2. Supply Chain Management

Blockchain technology can document product manufacturing, transportation, and delivery from the supplier to the consumer, offering a tamper-proof historical record.

In supply chain and trade finance, blockchain platforms such as IBM’s Batavia, R3’s Marco Polo, digital trading networks from various banks, and Hong Kong’s trade finance platform streamline document verification to complete transactions in just minutes at a lower cost. This approach addresses the high inefficiency, fraud, and significant expenses associated with manual documentation, transforming the process into a highly efficient and secure system.

A prominent example of blockchain application in supply chain management is Walmart’s collaboration with IBM on the Food Trust Network. With this, Walmart tracks and traces the origin of food products in its supply chain. It enables Walmart to quickly isolate and manage food safety issues, such as contamination.

Through transparent monitoring of goods, blockchain technology can help to prevent substandard products (e.g., counterfeit, low-quality, contaminated) from entering the market.


3. Smart Contracts

Blockchain introduces smart contracts that record the terms of an agreement between two or more parties. These electronic agreements eliminate the need for intermediaries, reduce costs and bureaucratic delays, and prevent third-party interference. Smart contracts can revolutionize various aspects of daily life.

Similar to traditional contracts, smart contracts define an agreement through if-then conditions. These conditions based on deals between two or more parties are inscribed into the contract code, and actions are automatically triggered once conditions are met. Our dedicated blog post on smart contracts explains in detail how they work, what they can be used for, and how they are coded.

For instance, integrating blockchain with the Internet of Things (IoT) makes it possible to monitor compliance with contract terms automatically. In the case of a missed payment in a purchase agreement, the technology could even locate the debtor, showcasing the practical applications of this innovation. Here, you can find more use cases of smart contracts.


4. Digital Identity

Blockchain enables the creation of secure, tamper-proof digital identities, with some experts predicting that these blockchain-based IDs could one day replace traditional online usernames and passwords. Bitnation’s “Blockchain Emergency ID” initiative exemplifies this application by offering emergency digital IDs to immigrants and refugees when their physical documents are lost or confiscated.

The key feature of digital identities built on blockchain is their robust security system, which effectively prevents identity theft in the digital realm. It also showcases the technology’s capability to revolutionize identity verification online.


5. Voting Systems

Blockchain provides a transparent and secure solution for digital voting, tackling electronic voting challenges like compromised voter privacy, voter fraud, the high costs of outdated digital platforms, and transparency issues. Smart contracts and encryption within blockchain significantly increase voting process safety, enhance transparency, and safeguard voter privacy.

Blockchain-based voting utilizes the technology’s security features to allow voters to submit their choices online without revealing their identity. It ensures the integrity of the voting process by making each vote traceable to a unique ID, making tampering and forgery virtually impossible (see image below for illustration of the blockchain based voting process).

In the 2018 midterm elections, West Virginia launched a pilot project that enabled military and overseas voters to submit secure and anonymous votes using blockchain technology via a mobile app developed by Voatz. This initiative represented one of the first instances of blockchain application in a U.S. federal election to improve voting accessibility and security for citizens abroad.

6. Healthcare

Blockchain solves significant healthcare problems, like data fragmentation, interoperability, and security. It secures and decentralizes electronic health records (EHRs), patient consent, and drug tracking. These attributes allow for efficient sharing and verification of medical info among healthcare providers, pharmaceuticals, and patients. Blockchain also boosts health data security, ensures the integrity of clinical trials, and supports new reward systems with micropayments.

For example, blockchain improves drug traceability by securely recording each transaction in the pharmaceutical supply chain (see image below), ensuring the authenticity of medications, preventing counterfeits, and enhancing patient safety. Its transparent and immutable ledger allows for real-time visibility, efficient recalls, and regulatory compliance, building trust in the pharmaceutical supply chain.

MIT developed MedRec, a critical blockchain healthcare application that manages electronic health records securely. MedRec sets up a decentralized, tamper-proof database for medical data, giving secure, quick access to patients, doctors, and providers.
