Understanding the foundational structures behind Web3 and decentralized technology
Blockchain isn’t just Bitcoin, and it certainly isn’t one-size-fits-all. As industries explore this revolutionary technology, different types of blockchains have emerged — each with its own strengths, use cases, and trade-offs.
Let’s break down the major types of blockchains and how they’re used in the real world:
1. Public Blockchains
What it is:
Public blockchains are open, permissionless networks. Anyone can join, view, or validate transactions.
Examples:
Bitcoin
Ethereum
Solana
Avalanche
Primary Use Cases:
Why it matters:
Public chains champion transparency, decentralization, and censorship resistance — ideal for building truly trustless applications.
2. Private Blockchains
What it is:
These are permissioned networks controlled by a single organization. Access and validation rights are restricted.
Examples:
Why it matters:
Enterprises use private blockchains for secure, scalable, and compliant data processing while maintaining control over the network.
3. Consortium (Federated) Blockchains
What it is:
A blockchain managed by a group of organizations instead of one or the public. It offers a balance between decentralization and control.
Examples:
Why it matters:
Consortium chains are great for industries where collaboration and trust among known entities is required.
4. Hybrid Blockchains
What it is:
Hybrid blockchains combine features of both public and private blockchains. Some parts are open, others are restricted.
Examples:
Why it matters:
Hybrid chains offer flexibility for organizations that need both transparency and privacy in different parts of their operations.
Bonus: Sidechains & Layer 2s
What they are:
These are scaling solutions, not types of blockchains per se.
Sidechains are independent blockchains connected to a main chain.
Layer 2s are built on top of existing blockchains to offload congestion.
Examples:
Why it matters:
They make blockchain applications more practical for everyday users by reducing gas fees and increasing speed.
Conclusion
Each type of blockchain serves a specific purpose — from global digital currencies to enterprise-grade data platforms. The key is understanding what you’re building and who it’s for.
Web3 isn’t one chain to rule them all — it’s an ecosystem of interconnected technologies solving different problems.

What it is:
Public blockchains are open, permissionless networks. Anyone can join, view, or validate transactions.
Examples:
Bitcoin
Ethereum
Solana
Avalanche
Primary Use Cases:
- Cryptocurrencies
- Smart contracts & dApps
- Decentralized Finance (DeFi)
- NFTs and digital ownership
- DAOs (Decentralized Autonomous Organizations)
Why it matters:
Public chains champion transparency, decentralization, and censorship resistance — ideal for building truly trustless applications.
2. Private Blockchains
What it is:
These are permissioned networks controlled by a single organization. Access and validation rights are restricted.
Examples:
- Hyperledger Fabric
- R3 Corda
- Quorum
- Primary Use Cases:
- Internal enterprise solutions
- Healthcare data privacy
- Banking operations
- Legal document management
Why it matters:
Enterprises use private blockchains for secure, scalable, and compliant data processing while maintaining control over the network.
3. Consortium (Federated) Blockchains
What it is:
A blockchain managed by a group of organizations instead of one or the public. It offers a balance between decentralization and control.
Examples:
- IBM Food Trust
- Marco Polo (trade finance)
- Energy Web Foundation
- Primary Use Cases:
- Supply chain transparency
- Interbank payments
- Industry-wide coordination
Why it matters:
Consortium chains are great for industries where collaboration and trust among known entities is required.
4. Hybrid Blockchains
What it is:
Hybrid blockchains combine features of both public and private blockchains. Some parts are open, others are restricted.
Examples:
- XinFin (XDC)
- Dragonchain
- Primary Use Cases:
- Regulated DeFi
- Enterprise solutions with public data integration
- Identity & access management
Why it matters:
Hybrid chains offer flexibility for organizations that need both transparency and privacy in different parts of their operations.
Bonus: Sidechains & Layer 2s
What they are:
These are scaling solutions, not types of blockchains per se.
Sidechains are independent blockchains connected to a main chain.
Layer 2s are built on top of existing blockchains to offload congestion.
Examples:
- Polygon (Layer 2 for Ethereum)
- Arbitrum
- Optimism
- Liquid Network (Bitcoin sidechain)
- Primary Use Cases:
- Microtransactions
- Gaming
- Scalable dApps
- Cheaper and faster DeFi
Why it matters:
They make blockchain applications more practical for everyday users by reducing gas fees and increasing speed.

Each type of blockchain serves a specific purpose — from global digital currencies to enterprise-grade data platforms. The key is understanding what you’re building and who it’s for.
