Blockchain is a technology for storing information about transactions. This is not a separate network with fans of video cards, which mints some coins with the letter “B”, no, everything is much wider and more diverse.
Modern terminology has entered the chat along with innovations, more and more new gadgets are appearing every day, now, to earn without leaving home, we are talking about traders who trade on Bitsgap platform, earn BIG money sitting in their underpants and T-shirt in front of the computer, which is extremely annoying to the authorities, who are tirelessly looking for alternative ways settlements and payments. Let’s talk about what a blockchain is, and why, like a phoenix, it rose from the ashes and indicated its relevance.
What is it?
The very concept of this technology implies a decentralized system for conducting transactions without a so-called guarantor. A kind of variation of digital anarchy. What’s the point here? If we take settlements between individuals by money transfers from card to card, then in this chain we will find a harmful intermediary – a bank. The Bank will act as a guarantor and regulator. It stores all the records of the transaction, it can allow the transaction, it can refuse, or it can simply merge all the data to the “security service”.
It’s not like that in the blockchain system. There is only a sender and a receiver. The remaining participants act as “witnesses” who record the transactions carried out and keep records of them.
All these records, which are stored on each user’s computer, are called transaction accounting. This is the main trick: each record is stored not on one server, which is vulnerable to hackers, but on many anonymous computers-anonymous. And if some users are attacked, or try to influence the registry themselves, nothing will come of it, all records will remain in the form in which they were originally.
A chain of blocks that exists exclusively in virtual form. Here we will omit the technical part and the basics of computer science and switch to human language. Transaction records are “pressed” into a so-called block (as if folded into a large folder). when the space in the block ends, it closes and the system opens a new block. Thus, each subsequent block is connected to the previous one.
This whole chain of blocks is called the blockchain.
By the way, in bitcoins and other cryptocurrencies – there is a reward for users for maintaining registers and creating new blocks. This is an analog of a bank commission. Well, how about without incentives?
How Does Blockchain Work?
Blocks and transactions are the two different kinds of records that make up a blockchain system. In order to put it simply, transactions are the acts performed during a specific time period and are kept together in a block.
Blockchain is more distinctive due to the fact that every block includes the cryptographic assortment of the one before it, making a chain. The cryptographic clutter will shift information from the previous block into a short string. As it is hard to foresee these sequences, meddling with the chain can be observed quickly.
With this system, blocks no longer need sequence numbers because the hash enables them to be easily identifiable, and their integrity can be validated. From the beginning of the chain, every block verifies the accuracy of the one before it.
However, the chain is not simply kept safe by the connection of the blocks. Additionally, it is decentralized with a copy of the blockchain that is upgraded with new blocks on every computer that has the software.
No centralized server is used to store the transactions. In addition to that, as every new block should adhere to the chain’s rules, no one can erase earlier transactions. In order to specify what includes in a legitimate entry, more transaction conditions might be applied.
Where is it used?
The range of applications is quite wide: from non-cash payments to presidential elections.
The peculiarity and advantage of the blockchain are that the assets here can be any: crypt, the mortgage on a house, socks, IOUS, furniture. By the way, organizations involved in depositing also use blockchain technology.
Smart contracts are also gaining popularity. This is a completely new concept in the legal world, which scientists and practitioners are arguing about. But, undoubtedly, in the future, it will gain a dominant position in business and trade processes.
What Are The Primary Advantages of Blockchain
There are various types of blockchain, such as public blockchain networks, private blockchain networks, permissioned blockchain networks, and consortium blockchains. Here are the best benefits of blockchain.
All blockchains have decentralization as their fundamental component. Since there is no governing authority, all investments are built via a concord open-source algorithm that can be auditable by any person. In addition, it lets stoners deal directly with one another and maintain complete ownership of their investments.
Enhanced privacy and security
Blockchains have more security since they are decentralized. Hackers are not able to take advantage even of a single point as the ledger is shared across plenty of different users. Besides that, due to the cryptography’s unhackable nature, funds in the wallet might not be jeopardized until a user error occurs.
The shared ledger is likewise artificial, even if it is totally transparent. It delivers even more anonymity because transactions do not have any connection to the user’s identity.
Highly visible and traceable
The blockchain ledger is totally open for public inspection and is completely transparent. Users can look into the source of any transaction and follow it back to its beginning. It is very beneficial in circumstances when payment tracing is crucial.
The lower fee of blockchain transactions is one of the perks in comparison to more conventional banking-based financial payments. Due to their borderless essence and lack of conversion fees, this makes them very flexible for making money transfers across nations.
If the trigger’s requirements are satisfied, it can be programmed to automatically produce a series of activities, events, and transactions.
