Abstract: Systems, apparatuses, methods, and computer program products are disclosed for tracking NFT-backed instruments. An example method includes identifying a plurality of NFTs on a distributed blockchain ledger, associating an instrument with the cryptographic NFTs, determining a value of the cryptographic NFTs based on transactions on the distributed blockchain ledger that are associated with one or more of the cryptographic NFTs, monitoring the distributed blockchain ledger to detect transaction data of a block of the distributed blockchain ledger, the transaction data indicative of a transaction associated with a first cryptographic NFT of the cryptographic NFTs, determining a modified value of the cryptographic NFTs responsive to the transaction data, and terminating the instrument associated with the cryptographic NFTs in response to a comparison of the modified value to a predetermined threshold value indicating that the modified value is less than the predetermined threshold value.

Abstract: Systems, methods, and computer program products are disclosed for issuing one or more blockchain tokens for property rights. An example method includes receiving an indication of user input including attributes of a property and, and generating a primary blockchain token, where the primary blockchain token includes metadata that correspond to the attributes of the property. The example method further includes broadcasting, over a blockchain network, a transfer of the primary blockchain token to the primary party, and generating one or more secondary blockchain tokens, where each of the one or more secondary blockchain tokens includes respective secondary metadata that correspond to unique subdivided property rights regarding the property, where the secondary metadata include a link to the primary blockchain token. The example method further includes broadcasting, over the blockchain network, transfer of the one or more secondary blockchain tokens to one or more secondary parties.

Abstract: A direct injection fuel system is shown for injecting hydrogen fuel into a gas turbine combustor. The fuel injection system includes a plurality of fuel injector blocks. Each fuel injector block includes a fuel admission duct having an inlet for receiving hydrogen fuel from a fuel supply, an outlet for delivering hydrogen fuel into the combustor and a central axis extending from said inlet to said outlet. Each fuel injector block also includes an air admission duct located around the periphery of the fuel admission duct, having an inlet for receiving air from a diffuser and an outlet for delivering air into the combustor for mixing with the hydrogen fuel.

Abstract: A direct fuel injection system (206) is shown for injecting hydrogen fuel into a gas turbine combustor, the fuel injection system comprising a plurality of fuel injector blocks (1202). Each fuel injector block includes one or more air admission ducts (1603) for receiving air from a diffuser and an air outlet for delivering air into a mixing zone for combustion with fuel. Each fuel injector block also includes a fuel admission duct or aperture having a fuel inlet for receiving fuel (F) from a manifold, and a fuel outlet for delivering fuel into the mixing zone.
