Interaction of Blockchain Network Nodes


Today, the crypto market offers a large number of different blockchain projects that need implementation. It is obvious that the delay in the practical application of many such projects is often associated with both the lack of supporting infrastructure and the need for its constant maintenance. Since nodes are one of the fundamental elements of blockchain infrastructure, their deployment is a necessary and important task for every developer. At the same time, the choice of options for deploying blockchain nodes depends on the desires and capabilities of the developers themselves. This means that any author of his blockchain project can follow one of two paths, namely: deploy a node on his own or analyze proposals for deploying nodes from any provider of such a service. It should be noted that the most trusted and preferred suppliers offer different options for using nodes to access the blockchain, among which we can highlight the most reliable and secure –

Role tasks of nodes

Nodes in the blockchain network interact with each other, performing their own tasks. This statement can be illustrated by imagining a certain conditional node of a certain conditional blockchain network. A classic node includes three local systems: a system that services the wallet (W), a mining system (M), a network system that is responsible for P2P interaction with other network participants (N) and a system that is responsible for storing blockchain information (B ). System B is essentially a blockchain database and all other systems constantly interact with it. This is how the miner works with this database in order to obtain information about transactions and previous blocks. System N accepts very time new transactions and adds new blocks to the database. System M generates new transactions, which go to the network, and then enter the database through system N . 

Let’s look at the main combinations of these systems. The classic combination is the node of the so-called “full client”  with support for all local systems of the node. The second version of the node is a combination of only systems B and N. This means that in such nodes it is impossible to create a wallet, account and transactions, and there is no mining process. Processes in such nodes involve only creating information and placing it in the network database. The third combination of local node systems involves individual mining and includes the M, B and N systems. This means that the miner must have complete information about the blockchain and he is able to send new transactions to the network. The fourth combination of systems classifies the node as a “light client” that can only create accounts and send transactions to the network. Some blockchain networks, particularly Bitcoin, may have additional node options that are specific to those networks.

Considering the nodes of the blockchain network separately, it should be noted that each of them, in itself, acts as a so-called wallet service. This means that by logging into a node through a special console, you can call certain commands, for example: “create a wallet”, “create a transaction”, etc. After creating any command, the service starts by default and thereby gives a chance to carry out the necessary actions on the network. In some cases, this approach is not always convenient, and if the user wants to have a more advanced interface, he can use other communication channels, such as IPC or RPC. They are considered as a special protocols that are used to ensure that various applications communicate with each other. At the same time, IPC is used mostly for local connections, and RPC for remote ones.


The practical aspects of blockchain technology demonstrate its serious potential, and conversations about how blockchain technology can change global economic processes constantly occur among developers, business representatives and experts. There are many different institutions that constantly monitor and study the current situation and trends in the ways of moving valuable assets, financial flows and any economic processes in general. Blockchain is a relatively new technology, but the ideas for a new institutional approach to economic processes originated many years ago. As these ideas evolve, not all experiments have been successful in the past, and certainly not all blockchain-related experiments will be successful in the future. Blockchain is only at an early stage of its development and it is not yet fully clear how it can be used in the economy with maximum effect. However, it is already clear that blockchain technology gives the world the opportunity to create data relating to absolutely any trade relationship in a completely new way, based on the principles of decentralization.
