- Better authentication of individuals partaking in the sharing economy: Leveraging the "smart identity" functionality of the blockchain, peer-to-peer sharing businesses sites (e.g. Airbnb) can give both the customer (e.g. the renter) and the supplier (e.g. the home owner) greater assurance that the customer is really who they say they are. The GS report also links the identity to smart contracts that facilitates automated performance based payments
- Accounting system for renewable energy power generation: Where individual homeowners are generating wind or solar power, the blockchain can be the natural accounting system to manage the "debits and credits" transferred back and forth between the energy producer and the network. It also enables payment transfers as well.
- Reducing back end administration for title insurance: The actual GS report notes how the vast majority of the cost associated with title insurance can be reduced by about 30% using blockchain to manage the underlying property records. Other interesting notes is that they attribute part of the decline to improved actuarial risk calculations due to "greater historical transparency".
- Improving accuracy and timeliness of trading various securities: The financial services industry usage of the blockchain is quite straightforward - replace the chaotic world of spreadsheet accounting with the streamlined world of blockchain - it is a database technology after all. NASDAQ use of Linq was featured in this DUPress article and can also be found here. The GS report goes into much more granular detail as to the different scenarios on how the back-end system can be improved resulting in less verification issues and improved trading times.
- Better authentication of customers aka KYC (Know-Your-Customer): As noted in the BI article, "Like with the Airbnb example, Goldman envisions identity data stored on a blockchain that could help finance firms easily and quickly check new customers as part of "know your customer" regulation — a bit like a digital passport."
I went through the long report and extracted the following accounting automation insights:
- Blockchains can reduce spreadsheet funk. Sharing spreadsheets has become the norm in the financial world for being a flexible way to send quantitative information along with context and some formulas here and there; it's how we auditors often get data from the client when asking for a breakdown of an account we are looking into as a part of the audit. It's also error prone. Blockchain, in a sense, is a "napster-esque" way of sharing financial information that ensures a common data structure between the sender and the receiver thereby eliminating the manual verification/handling of spreadsheets (see pages 3 and 10).
- Blockchain can enhance "assurance", where it's not feasible for auditors to do so. On page 16 the report discusses the role of smart identities in assisting the sharing economy. It talks about how required digitally signed user reviews will have greater data integrity as it could reduce the risk of self-inflated reviews. Although people rely on such reviews to buy books, rent hotels, etc., there is risk of fraud where the seller will inflate reviews or pay people to do so. However, with a blockchain enabled smart identity there's a higher level of assurance that the end-user can place on the reviews as it harder for the site owner to fake the reviews due to fact the review is digitally signed. Of course no audit firm would have audited such reviews. But I think that's the point: the blockchain technology fills an an assurance need that auditors couldn't, simply because the delivery of such a service wouldn't be profitable.
- Blockchain automation will reduce the need for back-end clerical staff (aka accountants): When looking at the application of blockchain to the title insurance industry (see pages 33-39), it notes how 75% of the industry premiums relate to headcount costs. GS puts the reduction in clerical staff by 30% and a 20% reduction in variable expenses (e.g. commissions, marketing, etc.). Blockchain - without AI enhancements - will automate accounting work as part of the automating knowledge work trend. This is of course more clerical tasks, but blockchain will likely result in less headcount within the finance department.
- Role for third party assurance reports in a permissioned blockchain: The consensus mechanism in the permissioned blockchain is quite different than it's public counterpart, which relies on the proof of work (POW). (See the Khan Academy video, below for the POW and the blockchain section in this post) This is not the case for permissioned system which require the consortium who set-up the blockchain to determine how they will work with each other. This could require auditors to provide assurance over the implementation of blockchain similar to what the SOC report does for cloud computing companies. The report discusses how (see page 29) on how the blockchain will enable "Smart Grid Blockchains" to essentially acts as the record keeping and payment system of energy exchanged by the household owner who has windmills, solar panels to the power grid. But how do we ensure that this being calculated properly? Well, that's where the Processing Integrity Principle of the SOC3 assurance report comes in. It could provide assurance that the blockchain-accounting-payment system is processing the data in complete, accurate and timely manner.
- Greater visibility, means greater opportunity for audit analytics. One area of cost savings associated with a blockchain enabled title insurance industry is that actuaries will be better able to assess risk because of "greater historical transparency and immutability into the property registration system" (see page 38). Consequently, where a material amount of transactions are on a blockchain auditors will have (1) easier access to the data (not a trivial matter by any means!) and (2) can run better analytics to identify irregular transactions and (3) enable better ways to assess estimates.
- Value versus hourly billing: In a number of the use cases identified (e.g. title insurance, settling equities, KYC; see pages 38, 51, 75) noted how the gains (read: headcount reduction) from blockchain enabled automation are expected to be passed on to the customer. Why is this relevant to audit? Audit firms could be expected to hand over automation windfalls to the client and further reduce fees. On the one hand, the more automated the audit, the potentially less fees that audit will capture. On the other hand, regulators may want the auditors to do more with the budget that has been freed up. So the revenue, profitability of highly automated audits will depend on how the regulators re-draw scope in light of such advances.
Despite having the reputation as a great-vampire-squid, the GS report is quite useful for those working in the blockchain space in identifying the potential for this exponential technology.
