When talking about blockchains, we commonly think of its applications in the future. “Blockchain will solve this, blockchain will achieve that”. It’s easy to forget that blockchains are already deployed in the wild.

Pick an industry, from automobiles to artificial intelligence, and odds are you’ll find examples of blockchains in action. In all quarters and all circles, blockchains are making their mark. Even the US Treasury is in on the act, advocating for more pilot projects and test programs.

The ‘World Economic Forum’ anticipates that 10% of global GDP will be stored on the blockchain by 2025. That means the global executives out there are preparing for this seismic shift, and are ready to completely back its implementation. The impact of distributed ledger technology could be as grand as the internet revolution itself.

The use cases differ, but the benefits derived from using the technology remain unchanged: transparency, immutability, redundancy and security. In 2018, new blockchain initiatives are launched every day. Here are 50 examples of blockchains in use around the globe.

Government

A number of governments have expressed an interest in blockchain technology to store public records on a decentralized data management framework. Blockchain will enable urban and rural citizens throughout Finland to access records.Other use cases include government applications such as education, public records and voting.

Waste Management

Waltonchain’s RFID technology is being used by a Smart Waste Management System in China. Using Walton’s blockchain, the project will enable supervision of waste levels to improve operational efficiencies and optimize resources.

Identification

Zug in Switzerland, known as “Crypto Valley” has developed a blockchain project in partnership with Uport to register residents’ IDs, enabling them to participate in online voting and prove their residency.

Border Control

At present, passengers on the Eurostar train between the two countries undergo border control checks at multiple points. Blockchain would provide a means of ensuring that the data has not been tampered with and is verifiably accurate.

Healthcare

Medical records are notoriously scattered and erroneous, with inconsistent data handling processes meaning hospitals and clinics are often forced to work with incorrect or incomplete patient records. Healthcare projects such as MedRec are using the blockchain as a means of facilitating data sharing while providing authentication and maintaining confidentiality.

Enterprise

Clients of Microsoft Azure Enterprise can access the Ethereum Blockchain as a Service. This provides businesses with access to smart contracts and blockchain applications in a secure hosted environment.

Google is also reported to be working on a proprietary blockchain to support its cloud-based business. Parent company Alphabet is developing a distributed ledger that third parties will be able to use to store data, believed to be in regards to Google’s cloud services for enterprises, with a white label version for companies also in the works.

Medical

Medical centers that have digitized their patient records don’t distribute their data across multiple facilities, instead keeping them on-site on centralized servers. These are a prime target for hackers, as evidenced by the ransomware attacks that struck NHS hospitals in the UK. Even if security risks are overlooked, there is still the problem of fragmentation. There are currently more than 50 different electronic healthcare record (eHR) software systems that operate in different hospitals, often with dozens of different packages within the same city. These centralized systems do not interoperate with one other and patient data ends up scattered between disparate centers.

In life-and-death settings, the lack of reliable data and sluggish interfaces may prove devastating. Patient privacy is maintained on a secure decentralized network where access is granted to only those who are medically authorized and only for the duration needed.

Music

One of the main benefits of blockchain technology is the way it removes intermediaries or middlemen. The music business is a prime example of an industry whose inefficiencies have seen artists poorly remunerated for their efforts. A number of blockchain-based projects have sprung up seeking a fairer deal for music creators, including Artbit, overseen by former Guns N Roses drummer Matt Sorum.

Carbon Offsets

As a heavily industrialised nation, China’s environmental footprint is substantial. In March 2017, IBM launched the Hyperledger Fabric blockchain in conjunction with Energy-Blockchain Labs, as a means of tracking carbon assets in China. This creates a measurable and auditable system for tracking emissions, and facilitates a tradable market for companies seeking to offset their energy consumption whilst incentivizing greener industrial practises.

Supply Chains

Supply chain management is seen as one of the most beneficial use cases for blockchain, as it’s ideal for industries where goods are passed through various pairs of hands, from beginning to end, or manufacturer to the store . IBM and Walmart have teamed up to launch Blockchain Food Safety Alliance in China. The project, run in conjunction with Fortune 500 company JD.com, is designed to improve food tracking and safety, making it easier to verify that food is safe to consume.

