Blockchain: What It Is and How It Can Help Manufacturers

Building better, smarter, and more secure supply chains

Published: Tuesday, May 14, 2019 - 12:02

How do you know if your election vote is really counted? How do you know the person you’re chatting with online really is who they say they are? And how do you know if a product you purchase has really met quality standards?

These three scenarios may not seem like they have much in common, but there is a common thread: blockchain, a decentralized, open-source ledger that could hypothetically be applied to each to give you the certainty you want in each situation.

The business value-add of blockchain is projected to grow to more than $175 billion by 2025, and exceed $3 trillion by 2030, according to Gartner, a leading global research firm. But do you really know what blockchain is? Before delving into its benefits for manufacturers, here’s an explanation of blockchain.

Blockchain explained

Mention blockchain, and some people immediately tune out. So I’ll try to make this as painless as possible. Even if you determine that blockchain has no place in your small or medium-sized manufacturing business, it’s still good to have a basic understanding of the concept because it’s sure to come up sometime in conversation with others in your industry.

Beginnings in Bitcoin

To start, you may know that blockchain is rooted in digital currency such as Bitcoin. With digital currency, there is no bank or middleman involved, which requires the need for checks and balances.

To keep track of transactions, a digital ledger was created that people all over the world can access in order to validate transactions on their personal computer. Sounds a bit like a Google Doc, right? Unlike a Google Doc, however, people can only add to the ledger, not make changes; also, instead of having one ledger accessible to everyone, the ledger is duplicated across hundreds, thousands, or even millions of locations. An addition to one person’s ledger is updated to everyone else’s ledger, and it cannot be undone.

Because the ledger is public and verifiable with no central location, it’s virtually hack-proof, and because there is such a vast number of record keepers, it’s impossible for anyone involved in a transaction to lie about the currency’s whereabouts.

So why is it called blockchain? A record of a transaction is a “block,” and it becomes part of a “chain” of transactions. Think of it this way:

Bob sends digital currency to Jane.

The transaction is shown online as a block.

The block gets distributed across the network.

The network verifies the transaction.

The block is added to the chain, reconciled across the network, which creates a permanent record.

Bob’s record of ownership moves to Jane.

Cryptocurrency advocates like the distributed storage without the need for a middleman because without a bank or online payment system such as PayPal verifying transfers, transfers are faster, and no one is taking a cut of the money.

The evolution of blockchain

The blockchain concept was so beneficial to the development of Bitcoin and other cryptocurrencies that it was only a matter of time before it began to be applied to other industries. Now, blockchain is being used as a digital ledger for nonfinancial transactions.

Today, blockchain is being taken so seriously that IBM has 1,000 employees working on blockchain-powered projects. The IT giant has also put aside $200 million for research and development. In addition, other firms increased blockchain investing to more than $2 billion in 2018.

But blockchain’s greatest potential to deliver business value is in manufacturing.

Combined, blockchain and the internet of things (IoT) are poised to revolutionize the manufacturing industry, reducing recalls while increasing product safety, track and traceability, warranty management, and maintenance, repair, and overhaul (MRO). It’s also expected to lead to new usage-based business models for smart, connected products.

Here’s how it will work.

Blockchain in manufacturing

Transparency within a supply chain is critical to the manufacturing business, and blockchain can deliver that in spades. With blockchain, visibility is increased across every area of manufacturing—from suppliers, strategic sourcing, and procurement, to shop floor operations including machine-level monitoring and service.

An effective and efficient supply chain is a critical component of manufacturing. However, with supply chains operating across multiple organizations, states, and even countries, it can become difficult to gain transparency into each moving part. Making matters worse, there is often no uniform method of recording, storing, and exchanging data.

This is where blockchain comes into play. Blockchain has the power to build better, smarter, and more secure supply chains, tracking a product’s journey every step of the way. No longer do individuals within a supply chain have to wonder when materials shipped out, who handled them, and when they’ll arrive; the trail is audited with real-time visibility and recorded as blocks in a chain.

“Many manufacturers are very excited about blockchain’s potential ability to verify goods moving through the manufacturing supply chain,” says Greg Cline, head of research for the Aberdeen Group’s Manufacturing, Product Innovation, and Engineering practices division. “The highly transactional and often multistep nature of business process services means that the potential applications of blockchain in manufacturing are significant.”

What manufacturers are saying

A recent study by the Capgemini Research Institute provides valuable insights into how blockchain can improve supply chains and manufacturing. The institute surveyed more than 730 organizations around the globe regarding their current and planned blockchain initiatives. Key takeaways of the study include the following.

The top three reasons manufacturers are investing in blockchain investments are greater cost savings (89%), enhanced traceability (81%), and enhanced transparency (79%). Manufacturers also cited higher revenues (57%), reduced risks (50%), the creation of new business opportunities (44%), and the ability to be more customer-centric (38%). Manufacturers in highly regulated industries such as aerospace and defense, medical devices, consumer packaged goods (CPG), and pharma were most excited by the improved track-and-traceability measures.

Many manufacturers believe product recalls, which typically cost on average $8 million, could be avoided with improved track and traceability. Blockchain’s general ledger structure provides a real-time audit trail for all transactions within a supply chain. Because transactions are secured against modifications, blockchain is ideal for industries with strict compliance regulations.

Digital marketplaces, tracking critical supply chain parameters, tracking components quality, preventing counterfeit products, and tracking asset maintenance are the five areas predicted to experience the greatest blockchain adoption.

Combined with IoT, blockchain becomes even more powerful. Sensors can record changes in temperature and product condition into the blockchain. And blockchain technology can connect an enterprise resource planning system to parts suppliers, instructing IoT-connected devices to order replacement parts just in time for installation, reducing excess inventory or late arrivals.

Blockchain has the potential to support intellectual property in manufacturing through record management. It could be used as a “digital vault,” providing a registry of intellectual property with all checks and balances in place so that ideas could not be stolen.

The future of blockchain

The Capgemini study found that nearly 15 percent of manufacturers are either implementing blockchain across the board or have pilots in at least one site; of this group, more than 60 percent say that the technology has already transformed the way they collaborate with others in the supply chain and plan to increase their blockchain investment by 30 percent during the next three years.

Whether it’s right for your business or not, blockchain is certainly a technology to keep an eye on.

Blockchain Beginning

I have been hearing "Blockchain" in the context of cryptocurrency and govenment operations for some years, and I get the concept. What eludes me is the genesis of the chain. Any chain begins with one link and, maybe I am missing something, it would seem logical that the blockchain must begin as one block.  And, until that block replicated to multiple locations, be vulnerable. In my mind, as the chain grows it becomes stronger, more like chain-mail armor than a chain. But, chain-mail or chain, that first block seems to be a perpetual potential vulnerability.
