How ADB Is Testing Blockchain to Fix Trade, Climate and Public Systems in Asia

ADB’s report shows that blockchain can improve efficiency, transparency, and trust in areas like trade, climate, land management, and education, but only when applied in the right contexts. It is not a one-size-fits-all solution, and its success depends on strong collaboration, clear regulations, and practical implementation.

For years, blockchain was seen as a buzzword tied to cryptocurrencies and speculation. Now, a new report by the Asian Development Bank shows how the technology is being tested in more practical ways across Asia and the Pacific. Working with research and tech partners such as Zhongchao Blockchain Technology Research Institute, InfraBlocks Technologies, Morpheus Network, IBM India, KPMG Digital Village, and Bina Nusantara University, ADB has been running real-world pilots to see where blockchain actually works and where it does not.

The goal is simple: find out whether blockchain can solve everyday problems like slow trade processes, lack of transparency, and weak trust between institutions. The findings suggest that while blockchain is not a miracle solution, it can make systems more efficient and reliable when used carefully.

What Blockchain Really Does

At its simplest, blockchain is a digital record system shared across many users instead of being controlled by one authority. Once data is added, it cannot easily be changed, which makes it secure and trustworthy. It also allows different parties to work on the same data in real time without needing middlemen.

This is especially useful in situations where many organizations are involved, such as trade, banking, or government services. However, the report makes it clear that blockchain is not always the best choice. In systems that already work well, or where speed is more important than transparency, traditional databases may still be better.

Faster Trade and Finance Systems

One of the strongest use cases for blockchain is trade and finance. These sectors still rely heavily on paperwork and manual checks, which slow down transactions. ADB tested blockchain in cross-border financial systems under a project called Tridecagon. The experiment showed that transactions that normally take days could be completed much faster and with less risk.

In another pilot between Thailand and Vietnam, a trade finance deal was processed in under five hours instead of more than a day. This was possible because documents were digitized and verified automatically.

Not all experiments succeeded. A similar project in the Maldives faced technical and cost challenges and had to be paused. But in Mongolia, blockchain helped digitize certificates of origin, allowing goods to be verified quickly and securely. This reduced delays and improved trust between traders and authorities.

Supporting Climate Action and New Ideas

Blockchain is also being tested in climate-related projects. In China, it was used to improve carbon trading systems by creating a shared record of carbon credits. This helped reduce errors and made transactions more transparent.

In Bhutan, blockchain was explored as a way to simplify the process of issuing carbon credits, which is usually slow and expensive. Early results showed that it could lower costs and speed up the process, although scaling the system will require stronger regulations.

ADB also experimented with non-fungible tokens, or NFTs, in Indonesia as a way to raise funds for marine conservation. While the financial results were limited, the project showed that blockchain can open new ways to connect with global audiences and donors.

Improving Land Rights and Education

Beyond finance and climate, blockchain is being used to improve public services. In Fiji, a blockchain-based system was introduced to manage land leasing. Previously, the process could take years due to paperwork and coordination issues. The new system made approvals faster and allowed landowners to give consent digitally.

In Indonesia, blockchain was used in education to store and verify academic credentials. This helps prevent fake diplomas and makes it easier for students to share their qualifications across institutions and even across borders.

A Tool With Promise, Not a Magic Fix

Across all these projects, one lesson stands out. Blockchain works best in systems where trust is low, processes are complex, and many parties need to share information. It struggles when costs are high, systems are hard to upgrade, or regulations are unclear.

ADB's approach has been to test, learn, and adapt rather than push blockchain as a universal solution. The report shows that the technology has real potential, but only when combined with strong partnerships, clear policies, and practical implementation.

In the end, blockchain may not transform everything overnight. But in the right places, it is already helping build systems that are faster, safer, and more transparent.
