How Does Blockchain Work?

Cryptocurrency & Blockchains

What Is a ‘Blockchain’?

Blockchain is a distributed ledger or database shared among the computer network nodes. As a database, it stores information electronically and in a digital format. These blockchains are known for their essential role in cryptocurrency systems, like Bitcoin and Ethereum, for maintaining a decentralized and secure record of transactions. The innovation of a blockchain guarantees the security and fidelity of a data record, and it generates trust without requiring a trusted third party.

How Does Blockchain Technology Work?

A crypto blockchain is a combination of the following three technologies:

  • Cryptographic keys
  • A means of computing, as it stores records and transactions of the network
  • A peer-to-peer network that contains containing a shared ledger

Cryptography keys consist of Public and Private keys that help to ensure transactions between two parties are successful. Each individual has two keys, and they use them to create a secure digital identity reference. And this secured identity is a vital aspect of blockchain technology; this identity is called digital signature in the cryptocurrency world, and it authorizes and controls transactions.

People acting as authorities use this digital signature to reach a consensus on various transactions and other issues. Once they authorize a deal, a mathematical verification will certify it, resulting in a successful and secured transaction between the network-connected parties involved.

The data in that block cannot be altered or deleted unless all data within the blocks are changed before or after. Each block joins to the one before and after, which makes it secure because no person can modify or delete information in any of them unless they have access to them; each block has its private authentication key.

Each block has an identification number that links to the one before and after. The identification number repeats throughout the ledger to trace each transaction. The blockchain uses peer-to-peer technology, which means a person can send and receive money without using a third party, such as a bank or credit card company.

Once information is entered into a block, it stays there forever unless another block with greater force and more powerful computing power is entered later in the chain.

Many cryptocurrencies, including Bitcoin, originated from public blockchains, and they played a role in making DLT (Distributed Ledger Technology) popular. Additionally, public blockchains help to eliminate challenges and issues, including security flaws and centralization.

Blockchain has a great potential to revolutionize the way financial transactions are done. It’s secure, fast and safe. Companies operating in fields that require cryptocurrency will benefit from this technology because it will give them more transparency when dealing with clients. Blockchains offer security, as they can secure and protect sensitive data from online transactions. If you are looking for convenient and speedy transactions, blockchain technology is the ideal option.

What Is Market Cap?

Market cap in cryptocurrency refers to the combined worth of all the coins which have been mined. To get the market cap, you multiply all the coins in the market by the price of one coin. This metric indicates the market value and the specific size of crypto in the market. Market cap gives an estimate of how stable a cryptocurrency is. A cryptocurrency with a greater market cap will perform better in a volatile market.

To understand the market cap, you can think of it as how stable the cryptocurrency is. Bitcoin, which has the biggest market cap, experiences volatility, affecting each coin’s price. Cryptocurrencies with a larger market cap are considered stable investments, unlike those with lower market caps. Additionally, small market cryptocurrencies are prone to volatility in the market- they experience huge profits or dramatic losses.

It is important to note that you can measure market cap using either circulating or fully diluted supply. Circulating supply refers to the cryptocurrencies that have already been mined, while the fully diluted supply is the ones that have not yet been mined but finally will be mined. People measure the market cap differently using either a circulating supply or a fully diluted number.

The Importance Of Market Capitalisation

Market cap in cryptocurrency is essential because it serves as a tool for measuring the potential of specific crypto and its value against other cryptocurrencies. It helps to indicate the potential of a certain cryptocurrency, its growth potential, and if it’s safe to buy. Here is an example of how you can compare the value of different cryptocurrencies using a market cap.

If cryptocurrency A has 300,000 coins circulating in the market and each coin is valued at $1, its market cap is $300,000. Say cryptocurrency B has 50,000 coins in the market, and every coin is worth $3. Its market cap is $150,000.

Cryptocurrency B is worth more than cryptocurrency A. However, the value of cryptocurrency A is twice that of cryptocurrency B. It is important worth noting that the market cap for cryptocurrencies fluctuates because their market tends to be volatile.

What To Do With Market Cap

Understanding the market cap enables you to determine the value of cryptos, and you can make better investment decisions. Based on market cap, cryptocurrencies are divided into three groups:

Large-cap cryptocurrencies: Their market cap is over $10 billion and include Bitcoin and Ethereum. Large-cap cryptos are a low-risk investment since they show a positive track in their growth. Even when investors cash out higher volumes of large-cap cryptos, they can withstand it because their prices will not be affected.

