Polygon vs Avalanche Subnetting: Which one is better in recent times? – Cryptosaurus

key points:

  • The polygon supernet is intended to be complete with avalanche subnets.
  • They are programmed with very different rules ranging from consensus protocol and processing capacity to the number of validators.
  • It can be seen that the subnet is better in transaction processing speed than the supernet.
The creation of sidechains (secondary chains) is the preferred paradigm for large blockchains trying to overcome the problem of traffic congestion while expanding their networks (not always layer 2 dependent). The destination is the same, but the implementation of each blockchain will be different; This article will explain the differences between Avalanche’s “subnet” sidechain and Polygon’s “supernet”, as well as discuss the advantages and disadvantages of these two sidechains.

General Details

There have been some recent developments in the Blockchain Launch Pad, including the Avalanche Subnet and the Polygon Supernet. Although the names and functions of supernet and subnet are similar on the surface, there are several important differences.

Subnets and supernets allow the creation of application-dedicated blockchains (application chains). They improve the user experience by reducing volatility in fees, increasing the speed of transactions, and providing personalized network incentives that cannot be achieved with monolithic blockchains.

Without these platforms, building an app chain is prohibitively expensive, dangerous, and knowledge-intensive for most developers. In addition, architects must solve the difficulty of properly motivating the participation of decentralized validators to ensure security.

The Avalanche Subnet and Polygon Supernet arose to address these challenges, by abstracting blockchain domain expertise to establish application-dedicated blockchains and provide blockchain-as-a-service.

What is subnet?

A subnet is a dynamic group of validators who cooperate to come to an agreement on the state of the blockchain. Subnets, in other words, are infrastructures that support application chains by providing validators that can be shared between blockchains. Subnet, in a broader sense, allows developers, builders and entrepreneurs to set up completely custom blockchains within the Avalanche ecosystem. Subnets become available in May 2022.

Subnets are highly customizable and require as few design decisions as possible. Businesses and developers can create blockchains with the flexibility to customize virtual machines (EVM, AVM, or any other VM). Since subnets provide a private blockchain option, companies can create custom blockchains without tokens if their business model does not require them.

The main network of networks is made up of three chains:

  • X-Chain – The payment chain used to create non-fungible tokens (NFTs).
  • C-Chain – a smart contract platform based on the Ethereum Virtual Machine for the development of decentralized applications.
  • P-Chain: Responsible for the coordination of validators in the avalanche, as well as the creation and management of subnets.

The main subnet, which includes all validators, keeps the Avalanche network running. It is their responsibility to verify the core network as well as the X, P and C chains, allowing validators to validate new blockchains built on the network and facilitate communication between subnets.

What is Supergrid?

SuperGrid is a colloquial term for a software program that allows developers, builders and entrepreneurs to create their own application chain and end application chain.

The program provides access to a professional collection of validators, third-party implementation, design and management services, and tools (including block explorers, wallets, and KYC providers) for out-of-the-box integrations. Polygon Edge, Polygon’s flexible and modular framework for developing Ethereum-compatible blockchains, is the technology that powers SuperGrid.

Polygon Edge has two supported consensus types: Istanbul Byzantine Fault Tolerance (IBFT), Proof of Authority (PoA), and IBFT Proof of Stake (PoS). Both IBFT consensus protocols are official protocols that require a set of trusted validators prior to consensus, with a theoretical maximum of 100 validators that can participate in consensus. IBFT POA is best suited for private networks where the trust of validators is strong, such as in many corporate use cases. In contrast, IBFT PoS allows any validator from a set of trusted validators to participate in consensus.

SuperNets are the technical troubleshooters for Polygon’s development framework, Polygon Edge. Polygon Edge helps build Ethereum-compatible blockchains that are secure, decentralized, and efficient.

Interoperability, exclusivity, increased scalability, security, and better decentralization are all benefits of using Polygon Supergrids. Supernet is also excellent at addressing issues with polygon edge technology, specifically on-chain configuration and bootstrapping decentralized validator sets.

35 Edge Projects have been created since the first Edge Project was implemented in May 2021.

IBFT consensus guarantees stability if less than a third of validators misbehave, either maliciously or due to downtime. Over time, it is likely that more consensus protocols will be supported. Polygon Edge’s current consensus process provides instant finality, and community members can delegate to Polygon validators.

Developers working on the Polygon Network have access to a variety of validators and tools for easy integration, as well as third-party services to help with implementation, design, and maintenance.

SuperGrids can be maintained by a certified third party in two ways: Sovereign Chain (the blockchain is validated by their own validators) and Shared Security Chain (the blockchain is validated through a provided set of MATIC stakeholder validators is done).

subnetting vs supernetting

Avalanche consists of a system of subnets with dynamic validators that work together to achieve consensus. Furthermore, they are an application chain infrastructure that provides validators that can be shared between blockchains. With these subnets, completely custom blockchains can be built on Avalanche.

Polygon’s version of this application chain infrastructure is called a supernet. SuperNet provides validators, third-party implementation services, design, management, and tools for rapid integration. Additionally, they are powered by Polygon Edge, a modular framework for building Ethereum-compatible blockchains.

Both the systems look similar, but there are actually some differences.

One of the main differences between subnet and supernet is the core consensus protocol. The Snowman consensus protocol used by Avalanche allows for theoretically infinite decentralization and scalability by providing probabilistic consensus among validators. Polygon’s IBFT consensus protocol guarantees consensus, but at the cost of decentralization and permissionless loss of participation.

Additionally, supernets have slicing capabilities that can punish bad actors on the network. Avalanche does not use this mechanism for fear of centralizing stakes.

Avalanche boasts a high performance of 4,500 transactions per second. The polygon is approximately 1,500. There are also more validators in the avalanche subnet, with 1,300 compared to only 100 in the supernet.

  • Regarding operation: The subnet acts as a small “slice” of the avalanche. Instead of creating a single blockchain, developers will set up multiple parallel blockchains while maintaining Avalanche’s advantages such as security, speed, and community.
    However, the goal of a supernet of polygons is quite different. A supernet is designed to link current crypto applications, such as DeFi, GameFi, and even Web3, and improve network interoperability, while the native blockchain will handle transactions.
  • In terms of scalability, there will be a smaller replicated range within the subnet avalanche architecture. Developers will use the Avalanche’s unique network addresses to create subnets.
  • On the other hand, a supernet is known as a “network of networks” because it can consist of subnets and many other networks. Each supernet can exchange values ​​and messages with other supernets as well as with the main Ethereum network.
  • Regarding security: Due to the purpose and magnitude of the two types of subnets, they have their security advantages and disadvantages. Since it is controlled individually, subnets are valued for their security. In particular, a single perturbation will have little effect on the entire large range.
  • On the other hand, Supernet is more vulnerable to attacks due to its multi-network connectivity strategy, which complicates the maintenance of the system.


Based on the current scenario, both Polygon and Avalanche have invested significant resources in their respective supernet and subnet application chain solutions, such as using native tokens for incentives and partnering with other industry providers to provide optimized services To cooperate, so that related projects are completed quickly. and deployed.

However, currently there is no exemplary project available for these two options. As can be seen, App Chain is not a suitable development recipe for project parts. The Polygon Supernet mainnet is yet to be launched and the focus of Polygon’s scaling solution is a range of alternatives including zkEVM.
