Xerox has won a patent for a technology that will allow the creation of digital evidence for documents and other types of data using the blockchain.

The corresponding document was published on November 13 on the website of the United States Patent and Trademark Office (USPTO).

In the description of the patent, the method of using the blockchain technology for data binding (authorship of images or videos) to a specific period of time is presented. Both open and private versions of the blockchain can be used.

According to the authors of the patent, the technology can be used to audit generated files in such areas as finance and medicine, tax reporting and education. Scope of criminal investigations is also mentioned, including the records of interrogations of suspects, photographs from crime scenes, and the results of DNA tests, the protection of which from possible falsification is of great importance.

The application was filed in August 2017 and had a common name with another Xerox patent application of 2015 and did not contain any mention of the blockchain.

Bitcoin SV Blockchain to Undergo Reorganization

This happened due to the fact that some blocks were rejected by Bitcoin SV blockchain

Several blocks were rejected by the Bitcoin SV network after the addition, which caused the re-organization in the blockchain's history.

Almost each time someone is trying to produce a very large block on the BSV chain, there’s a reorg. Just an hour ago our Blockchair engine has witnessed a 3-block reorg (I think that's a record)! Blocks #578640–578642 got orphaned by a longer chain because they were too big

The large blocks, about which Zhavoronkov writes, are no longer displayed by the blockchain browser, since they are not part of the main chain in which they were located until a certain moment, until they were replaced by another chain, which eventually became dominant.

This is basically exactly the problem the BU gigabock testnet identified. At sizes > 100mb the mempools were so out of sync that blocks were basically transmitted as full blocks.

BSV had ONE 128mb block and it caused a six block reorg. On the BU testnet sustained 128mb blocks caused a total breakdown of the chain where there were so many reorgs that every node had a different view of the state of the blockchain.

Thus, Chris assumes that the problem is caused not by the malicious actions of the network members, but by its functional bug. 

This update is noticeable in the background of recent Bitcoin SV delisting campaign, which was started by the number of big exchanges as a reply to lawsuit by Craig Wright, BSV supporter, against anonymous critic.
