Centralized trust is ubiquitous in today's interconnected world, from computational resources to data storage and its underlying infrastructure. The monopolization of cloud computing resembles a feudalistic system, causing a loss of privacy and data ownership. Cloud Computing and the Internet in general face widely recognized challenges, such as (1) the centralization of trust in auxiliary systems (e.g., centralized cloud providers), (2) the seamless and permissionless interoperability of fragmented ecosystems and (2) the effectiveness, verifiability, and confidentiality of the computation. Acurast is a decentralized serverless cloud that addresses all these shortcomings, following the call for a global-scale cloud founded on the principles of the open-source movement. In Acurast, a purpose-built orchestrator, a reputation engine, and an attestation service are enshrined in the consensus layer. Developers can off-load their computations and verify executions cryptographically. Furthermore, Acurast offers a modular execution layer, taking advantage of secure hardware and trusted execution environments, removing the trust required in third parties, and reducing them to cryptographic hardness assumptions. With this modular architecture, Acurast serves as a decentralized and serverless cloud, allowing confidential and verifiable compute backed by the hardware of security and performance mobile devices.
