Polkadot Ecosystem vs Abstract

Polkadot stands out among other blockchain projects for its focus on enhancing the foundational infrastructure of dApps. It aims to enable interoperability between blockchain ecosystems, facilitating seamless communication without intermediaries. Functioning as a "network of networks," Polkadot utilizes parachains — specialized blockchains with unique functionalities and tokens — to enable interaction between diverse blockchain architectures. Powered by the nominated proof-of-stake (PoS) consensus algorithm and drawing inspiration from the Ouroboros protocol, Polkadot offers a robust framework for building interconnected and scalable decentralized systems.

Abstract is a Layer 2 (L2) network built on top of Ethereum, designed to securely power consumer-facing blockchain applications at scale with low fees and fast transaction speeds.

Built on top of the ZK Stack, Abstract is a zero-knowledge (ZK) rollup built to be a more scalable alternative to Ethereum; it achieves this scalability by executing transactions off-chain, batching them together, and verifying batches of transactions on Ethereum using (ZK) proofs.

Abstract is EVM compatible, meaning it looks and feels like Ethereum, but with lower gas fees and higher transaction throughput. Existing smart contracts built for Ethereum will work out of the box on Abstract (with some differences), meaning developers can easily port applications to Abstract with no or minimal changes.
