It’s the first time the White House has formally weighed in on cryptos

Questions have been raised as to whether Bitcoin has become a multi-layered system. Well, the answer is yes. This article tries to describe the different layers on which bitcoin is located. It’s all yours!

Have you heard of those who call Bitcoin digital gold? Clearly, cryptocurrency is rapidly gaining popularity and acceptance in the cryptocurrency world. The value of the coin is expected to rise further. However, it is noted that the coin can win or lose 50% of its value overnight. This has led to speculation among investors, but the coin is still “digital gold”. And to the question of whether bitcoin is a multi-layered system, it is necessary to know that bitcoin exists in two main layers. These are mining and semantic layers.

Ore layer

This is the layer on which the coin is made. Along with bitcoins, ether is created in this layer. Once the coins are created, the reliable blocks of bitcoins are transferred to the ledger. Currency production is carried out here. It should be noted that the currency arises from transactions in bitcoin blocks. Blocks are known as transaction fees. Currency can be created from the network itself or you can say “from the air”. The main advantage of creating currency from the network is that it provides incentives to miners.

Semantic layer

It provides a very important platform. The semantic layer is the layer where bitcoins are used as a means of payment. It also provides a platform for using bitcoins as a storehouse of value. Layers seem very important, don’t they? Bitcoin currency holders sign trust transactions that indicate that bitcoins have begun to be transferred between nodes at the semantic level. Moving can also be done by creating smart contracts. Smart contracts transfer coins between different accounts.

Lightning network

You’ve probably never heard of lightning. This is the latest invention presented by the bitcoin community. This layer will be able to work on bitcoin. With this invention will come an application layer on top of bitcoin. It will be very exciting. The most interesting thing is that its value can also be used to pay. This will be possible by carrying its value among people. With the invention of the lightning network, bitcoin will become both a transport layer and an application level.

Today, the value of bitcoin is estimated at about $ 9 billion. It is also known that Bitcoin is a decentralized cryptocurrency. This means that it operates without the supervision of a bank or administrator. Bitcoin is undoubtedly conquering the world of crypto.

In addition, the technology used in the extraction of bitcoin is called blockchain technology. It works by allowing digital information to be disseminated, not by copying it. Cryptocurrencies are a really interesting topic, and in the near future bitcoins may overtake our major currencies.

As expected, we received a lot of questions from readers after the publication of Crypto TREND. In this issue, we will answer one of the most common.

What changes are coming in the cryptocurrency sector that could be game changers?

One of the biggest changes that will affect the world of cryptocurrency is the alternative block verification method called Proof of Stake (PoS). We will try to keep this explanation high enough, but it is important to have a conceptual understanding of what the difference is and why it is an important factor.

Keep in mind that the core technology with digital currencies is called blockchain, and most existing digital currencies use a validation protocol called Proof of Work (PoW).

You must rely on a third party, such as Visa, Interact, or a bank or check clearing house, to perform your transaction with traditional payment methods. These trusted entities are “centralized”, meaning they keep their own books, which keep track of the history of the transaction and the balance of each account. They will show you the transactions and you have to agree that it is right or start arguing. Only the parties to the operation see this.

With most Bitcoin and other digital currencies, books are “decentralized,” meaning that everyone on the network gets a copy, so no one should trust a third party, such as a bank, because anyone can check the information directly. This verification process is called “distributed consensus”.

PoW requires “work” to confirm a new operation to access the blockchain. With cryptocurrencies, this check is performed by “miners” who have to solve complex algorithmic problems. As algorithmic issues become more complex, these “miners” first and foremost need more expensive and powerful computers to solve problems. Minning computers often specialize in using ASIC chips (Application Specific Integrated Circuits), which are more efficient and faster at solving these difficult puzzles.

Here is the process:

• Transactions are collected in a “block”.
• Miners confirm the legitimacy of transactions within each block by solving a riddle of a hashing algorithm known as “proof of work problem”.
• The first miner to solve the bloc’s “proof of work problem” is rewarded with a small amount of cryptocurrency.
• Once approved, transactions are stored in a public blockchain throughout the network.
• As the number of operations and miners increases, so does the difficulty of solving hashing problems.

While PoW helps get blockchain and decentralized, unreliable digital currencies out of the way, it has some drawbacks, especially with the amount of electricity these miners try to solve as soon as “proof of work problems.” According to Digiconomist’s Bitcoin Energy Consumption Index, Bitcoin miners use more energy than 159 countries, including Ireland. As the price of each Bitcoin rises, more and more miners are trying to solve problems, consuming more energy.

