Fast access to a data resource update in a blockchain network

A system, comprising:

• a memory storing multiple instructions;
• and
• one or more processors configured to execute the instructions to:
• call a special function from an application to access a state variable in a block producer, wherein the special function is configured with an identifier to authenticate a data source in a blockchain network;
• authenticate a signature of the data source to verify that the data source is a reliable data source;
• store, from the data source, a data in a low latency memory circuit in the blockchain network;
• allow a blockchain application to access the data in the low latency memory circuit using a function that has accessibility to the low latency memory circuit;
• write the data in a blockchain block when a block producer reads the data from the blockchain application;
• and
• encrypt the data prior to storing in the low latency memory circuit with a time-dependent encryption key.

A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a computer to perform a method, the method comprising:

• calling a special function from an application to access a state variable in a block producer, wherein the special function is configured with an identifier to authenticate a data source in a blockchain network;
• authenticating a signature of the data source to verify that the data source is a reliable data source;
• storing, from the data source, a data in a low latency memory circuit in the blockchain network;
• allowing a blockchain application to access the data in the low latency memory circuit using a function that has accessibility to the low latency memory circuit;
• writing the data in a blockchain block when a block producer reads the data from the blockchain application;
• and
• encrypting the data prior to storing in the low latency memory circuit with a time-dependent encryption key and providing the time-dependent encryption key to a block producer in the blockchain network.
