Blockchain Technology for Trust, Shipping, & the Supply Chain

Trust makes the world go around. Well at least, it makes the economy go around. Think about it: every single transaction you’re a part of needs trust to be executed. You have to trust the vendor to deliver on your purchase. The vendor needs a guarantee that the buyer will pay. Trust is even being put in the currency used to make the purchase.

But not every transaction goes straight from buyer to seller. Products are sold, bought, and resold several times, and are often transported by several different handlers. Trust is needed for each step of the supply chain.

Currently, trust is established through business history, credit or complex contracts. Consumer lack of trust causes “friction”, and that ends up costing both producers and consumers money. Disputes must be dealt with in court, which is neither time or cost efficient.

Getting something from point “a” to point “b” might seem simple, but in the real world transporting goods is insanely complex. The result is a non-transparent supply chain where many parties are left in the dark.

The core part of the supply chain is producers and consumers being connected by third parties. As we mentioned above, very few companies have the ability to fulfill online orders and any that maintains inventory is going to have to deal with third party producers, re-sellers and transporters.

Lots of possibilities for problems

Currently, once a product leaves your hands, or before it even gets to the recipient, the possession of the goods are entrusted to a shipper. A lot of things can go wrong with transport of goods. Let’s say the producer of Faberge eggs is looking to get their product to an independent fine goods store. The transportation process often involves several shippers, creating a major issue: accountability. These priceless works of art are extremely fragile. Let’s say a box shifts the wrong way and an egg breaks. That issue likely won’t be discovered until delivery is received and the shipment is checked.

With the cost of these beautiful eggs being exorbitant, you’re going to have an angry buyer and they are going to want their money back. But whose fault is this? Who had possession of the good when it broke or was exposed to other undesirable conditions such as extreme temperatures? In this case, the current supply chain supplies no answers. Their solution is for producers and consumers to pay for expensive insurance policies, since usually, no fault can be assigned.

All of these problems cost money, and most of that cost will ultimately get passed on to the consumer. It’s a closed system that operates on a lot of faith, and that doesn’t always work out. The blockchain can offer transparency that could reduce recalls, shipping times and cost.

How can blockchains help maintain trust & accountability

The term blockchain is thrown around loosely, but there’s an important distinction to make. Blockchains like Bitcoin and Ethereum are what are known as open blockchains. Anyone can use them while maintaining a certain level of anonymity, but the information that is transmitted is private.

However, there is another type of blockchain known as a permissioned blockchain. While it partially maintains the same structure, the parties are known but the information transacted is restricted to permissioned parties. This type of blockchain is perfect for business. Business entities aren’t going to throw around their proprietary information to be seen by the public and competitors. They want to operate on a need to know basis. A permissioned blockchain allows businesses to do exactly that.

A partnered technological effort

But how can a blockchain address a “damaged goods” scenario that we described above? The answer is that blockchain alone can’t do this. It can, however, be paired with something called the Internet of Things and act as a permanent immutable ledger.

The Internet of Things describes the interconnectivity of everyday objects via the internet. Ever hear about someone using their phone to control their thermostat? That’s the Internet of Things in action. While the term describes everyday objects, the IoT can also describe a network of sensors. And these sensors could be used to transmit data to the blockchain.

Let’s use food as an example. Produce has to be kept at a certain temperature, or the shipment can spoil or even become unsafe. There are thousands of recalls of unsafe products each year and several outbreaks of foodborne disease, with some even resulting in death. By using the IoT paired with a blockchain, temperature data could be constantly monitored. If temperature could be monitored by sensors, so could other conditions, like humidity, stopping time, and any bumps or jostling of cargo.

If any of these sensors detect a condition outside of the predetermined range, that data would be permanently recorded on the blockchain, alerting the appropriate parties that the shipment has fallen out of agreed upon range. At that point the receiver can refuse the shipment.

If the shipment meets conditions, it is then accepted with the assurance that the shipping conditions were okay. This transparency given to proper parties can give producers and consumers alike more confidence in their purchases and consumption.

It’s already happening

We are already seeing blockchains putting these plans in action. Projects like IOTA and Waltonchain are using different methods to track products along the shipping process. While these cases are still in their test stage, early results seem promising.

While the blockchain may not revolutionize the supply chain overnight, it wouldn’t be surprising to see a gradual shift towards the technology over time.
