Abstract: Described are techniques for generating and employing decentralized asset identifiers for cross-blockchain network asset transfers, the techniques including registering a decentralized asset identifier to an asset with a local asset identifier, where the decentralized asset identifier is immutable. The techniques further include endorsing a proposed transaction for transferring the asset from a first controller associated with a first blockchain network to a second controller associated with a second blockchain network, where the proposed transaction utilizes the decentralized asset identifier. The techniques further include exchanging, in a document associated with the decentralized asset identifier and retrieved from an identity network, the first controller for the second controller.

Abstract: The processor may collect, from a first peer, a first data set associated with a channel. The channel may include one or more assets associated with a first peer. The channel may link the first peer to a second peer. The processor may analyze the first data set to determine a first status for the one or more assets. The processor may provide the first status of the one or more assets in a viewable channel to the blockchain network.

Abstract: A computer-implemented method and a computer program product for enforcing verifiable mandatory access control (MAC) labels, and a data processing system. One embodiment may comprise receiving, from an entity, a first verifiable MAC label associated with an object, receiving, from the entity, a second verifiable MAC label associated with a subject requesting to access the object, and determining whether to grant, to the subject, access to the object responsive to the request based on comparing the first verifiable MAC label associated with the object and the second verifiable MAC label associated with the subject to a verifiable MAC policy. Each of the first verifiable MAC label, the second verifiable MAC label, and the verifiable MAC policy in some embodiments may be formatted as a verifiable credential that is machine readable and digitally signed.

Abstract: An example operation may include one or more of receiving a data file with off-chain content that originated in a first security domain of a multi-domain blockchain network, verifying that the on-chain and off-chain content satisfies a cross-domain security policy between the first security domain and a second security domain within the multi-domain blockchain network with a different security policy than the first security domain, in response to verifying the on-chain and off-chain content, signing the on-chain portion of the data file with a signature of a cross-domain endorsement peer, transmitting the signed on-chain portion of the data file to an ordering service of the multi-domain blockchain network, and transmitting the off-chain portion of the data file to a cross-domain content controller in the first security domain.

Abstract: Systems, methods, and computer programming products for detecting, clearing and/or separating potentially tainted digital assets entering a digital network, providing an avenue to satisfy regulatory requirements and ensure digital asset trading is uninterrupted due to the presence of tainted assets. Specialized nodes of the blockchain network intercept incoming transactions and routes the digital assets to a clearing house for analysis, processing and separation of potentially tainted assets. The clearing house uses a plurality of techniques to track, trace and analyze digital assets using techniques provided by the blockchain network or utilizing one or more service providers. Cleared assets are processed and channeled from the clearing house to the wallets or addresses designated by the transaction information and assets with high potential for being tainted are placed within a special wallet for additional clearance and regulatory scrutiny.

Abstract: A method is provided for forming a structured panel. During this method, a cellular core is formed that comprises a corrugated ribbon configured with a plurality of baffles and a plurality of septums. Each of the septums extends longitudinally between and connected to a respective adjacent pair of the baffles. At least one element of the corrugated ribbon includes a structural reinforcement. The forming includes: feeding a ribbon of material between a first roller and a second roller, corrugating the ribbon of material with the first roller and the second roller to provide the baffles and the septums, and stamping the structural reinforcement into the element with the first roller and the second roller. The cellular core is bonded to a first skin. The cellular core is bonded to a second skin. The cellular core is vertically between the first skin and the second skin, and the first skin is configured with a plurality of perforations.

Abstract: A node in a blockchain network may receive a request for information regarding a token, retrieve token information regarding the token from the blockchain network, generate based on the token information, a token connection object (TCO) for the token, wherein the TCO includes a subset of the token information, and send the TCO to a requestor.

Abstract: A processor may register one or more verifiable asset credential schemas. A verifiable asset credential schema may prescribe the format and content of asserting blockchain-backed asset state. The processor may register an issuer policy for the verifiable asset credentials. The issuer policy may be associated with a schema and intended credential holder(s). The processor may subscribe the asset credential issuer to one or more peers on the blockchain. The processor may issue commit notifications to a subscribing asset credential issuer in the form of schema-compliant committing-peer verifiable credentials. The processor may collect the committing-peer verifiable credentials from one or more peers. The processor may validate the committing-peer verifiable credentials satisfy the security policy and schema for a designated intended credential holder. The processor may issue a schema-compliant verifiable asset credential to the policy-designated credential holder(s).