All of this energy consumption has prompted many in the digital currency space to look for an alternative way to validate blocks just to validate transactions, and the leading candidate is a method called “Judicial Evidence” (PoS).

PoS is still an algorithm, and the goal is the same as in the proof of the case, but the process of achieving the goal is completely different. There are no miners with PoS, instead we have “validators”. PoS is based on the knowledge that all people who confirm trust and operations have skin in the game.

In this way, instead of using energy to solve PoW puzzles, a PoS validator is limited to approving the percentage of transactions that reflect its ownership share. For example, a validator with 3% of the existing Ether can theoretically validate only 3% of the blocks.

Your chances of solving a proof of work problem in PoW depend on how much computing power you have. With PoS, it depends on how much cryptocurrency you have. The higher your stake, the higher your chances of solving the block. Instead of winning cryptocurrencies, the winner receives a confirmation transaction fee.

Appraisers enter their shares by “closing” part of the stock marks. If they try to do something harmful to the network, such as creating an “invalid block”, their share or security deposit will be confiscated. If they do their job and do not break the network, but do not gain the right to approve the block, they will get their shares or deposits back.

If you understand the main difference between PoW and PoS, here’s what you need to know. Only those who plan to become a miner or validator should understand all the intricacies and subtleties of these two verification methods. The majority of the population wishing to own cryptocurrencies will receive them only through one exchange and will not participate in the actual drilling or approval of block transactions.

Most in the cryptographic sector believe that digital tokens need to switch to the PoS model for digital currencies to survive in the long run. At the time of writing, Ethereum is the second largest digital currency after Bitcoin, and their development team has been working on a PoS algorithm called Casper for the past several years. Preferring Ethereum over all other major cryptocurrencies, we are expected to see the introduction of Casper in 2018.

As we have seen in the past, major events such as the successful implementation of Casper could significantly increase the price of Ethereum. We will inform you in future issues of Crypto TREND.

In the first days of its launch in 2009, several thousand bitcoins were used to buy pizza. Since then, the cryptocurrency has fallen by about 70 percent in mid-2018 to $ 6,000 and then risen to $ 65,000 in April 2021, much to the chagrin of many cryptocurrency investors, traders, or just anyone else. missed the boat.

How it all started

Note that dissatisfaction with the current financial system has led to the development of digital currency. The development of this cryptocurrency is based on blockchain technology by Satoshi Nakamoto, a pseudonym probably used by a developer or a group of developers.

Despite numerous opinions predicting the death of the cryptocurrency, the performance of bitcoin has inspired many other digital currencies, especially in recent years. The success of the crowded financing brought about by the blockchain fever has undoubtedly attracted those who tried to deceive the public, and this has attracted the attention of regulators.

Beyond Bitcoin

Bitcoin has inspired the release of many other digital currencies, with more than 1,000 versions of digital coins or tokens currently available. Not all of them are the same, and their values, such as liquidity, vary greatly.

Coins, altcoins and tokens

Suffice it to say that at this point there are wonderful differences between coins, altcoins and tokens. Although altcoins such as Ethereum, litecoin, ripple, dogecoin, and dashes belong to the ‘main’ category of coins, they are mostly traded on cryptocurrency exchanges, meaning that altcoins or alternative coins generally describe something other than advanced bitcoin.

Coins serve as a storehouse of currency or value, while tokens offer active or utility use, such as a blockchain service to manage the supply chain to inspect and track wine products from winemakers to consumers.

It should be noted that low-value tokens or coins offer positive opportunities, but don’t expect similar meteoric increases like bitcoin. Simply put, lesser-known tokens are easy to buy, but hard to sell.

Before you start cryptocurrency, start by studying the value proposition and technological considerations, i.e. the commercial strategies outlined in the white paper that accompany each initial coin offer or ICO.

For those who are familiar with stocks and stocks, this is no different than an initial public offering or IPO. However, IPOs are issued by companies with tangible assets and business experience. All this is done in a regulated environment. An ICO, on the other hand, is based solely on an idea proposed on a white paper by a business – which is still active and has no assets – looking for funds to get started.

Uncontrolled, so buyers be careful

“The unknown cannot be regulated” probably concludes the situation with the digital currency. Regulators and regulations are still trying to catch the ever-evolving cryptocurrencies. The golden rule in the cryptocurrency space is “caveat emptor”, let the buyer be careful.

