Language agnostic smart contract execution on a blockchain

A system for smart contract execution on a blockchain, comprising:

• a memory configured to store instructions;
• and
• one or more hardware processors configured to execute the instructions to cause the system to:
• provide, to a developer of a blockchain application accessed by a block producer, a menu comprising a list of multiple execution environments that includes at least different versions of a same execution environment, wherein the blockchain application is hosted by a server as an immutable register or a smart contract in a suite of virtual machine containers in the execution environments within the block producer in the server;
• select, from the suite of virtual machine containers, a virtual machine container that runs an execution environment selected by the developer of the blockchain application from the menu;
• enable 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 the server running the blockchain application to allow the server to access the dedicated memory or the state variable from the one or more functions of the blockchain application executable in the virtual machine container provided by the server;
• provide the action to the blockchain application in the virtual machine container;
• prevent access to the blockchain application with a security feature in an associated virtual machine container;
• and
• write an output from the action of the blockchain application to a secure ledger in a blockchain, wherein providing the menu comprising the list of multiple execution environments comprises providing the menu including at least one of Javascript Virtual Machine, native, and C++ execution environments.

A non-transitory, computer-readable storage medium storing instructions which, when executed by a hardware processor, cause a computer to perform a method for smart contract execution on a blockchain, the method comprising:

• providing, to a developer of a blockchain application accessed by a block producer, a menu comprising a list of multiple execution environments that includes at least different versions of a same execution environment, wherein the blockchain application is hosted by a server as an immutable register or a smart contract in a suite of virtual machine containers in the execution environments within the block producer in the server;
• selecting, from the suite of virtual machine containers, a virtual machine container that runs an execution environment selected by the developer of the blockchain application from the menu;
• 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 the server running the blockchain application for allowing the server to access the dedicated memory or the state variable from the one or more functions of the blockchain application executable in the virtual machine container provided by the server;
• providing the action to the blockchain application in the virtual machine container;
• preventing access to the blockchain application with a security feature in an associated virtual machine container;
• and
• writing an output from the action of the blockchain application to a secure ledger in a blockchain, wherein:
• providing the menu comprising a list of the execution environments comprises providing the menu including at least one of a javascript virtual machine, native, and C++ execution environments, and
• providing the menu comprising a list of the execution environments comprises providing the menu including one or more versions of the same execution environment.
