Understanding Blockchain in Logistics
Blockchain in logistics: Right now, blockchain is changing the rules of the game for logistics and supply chain. By its nature, companies that produce or sell goods must manage large networks of individuals and organizations to supply their operations and run logistics processes. Blockchain – a technology part of industry 4.0 – may transform these daily activities. So, before going more in-depth on how to deploy blockchain in logistics, let’s take a look at this industry.
Logistics is the management of the flow of material things such as inventory or finished goods from one point to another. It involves a very complex operation that requires multiple people and entities to play a part in its handling, production, packaging, transportation, tax management, warehousing, insurance, security, and delivery to customers.
Overall, the complexity of logistics represents a very fertile ground of opportunities for blockchain. Blockchain is a technology with a list of capabilities that could solve many issues along the process. These include traceability and automatization of transactions. But, what exactly is blockchain?
(TL;DR at the end of the article).
What Is Blockchain?
A blockchain consists of an immutable record of data that acts as a decentralized ledger shared by a cluster of computers or “nodes,” which securely registers transactions in “blocks” of data. The nodes that participate in the network will validate the transaction through a consensus mechanism. Once they approve the transaction, the block appends to the blockchain.
To sum up, the immutability features of blockchain guarantee that no person can manipulate the data. This data is stored as an encrypted sequence of transactions that can be tracked nearly in real-time. Blockchain allows a user to track all these transactions, meaning it becomes a valuable feature to trace things across a logistics chain.
Moreover, blockchain offers other useful functionalities to the logistics industry, such as the ability to create and execute smart contracts. Using smart contracts may help, for instance, easily display in near real-time the exact location of a parcel and the identity of who authorized its freight. A smart contract is a code that can be executed automatically and autonomously when the agreed terms are met. For example, Walmart Canada recently launched a blockchain-based platform with freight tracking and payment processing to improve the supply chain to its more than 400 retail stores.
How a Blockchain Works?
To start a transaction (of data), a user must request the validation of the nodes in the network. The nodes will then validate and approve a transaction depending on values such as available funds or permissions to execute a transaction, for instance. Then, the transaction data is stored in a block of data.
Once the nodes approve the transaction, this block of data appends to the blockchain and generates a “hash” code, which is a unique ID. A hash is calculated by an algorithm that transforms information of variable lengths into a code of specific length.
Consequently, the block of data and, therefore, the transaction will remain immutably registered in the blockchain; hence the blocks of data cannot be deleted or altered. This means that to change any record, a user must request a new transaction. The chain cannot be reduced in size; it can only grow by adding new blocks of data to amend past transactions.
Blockchain in Logistics: What Can This Technology Offer?
By deploying blockchain technology, companies may solve many of the challenges and hurdles across supply chains. Managing one of these chains is very complex and involves many stakeholders throughout the flow of goods. Consequently, this might create data silos and insufficient transparency, hence lower levels of trust among organizations.
In short, how can blockchain technology significantly change the logistics industry?
1. Increasing Transparency and Traceability:
As mentioned previously, logistics processes often involve a large number of stakeholders. From factories, customs personnel, and carriers, to banks and insurance companies. Unstandardized procedures and low levels of transparency might undoubtedly result in a lack of trust and hence causing friction among parties.
Alternatively, blockchain technology can help increase transparency by authorizing key users of the stakeholders so they can have visibility throughout the whole process. This means that a blockchain-based application may allow anyone involved and authorized to view where a package is, in near real-time, from leaving the factory and until reaching its destination.
Additionally, the technology offers traceability across the value chain. This visibility can also be aimed at final customers who can reliably view the process of the goods they buy. For example, the mining and gemstones trading company De Beers announced that it would start using blockchain for tracking stones along the value chain. This will likely impact a market where consumers are turning their heads towards ethical purchasing and are becoming more aware of issues such as Blood Diamonds.
2. Leaner and More Optimized Logistics Process:
One of the main problems in logistics is precisely the fact that the process depends on several – if not dozens – different stakeholders. It’s highly probable that all these organizations and entities have their platforms and systems, meaning that technology adoption will most likely be disparate among them.
To improve the flow of goods, the value chain must be unfragmented and optimized. Blockchain technology may solve this by offering a decentralized solution. By using a distributed ledger, all these stakeholders can better trust the system and therefore increase lean communication and processing of packages. In an industry where people still use pen and paper, deploying this technology may certainly go a long way.
For example, logistics corporation Maersk and IBM formed a joint venture to develop TradeLens, a global supply blockchain-based solution to track containers. To date, the platform has processed millions of containers worldwide and captures thousands of documents weekly.
3. Improved Efficiency and Cost Savings
Furthermore, blockchain’s ability to deploy smart contracts can enhance logistics and help cut costs. For instance, smart contracts can automate processes such as customs duties, payment processing, or executing insurance. Consequently, companies may lower costs related to paper filing or interacting with middlemen.
For example, Cloud Logistics is a company that provides blockchain supply chain solutions. This platform offers the possibility to automate the freight auditing process and to leverage data to create future savings.
Overall, there is currently a blue ocean of opportunities for blockchain technology to set sail.

The logistics industry involves a very complex operation that needs to manage multiple people and entities. Blockchain is an immutable and decentralized record of data that offers traceability and automatization of transactions. Specifically, blockchain can leverage logistics and supply chain by:
- Increasing transparency and traceability: Involving a large number of stakeholders with unstandardized procedures and low levels of transparency can lead to a lack of trust and friction among parties. Blockchain allows users to grant authorizations to have complete visibility across the process, facilitating traceability of goods (from the factory to its destination).
- Leaner and more optimized logistics process: When the process relies on multiple stakeholders, technology adoption will most likely be disparate. Blockchain can provide an unfragmented and streamlined platform that replaces pen and paper and increase lean communication and processing of packages.
- Improved efficiency and cost savings: By deploying smart contracts, blockchain can help cut costs automating processes related to paper filing and interacting with middlemen.
