A method for tolerating Byzantine faults in a many core system-on-chip (SOC). Each processing element on the SOC is controlled by a respective consensus module. Each consensus module receives instructions from an SOC controller and after running a practical Byzantine fault tolerance consensus algorithm with other consensus modules, sends instruction to respective processing element. After running instructions by processing elements, each respective consensus module stores respective execution results in a respective blockchain. Each consensus module calculates a Merkle tree root from respective blockchain and send it to an arbiter module installed on the SOC. The arbiter module identifies faulty processing elements based on receive Merkle tree roots and send identification numbers of faulty processing elements to the SOC controller. The SOC controller switches off all faulty elements and their consensus modules. Each live consensus module purges respective blockchain.

Systems and methods for blockchain-based asset authentication are described. The disclosed embodiments leverage the traceability and immutability of blockchains (or distributed ledgers, in general) to enable the authentication and ownership of assets, e.g., luxury goods. In an example, this is achieved by first pairing an authentication chip with a physical product, and writing a transaction correlated with the first pairing to a blockchain. The product being acquired (reacquired) results in the blockchain being updated (e.g., an updated transaction being written to the blockchain) and the (subsequent) owner being provided with a digital passport that can be added to the owner's digital Web3 wallet. The described embodiments advantageously enable digital identities to be associated with physical goods, which adds value for customers making a long-term investment in a luxury good, and promotes sustainability and transparency in manufacturing and retail processes.

The present invention relates to a method to create and manage a unique virtual identity, called ID-token, for a user. The ID-token enables user status verification across different virtual environments managed by different operators where the user has diverse identifiers. A trusted party receives and verifies personal identity data, selects parameters, and calculates the ID-token, which serves as proof of identity ownership and includes metadata for status verification. The ID-token is linked to a unique identifier and a smart contract. The ID-token and its smart contract are recorded on a blockchain accessible to virtual environment operators, with calculation data securely transferred to the user. Operators manage a banishment list of banished ID-tokens and validate registration requests by verifying the presence of ID-token in banishment list.

Methods, systems, and devices for data management are described. A custodial token platform may receive a request, from a client application on a user device, to generate an attestation record associated with a user profile of the custodial token platform. The custodial token platform may verify, after receiving the request, that the user profile is associated with the set of attributes for the requested attestation record. The custodial token platform may broadcast, after verifying that the user profile is associated with the set of attributes, a first message configured to generate the attestation record via a blockchain network, where the first message is signed using a key associated with the custodial token platform. The custodial token platform may broadcast a second message configured to store a mapping of an identifier for the attestation record and a self-custody blockchain address associated with the user profile.
