Abstract: mathsf Web3.0}$, often cited to drastically shape our lives, is ubiquitous. However, few literatures have discussed the crucial differentiators that separate ${\mathsf Web3.0}$ from the era we are currently living in. Via a thorough analysis of the recent blockchain infrastructure evolution, we capture a key invariant featuring the evolution, based on which we provide the first academic definition for ${\mathsf Web3.0}$. Our definition is not the only way of understanding ${\mathsf Web3.0}$, yet, it captures the fundamental and defining trait of ${\mathsf Web3.0}$, and meanwhile it is has two desirable properties. Under this definition, we articulate three key categories of infrastructural enablers for ${\mathsf Web3.0}$: individual smart-contract capable blockchains, federated or centralized platforms capable of publishing verifiable states, and an interoperability platform to hyperconnect those state publishers to provide a unified and connected computing platform for ${\mathsf Web3.0}$ applications. While innovations in all categories are necessary to fully enable ${\mathsf Web3.0}$, in this article, we present a design for the third enabler, i.e., the first interoperability platform, namely ${\mathsf HyperService}$, that advances the state-of-the-art by simultaneously delivers interoperability and programmability across heterogeneous blockchains and state publishers. ${\mathsf HyperService}$ is powered by two innovative designs: ${\mathsf (i)}$ a developer-facing programming framework that allows developers to build cross-chain applications in a unified programming model; and ${\mathsf (ii)}$ a secure blockchain-facing cryptography protocol that provably realizes those applications on blockchains. We implement a prototype of ${\mathsf HyperService}$ in approximately 62,000 lines of code to demonstrate its practicality, usability and scalability.
