What is cryptocurrency?

Candidate investors who are new to the cryptocurrency market or want to enter should first enlighten themselves on the question of what crypto is, so that they know what they are investing in. Cryptocurrency is a digital money that is not backed by physical assets like traditional money. Cryptocurrencies are created using a special data encryption technology (cryptography). And since it is protected against decryption and decryption, it has a high level of security. Yes, this is where the name of cryptocurrencies comes from, which came into use after the article “Cryptocurrency” was published in Forbes in 2011. Until this published article, bitcoin, for example, was called electronic cash.

Crypto is decentralized as it operates thanks to the computational work of many independent computers called nodes. The element of crypto that is an alternative to traditional finance concentrated in banks is decentralization. Also you can play on cryptocurrency starting with just 1 euro, the page with 1 euro casino bonus will help you.

Most cryptocurrencies are based on blockchain. Cryptocurrencies exist only in digital (virtual) form. As can be understood, the scope of virtual cryptocurrencies and other assets is different. Crypto performs the following functions:

• Investment tool. To generate passive income;
• Capital accumulation method;
• Means of payment. Paying for goods and services in the real and virtual world;

In other words, you can invest in cryptocurrencies to:

• Earning profits from changes in the value of an asset;
• Possessing crypto to earn income from any company or to vote on its decisions;
• Paying for items like a cup of coffee or an electric car with cryptocurrencies;
• Paying with digital currencies to get additional features in games and some online services.

For now, let’s continue to get to know cryptocurrencies, now that we have learned what crypto money means in detail.

Why do you need crypto?

The main idea of crypto is decentralization and independence. Bitcoin, the first cryptocurrency, emerged in response to the historic global economic crisis of 2007-2008. The main causes of the crisis were:

• Mortgage default crisis in the US;
• Banks that created the mortgage crisis and uncontrollably issued unreliable investment instruments;
• Government overlooking effective bank regulation.

Early crypto enthusiasts tried to invent an alternative financial system that would not be controlled by governments and banks. After the crisis, the purpose of crypto money became more understandable.

Blockchain technology enables Peer-to-Peer money transfers (direct, without intermediaries). Since cryptocurrencies operate on blockchains, there are no untrustworthy intermediaries that can be manipulated.

What is Blockchain?

Blockchain technology is a digital database running on software. Its original purpose is cryptography, or the encrypting of data in a blockchain with records. Blockchain is the main technology of cryptocurrencies. Every crypto transaction goes through the blockchain. Different cryptocurrencies may have different blockchains, but most cryptocurrencies run on the Ethereum network blockchain.

The most famous banking system is SWIFT. It confirms transactions and updates data in banks’ databases. Blockchain SWIFT provides includes both these features.

How does blockchain work?

Blockchain works like a distributed database. Data records are distributed over a network of independent servers. Each server is a computer called a node, controlled by the user of this network. The list of transactions is called a block. Many of these blocks work like a chain, which is why this technology is called blockchain.

Multiple blocks form a sequence of blocks, which becomes a chain. The data encrypted in each block is immutable, just like the previous blocks. This system makes the blockchain a relatively secure database, as fraudsters cannot access data without leaving a trace.

This means that all data is processed by special software, smart contracts (programs that are automatically executed when pre-agreed conditions are reached). When a question arises about the legitimacy of a particular transaction, the users with the most presence in such a network decide whether everything is okay with the transaction.

The staking system emerged to motivate users to own a large number of assets that keep the network running. Staking is the locking of assets in a separate smart contract for a certain period of time. As a reward, stakers receive profits in the form of predetermined percentages of the locked token amount.

Staking is like a bank deposit needed to ensure the operation (maintain liquidity) where the bank rewards the customer with a percentage of the deposit amount.

How do cryptocurrencies work?

Cryptocurrency operates on a decentralized Peer-to-Peer Network, meaning transactions occur directly between users without the need for a central authority or intermediary such as a bank.

When a user wants to make a transaction, they use a digital crypto wallet that stores cryptocurrency. The transaction is transmitted to the network and verified by other users. Once verified, it is added to the blockchain, which contains a public record of all transactions on the network. The transaction is then considered completed and ownership of the cryptocurrency passes from one user to another.

