What is Crypto

A cryptocurrency or crypto asset is a digital medium of exchange that uses strong cryptography to protect transactions, control the creation of additional units, and verify the transfer of assets using blockchain technologies. Cryptocurrencies are an alternative currency to fiat. There is controversy as to the fact that cryptocurrencies have to be decentrally controlled or currencies centralized by central banks or another entity, leaving these entities and/or central banks without any function. It could be widely adopted and turned into a fiat currency for the entire planet.

What Role does Cryptos Have?

Cryptocurrencies serve as an exchange of value, meaning they share the same principle as fiat currencies. But it could be said that they are a version 2.0 since they bring novelties, one of them is not having a bank or central entity that issues them, nor geographical limits.

History (Cryptocurrency)

Cryptocurrency – History

In 1983, American Cryptographer David Chaum conceived an electronic money cryptographic system called eCash. Later, in 1995, he implemented DigiCash, which used encryption to make money transactions anonymous, albeit with centralized issuance and settlement (payment). This system required software to withdraw money from a bank and assign specific encryption keys before they could be sent to a recipient. This meant that digital currency could not be tracked by the issuing bank, government, or third parties. In 1996, the NSA published an investigation titled How to Make a Mint: Encryption of Anonymous Electronic Money. This investigation describes a cryptocurrency system, published on an MIT mailing list. Later, in 1997, published in The American Law Review. The concept of the cryptocurrency idea was first executed by Wei Dai, in 1998, proposing the idea of creating a new type of decentralized money that uses cryptography as a control measure, 15 minutes from the first cryptocurrency that was created was Bitcoin, created in 2009 by the pseudonym developer Satoshi Nakamoto, who uses the set of cryptographic functions SHA-2 (exactly the SHA-256) as his PoW (working tool) scheme. (an attempt to decentralize the DNS domain name system, which would make internet censorship very difficult), Litecoin (which would use the script as a PoW scheme, as well as, to have a faster transaction confirmation), Peercoin ( It uses a hybrid PoW / PoS scheme [working policy/participation policy], in addition to having an inflation rate of around 1%) and Freicoin (which is how Silvio Gesell’s concept was implemented by aggregating d epreciación en el Tiempo). Many other crypto money has been created, although not all have been successful, in particular those that have not provided any innovation.

Cryptocurrency – Features

In cryptocurrency systems, the protection, integrity, and balance of your account statements (accounting) are secure by suggests that of a structured network of agents (segmented file transfer or multi-source file transfer) that verify (distrust) one another referred to as miners, UN agency area unit principally general public and actively defend the network (the fabric) by maintaining a high process rate of algorithms, to own the chance to receive any low tip, that is distributed haphazardly. Breaking the existing security in a cryptocurrency is mathematically possible, but the cost to do so would be unaffordably high. For example, an attacker attempting to break Bitcoin’s proof-of-work system would need more computational power than the entire network (swarm) of all the miners in the system, and even then, would only have a 50% chance of success. 50% (Authentication Round #), in other words, breaking Bitcoin’s security would require more capacity than tech companies the size of Google. Quantum computing is expected to become a reality in the future, which would break the balance if developers were unable to implement the system in time to use post-quantum algorithms.
Cryptocurrencies make possible the so-called Internet of Value, also known by the acronym IoV ( Internet of Value ), also called the Internet of Money: they are Internet applications that allow the exchange of value in the form of cryptocurrencies. This value can be contracted, intellectual property, shares, or any property of something with value. Things of value could already be exchanged before using payment systems such as Paypal. However, the difference between paying with something like PayPal and Paying with a Cryptocurrency is that paying with PayPal requires payment to be made through private networks such as credit cards and banks, while payment using cryptocurrencies does not have to be. intermediaries. It goes directly from the buyer to the seller. In this way, there is a universal value transfer system, free of intermediaries. This system:
  • It reduces the cost of the transaction since there is no intermediation.
  • Reduce times. Although net payments are quick, settlements between the parties take time, and also the vendor receives the quantity days once payment. With cryptocurrencies, the delay is on the order of minutes.
  • It eliminates the need to use financial agents to carry out transactions.

Also among them, several advanced exchanges stand out that allow us to register, place the information and start making transactions. This highly benefits users who trade cryptocurrencies.

Architecture (Crypto)

The decentralized child cryptocurrencies are collectively produced system-wide, a publicly known radio that is specified when this system is created.

In central banks and traditional economic systems, governments control the amount of money on the market (for example, printing money or requiring book entries).

In the case of decentralized cryptocurrencies, companies or governments cannot intervene in the production of new units. Cryptocurrencies have an asset that supports their value, unlike traditional currencies. The current system is based on the individual or group known as Satoshi Nakamoto.

As of July 2020, there were around 5,790 cryptocurrencies according to CoinMarketCap. In a blockchain system, the integrity, security, and balance of the accounts are maintained by a community known as the miners. This community uses their computers or other specialized hardware to validate and close transactions, adding them to a collective database.

