Bamboozled by Blockchain? Read on.

 (A 10-minute read)

Blockchain is taking the world by storm. Statista (2021) forecasts a whopping 20-fold increase in global spending from 2017 to 2024.

However, like myself, you may have been wondering ...what exactly is it? Is it just a fad, or something we should all be familiar with already? And should your businesses be implementing it? If so, where and how?

After much reading, and following my learnings from the Warwick Business School’s Digital Leadership module, I have decided to share with you my understanding of; what blockchain technology is, how it works, its pros and cons, and things to consider before you start looking at implementing it across your business. Right at the end, I take a brief look at whether or not Blockchain technology is ready.

1.   So, what is it?

A popular definition developed by blockchain gurus, Don and Alex Tapscott (2016), describes blockchain as:

an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value”

Initially invented by a group of people using the name ‘Satoshi Nakamoto’, blockchain was created to serve as a public transactional ledger of the cryptocurrency, Bitcoin (Nakamoto, 2008). While the actual definition varies across the board slightly, blockchain is essentially what it says on the tin, a chain of blocks that contains information. It is sometimes referred to as ‘Distributed Ledger Technology (DTL)’ which put simply, is a completely open electronic list of connected and verified records that operates across a peer-to-peer network, removing the need for any intermediaries (Statista, 2021). Once data has been stored inside the blockchain, it becomes difficult to change it.

2.  How does it work? The Techy Stuff...

 To understand the technical process behind blockchain, it is important to understand what each block contains (Nakamoto, 2017):

 1. Data – any form of data e.g. for cryptocurrencies, this would be transactional information e.g. details of the sender, receiver and amount of coins.

2. Hash of the block – the unique identity of the block. When a block is created, a corresponding hash is also created. If anything changes within the block, the hash changes.

 3. Hash of the previous block – creates the link of each block to the previous block and is responsible for creating the chain. Note, this does not apply to the first block.

Due to this, any changes to any single block in the link would invalidate the remaining blocks (Simply Explained, 2017).

For added security, making it even harder to tamper with the blocks, some blockchains (e.g. Bitcoin and Ethereum) operate a ‘proof of work’ - a mechanism that slows down the creation process of blocks.

For added security, making it even harder to tamper with the blocks, some blockchains (e.g. Bitcoin and Ethereum) operate a ‘proof of work’ - a mechanism that slows down the creation process of blocks. This means, to be able to tamper with any blocks, the proof-of-concept would need to be recalculated for all the following blocks.

Rather than operating off one central entity, the chain is managed through a peer-to-peer network that anyone can join (Euromoney, 2020). Anyone joining would receive a full version of the blockchain, and each person (i.e. node) can use this to validate and verify that the blocks are not being tampered with. For example, if a new block is created to be added to the chain in the scenario, it is sent to everyone on the network to be verified. Should the hash on this block appear untampered, each node would add this block onto their chain. Alternatively, tampered blocks would be rejected by some nodes.

So, to successfully tamper with the chain of blocks, all blocks on the chain would need amending, each proof-of-work would need re-doing, and the network would need to reach a consensus from most if not all of the nodes on the network (Weking et al., 2019). This makes the possibility of tampering with the chain next to impossible!

Lastly, blockchain uses public-key cryptography to perform tasks like completing transactions (Pal et al, 2021). Public keys are paired with private keys for each user. Anyone can send transactions to the public key; however, the private key must ‘unlock’ it. Blockchain can also store ‘smart contracts’, which can apply automated rules to each transaction and decide how the chain can or cannot be used.

If like me, you're geeking out right now, I'd recommend jumping on youtube and watching some videos after reading this - they're mega useful in getting your head around the concept!

4.  The Good, the Bad and the Ugly

There are several generic advantages and disadvantages to consider. Key ones are as follows:

Pros

Security: The added layers of security as explained above, provide additional security and stability to the system. For example, due to the distributed network, there is less dependability on one centralised system therefore, there is reduced vulnerability to technical failures and cyber-attacks (Songara and Chouhan, 2017). Similarly, as it is almost impossible to amend a confirmed block, this increases transparency and trust within the data (Bahga and Madisetti, 2016).

Reduced Costs: No intermediaries eliminate the risk of trusting one organisation for the storage of information and also reduces costs and transactional fees that are often charged by them. However, note, there are still infrastructure costs involved.

