Various aspects of the subject technology relate to systems, methods, and machine-readable media for providing an application trusted execution environment. Various aspects may include performing attestation of each application enclave of a plurality of application enclaves for a plurality of applications. Aspects may also include receiving a request from a client. Aspects may also include selecting a load balancer to forward the request to the application enclaves. Aspects may also include determining a sensitivity level of the request that is associated with a secured environment parameter. Aspects may include routing, by an enclave server of the load balancer, the request to an application enclave according to the sensitivity level for execution of an application of the plurality of applications in the application trusted execution environment.

Scaled trusted execution environment for application services

Various aspects of the subject technology relate to systems, methods, and machine-readable media for cross-chain communication in a blockchain platform. Various aspects may include accepting, at a first blockchain, a first transaction including a message and a message payload. Aspects may also include validating, at the first blockchain, the message by signing the message using signature keys of one or more validators in a first set of validators of the first blockchain. Aspects may also include generating an aggregate signature based on the signature keys of the one or more validators in a first set of validators. Aspects may also include submitting a second transaction on to a second blockchain, the second transaction including the message and the aggregate signature. Aspects may include validating, at the second blockchain, the second transaction based on a shared registry.

Authenticated cross-subnet communication

A method for blockchain management includes receiving a first definition for a custom blockchain on a blockchain platform, the first definition including definitions for default data structures. The method further includes initializing a virtual machine and configuring the virtual machine using the first definition. The method further includes receiving a second definition for the custom blockchain, the second definition including definitions for user-defined data structures. The method further includes further configuring the virtual machine using the second definition and executing the custom blockchain on the virtual machine.

Framework for high performance blockchains

Various aspects of the subject technology relate to systems, methods, and machine-readable media for enhancing liveness in a blockchain. Various aspects may include running a first consensus protocol. Aspects may also include detecting a liveness attack in the first consensus protocol. Aspects may also include suspending, when the liveness attack is detected, acceptance of new blocks in the first consensus protocol. Aspects may also include broadcasting a preferred block and identifying a highest accepted block in the set of nodes from running the first consensus protocol based on the preferred block. Aspects may also include transitioning from the first consensus protocol to the second consensus protocol and running the second consensus protocol until a consensus value or a new accepted block is decided. Aspects may also include reinstating and resuming running the first consensus protocol based on the new accepted block.

Liveness in consensus protocol

Various aspects of the subject technology relate to systems, methods, and machine-readable media for managing and indexing content in a blockchain platform. Various aspects may include receiving, at the blockchain platform, content-addressable data. Aspects may also include indexing the content-addressable data. Aspects may also include generating and serving a recommendation including the content-addressable data for one or more users based on user preferences. Aspects may also include receiving an interaction from the one or more users based on the recommendation. Aspects may include updating a state of a blockchain on the blockchain platform based on the interaction.
