How Many Blockchains Are There in the World?

As of 2024 and continuing into 2025, the blockchain ecosystem is booming—there are over 1,000 active blockchains worldwide. These range from well-known public networks to niche enterprise solutions (source). That’s not just a statistic—it’s a testament to how varied and pervasive blockchain technology has become.

Imagine this: a university uses a private blockchain to track research assets, while multiple banks collaborate on a consortium blockchain for cross-border settlements. Blockchains have become a foundation for more systems than most people realize.

How Many Blockchains Are There in Bitcoin?

At first glance, the phrase “blockchains in Bitcoin” may cause confusion. In fact, Bitcoin refers to a single public blockchain, created in 2009 by the pseudonymous Satoshi Nakamoto. It remains the most secure, battle-tested chain today, unlike the thousands of other blockchains serving various purposes (source).

List of Public Blockchains

Public blockchains allow anyone to participate, validate, and verify transactions without permission. Popular examples include:

• Bitcoin
  
• Ethereum
  
• Cardano (source)
  
• Solana (source)
  
• Polkadot (source)
  

These public chains are the backbone of decentralized finance, NFTs, and open-access innovation.

4 Types of Blockchain Networks

Understanding the 4 types of blockchain networks helps make sense of their applications and benefits:

The headline “Types of Blockchain Networks” refers to the different categories of blockchain systems based on how they are built, who can access them, and how participants interact with the network.

In simple words, it’s about the different ways a blockchain can be set up and used.

1. Public blockchains: Fully open and decentralized (e.g., Bitcoin, Ethereum).
   
2. Private blockchains: Controlled by a single organization (e.g., Hyperledger Fabric, R3 Corda) (source).
   
3. Consortium blockchains: Governed by a group (e.g., Canton Network for banks) (source).
   
4. Hybrid blockchains: Blend private control with public verification—offering both privacy and transparency.

So, this headline would usually lead into an article section that explains what each type is, how it works, and where it’s used.

Here’s a visual example showing the distribution of blockchain network types using hypothetical data. It illustrates how public blockchains dominate compared to private, consortium, and hybrid ones.

List of Crypto Blockchains

Focusing just on public networks that power cryptocurrencies, here’s a shortlist:

• Bitcoin (BTC)
  
• Ethereum (ETH)
  
• Solana (SOL)
  
• BNB Chain (BNB)
  
• Tron (TRX)
  
• Avalanche (AVAX) (source, source)
  

Keep in mind that this list includes only the most visible ones—new crypto blockchains emerge regularly.

Step-By-Step: Estimating and Exploring Blockchains

1. Define your scope—are you examining public, private, or crypto-specific chains?
   
2. Use reliable sources—CoinMarketCap for public chains, Wikipedia, enterprise reports for private/consortium ones.
   
3. Aggregate the totals—hundreds of public chains plus countless private or niche networks easily exceed 1,000 chains.
   
4. Stay updated—because new chains appear frequently, revisiting this topic keeps you informed.

An Anecdote to Illustrate

At a fintech conference, a speaker offhandedly said, “We launched a private blockchain for agricultural data.” It hit me—blockchain isn’t just for finance. There are networks for healthcare, voting systems, environmental monitoring, and beyond. Realizing this breadth helps you understand the landscape—and make smarter choices when purchasing blockchain-based tools or services.

“Just like knowing the meaning of a decentralized wallet helps you understand how you control your own funds, knowing how many blockchains there are helps you see the bigger picture of where your digital assets can live.”

How to Choose a Blockchain-Based Product with Confidence

If you’re considering purchasing—or simply using—a blockchain product, here’s how to proceed with clarity:

1. Know your blockchain type—public, private, consortium, or hybrid.
   
2. Assess reputation—chains like Ethereum benefit from large developer communities and audits.
   
3. Evaluate performance needs—public chains offer transparency; private or consortium chains offer speed.
   
4. Understand governance—who controls updates and validations?
   
5. Test before committing—use free tiers, demos, or security audits.
   
6. Stick with known providers—products tied to major chains (e.g., MetaMask on Ethereum) often offer added trust.
   

Following this approach ensures you make educated decisions grounded in real understanding.
