How the 4 largest audit companies are delving into the blockchain industry?

Almost all cryptocurrencies run on blockchain. This infrastructure is the basis of various advantages such as security and decentralization offered by cryptocurrencies. Therefore, it is necessary to examine the development of the cryptocurrency market, especially Bitcoin, not only on price but also in regard to the infrastructure it has. Because the most important feature of an investment instrument is the reliability of the investment. Therefore, trust in cryptocurrencies is directly proportional to the trust in blockchain. The less question marks about the security of blockchain technology around the world remain and the more widespread this infrastructure becomes, the more positive cryptocurrencies are expected to be affected.

In order for blockchain technology to be accepted internationally and in various fields and to reach a significant financial size, it is key to integrate it with commercial and public institutions. 4 major auditing companies; Ernst & Young, PwC, Deloitte and KPMG, can be considered as an ideal distribution network in the sense that this integration reaches out to almost every organization. For this reason, this article was written to explain the role of 4 major audit companies regarding the development of cryptocurrencies.

In articles below, it can be seen what kind of services these companies provide in which fields.

KPMG offers blockchain and cryptocurrency services individually. Customers who are interested in blockchain technology can get support from KPMG at every step of the integration process of this technology. KPMG first determines whether the client’s company is in need of blockchain. However, companies can also get support from KPMG on issues such as installation, selecting algorithm and operation of the system. Currently, KPMG has a supply chain system set up on blockchain for the pharmaceutical industry.

Regarding the field of cryptocurrency, KPMG informs its customers about the risks of cryptocurrencies. It can be said that the company has a more skeptical approach in this sense. Security levels of cryptocurrencies other than Bitcoin can be controversial despite the blockchain system. KPMG’s most recent breakthrough in this field is the system called Chain Fusion. This product, launched in 2020, gathers customers’ cryptocurrency and digital assets under a single roof. Customers can integrate their cryptocurrency wallets and track their transactions with Chain Fusion, which also offers custody services. In this way, KPMG combines wallets and cryptocurrencies with their own blockchain networks under one roof.

KPMG executive Sam Wyner announced that they have a high demand from US customers, especially after the cryptocurrency-friendly regulations implemented by the US Banking Authority OCC. Sam Wyner also stated that he expects the interest in cryptocurrencies to increase in both individual and corporate level as the CBDC (Central Bank Digital Currency) trend becomes widespread.