So what is Bitcoin?

Bitcoin is a cryptocurrency that runs on its own blockchain. Bitcoin is the first cryptocurrency and the most famous. Bitcoin’s Whitepaper (a document explaining the principle of the crypto project) was published by Satoshi Nakamoto in 2008. And in early 2009, the Bitcoin network was launched.

Satoshi Nakamoto is anonymous. There are different versions of the identity of the creator of Bitcoin, right down to the fact that a whole group of developers is hiding under this pseudonym.

How many different cryptocurrencies are there?

Cryptocurrency may seem complicated. There are coins, tokens, altcoins, NFTs and other unexplained words. We will discuss the features of all of them in our cryptocurrency classification section and learn which ones do what. Here are the crypto types:

Coin

A coin is a cryptocurrency with its own blockchain. Blockchain is a complex technology that developers have spent a lot of effort and time to create. Coins that have their own blockchain include: Bitcoin, Ethereum, XRP, Solana, Tezos, EOS and others.

For example, ETH coin has its own Ethereum blockchain and carries out all transactions within this network. Ethereum’s architecture allows users to use this blockchain for many purposes, from closing business contracts to voting in elections.

Thousands of decentralized applications (DApps) have been successfully launched based on the Ethereum blockchain. Therefore, many crypto companies are joining the Ethereum blockchain to create their own cryptocurrency or implement other ideas. Such projects include Uniswap, 1inch, Aave, MakerDAO, Sandbox, Chainlink and others.

Token

Many cryptocurrency developers use existing blockchains to launch cryptocurrency.

For example, a non-blockchain cryptocurrency made on Ethereum is a token. Token holders basically get the following benefits:

• Management within the community;
• Profit share in the project;
• Reduced transaction fees.

Tokens are divided into several types:

Security tokens are tokens that give ownership of a financial instrument such as a stock or bond.

Utility tokens are tokens that represent the greatest value in their network.

Asset-backed tokens are tokens whose value is confirmed by a real entity that is not on the blockchain. For example, gold or government currencies.

Stablecoin

Stablecoins are assets whose value is pegged to a commodity (like gold) or fiat currency. They exist as more stable cryptocurrencies with much less risk of price changes. The most popular stablecoins (Tether, USD Coin, Binance USD, DAI) are pegged to the US dollar.

Some stablecoins may experience a lack of liquidity, causing the price of such assets to begin to differ from fiat currencies or commodities.

Altcoin

An altcoin is any cryptocurrency other than bitcoin. Since Bitcoin is the first, most trusted, and largest in terms of usage (and therefore most used) cryptocurrency, any other cryptocurrency is considered a Bitcoin alternative. That’s why they are called alternative coins, or simply altcoins.

NFT

NFT (Non-Fungible Token) is a non-fungible token. Unlike other cryptocurrencies, NFT tokens are unique in their own way and cannot be replaced by others. Each asset has its own digital signature, making the NFT unique.

NFTs also operate on the blockchain. That’s why NFTs are usually made up of music, images, photos, text, etc. It is used to transfer works of art to digital media.

DeFi

DeFi (decentralized finance) consists of many decentralized applications (Dapps) that provide financial services. DeFi aims to be an alternative to traditional finance. DeFi provides an ecosystem powered by the automation of various protocols (e.g. smart contracts) that allow users to reject the services of intermediaries such as banks and payment systems.

Major DeFi services include:

• Lending;
• Loan of interest-bearing assets;
• Derivative trading;
• Changing.

DeFi uses cryptocurrency as a payment method for transactions between users.

There are currently the types of cryptocurrencies mentioned above in the market. Each of them offers different opportunities and services to users, but their main and common point is that they are investment tools.

Crypto: advantages and disadvantages

Cryptocurrencies have become very popular in recent years, and beginners, as always, are eager to find out what is problematic about this phenomenon market in the first place. Everyone is aware of the potentially high income that can be earned by trading cryptocurrencies. However, there are some cryptocurrency advantages and disadvantages that you should know before investing.

