Abstract vs Aurora

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.

Aurora is a Virtual Chain built on NEAR. The first of many. It’s, at the same time, the sandbox and the proof of the robustness of the parent protocol. It’s a smart contract - probably the most complex that exists - that is also an Ethereum Virtual Machine, providing a turn-key solution for developers to operate their apps on an Ethereum-compatible, high-throughput, scalable and future-safe platform, with low transaction costs.
