Toshiba had two patents in blockchain during Q4 2023. Toshiba Corp filed a patent for a method of storing data using a distributed ledger on a network of computer nodes with a mesh-based architecture. The method involves receiving data from sources, updating the ledger with the data using a distributed acyclic graph (DAG), and communicating the transaction to other nodes in the network.

Application: Methods and systems for storing data using a distributed ledger (Patent ID: US20230334040A1)
The patent filed by Toshiba Corp. describes a computer-implemented method for storing data using a distributed ledger maintained across a network of computer nodes with a mesh-based architecture. The method involves receiving data from various sources, updating the ledger using a distributed acyclic graph (DAG), and communicating transactions to other nodes in the network. The communication process involves publishing messages to group addresses and utilizing mechanisms like flooding and consensus requests for updating the ledger.
The method also includes provisions for solidification requests, where nodes request information about earlier transactions, and consensus requests to gather opinions on the current state of the DAG. The patent outlines processes for joining the network, encrypting data for privacy, and establishing smart contracts for sharing decryption keys. The data being stored can include sensor data from sensors like optical or acoustic sensors. Additionally, the patent covers the configuration of computing devices, networks of computing devices, and computer-readable storage mediums to carry out the described method efficiently and securely.
