how to build a custom blockchain in an easy way.

In this blog, I’ll briefly describe to you how to develop custom blockchains using blockchain-building frameworks.

In the past, developing and maintaining the core blockchain was difficult and expensive, but recent technological advancements have simplified the process in this domain. Developing custom blockchains for specific purposes is now easy with blockchain technologies like Polkadot’s Substrate, Cosmos, and Horizen, which offer interoperability through layer 0 blockchains. Blockchain interoperability enables application-specific blockchains to communicate through layer 0 networks.
Let’s discuss cutting-edge blockchain technologies.

Substrate

The substrate is an open-source framework for creating custom blockchains, including those tailored for specific use cases. Polkadot, a layer 0 blockchain, is built on Substrate and supports communication between other parachains in the network. Parachains are heterogeneous blockchains linked to Polkadot.

Prerequisite to start learning Substrate:

Advance hands-on knowledge of the Rust Language
- Asynchronous Programming (Tokio)
- Generic Programming
- Traits
- Macros and Meta Programming
- Libp2p
Deep knowledge of Consensus and Networking
Technical knowledge of different blockchains

To start learning the Substrate, go to the documentation: https://docs.substrate.io/

Cosmos

The Cosmos SDK is the leading framework for building application-specific blockchains that can participate in inter-chain communication through the Inter-Blockchain Communication Protocol (IBC). These blockchains are part of the Cosmos network and use Tendermint consensus.

Prerequisite to start learning Cosmos:

Advance hands-on knowledge of the Go Language
- Protocol Buffer and gRPC
- Goroutines and Channels
Deep knowledge of Consensus and Networking
Technical knowledge of different blockchains

To start learning the Cosmos, go to the documentation: https://tutorials.cosmos.network/academy/1-what-is-cosmos/

Horizen

Horizon is a highly secure and interoperable blockchain ecosystem with a decentralized multi-tiered node infrastructure.

The Horizen Sidechain SDK enables developers to rapidly create a customized blockchain with tailored business logic while maintaining interoperability with the mainchain native token as a medium of exchange.

To start learning the Horizen, go to the documentation: https://docs.horizen.io/en/latest/