China is proving to be a ripe test bed for blockchain projects, for it’s also home to the world’s first agricultural commodity blockchain. Louis Dreyfus Co, a major food trader, has set up a project with Dutch and French banks which are used for selling soybeans to China, with transactions settled quicker than traditional methods thanks to the use of blockchain technology.

Diamonds

The De Beers Group, the world’s most famous diamond company, now has its own blockchain up and running, designed to establish a “digital record for every diamond registered on the platform”. Given concerns about the source of diamonds, and the ethics concerning their country of origin, coupled with the risk of stones swapped for less value ones along the line, blockchain is a natural fit. Because each record is indelible, it will ensure that data for each stone lasts as long as the diamonds themselves.

Real Estate

Ukraine holds the honor of becoming the first nation to use blockchain to facilitate a property deal. A property in Kiev was sold by prominent cryptocurrency advocate and TechCrunch founder Michael Arrington. The deal was enabled with the aid of smart contracts on the Ethereum blockchain, and is intended to be the first of many completed by Propy, a startup specializing in blockchain-based real estate deals.

Fishing Industry

Blockchain is now being used to support sustainable fishing. Illegally caught fish is an endemic problem within the industry, and distributed ledger technology provides a means of proving where fish were caught, processed and sold. This ‘net-to-plate’ chain allows inspectors to determine whether fish had come from regions notorious for human rights abuses or from countries that are affected by economic sanctions.

Fine Art

Similar to the diamond trade, the art industry is dependant on the provenance and authenticity of artworks. While blockchain cannot authenticate a painting to determine whether it is an original or forgery, it can be used to prove the piece’s previous owners. In addition, blockchain is now used as a means of acquiring art. It’s another example of how blockchain technology can be used to make tangible objects easily tradable and exchangeable from anywhere in the world, without the need to physically transfer them from secure storage.

Public Utilities

In the Australian city of Fremantle, an ambitious project focused on distributed energy and water systems is using blockchain technology. Solar panels are being used in the sun-blessed region to capture electricity, which is then used to heat water and provide power, and the data recorded on the blockchain.

Chile’s National Energy Commission has begun using blockchain technology as a means of certifying data pertaining to the country’s energy usage. Sensitive data will be stored on a blockchain as part of an initiative to help modernize and secure the South American nation’s electrical infrastructure.

LGBT Rights

Blockchain can be helpful in building the “pink economy”, as well as helping the LGBT community to fight for their rights without revealing people’s identities. The latter is an extremely important issue since hate crimes are a recurring problem within the gay community, especially in countries notorious for human rights abuses and where homosexuality is outlawed or at least frowned upon.

Cat Bonds

Cat bonds can be the only hope for people who have been victims of earthquakes, tsunamis and other natural disasters. Blockchain allows for quick and transparent settlements between parties, and creates certainty that the system will remain operational even without human operation. Blockchain has now successfully been used as a cat bond settlement mechanism.

Tourism

Blockchain is being researched as a means of improving Hawaii’s economy by giving tourists an opportunity to pay for local goods and services with bitcoin and other currencies. This way the state’s government hopes to attract tourists, especially from Asia, to spend more money and eventually help Hawaii to develop economically.

National Security

In 2016, the US Department of Homeland Security (DHS) announced a project that would use blockchain as a means of securely storing and transmitting the data it captures. Using the Factom blockchain, data retrieved from security cameras and other sensors are encrypted and stored, using blockchain as a means of mitigating the risk of data breaches. The project is still ongoing.

Shipping

Blockchain’s suitability to recording shiping data is self-evident. A number of projects have distributed ledger technology to work in this domain, using it within the maritime logistics industry to bring transparency to the unavoidable bureaucracy in international trade. Maersk, one of the largest global shippers, was the pioneer to make use of blockchain and now ZIM have picked up the torch.

Taxation

As one of the world’s most technologically advanced countries, it’s no surprise China has become one of the first and most prominent adopters of blockchain and everything it offers. It has decided to use the technology to facilitate taxation and electronic invoice issuance in a project headed by Miaocai Network in conjunction with the State Administration of Taxation.

Mobile Payments

Cryptocurrencies with its underlying blockchain technology is being used to facilitate mobile payments in a wide range of projects. One of the latest initiatives announced, scheduled to launch in the fall of 2018, will involve a consortium of Japanese banks. They’ll be using Ripple’s technology to enable instant mobile payments.

