How to set up a KalyChain node

KalyChain Setup for Nodes, Validators & RPC Services

Contributing to KalyChain which is a Hyperledger Besu based blockchain network with an IBFT 2.0 consensus system can provide a number of benefits and have great importance in the context of enterprise networks and consortia. Below is a conclusion about the benefits and importance of this contribution:

The benefits of contributing to the KalyChain network are manifold. First, the adopted consensus system offers high throughput and scalability, allowing transactions to be processed efficiently and handling increased volume of activity as the network grows. In addition, the power efficiency of IBFT 2.0 PoA reduces power consumption compared to more resource-expensive consensus systems.

Another key benefit is the increased security offered by the IBFT 2.0 PoA consensus system. By selecting trusted validator nodes, the risk of malicious attacks is significantly reduced. In addition, the rapid completion of blocks allows for early detection of suspicious activity, strengthening network security.

Contributing to a KalyChain network with IBFT 2.0 also means participating in the governance of the network. This provides the opportunity to influence the development and direction of the network, making decisions related to protocol updates, consensus rules, and system evolution. This participation in governance is crucial to ensure that the network adapts to the changing needs and requirements of the participants.

In terms of importance, the contribution to a blockchain network with IBFT 2.0 PoA is especially relevant in business environments and consortia. It provides a scalable, efficient, and secure solution for enterprise deployments, where reliability and performance are critical. In addition, KalyChain offers a flexible and modular platform that makes it easy to integrate with existing systems and implement specific solutions for different business use cases.

So… let’s start from beginning The first thing you will have to do with is a server that has at least the following characteristics:

System requirements

Operating System: Ubuntu 20.04 LTS 64 bits


Hardware minimum desired
CPU’s: 2 4
Memory: 4 Gb 8 Gb
Hard Disk: 100 Gb 1000 Gb

However, not so soon gale, first we advise you to establish protocols or configure robust security layers within the server to prevent any type of vulnerability, do not forget that if you are an authorized node in the consensus protocol (PoA) you could lose your assets .

After you have strengthened your security layers, we are going to open the following ports


You’ll need to open the following ports in both ways to deploy a node:

Validator Node

Port Type To Definition
30303 TCP Ethereum client listener and discovery ports
30303 UDP Ethereum client listener and discovery ports

Regular/RPC Node

Port Type To Definition
30303 TCP Listener and discovery ports
30303 UDP Listener and discovery ports
8545 TCP (this can be internal only) RPC HTTP Port
8546 TCP (this can be internal only) RPC WS Port


After having enabled all the ports, it remains to finish installing and configuring the server, then we will give you some tips or security improvements that you can implement on the server, it is found in the Server Setup

Installation & configuration

Server Setup

Start with server setup in the server directory

Regular node

Regular nodes are network participants that can send transactions and query the status of the blockchain. These nodes do not have the power to validate transactions or add blocks to the chain. However, regular nodes can interact with validator nodes to send and receive transactions, and get up-to-date information about the state of the network.

Use the regular directory ti install a regular node

RPC node

An RPC (Remote Procedure Call) node on a Hyperledger Besu-based blockchain is a service that enables communication between an external application or client and the Besu blockchain network. It provides an interface that allows you to make requests and receive responses to interact with the blockchain.

The RPC node in Hyperledger Besu has several functions and utilities:

  1. Data queries: Allows you to query the block chain to obtain information about blocks, transactions, account balances, events, among other relevant data. Clients can use the RPC node to get up-to-date information about the state of the chain and perform analysis or make decisions based on this data.
  2. Sending transactions: Through the RPC node, users can send transactions to the Besu blockchain. This allows you to interact with smart contracts and execute operations defined on them. It can be used to perform digital asset transfers, execute automated business logic, and perform specific actions on the blockchain.
  3. Integration with external applications: The RPC node in Besu makes it easy to integrate the blockchain with external applications and systems. It allows web services, mobile applications or other platforms to interact with the Besu blockchain and take advantage of its functionality. This enables the construction of decentralized applications (DApps) and interoperability with other services and systems.
  4. Development and testing: The RPC node is especially useful during development and testing of applications based on the Besu blockchain. It allows developers to interact with the blockchain locally, submit transactions, and perform queries without the need to set up an entire network. This facilitates the process of developing and testing applications based on Besu.

To install an RPC node use the rpc directory

Validator node

Validator nodes are selected by a predefined group of authorities to be responsible for validating and adding transactions to the blocks on the chain. These nodes have the power to actively participate in the consensus process and contribute to the security and integrity of the network. Validator nodes use their ability to digitally sign blocks to prove their authority and ensure the validity of transactions.

Use the validator directory to install a Validator node


In conclusion, contributing to the KalyChain network brings significant benefits, including high throughput, scalability, energy efficiency, enhanced security, and participation in governance. This is of great importance in enterprise and consortium environments, where reliability, performance, and adaptability are required to meet specific business needs.
