Going beyond limits: Bitcoin, Ethereum, and a new foundation for the digital world

Starknet, originally an Ethereum Layer 2 built on STARK proofs, is extending its scalability framework to Bitcoin. This evolution addresses the limitations of both networks - Bitcoin's transaction speed and programmability, Ethereum’s cost and scale and allows developers to build applications that settle on either chain. The unified development model promotes a decentralized future where security, accessibility, and composability can coexist across ecosystems.

Key Ideas

STARK-Powered Bitcoin Scaling: Starknet applies its zero-knowledge proof infrastructure to scale Bitcoin, expanding its utility for everyday decentralized applications.
Cross-Chain Optionality: Developers can build on Starknet and choose between Bitcoin and Ethereum for settlement, unlocking broader reach and composability.

Now it is posible to develop business models around cross-chain UX, emphasizing transparency, decentralization and financial sovereignty.