Mid-cap cryptocurrencies: These are cryptocurrencies in the range of $1 to $ billion. These cryptos have greater potential for making profits but have a high risk.

Small-cap cryptocurrencies: They have a lower market cap below $1 billion and are prone to volatility in the market.


Market cap is an important tool for measuring and comparing the value of cryptocurrencies. When you fully understand the market cap in crypto, it will help you know the risks when investing, considering how the crypto market is volatile. When investing in cryptocurrencies, consider market trends, your financial situation, and a crypto’s stability will determine your investment risks.

What Is An NFT?

NFT is the new anthem in town; everyone is obsessed with this fantastic digital object. NFT is growing very fast, showing no signs of stopping soon. NFTs and Alex gierczyk seem to have similar motives. They push human limits and technological advancement through explicit knowledge and systems optimization. In this post, you will read the meaning of NFTs and why people are investing in them heavily.

NFTs Definition

NFT is an abbreviation for non-fungible tokens. The term fungible refers to assets that share the same attributes and can be traded interchangeably. A good example is bitcoins, they are fungible as it allows users to trade one with another, and the asset will not change.

So what are NFTs? It is a special kind of cryptocurrency developed on smart contract platforms, for example, Solana, Ethereum, and Avalanche. NFTs are digital objects that anyone wants to own because of their uniqueness. They can make a lot of profits, primarily when traded.

As stated earlier, NFTs are non-fungible tokens, meaning that every token is different in its own way, and replication is not possible no matter what may be tried. Due to this rare characteristic, they are represented in the form of unique information on the blockchain. Such attributes promote the integrity of digital possession. The existence of the NTFs’s always stamped upon their arrival on the blockchain, making it hard to change the original ownership.

Reasons Why People Are Investing In NFTs


The rareness of this commodity is one of the many reasons it has been attracting investors. Investors always look for something that will offer a unique experience; when it comes to forgery, it cannot happen on NFTs. Since they cannot be forged, they are unique in the market that is why their value tends to increase. Most often, sellers or artists tend to have a small quantity of these precious digital objects. Therefore the collectibles stand a good chance of retaining their worth, which is what every investor is looking for tirelessly.

Resell Ability

People are joining the NFT movement to make a considerable profit. That is why you will be many people investing in the NFTs so that they can be able to resell them and earn huge cash. NFTs are a rare commodity, they are unique, and it is hard to forge them. Therefore whenever an individual invests well, nothing will stand between them and the big sums of profits. The resell ability makes it simple to the wise investors who know where to invest, as a big reward awaits them.


To many investors, before they decide to put their money on something, security is among the factors that they seriously check for. They need assurance that their money will be safe, and the only way to convince them is by elaborating on the security. In NFTs, investors are guaranteed the complete security of their investment. If you look at how the blockchain market operates, you will not be mentally disturbed about data loss.

Decentralized Marketplace

NFT can be termed an unconventional investment, but luckily it has a decentralized market. It gives the creators a chance to make money straight from their work. Creators will not meet with intermediaries. We all know the dramas behind intermediaries; no investor would wish to encounter them. NFT has none of them; with this, many investors have been joining the camp. Since there are no middlemen, the original creators can enjoy the commissions themselves whenever NFT makes an exchange.


To anyone who is looking for an investment opportunity, NFTs offer the right platform that you will enjoy the experience. They are unique and fresh in the market; therefore, there is a higher chance of you earning more if you invest wisely. Many people are after these unique digital collectibles; why? Because security is guaranteed, uniqueness and resell ability are among many factors.

Will Ethereum Become the New Bitcoin?

After Bitcoin, Ethereum (ETH) is the second most popular cryptocurrency in the crypto world. Ethereum was founded in 2015 by Vitalik Buterin and Gavin Wood, and its market value now accounts for more than 17% of the $1.2 trillion global crypto market.

There are several critical distinctions between Ethereum and the original cryptocurrency. In contrast to Bitcoin (BTC), Ethereum is designed to be much more than a means of trade or a store of wealth.

The Rise of Ethereum

The blockchain underlying the second-largest crypto, Ether, will eventually undergo a widely awaited update, which may result in more institutional investors investing money into the network and helping Ether’s price rise.

The objective is to make Ethereum, the blockchain, more scalable, safe and long-lasting. Among other things, the update would render crypto mining obsolete, decreasing the massive amount of energy necessary to generate new tokens—a subject of intense criticism.

