Abstract: A frontend client system and associated frontend method perform processes for backing up encrypted data in backend storage, such that a frontend client can perform the backup without exposing the encrypted data, using the client-controlled keys, and without long running server-side processes.

Abstract: A Turing incomplete smart contracting source code for use in a blockchain network is disclosed that allows for static analysis of a smart contract at the time of publishing.

Abstract: An improved blockchain implementation that reduces application transaction processing bottlenecks for applications that operate on a decentralized network is described herein. For example, if an application operating on a decentralized network becomes sufficiently popular, an existing blockchain can be split into the original blockchain and an application-specific chain (or app chain) that includes blocks that only store transactions for the sufficiently popular application. Multiple application-specific chains can be formed as different applications become sufficiently popular. The original blockchain may be used to perform sortitions to select which miners should mine new blocks in the application-specific chain(s).

Abstract: In a decentralized system based on a blockchain, a storage server directs the off-chain storage of shared data for multiple decentralized applications in data caches on a backend storage provider, such that a user's client and any authorized decentralized applications can access encrypted data in the data caches, but the storage server performs no encryption of that data and is not exposed to encryption keys and unauthorized decentralized applications cannot access the encrypted data.

Abstract: In a decentralized system based on a blockchain, a system and method automates the process for migrating data for decentralized applications stored off-chain between backend storage providers, such as cloud-based storage providers, such that a frontend client can perform migration processes without exposing encrypted data, using client-controlled keys, and without long running server-side processes.

Abstract: A decentralized application platform and associated method creates an ID that can be used to sign into any decentralized application that follows the platform protocol without having a centralized third party having to vouch for the user's identity.
