Title: BLOCK CHAIN FOR SUPPORTING PLURALITY OF ONE-WAY FUNCTIONS FOR VERIFICATION OF BLOCKS
Abstract:
The present specification discloses a method for generating a block by a node device, comprising the steps of: obtaining one or more transactions that are not stored in a block chain; determining whether a new hash function for the one or more transactions is needed; preparing the new hash function; generating block data for the one or more transactions; calculating a hash value for the block data by the new hash function; generating a block including the hash value and the block data; and transmitting the block for storage in the block chain.
