Not all blockchains are created equal. The term "blockchain" describes a technology architecture that can be deployed in several fundamentally different ways, with dramatically different implications for security, transparency, and investment value. Understanding the four main types is essential for navigating the crypto landscape confidently.
The Four Types of Blockchains
🌍
Public Blockchain
Most Common for Investors
Open to anyone in the world. No permission needed to read, write, or validate. Secured by thousands of independent nodes with economic incentives for honesty. This is the blockchain most associated with cryptocurrency.
Controlled by a single organisation. Participants must be invited and granted permission. Often described as a "blockchain-inspired database." Useful for enterprise record-keeping but offers few of the unique benefits of true decentralisation.
Examples: Hyperledger Fabric, Corda, Quorum
✓ Advantages
Fast transaction speeds
High privacy control
Low operating costs
Compliant with regulations
✗ Limitations
Centralised — defeats the purpose
No public transparency
Single point of failure remains
Not investable as a cryptocurrency
🤝
Consortium Blockchain
Industry Collaboration
Governed by a group of pre-selected organisations rather than a single entity. Common in regulated industries like banking (R3) and supply chain (IBM Food Trust). More decentralised than private chains but less so than public chains.
Examples: R3 Corda, Energy Web Chain, IBM Food Trust
✓ Advantages
Shared governance across trusted parties
More efficient than public chains
Better for regulatory compliance
✗ Limitations
Still partially centralised
Complex governance structures
Limited openness
🔀
Hybrid Blockchain
Flexible Architecture
Combines public and private elements. Some data is public and verifiable; other data is private. Allows organisations to benefit from blockchain security while keeping sensitive business information confidential.
Examples: Dragonchain, XDC Network, IBM + Stellar
✓ Advantages
Customisable privacy settings
Can leverage public security while keeping data private
Flexible for complex business needs
✗ Limitations
Complex to implement and maintain
Less transparent than fully public
Not widely adopted yet
What Matters for Investors
As a crypto investor, the blockchains that matter to you are almost exclusively public blockchains. Bitcoin, Ethereum, Cardano, Solana — these are the networks with native tokens you can buy, hold, and benefit from as their ecosystems grow. Private and consortium blockchains are enterprise tools, not investable assets.
The quality of a public blockchain — its security, developer activity, decentralisation, and real-world adoption — directly influences the value of its native token. Wealtii's index funds are concentrated in the most established public blockchain networks, providing diversified exposure to the most proven assets in the space.

Frequently Asked Questions
What are the different types of blockchains?
Public (Bitcoin, Ethereum), Private (Hyperledger), Consortium (R3 Corda), and Hybrid blockchains. Each offers different trade-offs between decentralisation, privacy, and performance.
Which blockchain type is best for investment?
Public blockchains like Bitcoin and Ethereum offer the most investment value — genuine decentralisation, transparent supply, established liquidity, and powerful network effects. Private blockchains are enterprise tools without investable tokens.