At approximately $804 billion in market value, Bitcoin is now the most valuable cryptocurrency. However, Ether, with a current market valuation of more than $360 billion, has the potential to become the top after the infrastructure update known as the “merge.”

Observers in the sector believe the “merge” will occur over the summer. Investors are already betting on it, and a lot of money is at risk.

Ethereum vs. Bitcoin: Similarities

No governing body regulates Bitcoin or Ethereum. Instead, they function on the premise of a peer-to-peer network. Both systems use a public ledger protected cryptographically to verify and store the transactions on the web.

Since peers must reach a consensus on transactions’ sequences and outcomes, it is challenging to commit fraud or tamper with the ledger. Therefore, Bitcoin and Ethereum are very safe cryptographic technologies due to both systems’ built-in cryptography.

Users of Ethereum and Bitcoin can access their cryptocurrency tokens from inside a safe and reliable digital wallet.

Both Ethereum and Bitcoin have seen a meteoric price surge, raising the issue of whether cryptocurrency would be a better investment in terms of long-term capital appreciation.

The Proof-of-Work (PoW) paradigm stipulates that Bitcoin or Ethereum will be distributed consistently as rewards to peers on the network that process transactions (miners). As forms of virtual money, Bitcoins (BTC) and Ether (ETH) are both capable of being bought, sold, traded, and even swapped for products.

Ethereum vs. Bitcoin: Key Differences

The key distinction between Bitcoin and Ethereum is in the applications each one is best suited for. Bitcoin was developed exclusively to serve as a digital currency and a store of value, analogous to the traditional currencies used today. Bitcoin believers have high hopes that the digital currency will one day be widely recognised worldwide, allowing users to purchase things, trade Bitcoin for other currencies and many more.

On the other hand, Ethereum has a far more far-reaching impact on the landscape of blockchain technology. In addition to its usage as a cryptocurrency, like Bitcoin, ETH has other applications, such as developing quicker and more secure business apps. One can use these applications in a range of markets. The Ethereum open-source community is also actively fixing bugs, adding new features and refining existing ones.

Also, unlike Bitcoin transactions that take minutes, transactions using Ether are completed in seconds, making them much quicker. In addition, Ether transactions use several encryption methods while Bitcoin only utilises the SHA-256 hashing algorithm.

Mining Bitcoin and Ethereum may look quite different soon, despite the processes being the same. The Ethereum network is moving toward a concept called proof-of-stake, the goal of which is to prevent a small number of entities from controlling the mining of Ethereum to make a profit. Individuals who do not have specialist equipment will have a more significant opportunity to profit from mining depending on the quantity of Ethereum they own if they stake it on the blockchain. Thanks to the proof-of-stake paradigm, this is now possible.

In terms of how widely Bitcoin has been used as a payment method, it is well ahead of any other payment system. Additionally, Bitcoin has a market valuation that is more than twice as high as Ethereum. However, Ethereum is by far the most similar cryptocurrency to Bitcoin. However, since one can use it in various contexts, Ethereum is now the blockchain with the most users worldwide.

Although Ethereum’s developer has floated the possibility of imposing a supply cap, the cryptocurrency does not have one today.

Will Cryptocurrency Ever Become A Mainstream Currency?


There has been plenty of talk surrounding cryptocurrency recently. The buzz of this ever-evolving industry has not been like so since its inception in 2008. The pioneer cryptocurrency, Bitcoin, is the leading token and face of the industry. It has developed in several ways to assure that indeed cryptocurrency will become a mainstream currency sooner than expected. Everyone knows of the crypto miner who traded 10,000 bitcoins for two pizzas in May 2010. In the current market, these bitcoins are worth nearly USD 400 million. The unpredictability of value makes it a highly volatile investment. It still has gained its way into the mainstream.

Bitstamp’s Survey On Crypto As A Mainstream Currency

A crypto exchange service surveyed the possibility of cryptocurrency becoming a mainstream currency. In its findings, crypto will adopt into the mainstream within ten years. Bitstamp exchange conducted the survey. It involved over 28, 000 investors from 23 countries. These countries were widespread from Europe, North America, the Middle East, Latin America, and Asia-Specific. From this, 88% of the institutional investors and 75% of the retail investors foresee crypto having mainstream adoption within ten years. Furthermore, 80% of the institutional investors believe it will surpass the custom investment vehicles. The level of trust in crypto is high. 71% of investment professionals and 65% of daily investors have their trust in digital assets. Developing countries portray most of this trust. 79% of emerging economies believe crypto is more trustworthy compared to the 62% of more developed financial markets.