Land Registry

Blockchain once again proves that it’s not just applicable in the crypto space and by small companies. The government of Georgia uses it to register land titles. They have created a custom-designed blockchain system and integrated it into the digital records system of the National Agency of Public Registry (NAPR). Georgia is now taking advantage of the transparency and fraud reduction offered by blockchain technology.

Computation

Amazon Web Services have collaborated with Digital Currency Group (DCG) to improve their database security with the help of blockchain. They will provide a platform for DCG’s startups to work, as well as technical support for their projects.

Insurance

Blockchain in the insurance industry is often talked about, but many don’t know the technology has already been implemented. For instance, Insurer American International Group Inc, in partnership with International Business Machines Corp, has completed a pilot of a so-called “smart contract” multi-national policy for Standard Chartered Bank PLC and plans to manage complex international coverage through blockchain.

Endangered Species Protection

A man is a wolf to another man, and an even bigger wolf to animals. ‘Care for the Uncared’ is an NGO that is working with leading developers to find a way to preserve and protect endangered species using blockchain technologies.

Advertising

New York Interactive Advertising Exchange in partnership with Nasdaq is using blockchain to create a marketplace where brands, publishers and agencies can buy ads. The process is simple, though as secure as it can potentially be, using an open protocol on the Ethereum blockchain.

Journalism

Permanence is now a hot topic in the journalism trade. One wrong move and years of hard work and research could go down the drain. Blockchain is one smart solution to the problem. Civil, a decentralized journalism marketplace, apart from obvious blockchain benefits, offers an economic incentive model for quality news content, coupled with the ability to permanently archive content, which will remain accessible at any time in perpetuity.

Smart Cities

Smart cities are not the stuff of science-fiction anymore. Taipei is attempting to position itself as a city of the future with the help of Distributed Ledger Technology. It has announced a partnership with IOTA and they are already working on creating cards with light, temperature, humidity and pollution detection.

Oil Industry

One of the leading players in the commodity market, S&P Global Platts, is trialling a blockchain solution that’s being used to record oil storage data. Weekly inventories will be stored on the blockchain, reducing the need for manual data management and minimizing the chance of human error.

Railways

In Russia, rail operator Novotrans is using blockchain technology with a goal to improve the speed of its operations. The company, which is one of the largest rolling stock operators in the country, will be using blockchain to record data pertaining to repair requests, inventory and other matters pertaining to their operations. The idea is that blockchain records will be more resistant to tampering and data corruption..

Gaming

One of the most influential companies in the gaming industry, Ubisoft, is researching on how to implement blockchain into its video games. Specifically, it’s focusing on the ownership and transfer of in-game items such as rewards and digital collectibles. These have already been successfully demonstrated in action using the Ethereum blockchain.

Car Leasing

Blockchain’s distributed ledger technology is ideally suited to registering records of any kind in a secure and unalterable manner.

Energy Distribution

One of the biggest challenges facing the energy industry, companies in the habit of trading surplus supply need infallible record keeping. Tracking energy allocations in real time, and ensuring efficient distribution through the supply chain requires multiple data points, and also mandates close cooperation between all entities.

Every day, the number of blockchains used in real world scenarios grows. From logistics to fine art, it’s hard to find a sector that hasn’t been touched by this transformative technology. We have reached a point where the technology has proven itself to be superior than the current modus operandi.

The ‘WEF’ predicts that by 2025 the world will see mainstream blockchain adoption. But after examining the use cases already in the implementation stages we have to ask, we have to ask, will it really take that long?

There’s only one small kink in the chain holding everything back. That kink is known as interoperability.

Think of a river that has peacefully flowed along for the past 15 years, then all of a sudden a storm appears and it rains for weeks on end, turning the river into a raging torrent, sweeping away everything in its path. That river is the Web 2.0 and the storm of blockchains have already changed the internet landscape. So what remains? When the rain stops and the floods subside, with the old foliage swept away, a vast swathe of fertile land awaits to be farmed.

The river, which facilitated the flow and interoperation within the natural ecosystem is gone. And the same goes for the Web 3.0, we can see growth in various sectors but they are still largely incompatible with each other. But ‘hey presto’ there’s already a solution in the works for that.
