Unlike public blockchains like Bitcoin and Ethereum, enterprise blockchains prioritize privacy, scalability, and governance. Hyperledger Fabric, Corda, Quorum — explore each platform's architecture and real-world adoption cases.

Public vs Private vs Consortium

Blockchain networks fall into three categories based on participation:

Public: Open to all (Bitcoin, Ethereum). Maximum transparency, no privacy
Private: Single organization controls access (Hyperledger Fabric, Corda). Fast, low decentralization
Consortium: Jointly operated by multiple organizations (R3 Corda, Quorum). Industry trust network

Hyperledger Fabric Architecture

Led by IBM and the Linux Foundation, Fabric is the most widely adopted enterprise blockchain.

Channels: Private sub-networks between organizations for data isolation
Chaincode: Smart contracts written in Go/Java/Node.js
Orderer: Nodes guaranteeing transaction ordering (Raft consensus)
MSP (Membership Service Provider): Digital certificate-based identity management

R3 Corda: Financial Specialist Platform

Corda, co-developed by financial institutions, adopts a UTXO model where only relevant parties share transaction data. It's also used in Central Bank Digital Currency (CBDC) experiments.

Industry Use Cases

Finance: JP Morgan Quorum (payments), R3 Corda (derivatives clearing)
Supply Chain: IBM Food Trust (food tracing), Maersk TradeLens (shipping)
Healthcare: MedRec (medical record sharing), PharmaLedger (drug tracking)
Government: Estonia KSI (national data integrity)

Deployment Considerations

First confirm whether you need blockchain: If you have a simple shared DB, a trusted central authority, or need real-time processing, traditional databases may be more suitable.

Blockchain is appropriate when: sharing data between multiple untrusted parties, immutable audit logs are required, or trading tokenized assets.
