No doubt, the Blockchain technology, along with the adoption of cryptocurrencies, is getting bigger. The business end of the market is expected to reach $21 billion over the next five years.

Expectedly, professional services giants are now taking a larger role in tackling new challenges in the market, the Big Four firms and other leading brands are working with several crypto and blockchain firms on ways to combat interoperability, regulatory challenges and development of the technology.

Henri Arslanian, PwC’s global crypto leader, told Cointelegraph that the Big Four firms majorly have a vital role in the advancement of the cryptocurrency ecosystem, saying:“Although Bitcoin was designed with a trustless ideology, the reality is that the industry still requires trusted entities to catalyze the development of the ecosystem.

Arslanian added that when he first joined PwC years back, few people took crypto seriously. However, he saw an increasing demand for crypto assets, with some businesses starting to accept Bitcoin payments from clients.

“Over the last couple of months, we’ve expanded our work. We recently closed the first-ever crypto fundraising deal at PwC, in which we led a $14 million Series A round for a Swiss-based crypto firm with Asian family offices. We are also the auditor for BC Group, a publicly listed crypto company in Hong Kong.”

BC Group CEO, Hugh Madden, also said that BC’s vision was to make use of crypto assets in Asia’s financial market. In turn, BC Group must set standards for compliance, security, and performance. Madden buttressed on the role of audits play by saying:

“Auditing, like regulatory clarity, provides confidence to all stakeholders that companies are operating transparently and adhering to expected industry standards. As the business of digital assets continues to grow and mature, and compliance and regulatory standards become more robust, auditors will continue to play a pivotal role.

KPMG United States blockchain audit leader, Erich Braun, further contributed by saying that a business’s blockchain system should be developed with the intent to meet both accounting and operational needs to meet with accounting standards:

“SEC issuers will want to design blockchain technologies to support the entity’s internal control over financial reporting. Being able to prove how these technologies achieve their aims in a well-controlled environment is critical to a successful blockchain strategy.

If the technology is not auditable, the immense benefits it brings, such as increasing efficiencies and cutting costs, may not be realized.”Henri Arslanian, added in his closing remarks that the Big Four firms are indeed the most important players for the crypto asset space.

He said:

“I believe the Big Four firms will serve as the bridge between the crypto ecosystem and the institutional world. It is good for both the crypto ecosystem and for professional services firms like ours as a new source of clients that we can help.”
