Blockchain-Enabled Leasing: Use Cases, Pain Points, and Technical Solutions

The content originates from JD Tech Day where ZRobot blockchain product manager Ding Wenbin presented a blockchain‑based solution for the leasing industry.

Leasing is described as a low‑cost method for users to obtain the right to use an asset for a defined period, exemplified by phone leasing where credit scores enable rent‑free qualification, followed by order placement, agreement signing, and options to return, renew, or purchase the device.

The main pain point highlighted is breach disputes, such as damaged assets or unauthorized contract changes, which lead to mistrust and costly arbitration; traditional centralized solutions suffer from evidence collection difficulty, long cycles, high costs, and complex procedures.

To overcome these issues, ZRobot proposes an alliance‑chain (JD Zhizhen Chain) that records electronic data immutably, enabling real‑time evidence, tamper‑proof storage, and legal endorsement through judicial nodes, electronic signatures, hash verification, and trusted timestamps.

Key technical steps include generating a SHA‑256 hash (digital fingerprint) of lease agreements and related documents, broadcasting the hash on the blockchain as a transaction with a unique ID, and storing the original files securely on JD Cloud for later verification.

The solution allows parties to retrieve the hash via the transaction ID on a blockchain explorer, compare it with a freshly computed hash, and confirm data integrity, thereby providing reliable evidence for unresolved disputes.

The article also notes Beijing's supportive policies for blockchain, emphasizing non‑tokenized applications, research on underlying technology, and the role of judicial and internet courts in recognizing blockchain‑based evidence.

In summary, the leasing blockchain implementation focuses on information preservation, notarization, and trusted verification, with ZRobot handling the front‑end application and Zhizhen Chain providing the underlying services.

Finally, Ding Wenbin remarks that blockchain adoption is still early and challenging, but emphasizes the importance of tackling difficult problems to create value.