Simplification: Current verification processes through ledgers require multiple ledgers, this can cause clutter and result in unnecessary complications. Blockchain allows for all transactions to be added to a single public ledger, therefore, simplifying the process. This is likely to result in reduced administrative costs for businesses implementing blockchain.

Speed: With the elimination of intermediaries and simplification of the process, transactions can be completed more quickly. For currencies, the move from transactions amongst tangible assets within banks to cryptocurrencies on the blockchain can reduce the time in processing from approximately 3 days to several minutes or seconds (Medium, 2019), also driving down operational costs.

Cons

Amending Data: The process of blockchain making data difficult to amend can be a double-edged sword. In some instances, making changes to data can be required. In this case, it would require making the initial blockchain redundant and creating a new one (Casino et al., 2019). This would require redistribution of details to vendors again and may become more time consuming than intended.

Losing the Private Key: While public keys can be shared, private keys should not be shared as this is what allows a user access to their own data or in the case of cryptocurrency, access to funds (Casino et al, 2019). Therefore, if the key is forgotten or lost by a user, this would result in unrecoverable and permanent loss of data or funds.

Environmental Impact: The proof-of-work step in the process technically means that several network miners are trying to solve multiple solutions each second to validate transactions. Unchangeable data is also being stored on the blockchain indefinitely. Both the process and storage requires substantial energy consumption. Data from Eurostat (2018) showed that in 2015, Denmark consumed 30.7TWh of electricity whereas in the same year, Bitcoin’s annual electricity consumption was 32.56TWh, suggesting that Bitcoin (which operates on blockchain) alone exceeded the energy consumption of entire countries (BBCNews, 2017). It is likely that regulation will come into place requiring companies to declare these figures within annual reports.

Costs: The energy consumption alongside heavy storage constraints results in high costs, the average cost of transaction is thought to be between 75 to 160 dollars (DataFlair, 2021). There are also planning and implementation costs to consider.

 To conclude, blockchain presents an interesting opportunity providing added operational savings and security however, these come with challenges and risks which if properly managed, could result in significant improvements to some businesses.

 However, the technology is still relatively new and unregulated meaning we are still learning about it and we have little information of long-term effects.

However, the technology is still relatively new and unregulated meaning we are still learning about it and we have little information of long-term effects. So, arguably, the facts and figures reported still need to be supported and critiqued further through empirical research. Also, as businesses have begun adopting blockchain, it is possible that we will learn more about its advantages and disadvantages. Similarly, the pace of technology advancements is rapid making the industry disruptive. This is a risk to bear in mind as companies look to implement blockchain.

 It is also worth noting that the pros and cons described are applicable to the concept of the blockchain overall. Depending on the size and demands of the business, there is the option of considering private or public blockchains, and there are key trade-offs with each. Generally, experts believe that a private blockchain may be better suited to larger organisations as they offer higher scalability, high transaction throughput and better access control (DevTeam, 2021).

5. What do you need to think about before implementing Blockchain?

Research shows that only less than 30% of digital transformations succeed (Mckinsey, 2018) so should a company decide to adopt blockchain, there are several factors a company must consider. Some are listed below.

Research shows that less than 30% of digital transformations succeed

People: Blockchain being a new technology requires a unique skillset therefore, offloading blockchain planning and integration to existing development teams is likely to present challenges (DevTeam, 2021). Therefore, companies should seek to conduct a thorough evaluation of who should be involved in planning and implementation.

While blockchain adoption may make financial and time-saving sense to businesses, research suggests that for technology to be successfully implemented, it must be integrated with the users in mind (McKinsey, 2018).

The technology acceptance model (TAM) is useful for understanding the social mechanisms of technology adoption and predicting the adoption decision of users (Davis 1989). There are two main factors in TAM; perceived usefulness and perceived ease of use that result in the user’s attitude and subsequent intention for using the technology. Should the targeted results not be aligned with the perception of the blockchain, this can result in the actual use of blockchain potentially being different than intended. Companies should seek to use this model to predict behaviours and align them.

Public Vs Private: As mentioned earlier, depending on the size and demands of the business, the business will need to decide whether a public or private option is better suited. At this stage, a private solution is likely to demand in-house development of the technology which although is likely to help businesses get ahead of competition, will require upfront sunk costs. On the other hand, there are various public blockchain platforms and enterprise blockchain frameworks already available on the market, each with their own advantages and disadvantages for consideration.

