Scalability is one of the major challenges faced by most Blockchains and to solve this, several scaling solutions have been adopted by various blockchains. In this Blog, we will compare Avalanche Scaling Solution ( subnet) to the Polkadot scaling solution ( para-chains ).
POLKADOT
Polkadot uses a scaling solution called "parachains" to increase the transaction processing capacity of the network. Parachains are independent chains that run in parallel to the Polkadot Relay Chain and are connected to it through the use of a shared security model.
Each parachain can have its unique features and characteristics, allowing developers to customize and optimize their applications for specific use cases. Parachains can also communicate with each other and share information through the Polkadot Relay Chain, creating a highly interoperable network of chains.
Additionally, Polkadot uses a sharding mechanism called "horizontal scaling" to divide the workload of the network across multiple parallel chains, further increasing the network’s transaction processing capacity. This allows for greater scalability and throughput compared to traditional blockchain networks.
AVALANCHE
Avalanche’s subnet scaling solution involves the use of subnetworks, or subnets, which are parallel chains that run alongside the main Avalanche network. Subnets are designed to increase the transaction processing capacity of the network by allowing for parallel processing of transactions.
Each subnet has its own set of validators who are responsible for processing transactions and securing the network. Validators on one subnet do not have access to the state of other subnets, which increases the security and resilience of the overall network. Additionally, subnets can communicate with each other and with external networks through a set of common APIs and data structures, which allows for greater interoperability.
Subnets can be customized to meet the specific needs of different applications and use cases. For example, a subnet could be optimized for high-speed transactions or privacy and confidentiality. Subnets can also be partitioned or merged as needed, which allows for more efficient use of network resources.
Avalanche’s subnet approach is designed to be highly scalable, as new subnets can be launched quickly and easily to meet growing demand. In addition, the subnet architecture allows for more efficient use of network resources, as the workload can be distributed across multiple subnets.
Overall, Avalanche’s subnet scaling solution is a highly flexible and customizable approach to achieving scalability in blockchain networks.
Below are some potential advantages to Avalanche’s subnet approach compared to Polkadot’s parachains:
Decentralization: Avalanche’s subnets are secured by their own set of validators, which means that each subnet has a high degree of decentralization. This allows for greater resilience and security compared to a shared security model like that used in Polkadot. While Polkadot has a strong set of validators on the Relay Chain, the security of each parachain is ultimately dependent on the security of the Relay Chain.
Flexibility: While Polkadot’s parachains allow for greater customization, Avalanche’s subnets are designed to be more flexible and adaptable. This is because subnets are more standardized and have similar functionality, which makes it easier to launch new subnets quickly and integrate them with existing subnets. In addition, subnets can be partitioned and merged as needed, which allows for more efficient use of network resources.
Interoperability: Avalanche’s subnets are designed to be highly interoperable, which means that they can communicate with each other and with external networks more easily. This is because Avalanche uses a common set of APIs and data structures across all subnets, which makes it easier to integrate with other systems and applications.
