摘要： A physical card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. The physical card may include disposed thereon a single address operable to receive digital bearer assets in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Other decentralized computing platforms utilize different address generation protocols, thus preventing use of a single address on those other platforms. A set of addresses is generated, each address corresponding to a given decentralized computing platform. Each address is based on a same underlying key-pair, and a primary address is selected from the set for a given card. The remaining addresses in the set are stored, without storage of the public key or private key, and returned in a response to a request for additional addresses of the currency card.

摘要： A physical currency card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. Public access information, like a cryptographic hash address operable to receive digital bearer assets or a public key operable to derive a cryptographic hash address operable to receive digital bearer access, may be visible upon inspection of the card such digital bearer assets may be transferred to the card in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Private access information, like a secret, private key that corresponds to the public key (e.g., a public-private key-pair) or a representation of the private key (like a ciphertext thereof) and corresponding encryption key, is physically concealed with tamper-evident components such that a user can readily determine whether the private access information was divulged.

摘要： An instance of a physical product includes a verification code and a unique identifier disposed thereupon by which authenticity or condition of the instance may be determined. The combination may be uniquely associated with the instance and stored, by the issuer or manufacturer for each authentic instance, locally or within a decentralized computing system having an immutable data store. The verification code may be concealed by a tamper-evident component such that access of the verification code is evident upon visual inspection. Verification may require revealing of the verification code with tamper-evidence and submission of a request including the verification code and the unique identifier (or representation thereof) to receive a verification result. Each request to verify an instance may be recorded and returned with a next request for verification of the same instance of the product to indicate whether another entity has already performed a verification.
