This Thing Called Blockchain… [Beginners Guide]


Without a doubt, blockchain technology definitely brought a fresh intake of new ideas in various spheres of our lives. Apart from ideas, its solutions also have an aim to revolutionize not the just the global financial system but business conduction as well.

Thus, this review about blockchain to clear misunderstandings regarding its network, ledger records, innovativeness, and future outlook. For those interested in ICOs and purchase of cryptocurrencies, head over my other articles that cover these topics.

Disrupting technology

The main goal of blockchain technology is to provide a completely decentralized environment, where participants of the system create and maintain the network. The database is equally available to all individuals, regardless of their background and wealth.

Since its establishment in 2009, there have been a variety of blockchain systems up to date. Some systems allow mining and transfer confirmations, as a self-regulated approach to financial issues (bitcoins), while others offer smart contracts as a fail-free way to conduct instant business for low fees (Ethereum).

Innovation in Blockchain

Take Ethereum for example. Prior to the project in 2017, bitcoin lead the way with its mining confirmations, in which several miners needed to pick up transactions and confirm them through hash power. Ethereum introduced smart contracts, which were online agreements between two or more parties regarding transfers. The transfer would keep all agreed upon points, where value, timing, and content of agreement would be automatically carried out.

Next step was a lightning network, introduced by Joseph Poon and Thaddeus Dryja in 2015, which was developed as a solution to bitcoin’s scalability issues. It is placed on top of the blockchain’s network, where transactions would connect peers without confirmations, increasing the transfer speed and security. The whole system is based on microtransactions, where multiple parties can form without the use of blockchain’s transfer system and yet be kept in ledger records.

We now have many other systems that solve several issues, such as Ripple (banking system), Monero (fungibility and decentralization), Dash (nods instead of centralized supply), Cardano (decentralized development), and many others as well.

Application in Various Industries

Through smart contracts, for example, Ethereum and other projects aim to provide a safe ground where the middle party would not be needed. The cost of transferring value from one side to another would thus be lowered significantly, while transfer speed would surpass banking services by far.

Bitcoin and all other cryptos can be used as a medium for payment for goods and services. Thus, using crypto retail, pharmaceutical, and other industries would experience a decentralized yet unified marketplace, where participants from all over the world can purchase and sell their services without boundaries.

Scams and Hacks

Famous examples of such scams are Pincoin and iFan, both of which brought in $660 million worth of investments. Companies behind these projects promised lightning-fast transactions, secure transfer system, and privacy, only to take the money and disappear without a trace.

Hacking attempts in the past also proved the point that current blockchain networks needed better solutions in terms of safety. Bitfinex ($72 million) and Mt. Gox ($473 million) give out a warning sign that ledger records, although providing transparency, cannot stop the theft of assets, even if address codes are revealed.

Coins and Tokens

Some are minable and some are not, depending on the developer’s idea on how blockchain world should be organized. These cryptocurrencies can be evaluated through fiats or through services they provide for participants.

What About Mining?

There are two ways on how tokens would be distributed within the blockchain’s system. The first is through mining, which bitcoin, Ethereum, Litecoin and many others use. Individual participants would provide their computer’s hash rate and mine cryptocurrencies in order to be awarded blocks. Then, they would sell them out and earn profits from their operations while the market is supplied by the amount awarded by the blockchain.

Others, like Ripple, IOTA, and Cardano, monopolize the supply as to avoid rapid fluctuations in value. Developers keep the supply to either control the price as their blockchain systems are meant for purposes other than trading and mining. In these systems, participants would usually purchase coins in order to use them for online services.


Luckily, we have many exciting projects planned for in 2018 and 2019 and judging from the number of cryptos currently in the market, the blockchain networks are yet to show what they can really do.