Much crypto money aims to gradually reduce the production of units, imposing a limit on the total number of units that can be made in circulation. Compared to traditional currency systems, crypto monies are more difficult to read due to the cryptography used in the system.

Cryptocurrency – Blockchain

The validity of each of the units is in the blockchain. A blockchain is an ever-growing list of records, called blocks, that are linked and secured using cryptography. Each block contains a hash pointer that links to a previous block, a date, and group action knowledge. By design, blockchains area unit inherently proof against knowledge modification. The blockchain is an “open, public, distributed ledger that records all transactions between two users in a permanent and verifiable way.” The blockchain is usually managed by a collective peer-to-peer network with a common protocol for adding and validating new blocks. Once registered, the data in any one block cannot be changed without altering all subsequent blocks. Blockchains are secure by design and are an example of a distributed system with high Byzantine fault tolerance. Decentralized consensus has been achieved thanks to the blockchain. Blockchains solve the double-spending problem without the need for a certificate authority or central server, assuming the 51% attack (which has worked with several cryptocurrencies) is not going to happen.

How does cryptocurrency work

Cryptocurrencies use various dating systems to “prove” the validity of transactions added to the blockchain without the need for an authorized third party. The first invention was the proof-of-work system. The most widely used systems are based on the SHA-256 algorithm and script. Other algorithms that have been used include CryptoNight, Blake, SHA-3, and X11. Another system, proof of stake, is a method that secures the network through distributed consensus by asking users to own a small portion of units. It differs from the proof-of-work system in that they don’t have to run very complicated hashing algorithms to validate transactions. The system changes a lot depending on the currency and there is currently no standard. Some cryptocurrencies use a combined system between the two.

Cryptocurrency – Mined

In cryptocurrency networks, mining may be a validation of transactions. For this effort, miners get units as an award. This reward lowers fees, creating a complementary incentive to contribute to the processing power of the network. The generation rate of new hashes that validate transactions has increased thanks to the use of specialized machines such as FPGAs and ASICs. This race to build cheaper and more efficient machines has been around since the days of the first cryptocurrency, bitcoin, which was introduced in 2009. Due to the increasing number of miners in cryptocurrency networks, the complexity of generating hashes has increased. over the years, causing miners to invest large amounts of money in specialized machines. Sometimes, the value of the rewards obtained did not justify the investment in machines, their cooling, and the energy consumed to make them work. Some mining pools share their processing capacity on the network to distribute the reward equally, according to the amount of work they have contributed for the probability of finding a block. In February 2018, the Chinese government stopped trading in cryptocurrencies, banning mining. Some miners have moved to Canada. Some companies are using data centers for mining near Canadian gas stations, due to low prices. In June 2018, Hydro Quebec proposed to the regional government to supply 500MW of power to mining companies. According to a February 2018 news from Fortune, Iceland has become “heaven” for miners, in part because of very cheap electricity prices. Prices are stable because they are close to renewable energy generation plants, prompting more mining companies to consider moving their operations to Iceland. The local energy company says that mining is becoming so popular that the country will use more electricity for mining than for powering homes in 2018. In October 2018, Russia will become the host of one of the largest mining farms in the world, located in Siberia.

Cryptocurrency – Rates

Fees on cryptocurrencies mainly depend on the supply of computing capacity of the network at the moment and the user’s demand for a fast transaction. The user can choose a specific fee, while the miners process the transactions in decreasing order. You can simplify the process for the user by offering alternative priorities and determining how long each might take. In general, it is usual to look for cryptocurrency exchanges with lower fees. For Ethereum, fees are determined by computational complexity, network usage, and storage needs. In bitcoin, fees change depending on the size of the transaction and whether SegWit is used. In September 2018, the average fee was $0.017, while for bitcoin it was $0.55.

Cryptocurrency – Initial offer

Initial Coin Offerings (ICO) are a controversial means of raising funds for a cryptocurrency. Startups can use an ICO to avoid regulation. However, securities regulators in many jurisdictions, including the US and Canada, have indicated that if a coin or token is an “investment contract” (for example, beneath the Howey check, i.e., associate degree investment of cash with an affordable expectation of profit). Significantly in the business or management efforts of others), is a financial asset and is subject to securities regulation. In an associate ICO campaign, a share of the cryptocurrency (usually within the variety of “tokens”) is sold-out to early backers of the project in exchange for the medium of exchange or different cryptocurrencies. According to PricewaterhouseCoopers, four of the ten largest projected initial coin offerings have used Schweiz as a base, wherever they’re often registered as non-profit foundations. The Swiss administrative unit FINMAstated that it’d take a “balanced approach” to ICO comes and permit “legitimate innovators to navigate the restrictive landscape and so launch theirs comes in an exceeding manner per national laws that defend investors and also the integrity of the economic system. In response to numerous requests from industry representatives, an ICO legislative task force began issuing legal guidelines in 2018, which aim to remove uncertainty from cryptocurrency offerings and establish sustainable business practices.


The use of these cryptocurrencies in illegal activities, as well as the impossibility for governments to establish tax policies on operations carried out through this means, is a matter of controversy.
