PwC, one of the Big Four accounting firms, announced that it expanded its “Halo” suite of auditing tools to provide assurance services for entities engaging in cryptocurrency transactions. Although the press release stated that the new tool is not compatible with all cryptocurrencies, it still supports all of the major ones and helps prevent the random loss of user funds, potentially proving its utility to both corporations and consumers alike. PwC has a pending patent application directed to auditing in the cryptocurrency space, indicating its willingness to invest in IP as well. This makes them the only firm among the Big Four to have patent documents in the Cryptocurrency sector. Is this the large financial entities’ way of piloting their influence in the crypto sector before investing more into IP?
