4 years! Indeed, Starknet is built from first principles: ZK-STARKs, Cairo, Native AA, decentralization. We design Starknet with long-term vision in mind: We make innovative choices because they are the right building blocks that will help us to solve today's challenges, as well as the challenges we'll face in 1, 5, 10, and 50 years from now. We make sure Starknet is built with the right elements for when throughput surges, when non-technical people want to use DeFi, for when TradFi leans into crypto, and when the entire crypto ecosystem reaches true mass adoption. We don’t take shortcuts. Scale, security, UX, privacy, self-custody, freedom - that's Starknet.
