Custom Blockchain

Distributed database

Blockchain (chain of blocks) is a system for storing and transmitting information in sequential chains of transaction blocks. Blocks are included in a single database, automatically updated with each new transaction.

In simple terms, a blockchain is a database that simultaneously works on thousands of computers (nodes) so that each of them always contains the most up-to-date information. Thanks to this, decentralization is achieved. That is, there is no "main server", as we are used to seeing it.

The main principle is the transparency of all transactions (each participant can view any transaction at any time) with the impossibility of changing them over 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, "backdating", since this will affect all earlier blocks up to the very first one.

At the stage of its appearance, blockchain technology was used exclusively for cryptocurrency, and a little later, it was adopted by some banking structures. However, in its development today, the new system penetrates our daily life quite profoundly. For example, platforms for developing business applications based on blockchain technology can even control copyright compliance, tracking the production processes of a particular product for its compliance with the declared standards, not to mention absolutely all financial transactions.

Private and public blockchains

A public blockchain's advantage comes from its user community acceptance. In addition, we use existing blockchain platforms such as Ethereum to develop decentralized applications, also known as DApps.

For companies needing security and privacy that offer private blockchains, we can create a custom blockchain solution to suit your needs. In addition, customizable DApps on your private blockchain allow you to manage financial records, build contracts, control inventory, track logistics, and more.
