Subnet – The Key to Avalanche's Infinite Scalability

Scaling blockchain is a challenge and topic has always been researched by blockchain developers in recent years, every day developers are always looking for the most suitable way to bring blockchain to millions of new users. join the vast space of blockchain.

Ethereum's high gas fees and Solana's multiple outages show how important scaling solutions have become, especially for the future of DeFi.

And Avalanche – An open-source, smart contracts platform for launching dApps and implementing enterprise blockchains in an interoperable, highly scalable ecosystem has another potential solution of its own. Avalanche takes a unique approach to this with Subnet, a scaling solution on top of Avalanche that allows anyone to create their own Layer 1 blockchain.

So what is a subnet? Why Subnet will be the key to Avalanche's limitless scalability potential? Please take a look at the details of BTA Hub's article!

What is subnet?

Subnet (subnet) is 1 prize The scaling method on Avalanche allows anyone to create their own Layer 1 blockchain. It consists of a dynamic subset of Avalanche validators working together to reach consensus on the state of one or more blockchains. Each blockchain is validated by exactly one Subnet, and a Subnet can have multiple blockchains. Validators can be members of multiple Subnets.

Each blockchain is validated by exactly one subnet, and one subnet can authenticate for many different blockchains.

Avalanche's 3 integrated blockchains: Platform Chain (P-Chain), Contract Chain (C-Chain) and Exchange Chain (X-Chain) are validated and secured by all Avalanche Validators creating a Subnet special and called Primary Network.

Features of Subnet

  • Designed to scale horizontally, which means multiple blockchain networks can operate in parallel and connect with each other.
  • Users can create an unlimited number of Subnets on Avalanche with different uses, DApps or Blockchain networks can build their own subnet. and can be written in languages ​​like Solidity.
  • Assets on different subnets can interact and move back and forth without using a bridge, which will limit hacker attacks.
  • Subnet is an extension of the Avalanche network, creating Blockchains that work independently, compatible with virtual machines (Virtual blockchain) such as Ethereum's EVM, Bitcoin Script, Solana's engine, etc.
  • Large dApps built on Ethereum or other blockchains such as Solana, Cosmon, etc. can build an additional branch of the network operating on Avalanche with low gas fees and high transaction speeds.

Scale with Subnet

Subnets are similar to sharding, instead of creating new versions of the blockchain that are identical, they form separate versions. The difference between them is that users launch subnets instead of algorithmically generated ones.

In addition, you can create unlimited chains for different niche use cases through Subnets. For example, you can launch the second thread after using the first thread.

Many validators can validate different types of Subnets, while they can also validate the default Subnet. The only concern about scale is that they can't do cross-chain transfers on the P-chain, which is very efficient. Subnets can also launch their own thread if needed.

One of the most important advantages of Subnets is that they never run out. Whenever you reach the expansion limit, you can still create new ones.

Subnet – the future or just a passing moment?

Despite the efforts of a lot of different blockchains to solve scalability. Even with the various advantages of scaling solutions, those solutions have to sacrifice some important points. in The 3 big problems of blockchain” are: scalability, decentralization and security to achieve better throughput. However, the Subnet does not sacrifice the security and decentralization of the Avalanche network. Thanks to the flexibility of the Subnets, it will also be possible to create regulatory and secure blockchains. 

Subnets, on the other hand, simply build on top of the Avalanche Mainnet. Optimizing traffic with the use of native tokens for gas fees and custom networks opens the door to a variety of use cases. Regulatory and secure blockchains will also be possible thanks to the flexibility of subnets.


Subnet is considered a unique approach of Avalanche and is considered the key to Avalanche's limitless scalability potential. With many incentive programs and the need to provide a more user-friendly experience of projects with high transaction throughput, in the future Subnet is expected to be the favorite destination of many projects that want to solve the problem of high transaction volume. extend.

Hopefully, through the article of BTA Hub, it will help everyone to have more useful information about the Subnet and don't forget to continue to follow the next articles of BTA Hub!