Advantages of cryptocurrency

Cryptocurrencies offer users unique opportunities not available for traditional financial and investment instruments.

Volatility

Volatility is the change in the price of an asset over a period of time. If in the stock market, an asset’s deviation from the daily norm by more than 10% is considered high volatility, then in crypto these indicators can reach several hundred percent.

The cryptocurrency world fundamentally has high volatility, which is often associated with a lack of liquidity, a rapid change in trend, or the flow of capital from one project to another. This means that the value of a cryptocurrency can rise significantly or fall sharply within days or even hours.

High volatility attracts investors who get a high-risk but high-reward trading option. Traders use different trading tools such as crypto futures and margin trading to gain more from sector volatility .

Speed

Crypto transactions are much faster than bank transactions. It takes little more than a few seconds for the cryptocurrency to process transactions. However, this period is much longer for bank transfers between countries and financial systems, which cannot leave the past behind.

Disadvantages of cryptocurrencies

Like everything in this world, cryptocurrencies have some disadvantages that you should be aware of.

Volatility

High volatility makes cryptocurrencies a very risky investment. With a reckless approach to crypto investments, if it is based entirely on luck or someone else’s opinion, you can quickly lose your savings.

Therefore, volatility is both an advantage and a disadvantage of crypto. Before investing, you need to be sure of your decision: follow competent risk management, do not invest the last remaining or borrowed funds, follow the news of the projects in which you invest, and also take into account many other market-related factors.

lack of regulation

The main idea of cryptocurrency is decentralization and independence from the government and its rules. At the same time, government regulations are not imposed for evil purposes and generally prevent fraud. For example, several cryptocurrency exchanges have recently gone bankrupt due to lax regulations, and some of them were outright scams. Blockchain technology is revolutionizing the online casino industry by introducing transparency, fairness, and security. With blockchain, every transaction and gameplay is recorded in a distributed ledger that cannot be falsified or altered, ensuring absolute transparency and fairness of the game. This not only increases player trust but also facilitates the fight against fraud and unfair play. Moreover, blockchain enables the creation of decentralized casinos where players can bet directly against each other, minimizing the role of the intermediary. Thus, blockchain not only raises the standards of security and fairness in the gambling industry but also opens new opportunities for innovative approaches in organizing the gameplay.

Cryptocurrency

Ranked tokens Bitcoin, Litecoin, Ethereum, Dogecoin and Tether allow for instant transfer of funds. The process of sending an asset between wallets does not involve banking institutions, so the parties remain anonymous. Blockchain smart contracts and tokens are directly linked, as cryptocurrency acts as an irreplaceable valuable resource.

Transaction functionality without intermediaries is appearing in online shops, markets and virtual goods sites. Online casino creators are also working to enable customers to deposit money in cryptocurrency. The list of supported tokens is expanding and this payment method is becoming available in the app, on a fixed or mobile version of the site. For more information on crypto casinos, visit the Casino Zonder website https://onlinecasinozonder.com/crypto-casinos/.

Financial products

Decentralised exchanges are built on blockchains that are accessible to every visitor and customer of the platform. Such resources are built on the principle of smart contracts, so the exchange is controlled by the audience when the administration remains idle. The customer connects a blockchain wallet, maintaining anonymity, and then trades on the platform with other participants. With a decentralised exchange, the user has the privilege of trading crypto without intermediaries, as well as conducting transactions without fees.

Platforms that use decentralised lending technology are emerging. This, again, opens up access to the content of the fragments for each visitor. Loan repayments are managed by smart contracts, so full automation of the process is achieved. No verification is required to receive a loan, but a designated number of tokens must be sent as collateral. Loans can be received in both cryptocurrency and fiat money.

Loans in blockchain gained traction when non-exchangeable tokens began to be offered as collateral. Since 2021, ideas and actual products are emerging so that users can provide NFT as collateral. However, the liquidity of these tokens as well as their uncertain value remains an issue. Tokenisation of NFTs is expected in order to determine their value and then use them as collateral.