Signs of acceptance of crypto into a mainstream currency

PayPal has embraced crypto into its platform. Users can transfer digital currencies amongst each other, and recently, the platform enabled users to withdraw. PayPal has an expansive market reach to ease the trading of crypto. Household names in the investment space are also getting into the crypto space. 

There is growth in the crypto ecosystem via the Ethereum network. Smart contracts enable Dapps for P2P crypto exchanges and lending. The Ethereum 2.0 will enable access to financial services without fiat currency.

Importance Of Regulation In Making Crypto A Mainstream Currency

Cryptocurrencies have grown popular due to their decentralized nature. The currency is not issued by a Central Bank or regulated by the government. They have the free will to develop without regulatory supervision. It has been the key to its innovation and anonymous users that increased its usage. However, there is legitimate concern over the decentralized nature of crypto if it were to become mainstream. The elements of decentralization have exposed the crypto industry to scams, speculation, and market manipulation. Investors may not have as much protection over their assets. As portrayed by the Bitstamp survey, the key barrier to crypto investing is confidence and trust in its regulation. Regulations are critical for the cryptocurrency’s long-term success. It ascertains investor confidence, market stability, and a safe ecosystem.

Several governments are proposing regulation measures for the industry. The EU parliament voted for new traceability rules for crypto providers. They are to collect information on the users of their platforms and exchanges who hold crypto. It was met with concerns by crypto users regarding the privacy that is associated with crypto. It shows that what the regulations should entail is still up for debate.

Uncertainty over the content of regulation is causing a lack of international cooperation. Each country is likely to provide its own regulations. Central banks of countries are also considering their own digital currency(CBDCs). It should assist in monetary policy changes and improve global financial health. The adoption of CBDCs ensures a decreased cost of transfer of fiat currencies between banks, consumers, and companies. An international monetary policy on these digital currencies will have more progress for global commerce.

Banks must develop financial instruments around crypto. JP Morgan is developing a structure around this by investing in the blockchain. It is developing digital coins and having investments in the metaverse.


Crypto is a viable medium of exchange that is penetrating the mainstream. Increased adoption is critical in reducing its volatility. There will inevitably be increased adoption. Those that position themselves will benefit from crypto as a mainstream currency.

A Beginners Guide To Cryptocurrency

What Is Cryptocurrency?

Cryptocurrency is a decentralized currency which is a digital asset. In crypto, all transactions are highly encoded. It is where its name originates. The encryption makes the transactions secure. The main difference between hard currencies and crypto is that crypto is not controlled by a central body or authority while hard currency is. Cryptocurrency is equated to valuable metals like gold and silver. Something else to note is that crypto is limited in number. Powerful computers crack difficulties. It is the process used to create cryptocurrency through mining. The powerful computers make transactions which are beneficial to the crypto market. After every transaction, a new cryptocurrency is introduced into the crypto market.

Most cryptocurrencies control and record their transactions through blockchain. It is crucial since it enhances the security of your investment. It happens as a result of duplicate transactions among numerous entities. Blockchain technology has made crypto transactions secure. More investors should take into consideration investing in cryptocurrency.

The Growing Crypto Market

Today the crypto market is estimated to be worth more than $1 trillion. There are thousands of cryptocurrencies. The number is to increase. The largest cryptocurrency in relation to market capitalization is Bitcoin. Bitcoin is followed by Ethereum and Tether. In many countries, now cryptocurrencies are accepted. More countries are to accept cryptocurrency. Some retailers in the US have for some time been accepting Bitcoin as a means of payment. 

Even well-established corporations worldwide are purchasing Bitcoin and other digital currencies. Bitcoin came to the surface in 2008 when there was an economic and financial crisis. It was the first cryptocurrency. As the years went by Bitcoin received numerous recommendations from well-established brands like Forbes. That is how it became an attractive asset. Crypto markets are becoming more transparent by the day.

What Economic Impact Has Cryptocurrency Had?

With cryptocurrency being well established today, the economic impacts are visible in international and national markets. The economic impacts are increasing as experts have predicted that in the future, billions will be unlocked and invested in cryptocurrency. The use of blockchain technology is a game-changer. Cryptocurrency is a digital asset which retains its value. It cannot depreciate or lose value as compared to world currencies. Blockchain has improved business practices in numerous ways.
