Abstract: A processing method includes acquiring, by a first service node of a first blockchain, a cross-chain transfer request, the cross-chain transfer request including a virtual resource value, a first resource transfer-out address on the first blockchain, and a first resource transfer-in address on a second blockchain. The cross-chain transfer request is used by a second service node of the second blockchain to lock a first virtual resource of the virtual resource value in the second blockchain. The method further includes performing resource transfer-out processing on a second virtual resource associated with the virtual resource value in the first resource transfer-out address in response to a determination that the second service node locked the first virtual resource successfully. The method further includes transferring the first virtual resource to the first resource transfer-in address in the second blockchain in response to a determination that the second virtual resource was transferred out.

Abstract: A data processing method performed by a first device includes: generating, in response to first service data satisfying a data uploading condition, a first bit array corresponding to the first service data; encrypting the first bit array through a data key to obtain a ciphertext bit array, the data key being generated by a second device in a data intersection application run in a trusted execution environment of the second device; and transmitting the ciphertext bit array to a blockchain node for forwarding to a second device, for the second device to decrypt, in the data intersection application through the data key, the ciphertext bit array to obtain the first bit array.

Abstract: The present invention provides for a method to deconstruct a biomass: the method comprising: (a) introducing a solvent comprising a polyamine, or a mixture of polyamines, to a biomass to dissolve at least part of solid biomass in the solvent, wherein the polyamine is a Brønsted or Lewis base, and/or the polyamine is a hydrogen bond donor and/or acceptor; (b) optionally introducing an enzyme and/or a microbe to the solubilized biomass mixture such that the enzyme and/or microbe produces a sugar from the solubilized biomass mixture; (c) optionally separating the sugar from the solubilized biomass mixture; and (d) optionally separating the lignan from the solubilized biomass mixture.
