public database (the "chain"). The blocks store three key pieces of information:

How these blockchains function together is also what makes cryptocurrency appealing — because in order for a block to be added to the chain, four things need to happen:

Once that block is added to the chain, it's publicly available to view — making blockchain technology and cryptocurrency an open, decentralised database of many, many transactions. This public register of data sounds complicated, but performs a simple function: It allows people to send money to one another, without the use of a bank, credit card company, or other fintech company like PayPal.

Blockchain technology data is shared and operates like a constantly updated, live registry of who owns what — as opposed to a company, private interest group, or even government entity that's controlled by a single person. That makes blockchain the ultimate democratic currency of sorts, consisting of a series of trusted transactions between two or more parties, verified by collaboration, and powered by the collective's best interests (a currency for the people, by the people). So unlike banks, corporations, or government entities, which can all have high barriers to entry, anyone can get into the cryptocurrency investment game.

Plus, unlike currencies and forms of exchange, it's terribly difficult to dupe cryptocurrency or commit fraud with it. New blocks in the chain are always stored chronologically and linearly, and once the block is added, you can't go back and alter the block — if you do so, you alter the "hash." So in the case, a hacker would want to go and change a single block, they'd also have to alter every single block that came before it on the chain — which would take a massive and improbable amount of computing power.

While blockchain is certainly used for currency, it's also used for many other things:

Blockchain provides a strong, secure system of management, with a stored, clear-cut record, and multiple "witnesses"/users that can verify facts. The opportunities to take advantage of this technology are nearly endless: you can use it to exchange money faster than ever, lower the barrier to financial wealth for all, develop secure databases through advanced cryptography, create reliable automated communication, and so much more.

In short, blockchain technology is the future — and we're only beginning to harness its potential. This Blockchain Master Class Certification Bundle is the perfect way to get started learning more about how blockchain is used, and how you can start to innovate with it. You'll gain a detailed understanding of blockchain basics — including the origins, objectives, and challenges — plus learn to decipher trends behind blockchain, Bitcoin, and cryptocurrencies. The bundle also takes you through a deep dive into Bitcoins, Hyperledger, Ethereum, and multiple blockchain platforms.

Usually, the Blockchain Master Class Certification Bundle is £638, but you can get it on sale for £20.60.