Smart contracts

The blockchain smart contract is becoming an efficient technology for financial transactions between parties. The contracts are integrated into a decentralised network, and are created using Vyper, LL, Solidity programming languages.

Additional features of smart contracts:

• Conditions. The features of contract performance are marked programmatically, so they are used in an unmistakable way.
• Registry. Access to information on smart transactions is open to everyone.
• Execution. The written algorithm is executed as the blockchain checks the execution status of the contract.
• Anonymity. Smart contracts are distinguished by their degree of confidentiality: open, hidden, partially hidden.

The introduction of smart contracts has simplified financial operations and achieved full automation. Contracts do not require the involvement of an intermediary, which reduces transaction costs. In addition, smart contracts have eliminated the possibility of error due to the incompetence of one of the parties or the intermediary.

Financial audit

Customer due diligence or financial audits are conducted selectively. This is related to the model of crypto-institutions and the approach to lending. The originators intend to achieve mandatory credit scoring to confirm the stability of the potential borrower’s identity. Problems remain with the auditing of individuals, which affects the success of the partnership.

However, the field of decentralised blockchain-based platforms that lend to legal entities is growing. The collateral for the cooperation is the reputation of the brand, as well as publicly known data on the firm’s profitability and success. Companies that cannot get a loan from a bank prefer to use the services of such platforms.

Conclusion

Blockchain as a technology is improving and penetrating the financial services industry. Anonymity of transactions, security and confidentiality of information are seen as an advantage. Automated smart contracts are available, improving the interaction between buyer and seller.

Often, blockchains conclude contracts and use digital documents to guarantee fair and trustworthy partnerships.

1) Important technologies that preceded the emergence of the blockchain

Innovations preceding the blockchain

1. Peer-to-peer (P2P) is a peer-to-peer network in which multiple devices connect to share resources. For example, when one client downloads files, these files are immediately available for other users to download. The server queries the other systems for a list of active peers and adds some of them to its list. The first networks were developed and implemented in the 20th century for different purposes: APRANET (1969), its advantages: privacy, implementation and use of e-mail and USENET (1979) for communication and file sharing. Although P2P systems were previously used in applications, the introduction of Napster (for music sharing), developed by Sean Fanning, in 1999, popularized the technology.
2. PKI and PGP ciphers are tools for the secure exchange of data in electronic systems. Of course, there are differences: PGP is public-key encryption software for protecting data, while PKI is a public key infrastructure for internet security. It is exchanged by means of each user’s public and private key. To deliver information to a particular recipient, the sender receives the recipient’s public code and uses it to encrypt the information. The information can then be decrypted using the recipient’s private key. Both technologies provide a secure exchange of information and a strong authentication mechanism. A PKI can be used to create a system for accessing data on external media.
3. Proof-of-work is a fraud protection protocol (protection against DoS attacks, spam prevention, etc.). The idea is to complicate the process and make any manipulation unprofitable and prevent double spending in transactions. Without the validation mechanism (mining and hashing), the network and data would be insecure and easily stolen. A hash consists of 256 pseudo-random bits and often the owner of the chain makes up the code several times to match the rules, so it would be impossible for attackers to unravel the combination and compromise the data. The idea of POW was published by Cynthia Dworko and Moni Naor in 1933, and first used by Marcus Jacobson and Ari Jewels. The algorithm is used in digital currency.

2) Studies by Stuart Haber and W. Scott Stornett

In 1991, mathematicians began to think seriously about how to protect the information on various personal computers and avoid tampering with documents.

Scientists have experimented with storing documents on a cryptographically fixed blockchain and have tried to systematize these systems into blocks.

They used a previously patented design, the hash tree or Merkle, for their algorithm, which led to its enhancement and performance: increased security, transaction authentication and the systematization of multiple data into a single block. The researchers published their observations and research in “How to Record a Digital Document in Time” in the Journal of Cryptography.

As a result, the inventors became internationally renowned and the first digital currency, bitcoin, was developed based on research.

There is no definitive answer as to who created blockchain, as the creator of the hash tree concept is Professor Ralph Merkle, scientists Haber and Stornett introduced the innovations, and Satoshi Nakamoto added to the technology: limiting block size to 1 MB, which allowed quick transactions and work on gadgets.

