cryptocurrency and blockchain Tutorials

Blockchain technology and cryptocurrencies are one of the hottest technology trends in the past ten years. The concepts that underpin it are still confusing to many, but they will have an enormous impact on our lives. 

The blockchain is a revolutionary concept that has the potential to impact nearly every field just like the internet has driven every field in the past 2 decades. Instead of having our financial systems and technology platforms centralized through one group, it looks increasingly likely that we will have more of a decentralized future. 

If you are interested in learning this new technology and getting a head start in this field, here’s a list of the top 10 cryptocurrency and blockchain tutorials.

What is a Blockchain?

Everybody’s heard about the blockchain at this point, and it’s one of those buzzwords that companies love to throw around, like Artificial Intelligence and Big Data. But like the latter two, there is actually some weight to what they represent, and they have the potential to change how we interact with each other at a deep level.

The idea of a blockchain is actually quite simple: it is a distributed ledger. A ledger is simply a store of data, whatever that data or use case may be. Its most characteristic quality is the fact that it is decentralized, i.e, there is no single entity that decides what information is right and wrong. 

Take a bank for example, whose main purpose is to ensure that all the money coming in and going out is tallied up correctly. The bank is a centralized entity that ensures that financial data recorded in its ledger is accurate. You can trust the bank to ensure that your account is credited when you receive a deposit, and the sender’s account is debited when they send funds.

However, there are downsides to centralized systems, and these can broadly be categorized into security, cost and speed. These issues arise from the fact that there is one central authority who handles all the transaction recording, and they can be subject to server downtimes, are susceptible to fraud and charge higher for transactions, especially international ones. 

This is where decentralized ledgers show their worth. Bitcoin and other blockchains remove the intermediary and the transaction recording is conducted in a way that every node on the network is incentivized to correctly record information. As such, with a distributed network, security is higher, the costs are lower and the transaction confirmations are faster.

How Do Blockchains Work?

So, knowing what those advantages are, how exactly does blockchain work? We’ll take Bitcoin as our blockchain example.

A blockchain contains a series of blocks that contain transaction information. It is a shared public ledger. This is where the transaction and recipient addresses are stored, as well as the ledger information that tallies the amount of bitcoin sent and received. Bear in mind that this information could be anything, not just finance-related data. 

If you want, you could download the bitcoin blockchain yourself, though it is quite large. You can view all of the transactions that have taken place on the blockchain. Alternatively, you can visit one of the many bitcoin blockchain explorers online. 

Users have what is known as a public address, which you can think of as a bank account. They have private keys - which must be stored safely - that can be used to access their address and the stored funds. Funds are sent and received through these public addresses.

Transactions are verified and added to the blockchain through a process known as mining, which takes place in a Proof-of-Work network, which bitcoin is. They are rewarded for doing so, and this is where Satoshi Nakamoto’s brilliance is most clear. These different entities work to agree on the state of the blockchain, preserving chronology and authenticity. It is worth noting that the rewards for bitcoin mining reduce with time, as the difficulty of complex mathematics required to mine blocks becomes harder. 

That is the long and short of it. The full explanation is much more technically complex, but this is a good primer for how bitcoin and blockchain works. There are many types of consensus beyond Proof-of-Work, and those blockchains operate differently. If you’re interested, do your own research on them.

What is the Best Way to Learn Blockchain Technology?

The best way to learn blockchain technology is by getting your hands dirty. You should make good use of a blockchain tutorial, of course, but that must be secondary to actually build a blockchain. Take your theoretical learnings and implement them practically. 

Is Learning Blockchain Technology Hard?

Learning how to build a blockchain and all the associated concepts isn’t any harder than learning some other computer technology. There are some unique considerations, but it is fundamentally programming logic.  One example of blockchain technology is Ethereum, and it has good career prospects. 

How Long Does it Take to Learn Blockchain Technology?

For the most basic kind of blockchain, it doesn't take very long at all for you to get off the ground. This could be a matter of weeks to a few months. However, it is what follows that is challenging, as there is much more than just launching a blockchain. In fact, creating a basic blockchain can be done in just a day if you have a slight technical bent. 

But creating a minimum viable product, with adequate security and features is a much more challenging prospect, and may take a year or more. 

Is Bitcoin a Blockchain?

Yes, bitcoin is built upon a blockchain, and it launched the current market of blockchain-based applications. Bitcoin was built by an anonymous developer, or group of developers, called Satoshi Nakamoto. It uses the previously explained decentralized system to ensure that information on the blockchain is correct.
