In a nutshell, blockchain is an ever-growing digital list of data records. Such a list contains many data blocks, arranged chronologically and connected and protected by cryptographic evidence.

The first blockchain prototype dates back to the early 1990s when computer scientist Stuart Haber and physicist W. Scott Stornetta used cryptographic techniques in a series of blocks as a way to protect digital texts from data interference. as the first electronic currency (or the first cryptocurrency). The white paper Bitcoin was published in 2008 under the pseudonym Satoshi Nakamoto.

As a widespread ledger (DLT) technology the blockchain is deliberately designed to be highly resistant to conversion and fraud (similar to duplication). This is true because the Bitcoin blockchain, as a record site, is unchanged, and cannot be disrupted without the impossible amount of electricity and integration power – meaning that the network can force the concept of “real” digital documents, making each one. Bitcoin is a very different and non-copy-able form of digital currency.

Cryptocurrency

Digital currency is protected by cryptography and, more commonly, is used as a means of exchange within a digital peer-to-peer (P2P) digital economic system. The use of cryptographic writing techniques is what ensures that these systems are completely free of fraud and corruption.

The first cryptocurrency ever created was Bitcoin, introduced by anonymous developer Satoshi Nakamoto, in 2009. Nakamoto’s goal was to create a new electronic payment system that would allow digital financial transactions to take place between users without the need for intermediaries, such as banks Government institutions.

Many cryptocurrency systems operate on a nationally distributed computerized network of distributed computers. Each computer (or device) that joins a network is called a node. In simple terms, a node is any visual device connected to a network and capable of sending, receiving, and transmitting the information. For example, the Bitcoin network is made up of, at least, seven different types of nodes, and the nodes performing all available functions are known as full nodes.

Trading

An exchange is a structured marketplace where financial instruments – such as cryptocurrencies, assets, and securities – are traded. The exchange may operate in a real-world environment or in a digital arena. Many traditional trades, which were initially restricted to physical trading, now provide digital services as a way to enable electronic trading (also known as paperless trading).

One of the main functions of the exchange is to provide funds within a secure and orderly trading environment, acting as a broker-dealer so that they can easily buy and sell their goods while not being exposed to financial risks.

Trading can be organized according to the type of trade being traded. The old trading is what makes a real trade (instant payment). On the other hand, there is a trade that offers trading alternatives, such as futures and options. Trading can also be classified according to the financial instruments traded: cryptocurrency exchange, stock or securities exchange, commodity exchange, and foreign exchange (Forex). However, most traders offer a variety of services and trading options. For example, many commodities also provide futures trading.

Fiat

A currency that is established as a legitimate currency, usually supported by state law which means it is a legal tender. The word fiat comes from Latin and is a word used to describe a government order, order, or decision. By definition, fiat money is a currency with no internal value as it is not supported by tangible assets and is usually made of non-functional or low-value materials (such as small paper). However, fiat money is widely accepted as a payment method.

Apart from government authorization and control, the main reason why fiat money is considered legal and important in our society is because of a shared belief. In other words, the price of fiat depends largely on the collective agreement that it has a market value and can be used as an exchange, with strong internal purchasing power. Therefore, the adoption of fiat money depends largely on government policy and the social order (and the expectation that it will keep its value in the future). If a social belief or government proclamation becomes compromised, the real value of the currency, as a means of payment, is declining rapidly and very rapidly.

Candidate Block

In short, a candidate block is a block node (miner) that tries to dig a mine to earn a block reward. Candidate blocking can therefore be defined as a temporary blockchain that will be confirmed or discarded by the network. Miners compete to secure the next block and add to the blockchain, but first, they have to build a candidate block in order to participate in the mining competition.

Candidate blocks are created by miners by collecting and organizing many unverified works from memory. The transaction is then accelerated to build the Merle tree structure, which will eventually produce the Merle root (or root hash). The Merle root is a single hash representing all previous horses of that tree, therefore, all transactions placed in that particular block.
