How is a Polygon supernet different from an Avalanche subnet?

Subnets and Supernets are both scalability solutions for building L1 blockchains quickly. Avalanche uses the Snowman Proof-of-Stake consensus protocol for probabilistic consensus and infinite decentralization, while Polygon’s IBFT consensus protocol guarantees consensus but limits permissionless participation and decentralization. Avalanche processes up to 4500 TPS, while Polygon processes up to 1500 TPS.

Subnets have around 1,300 validators, require a minimum staking amount of 2000 AVAX to become a validator and require all validators to validate the entire primary network. Supernets have 100 validators, need a minimum staking amount of 20,000 MATIC to become a validator, and do not have a similar validation requirement. Supernets and subnets also differ in their approach to Slashing, with Avalanche aiming to prevent centralization of staking while Ethereum favors higher stake validators.

Why is Polygon faster than Ethereum?

Polygon processes transactions on side chains instead of the main chain for faster transaction speeds and lower fees due to lower congestion. Developers can create multiple side chains with customized rules and governance structures to meet specific Web3 needs. Polygon boasts a transaction speed of almost 65,000 transactions per second.

Its consensus mechanism completes the transaction confirmation process in a single block, allowing for an average block processing time of 2.1 seconds, making it much faster than Ethereum. Polygon is a Layer-2 scaling solution for Ethereum that provides a cheaper and faster experience and allows developers to create customized blockchain environments.

What is the difference between Ethereum and the Polygon blockchain?

Ethereum and Polygon have entirely different architectures and use cases for Web3 developers. Ethereum is a standalone blockchain that focuses on supporting decentralized applications and smart contracts. On the other hand, Polygon is a Layer 2 scaling solution that enhances Ethereum’s scalability, speed, and interoperability. Polygon is a Layer-2 scaling solution that mitigates Ethereum’s gas fees, providing users with a more affordable experience.
