Abstract With this invention, a computer-implemented system and method are provided for managing lifecycle events associated with blockchain-based entity compliance credentials. A compliance credential issued to an entity is recorded on a distributed ledger and associated with regulatory compliance metadata. A lifecycle management module monitors the validity of the credential and records lifecycle events including issuance, expiration, renewal, and revocation. The system updates the credential status in response to lifecycle events and enables participating platforms to determine whether the credential remains valid for participation in regulated offerings.

A satellite receives, from a ground station, multiple first commands out-or-order for replicating a conflict-free replicated dataset at the satellite. An authority to access the conflict-free replicated dataset is retrievable from a block of a blockchain. The multiple first commands are reordered based on an ordering specified by a causal tree received from the ground station. A global state of the conflict-free replicated dataset is replicated locally at the satellite based on the multiple first commands reordered in accordance with the causal tree. From the ground station, multiple second commands are received for performing operations on the conflict-free replicated dataset. The operations are performed on the conflict-free replicated dataset, using the multiple second commands, based on the authority retrieved from the blockchain.

0000 This invention relates to an improved method and system for authenticating the travel path of an object using a distributed asynchronous system incorporating blockchain technology and encrypted codes. The system utilizes digitally secured tags containing encrypted logistical data. These tags are physically and digitally associated with the product prior to entering the supply chain. Gateways equipped with artificial intelligence are strategically placed throughout the transportation route, each gateway receiving inputs from any number and type of sensors placed throughout the gateway's physical location. These gateways continuously collect data from their environment and utilize artificial intelligence to create dynamic environmental profiles. These profiles, encapsulated within a cryptographic key, are immutably recorded onto the blockchain ledger associated with the tag device physically associated to a shipment. The distinctive feature of this innovation assures an unalterable record of each shipment's journey, enhancing security, promoting transparency, and enabling swift transmission—and verification—of shipment data.

The illustrative embodiments provide a data platform, system and method for utilizing carbon credits through blockchain-based tokenization. The platform receives carbon utilization data corresponding to at least one carbon credit and executes a smart contract on a blockchain network based on the received data. Execution of the smart contract generates one or more blockchain tokens that embed metadata including a hash of the carbon utilization data and a unique security identifier. The platform performs electronic transactions for the tokens by propagating transactions for distributed consensus, verifying token authenticity through comparisons with distributed-ledger records, or generating immutable electronic records indicating tracking information for the carbon credit. Records of the electronic transactions are stored in a distributed ledger as immutable entries linking token activity to corresponding carbon utilization data.

A public key may be recorded on the blockchain by a certificate authority in such a manner that any third party may quickly and easily verify that the public key is certified by the certificate authority and that the certification has not been revoked. The certificate authority may be able to revoke the certification nearly instantaneously, and/or may be able to simultaneously certify a new key for the same entity while revoking the old key. The verification may be incorporated into a new transaction so that there is no gap between reliance on the certificate and the verification of its validity. In some cases, each transaction in which the certificate is used may also serve as linked certificate transaction that renews the certificate to enable a subsequent use.