While some countries focus on blatant fraud, they are open to adopting policies that are accessible to cryptocurrencies and blockchain applications. However, there are regulators in other countries who are more interested in the disadvantages than the advantages of digital money. Regulators are generally aware of the need to strike a balance, and some are looking at existing securities laws to try to manage the many flavors of cryptocurrencies globally.

Digital wallets: The first step

Wallet is important to start cryptocurrency. Consider e-banking, but exclude the protection of the law in the case of virtual currency, so security is the first and last thought in the crypto space.

Wallets are digital. There are two types of purses.

• Hot wallets connected to the Internet, which put users at risk of breakage
• Cold purses that are not connected to the Internet and are considered safer.

In addition to the two main types of wallets, it should be noted that there are wallets for only one cryptocurrency, and others for multi-cryptocurrencies. There is also the opportunity to have a multi-signature wallet, to have a joint account with a bank.

The choice of wallet depends on the user’s choice, whether it is pure bitcoin or ethereum, because each coin has its own wallet or you can use a third-party wallet that contains security features.

Wallet notes

Cryptocurrency wallets have public and private keys with personal transaction records. The public key contains a reference to the cryptocurrency account or address, as opposed to the name required to receive the check payment.

The public key is accessible to all, but transactions are only verified during verification and verification based on a consensus mechanism applicable to each cryptocurrency.

The private key can be considered a PIN code widely used in e-finance transactions. It follows that the user should never disclose the private key to anyone and should not back up this information, which should be kept offline.

It makes sense to have minimal cryptocurrency in a hot wallet, and a larger amount should be in a cold wallet. Losing a private key is as good as losing your cryptocurrency! From strong passwords to malware and phishing awareness, the usual precautions for online financial transactions apply.

Wallet formats

There are different types of purses according to individual preferences.

• Wallets made by third parties and to be purchased. These devices work as a USB device, which is considered somewhat secure and can be connected only when the Internet is needed.
• For example, web-based wallets provided by cryptocurrency exchanges are considered hot wallets that put users at risk.
• Software-based wallets for desktops or mobile phones are mostly free and can be provided by coin issuers or third parties.
• Paper-based wallets can be printed in QR code format, containing relevant information about cryptocurrencies that are public and have private keys. They should be kept in a safe place for as long as required during cryptocurrency transactions, and copies should be prepared in the event of an accident, such as water damage or fading of print data over time.

Cryptocurrencies and markets

Cryptocurrencies are trading platforms for those interested in virtual currencies. Other options include websites for direct trading between buyers and sellers, as well as brokers that do not have a “market” price but are based on concessions between the parties to the transaction.

Thus, there are many cryptocurrency exchanges located in different countries, but with different security practices and infrastructure standards. They are those that allow anonymous registration, which requires only an email to open an account and start trading. However, there are others that require users to verify their international identity, known as Customer Identification, and to take anti-money laundering (AML) measures.

The choice of cryptocurrency depends on the user’s choice, but anonymous ones may have restrictions on the allowable range of trades or may be subject to sudden new rules in the country where the exchange resides. Minimal administrative procedures with anonymous registration allow users to trade faster and go through more KYC and AML processes.

All cryptocurrency trades must be properly processed and approved, which can take anywhere from a few minutes to several hours, depending on the coins or tokens traded and the volume of the trade. Scalability is known to be a problem with cryptocurrencies, and developers are working on ways to find a solution.

Cryptocurrency exchanges fall into two categories.

• Fiat-cryptocurrency Such exchanges provide direct transfers from banks or credit and debit cards, or the purchase of fiat-cryptocurrency through ATMs in some countries.
• Cryptocurrency only. There are only cryptocurrency exchanges that deal with cryptocurrency, meaning that customers must already have a cryptocurrency – for example, bitcoin or ethereum – to be “exchanged” for other coins or tokens at the market rate.

Fees are charged to facilitate the purchase and sale of cryptocurrencies. Users need to do research to be satisfied with infrastructure and security measures, as well as determine the fees they are comfortable with because different exchanges apply different tariffs.

Don’t wait for the total market price for the same cryptocurrency with different exchanges It may be advisable to spend time researching the best price for the coins and tokens you are interested in.

Online financial transactions are risky, and users should consider alerts such as two-factor authentication or 2-FA, keep up to date with the latest security measures, and be aware of phishing scams. One of the golden rules of phishing is not to click on the links provided, no matter how original the message or email.
