Blockchain-based service development

DE2COM specialists are developing blockchain-based services

The development period depends on the complexity of the project and takes from 1 to 12 months.

Blockchain services development.

Blockchain (from the English “block chain”) is a continuous sequential chain of blocks (linked list) built up according to certain rules that contain information. Most often, copies of block chains are stored on many different computers independently of each other. Blocks are included in a single database, which is automatically updated every new transaction.

In simple terms, Blockchain is a database that simultaneously runs on thousands of computers (nodes), so that each of them always contains the most relevant information. Thanks to this, decentralization is achieved, that is, there is no “main server", as we used to see it.

The basic principle is the transparency of all operations performed (each participant can see any operation for any time) with the impossibility of changing them in past periods. Each block in this database contains information about the previous block. Therefore, it is impossible to change the information in a separate block “retroactively”, as this will affect all previous blocks up to the very first.

At the stage of its emergence, Blockchain technology was used exclusively for cryptocurrency, and a bit later it was adopted by some banking structures. However, today in its development the new system penetrates our everyday life quite deeply. Platforms for developing business applications based on Blockchain technology can even control copyright compliance, tracking the production processes of a product for its compliance with the stated standards, not to mention absolutely all financial transactions.

Blockchain programming.

The development of projects on the blockchain requires developers to have knowledge not only of programming languages, but also of a deep understanding of the principles of operation of decentralized applications, as well as cryptography.

Development of smart contracts.

Smart contract (eng. Smart contract - smart contract) is a computer algorithm designed to conclude and maintain commercial contracts in blockchain technology.

The parties sign a smart contract using methods similar to the signing of sending funds in existing cryptocurrency networks. After signing by the parties, the contract takes effect. To ensure the automated fulfillment of contractual obligations, an environment of existence is required, which allows to fully automate the implementation of contract clauses. This means that smart contracts can only exist inside an environment with unhindered access of executable code to objects of a smart contract. All conditions of the contract should have a mathematical description and a clear logic of execution. In this regard, the first smart contracts have the task of formalizing the simplest relationships, consisting of a small number of conditions. Having unhindered access to the objects of the contract, a smart contract monitors the achievement or violation of points under the specified conditions and makes independent decisions based on programmed conditions. Thus, the main principle of a smart contract is the complete automation and reliability of the execution of contractual relations between people
