Resumen de: CN118435225A
A system and computer-implemented method of generating recipient-facilitated blockchain transactions. The recipient device transmits the recipient outbound point to the sender device. The sender device returns a partially complete transaction that contains the recipient exit point as recipient input for the partially complete transaction and contains at least one sender input. The recipient device then adds a recipient output script as an output to the partially complete transaction, adds an unlock script for the recipient exit using digital signatures across all inputs and outputs to produce a complete transaction, and transmitting the complete transaction to a block chain node of the block chain network for propagation and inclusion in the block.

This invention is aimed at applying blockchain and NFT (Non-Fungible Tokens) technologies in a new field—the tokenization of biological objects such as humans, plants, animals, microorganisms, or biological samples, their characteristics, and properties. The technical result is the enhancement of personal data protection and property rights for biological objects, as well as the emergence of a new method for representing biological objects in digital environments. The method describes ways of identification, verification, and digitalization of these objects using blockchain and NFT technologies. The method discloses the principle of associating each biological object with a unique NFT (Non-Fungible Token), which serves as a digital certificate of identity or authenticity of ownership of the biological object. The potential application areas of this invention are diverse, including agriculture, biodiversity, pharmaceuticals, the food industry, scientific research, and virtual environments.
