The world as we know it has changed significantly in the last decade. As Executive Chairman of the World Economic Forum, Klaus Schwab, said way back in 2015, we are currently living through what could be considered as the Fourth Industrial Revolution. 

Robotics, AI, quantum computing, fully autonomous vehicles and more are changing the way we work, the way we communicate and, importantly, the way we store and share information. 

The manufacturing sector is no exception, and it is currently seeing a resurgence of interest in next generation technologies, with blockchain in particular capturing the imagination of many. Its application in cryptocurrencies, the broader ramifications of being able to store information in a decentralised manner, and its facilitation of smart contracts could pave the way for a complete overhaul in the way we make new products. But what exactly is blockchain technology, can it be beneficial to your business and if so, how? 

Going back to basics

Put simply, blockchain is a technology that represents an advancement in the way that information is recorded and held. Fundamentally blockchain is a database, or ledger, of information, however its technical composition means that users can have absolute confidence that the data being displayed is complete, accurate and, by all intents and purposes, infallible: once information is written onto a blockchain, it is (close to) impossible to change that information. Blockchain also works on a distributed basis, which means that the ledger of information is not held in one, single location but concurrently on multiple computers across a network. To use a very rudimentary analogy, picture a write-only Excel spreadsheet (where new cells can be added but existing cells not amended), of which a copy is held by every party that could want to view it.

The benefits of a blockchain from an information storage perspective are threefold. Firstly, the information can be considered as up to date and accurate because, when information on a blockchain ledger is updated, everyone who holds a copy of that information on the blockchain network is notified of the update. Secondly, the information can be considered secure, as it is not held in a single place, so there is no centralised point of failure, and equally, no single party can force an update on their version of the information, because all other parties are holding a different version. The final benefit is efficiency. As all participants with access to a blockchain network hold a copy of the information, there is no need to go to an intermediary or third party to ask for it, which can take time, extra costs, and another layer of unnecessary process. Everyone has equal access to all the information held.

So how do these benefits correlate to a real-life scenario? Imagine if you are going to your local supermarket and want to buy salad that is organic. How confident are you that the packaging is factual and not a marketing ploy? In this scenario, you would have to take the packaging at face-value, but if you applied blockchain technology to it, by simply scanning a QR code a customer could have access to every facet of information, ranging from where the salad was grown, how it was transported, stored, packaged, and ultimately placed on the shelf of the store you are attending. This has much broader industry-wide ramifications because, after all, how do manufacturers cross reference the information that is presented to them? What measures do you take to confirm that the information is correct, and what cost or time is incurred in doing that?

Sector-specific applications

For manufacturers, blockchain technology could help build transparency throughout the entire supply chain, ranging from quality assurance of the source material used in a product, tracking or tracing the product to your distribution network, and ensuring that the product is not counterfeited during its journey. From an auditing and accountability perspective, the utilisation of this technology can be revolutionary. For example, a manufacturer releases a product that includes parts from multiple suppliers and finds out that the product contained one faulty part, resulting in a product recall. By using the blockchain to track who the supplier was, they can contain the issue quickly and easily whilst reducing the time and costs required to do so. 

Additionally, blockchain technology can facilitate the use of smart contracts, which are pre-programmed transaction protocols that are automatically executed once the terms of a contract are met. For manufactures, this can mean significantly reduced turn-around times, lower transaction costs and far less paperwork for both buyers and sellers. 

While blockchain roll-out blockchain across the sector is still in its infancy, there are early adopters – particularly in the automotive industry – that are leveraging the technology. For example, German car manufacturer BMW launched ‘PartChain’ in 2020, a blockchain platform that allows the company to track a component’s journey from its origin to the factory. By adding its suppliers to the platform, BMW will have what is essentially a complete view of its supply chain, allowing for significantly improved compliance and a clearer audit trail. For manufactures that rely on an international supply chain, the opportunities of rolling out this technology, and the benefits of doing so, are limitless. 

Although many applications of the technology are still in development, or even merely theoretical, its potential to impact supply chain and the broader manufacturing sector cannot be understated. It is our view that those companies that can identify opportunities for using blockchain in their business – and implement it successfully – will almost certainly gain an advantage on their competitors. Therefore, the time is now for the c-suite to arm themselves with an understanding of how blockchain works and, arguably more importantly, the benefits it can offer so when that the right opportunity for their business to embrace blockchain presents, it can be grabbed with both hands. Ignore blockchain at your peril; if wider adoption begins to take place it could be a gamechanger for the manufacturing sector.