 It is likely that as an understanding of the blockchain grows within the market, ‘off the shelf’ blockchain service solutions will begin to emerge. Therefore, companies could make the decision to ‘wait it out’ until these appear but, this may mean competitors get ahead.

Smart Contract Development: As explained earlier, smart contracts on blockchain allow legally binding agreements to be put into effect between two parties. Should an organisation want to use this feature as a part of the implementation, these will need to be developed carefully as once they are deployed, they cannot be modified.

Hosting and Integration: A company will need to decide where to host their blockchain network, there are various on the market network hosts such as Ethereum and Amazon to consider. Furthermore, moving any process onto blockchain will require integration with other blockchain network participants and both internal and possibly external legacy systems such as with those of suppliers (Gartner, 2021). It is also likely that data across these platforms will need to be standardised. Therefore, companies will need plans to understand how they will interoperate.

Organisational Capability Requirements: Iansiti and Lakhani (2017) suggest that Identifying the degree of novelty (i.e. how new the application is to the world) and complexity (i.e. the effort required for users to understand it), can help executives position its requirements (e.g. processes and infrastructure required) and forecast challenges.

This framework suggests that single-use applications require lower organisational capability development whereas transformational would require the most. Therefore, positioning the type of blockchain adoption within its appropriate quadrant would be beneficial.

6. How can Blockchain be implemented within Supply Chains?

 ...blockchain technology adoption cases to reach over USD 60 billion in 2024, with enhanced capabilities of use in virtually any application e.g. within the creative industry through integration of varied systems, managing commercial transactions and fostering assets

UNCTAD (2020) forecasts blockchain technology adoption cases to reach over USD 60 billion in 2024, with enhanced capabilities of use in virtually any application e.g. within the creative industry through integration of varied systems, managing commercial transactions and fostering assets (Bokhe et al., 2020). One potential application of blockchain is discussed below.

Sustainable Supply Chains

With investors now seeking to invest in environmentally conscientious, socially responsible and ethically governed companies, it is becoming increasingly important for companies to display trust and transparency across their supply chain. The problem with current data is that it can be fabricated and as it moves through supply chains and vendors, correct details can be difficult to find and authenticate (Accenture, 2021). Blockchain can provide indisputable digital authentication (Gartner, 2021). By companies implementing blockchain across their supply chain, they can produce more reliable data and thus meet ESG criteria. However, while this will produce an added layer of trust to the data, as per the Gartner Continuous Truth Assessment Model (2021) it is likely that AI and human verification will still need to take place for complete confirmation.

 

7. However, is Blockchain Ready?

So far, we have seen the benefits and drawbacks of blockchain implementation to businesses. With blockchain solutions expected to rise 20-fold from 2017 – 2024, raises the question of whether the innovative technology, really holds substance or is just a fad?  

Gartner placed blockchain overall, at the bottom of the trough of disillusionment suggesting that Blockchain is still 2 to 5 years from the plateau.

The Gartner Hype Cycle methodology gives us insight into the perceived value of trends and their position on a maturity cycle. It can also help businesses decide risk levels associated with adoption as they change depending on where the technology is within the cycle. In 2020, Gartner placed blockchain overall, at the bottom of the trough of disillusionment suggesting that Blockchain is still 2 to 5 years from the plateau. Given how much we are still learning about it and how each individual blockchain technology is evolving, this is no surprise.

 ...blockchain is headed towards being a less risky investment for companies

Since then, with the onset of the global pandemic in 2020 driving technological advancements, it could be argued that blockchain is beginning to come out of the trough heading to the slope of enlightenment. Most blockchain related technologies however, are positioned on the innovation trigger heading towards the peak of inflated expectations. Therefore, this suggests that while companies and industries that have been early adopters are informing the maturity cycle of blockchain, blockchain is headed towards being a less risky investment for companies however, there is still clearly a lot more learning through empirical research of companies adopting the technology, still to be conducted.

8. Conclusion

Invented in 2008, blockchain has been around for a good 10 years now and clearly has its advantages and transformational potential. However, its full potential going from theory to practice is only just being realised. Early adopters are informing its maturity cycle and thus, second movers are benefiting. However, it is evident that there are still drawbacks and limitations still to be addressed, and blockchain solutions for businesses are still being developed. If you do decide to implement Blockchain, it is strongly advised that you should seek expert advice and ensure a) is the implementation of blockchain actually required and what benefits will this bring and b) ensure it is aligned with the business’ overall corporate strategy and risk appetites as a failed implementation could prove extremely costly.
