DEVICES FOR PROVIDING A SET OF CRYPTOGRAPHICALLY SECURED AND FILTERED AND SORTED TRANSACTION DATA SETS OF A BLOCK OF A BLOCKCHAIN

摘要

The invention relates to devices for providing a set of cryptographically secured and filtered and sorted transaction data sets of a block of a blockchain and to a method for forming a set of the sorted transaction data sets. One aspect of the invention is a device for providing a set of cryptographically secured and filtered transaction data sets from a set of transaction data sets (Tx2, Tx1, Tx0, Tx3) of a block (B10, B11) of a blockchain that have been checked for integrity and semantically sorted, which block is formed in particular according to the method according to the invention, said device comprising: providing means for providing at least one such block of a blockchain and coupling means for coupling the providing means to a filtering apparatus, which determines, by means of a filter criterion, the set of filtered transaction data sets from the set of transaction data sets of the block chain that have been checked and semantically sorted, and outputting means for providing the determined set of filtered transaction data sets.
