The invention discloses a block chain data comparison and consensus method used for hash value calculation of content of each transaction. By changing the random numbers, the numbers of some bits of the hash values are set not to be repeated in a time period, and can be called as unrepeated serial numbers. Accounting servers are used to compare the numbers of the preset bits of the hash values to determine whether the transactions are identical or not. The unrepeated serial number comparison can be carried out in a way of establishing the Merkle-like tree, and because the numbers of the preset bits of the hash values of the transactions are not repeated, and can be used as the serial numbers, and can be disposed in the Merkle-like tree according to the certain rule, and therefore for different accounting servers, the positions of the hash values of the same transaction on the Merkle trees are totally identical, and the differences can be found out quickly, the data transfer amount can be reduced, and the time required by the consensus can be greatly accelerated.

The present invention provides systems and methods for obtaining information from a networked system utilizing a distributed web crawler. The distributed nature of clients of a server is leveraged to provide fast and accurate web crawling data.

Techniques for a post-write read are presented. In an exemplary embodiment, host data is initially written into the non-volatile memory in binary form, such as a non-volatile binary cache. It is then subsequently written from the binary section into a multi-state non-volatile section of the memory. After being written in multi-state format, pages of data from a multi-state block can then be checked against there source pages in the binary section to verify the quality of the multi-state write. This process can be performed on the memory device itself, without transferring the pages out to the controller.
