Abstract: A method for providing a language agnostic contract execution on a blockchain is provided. The method includes providing a menu comprising multiple execution environments, and selecting, from a suite of virtual machine containers, a virtual machine container that runs an execution environment selected by the developer of the blockchain application. The method also includes enabling one or more functions in the virtual machine container to access a dedicated memory or a state variable in the block producer to run an action in the virtual machine container, the action provided by a server running the blockchain application, providing the action to the blockchain application in the virtual machine container, and writing an output from the action of the blockchain application to a secure ledger in a blockchain. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also provided.

Abstract: A method for fast access to a data resource in a blockchain network is provided. The method includes opening a dedicated socket in a server to receive a datum from a data source and authenticating a signature of the data source to verify that the data source is a reliable data source. The method also includes storing the data in a dedicated memory space in the server, allowing a blockchain application to access the data in the dedicated memory space using a function that has accessibility to the dedicated memory space, and writing the data in a blockchain block when a block producer reads the data from the blockchain application. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also provided.

Abstract: A method for storing time-sensitive secrets in a network is provided. The method includes receiving a first encryption key from multiple encryption keys, the multiple encryption keys associated with a first time window and accessing a data packet encoded according to the encryption keys. The method also includes writing a decrypted data packet to a block in a blockchain when the first encryption key matches a first time-sensitive value, and writing the decrypted data packet to the block in the blockchain when a second encryption key, received from the content provider, matches a second time-sensitive value after the first time-sensitive value has lapsed, wherein the first time-sensitive value and the second time-sensitive value are a non-overlapping time sequence in the first time window. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also provided.

Abstract: Methods and systems for creating a digital association are provided. The method includes obtaining a first user-generated item comprising identifiable features of a first user and a second user. The method also includes obtaining a second user-generated item comprising the identifiable features of the first user and the second user. The method also includes cross-confirming that the first and second user-generated items are valid to verify the digital association.

Abstract: Methods and systems for creating a verifiable digital identity are provided. The method includes obtaining a first user-generated item comprising an identifiable feature. The method also includes digitally signing the first user-generated item to generate a secure digital artifact. The method also includes uploading the secure digital artifact and the first user-generated item to an auditable chain of a public ledger. The method also includes verifying a digital identity of the user by auditing the auditable chain. The method also includes obtaining a second user-generated item generated comprising the identifiable feature. The method also includes comparing the first and second user-generated items. The method also includes uploading the second user-generated item to the public ledger when the comparing is within a threshold.
