Is Buffett eyeing blockchain domain name patents? Increased holdings of nearly 30 million magnesium and became the largest shareholder of VeriSign

According to the filing submitted to the U.S. Securities and Exchange Commission (SEC) by Berkshire Hathaway last week, Berkshire Hathaway Company spent $28.55 million to buy 143,424 shares of VeriSign stock in three trading days on December 20, 23, and 24. Through the above acquisition, Berkshire Hathaway currently holds approximately 13,193,349 shares of VeriSign, with a shareholding ratio of 13.7%, becoming the largest single shareholder of VeriSign. VeriSign, founded in 1995, is a global leading provider of critical internet infrastructure and domain name registration services, realizing the navigation of the internet for many of the most recognizable domain names globally. VeriSign has achieved the security, stability, and flexibility of the critical internet infrastructure and services, including providing root zone maintainer services, operating two of the 13 global internet root servers, and providing registration services and authoritative solutions for the .com and .net top-level domains that support the majority of global e-commerce. Why is Berkshire Hathaway interested in VeriSign? Berkshire Hathaway has sold a large number of shares this year and holds a large amount of cash reserves, but the company is willing to spend a lot of money to buy VeriSign shares, which has attracted attention. Buffett and his investment team seem to see the long-term value of VeriSign, believing that VeriSign plays an irreplaceable role in the global internet infrastructure and still has significant appreciation potential. According to Marketwatch, one of the reasons Buffett is interested in VeriSign may be that VeriSign ranks high among the S&P 500 index constituent companies in various profitability indicators. In the third quarter of this year, VeriSign's gross profit margin reached 88.02%, ranking 11th among the S&P 500 index constituent companies, its operating profit margin of 71.25% ranked 6th, and its net profit margin of 51.54% ranked 7th. Holding multiple Blockchain patents It is worth noting that VeriSign has previously been granted by the U.S. Patent and Trademark Office (USPTO) multiple patents for applying Blockchain technology to domain names. Buffett may also see the development prospects of Blockchain technology as another important reason for choosing to invest in VeriSign. For example, VeriSign has obtained a patent called "Transferring Domain Names in a Secondary Blockchain Market and DNS", which describes a method that can simultaneously transfer domain names in the DNS and Blockchain network when using cryptocurrency transactions, and the method can handle the entire transaction process, including storing the cryptocurrency in a third-party escrow until the transaction is completed. Another patent, called "Lifecycle Management of Domain Name Blockchain Addresses", describes a method of linking a domain name (such as example.com) to a Blockchain wallet address, so that after the user associates the domain name with the wallet address, others can directly send cryptocurrency or other assets to the user through the domain name, without using the difficult-to-remember wallet address. This concept is not entirely new, but VeriSign's patent covers a wide range of activities related to the domain name lifecycle, rather than just manually connecting or disconnecting domain names and Blockchain addresses.
