Comparison of Bitcoin, Ethereum, and Hyperledger Fabric: Consensus, Smart Contracts, and Programming Languages
This article presents a side‑by‑side comparison of three major blockchain platforms—Bitcoin, Ethereum, and Hyperledger Fabric—detailing their required cryptocurrencies, network types, permission models, consensus algorithms, smart‑contract support, and primary programming languages, and typical use cases.
The table compares three blockchain platforms: Bitcoin, Ethereum, and Hyperledger Fabric.
Cryptocurrency requirement: Bitcoin requires its native bitcoin; Ethereum uses ether and allows user‑created tokens; Hyperledger Fabric does not require a cryptocurrency.
Network type: Bitcoin operates on a public network; Ethereum is public or permissioned; Hyperledger Fabric is permissioned.
Permission model: Bitcoin is permissionless; Ethereum can be public or permissioned; Hyperledger Fabric is permissioned.
Consensus mechanisms: Bitcoin and Ethereum use Proof of Work; Hyperledger Fabric uses PBFT.
Smart‑contract support: Bitcoin has none; Ethereum supports Solidity, Serpent, LLL; Hyperledger Fabric supports chaincode.
Programming languages: Bitcoin core is written in C++; Ethereum clients are in Go, C++, Python; Hyperledger Fabric is implemented in Go and Java.