3) Bitcoin

Blockchain was first used by developer Satoshi Nakamoto for financial transactions in 2008. Satoshi Nakamoto is a pseudonym for one person or group of people. The creators still remain anonymous.

Development began in 2007, and a year later released the first system powered by blockchain technology. Bitcoin is mined through mining – solving cryptographic problems. In simple terms, it is a ledger of funds where no funds can be obtained without access to the owner’s wallet.

In 2009, the technology went online.

Bitcoin was originally created for online transactions, but it has now become a digital asset in its own right, convertible into any digital currency (such as US dollars or euros).

4) Ethereum

Programmer Vitalik Buterin is the author of the cryptocurrency Ethereum.

The technology is being used not only for transactions, but also in asset-transfer transactions. For the first time, the creator of Ethereum began using smart contracts to enter into contracts. They are fully legal, as is the offline format. Electronic documents are encrypted and written in high-level programming languages.

Once the contract is signed and accepted by all parties, the contract enters into legal force. The information in the contract is available only to the parties to the transaction and is closed to third parties.

Not only is Ethereum a cryptocurrency, but it is also a decentralized platform (dAps), so many aspiring developers are using the technology to create their own digital currency.

Users will feel much safer

One of the key advantages of using blockchain technology in dating apps is the ability to considerably improve security and privacy. Blockchain technology is ideal to solve many security problems. It allows developers to create a decentralized platform and exclude the need for a central authority that would check transactions. Everything, including user data and communication between users, is encrypted, so no one can access this data without permission. Furthermore, all data is stored on the blockchain, making it rigid, secure, and closed. This way, the possibility of data breaches, hacking, or other forms of cyber attacks is minimized or even excluded.

Users can enjoy a better transparency

Blockchain technology also contributes to the transparency of dating apps. If blockchain technology is used in a dating app, app users can track their transactions, communication, and actions taken on the platform. This way, it gets easier to check the authenticity of the platform and its users. So users can spot and report any fraudulent activity or spam on the platform. In the end, the platform becomes way more secure for users. 

No fake profiles and scammers

Blockchain technology makes it easier for dating apps to verify the identity of users. It is achieved by storing a unique digital identity of every user on the blockchain, and then using it for verification. As a result, the dating app owner can promise users that the people they would interact with on the app are exactly those who they claim to be. And the fewer fake profiles there are, the more trust arises among all users. 

Decentralization

The use of blockchain technology allows for the creation of dating apps that can be owned and run by a community of users, rather than a central authority. Such practice leads to increased transparency and reduced censorship. In addition, the app gets less susceptible to attacks. 

Users indeed own their data

Blockchain technology lets users keep true control over their personal data. Users can require explicit permission to share or use their data. It can be particularly useful for dating app users if they can specify the types of data that they are ready to share with other users or the dating app. And what is even more useful is that a user can deny this permission at any time. As a result, you can be more relaxed that your personal data won’t be misused.

Users find better matches

Blockchain technology can even play its role in enhancing the accuracy of matching algorithms. Users who feel more sure about the security of their data are sharing it more willingly. As a result, the app has more accurate information and more parameters to match users. In addition, an algorithm based on a decentralized network is less susceptible to individual biases or preferences. What is more, a particular part of the blockchain family, smart contracts, helps ensure that users are matched with people who share similar interests and values and that both parties agree to the terms of the relationship.

Lower fees for more features

The use of blockchain technologies often leads to lower operating costs thanks to eliminating the need for intermediaries such as payment processors. So, such dating app providers are usually ready to give you more features for the same market price or similar services for a lower price. 

Conclusion

In short, blockchain technology can change the way we see the online dating industry. It has all the potential to ensure the level of security and transparency desired by users Thanks to blockchain, it is finally possible to get rid of all the fake profiles and protect user data to the maximum extent possible. 

Today, the usage of blockchain in dating apps is still in its early stages. However, some providers have already introduced it into their dating services and products, and we can expect to see more of it in the future. Blockchain seems a viable solution to the most common problems of online dating.
