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. ## Claims ### Claim 1 A computer-implemented method, comprising: retrieving time-dependent data from a data source communicatively coupled to a first block producer associated with a blockchain network; forming a data packet including the time-dependent data, the time-dependent data encrypted with a time-dependent encryption key; storing the data packet in a low-latency memory circuit in the blockchain network, the low-latency memory circuit comprising at least one of a random-access memory (RAM), a dynamic random-access memory (DRAM), and a static random-access memory (SRAM); providing the time-dependent encryption key to a second block producer associated with the blockchain network, wherein the first block producer and the second block producer are independent of each other; allowing the second block producer to access the time-dependent data stored in the low-latency memory circuit using the time-dependent encryption key; and writing the time-dependent data in a blockchain block when the first block producer reads the time-dependent data. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the time-dependent data includes at least one of news, weather conditions, stock market prices, sensor measurements, time stamps, and metadata. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, further comprising opening a dedicated socket in a server to receive the time-dependent data from the data source. ### Claim 4 (depends on 3) The computer-implemented method of claim 3, wherein the dedicated socket includes a dedicated port in a communications module of the server, wherein the server is communicatively coupled to the blockchain network. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein storing the time-dependent data in the low-latency memory circuit in the blockchain network comprises storing the time-dependent data in a dedicated memory space in a server. ### Claim 6 (depends on 1) The computer-implemented method of claim 1, wherein each of the first block producer and the second block producer includes a virtual machine running a blockchain application, wherein the blockchain application is operated through an action port communicating a server with a remote server providing a smart contract to the first block producer or the second block producer. ### Claim 7 (depends on 1) The computer-implemented method of claim 1, further comprising receiving an update of the time-dependent data from the data source in a dedicated socket before writing the time-dependent data in the blockchain block. ### Claim 8 (depends on 1) The computer-implemented method of claim 1, further comprising storing an updated value of the time-dependent data and a metadata associated with the updated value in an actions log and writing the actions log in a blockchain database. ### Claim 9 (depends on 1) The computer-implemented method of claim 1, wherein writing the time-dependent data in the blockchain block comprises irreversibly encrypting the time-dependent data in the blockchain block. ### Claim 10 (depends on 1) The computer-implemented method of claim 1, further comprising replaying a blockchain application to retrieve an updated value of the time-dependent data. ### Claim 11 A system, comprising: a memory storing multiple instructions;
