New generation technology that helps identify higher risk transactions and process inefficiencies. PwC has started leveraging its new Halo solution to support audits of clients engaged in cryptocurrency activities. We are also working with companies, for whom we are not the auditor, to help them address the new opportunities and challenges of blockchain and cryptocurrency, including helping them to implement the processes and controls they will require in order to obtain assurance reports from their auditors. Our ability to audit an entity engaged in cryptocurrency activities is very much influenced by our client’s control environment, and at this stage, by the breadth of tokens supported by our Halo software. These considerations will be key when determining whether we are comfortable to accept an audit engagement. PwC can currently use this tool to provide assurance services to clients transacting in Bitcoin, Bitcoin Cash, Bitcoin Gold, Bitcoin Diamond, LiteCoin, Ethereum, ERC20 - OAX token, and Ripple (XRP).
