About Web 3.0 Development in Simple Words
Preamble
Often, when experts are talking about “the future that is almost here”, they mean the development of the third generation Internet and the opportunities for humanity that should follow this development. And this is natural, since the Internet has a huge impact on all aspects of our lives, and this influence is only increasing. According to experts and analysts, the concept of Web 3.0 will completely change the global economy and blockchain technology will play a leading role in this. Now companies, corporations and even entire countries should quickly master the new technologies and tools that Web 3.0 brings to our lives and business.
Of course, the development stage of Web 3.0 technologies is still in its infancy, but many users are already taking advantage of the benefits that these technologies can provide them now. And one of the key roles here is played by decentralized infrastructure packages, which ensure the most successful implementation of Web 3.0 technologies. Based on this, we can safely say that the expansion of developments in the field of web3 infrastructure projects will become a powerful catalyst for the further advancement of new decentralized technologies and tools.
First steps and main components of blockchain technology
If we penetrate the environment of IT developers, we can hear their opinion regarding how rare mentions of extant blockchain developments are. It may seem that, except for the cryptocurrency sector, no other branch of human activity needs projects opened to blockchain technology. In order to confirm or refute this opinion, it is necessary to recall the basic definitions of blockchain technology.
Let`s keep in mind, that the blockchain itself started its voyage as a decentralized innovational repository, in which it was initially schemed to preserve the cryptocurrency – bitcoin. Its advantage was that it could not be hacked due to the lack of centralized control of this system. Further, creators came to the conclusion that in this way it is possible to store not only money, but also many other various effects, let us say, contracts, property rights, etc. To implement this task, smart contracts were developed.
At their core, smart contracts are now nothing more than applications on the blockchain, a kind of specific class in object-oriented programming. It is known that smart contracts owe themselves emergence to Ethereum. They are part of code written in some programming language, in particular, Solidity. Smart contracts are situated on the blockchain platform, compiled into byte code, laced into a transaction and sent. In Ethereum, each smart contract has its own ABI (Application Binary Interface), thanks to which the user can see the necessary actions specified in the smart contract. Each smart contract, which replaces the backend in blockchain technology, is connected to the frontend. And since the smart contract is located on a decentralized blockchain network, it is possible to represent it as a decentralized application (DApp). The difference between a DApp and a regular application is the absence of classic registration by email or by login and password. In classic registration, a similar login and password are either used to log into different platforms or saved somewhere. In decentralized applications, the user can authorize only through his crypto wallet, which implies the use of a personal key. This approach to authorization leads to a more secure and convenient work with applications, which means that in the near future, working with DApps will significantly reduce the use of regular applications.
Levels and facilities of applying of blockchain
Despite verity of blockchain technology which implies equability of all network users, there is still a certain gradation of these users. The first user option is the simplest. It consists in the fact that the user creates a regular client application (wallet), which displays his residue, and transmits transactions to the blockchain network. The next level of user is a more advanced one, it permits the utilizer to download the utter option of the blockchain and raise their own node. This user option is very useful for the network, since the more users raise their node, the more decentralized this network is considered. The higher level of the user is that he not only raises his node, but also becomes either a validator or a miner, depending on the platform consensus. By adding new blocks or sustaining transactions, active partakers contribute to evolution of the blockchain network.
It`s evidently that blockchain technology is a kind of generator for the development of Web 3.0. In turn, at this stage, the third generation Internet is, first of all, a kind of philosophy, and not a set of rules and instructions. This philosophy encloses profits such as non-centralized administration of the blockchain web, as well as ownership and self-management of your own data on the network. In addition, web 3.0 projects are already in development, which are aimed not only at the ability to manage one’s data, but also at the ability for any user to train their own recommendation system to create stable algorithmic schemes.
