  • Publication number: 20190265894
    Abstract: In a mechanism for deleting blocks from a blockchain, a retention period (T), a minimum number of blocks (L), and a hash of the oldest block are defined. A participant node creates the new block including a block header. The participant node determines whether a timestamp in an oldest block in the blockchain is older than a current time plus T, and whether a current number of blocks in the blockchain is greater than or equal to L. When both are true, the participant node deletes an oldest block in the blockchain. The participant node adds a hash of an oldest remaining block and an original number of blocks of the blockchain to the block header of the new block. The participant node broadcasts a message announcing the new block to remaining participant nodes of the plurality of participant nodes.

  • Publication number: 20190266128
    Abstract: A blockchain processing method and system for verification of deleted data for blockchains. An item of data is deleted from a block of a blockchain by: identifying the block of the blockchain storing the item of data; deleting the item of data from the identified block without deleting a hash value associated with the deleted item of data from the identified block; and adding metadata to a new block of the blockchain identifying the deleted item of data. The metadata includes a block identifier (ID) of the identified block as a location of the deleted item of data as well as the hash value associated with the deleted item of data. The block ID may comprise a root hash in a block header of the identified block, a universally unique identifier (UUID) allocated to the identified block, or an offset from the new block to the identified block.

  • Patent number: 10394620
    Abstract: A technique of operating a system is provided that processes data with one or more data processing modules provided in parallel. A synchronization token is input into at least one data processing module that is in an operational state from the one or more data processing modules provided in parallel, in response to a request to change allocation of the data. The allocation of the data is changed to the one or more data processing modules provided in parallel, after the synchronization token is input. In response to the synchronization token having arrived at a data processing module at a later stage, the at least one data processing module, that stopped the processing, starts processing data after the synchronization token is input to the at least one data processing module.

  • Publication number: 20180245145
    Abstract: Disclosed is a nucleic acid amplification method. The method comprises: performing a first nucleic acid amplification using a target nucleic acid contained in a sample as a template; and performing a second nucleic acid amplification using the amplification product produced in the first nucleic acid amplification step as a template. In the first nucleic acid amplification, a DNA polymerase that selectively amplifies a nucleic acid not comprising a uracil base is used to produce an amplification product that does not comprise a uracil base. In the second nucleic acid amplification, (i) dUTP and/or a primer comprising a uracil base, and (ii) a DNA polymerase capable of amplifying a nucleic acid comprising a uracil base are used to produce an amplification product that comprises a uracil base.
