Exonum vs Hyperledger Fabric: What are the differences?

Introduction

When comparing Exonum and Hyperledger Fabric, it is important to understand the key differences between these two popular blockchain platforms.

Architecture: Exonum follows a UTXO (Unspent Transaction Output) model similar to Bitcoin, where transactions consume and produce outputs. On the other hand, Hyperledger Fabric utilizes an account-based model like Ethereum, where accounts maintain balances and smart contracts control the state changes. This architectural difference impacts how transactions are processed and the design of smart contracts.
Consensus Mechanism: Exonum uses a combination of Practical Byzantine Fault Tolerance (PBFT) and Proof of Authority (PoA) consensus algorithms to validate transactions. In contrast, Hyperledger Fabric supports pluggable consensus protocols such as Kafka, Raft, and PBFT, enabling more flexibility in choosing the appropriate consensus mechanism based on network requirements.
Smart Contract Languages: Exonum supports programming in Rust, a systems programming language known for its performance and safety features. Hyperledger Fabric, on the other hand, offers support for multiple smart contract programming languages such as Go, JavaScript, and Java, providing developers with a broader range of choices.
Permissioned vs. Permissionless Networks: Exonum is primarily designed for permissioned blockchain networks, where participants are known and have restricted access. In contrast, Hyperledger Fabric is more flexible and can be configured for both permissioned and permissionless blockchain networks, adapting to various use cases and compliance requirements.
Modularity and Extensibility: Hyperledger Fabric is highly modular, allowing developers to customize and extend the framework with pluggable components such as consensus algorithms, membership services, and smart contract languages. Exonum, while also extensible, has a more structured architecture that may require more effort to integrate additional features or functionalities.
Governance and Community: Hyperledger Fabric is managed by the Linux Foundation's Hyperledger project, which comprises a diverse community of developers, organizations, and technology vendors collaborating on blockchain initiatives. Exonum, developed by Bitfury, has a smaller community but benefits from the expertise and resources of the company behind it.

In Summary, understanding the differences between Exonum and Hyperledger Fabric is essential for choosing the right blockchain platform based on project requirements and use case scenarios.

What are some alternatives to Hyperledger Fabric, Exonum?

Ethereum

A decentralized platform for applications that run exactly as programmed without any chance of fraud, censorship or third-party interference.

Tendermint

It is a software which can be used to achieve Byzantine fault tolerance (BFT) in any distributed computing platforms. It consists of two chief technical components: a blockchain consensus engine and a generic application interface.

MultiChain

It is a platform that helps users to establish a certain private Blockchains that can be used by the organizations for financial transactions.

IPFS

It is a protocol and network designed to create a content-addressable, peer-to-peer method of storing and sharing hypermedia in a distributed file system.

Web3j

It is a lightweight, highly modular, reactive, type safe Java and Android library for working with Smart Contracts and integrating with clients (nodes) on the Ethereum network. This allows you to work with the Ethereum blockchain, without the additional overhead of having to write your own integration code for the platform.

Ripple

It is an open source protocol which is designed to allow fast and cheap transactions.

BigchainDB

It is designed to merge the best of two worlds: the “traditional” distributed database world and the “traditional” blockchain world. With high throughput, low latency, powerful query functionality, decentralized control, immutable data storage and built-in asset support.

Eris

It is free software that allows anyone to build their own secure, low-cost, run-anywhere applications using blockchain and smart contract technology.

Litecoin

It is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. It is an open source, global payment network that is fully decentralized without any central authorities.
