Abstract: The present disclosure provides a method for hierarchically pruning data in a blockchain transaction, which comprises: acquiring a transaction data set; performing N rounds of pruning on the transaction data set based on a data pruning model to obtain a target data set; and performing processing on the target data set to obtain a target value, wherein the target value is configured as the transaction identification number used when the target data set is on-chain. Based on the customized data pruning model, part of the data in the transaction (e.g., Unlocking-Scripts and Locking-Scripts) can be easily pruned in the process of network transmission, internal storage, or construction of a new transaction (especially the Unlocking-Scripts therein) without affecting the process of verifying the data of other parts of the transaction data, which significantly improves the efficiency of UTXO-based blockchains.

Abstract: This invention provides a preparation method of a catalyst for preferential oxidization of CO in a hydrogen-enriched atmosphere, and a catalyst product obtained from the method and its applications thereof. Particularly, in this invention, a wide-temperature catalyst for preferential oxidization of CO in a hydrogen-enriched atmosphere is obtained by depositing one or more of an iron oxide, cobalt oxide, and nickel oxide as a promoter onto the surface of a supported Pt-group noble metal catalyst precursor via chemical vapor deposition or atomic layer deposition. In the wide-temperature catalyst, the active noble metal component has a content of 0.1 to 10 wt %, and the promoter has a content of 0.1 to 10 wt % in terms of the metal element thereof. In the reaction of preferential oxidation of CO in a hydrogen-enriched atmosphere, the catalyst prepared by this invention can exhibit excellent catalytic performance and can achieve high conversion of CO with high selectivity in a wide temperature range of −80 to 200° C., for example. Also, the catalyst can remain stable for a long time even in a case where steam and CO2 are present in the hydrogen-enriched atmosphere.
