Chinese digital bank WeBank has launched a new blockchain infrastructure named POTOS (Proof of Trust and Origin of Services) to accelerate the tokenisation of real-world assets (RWAs). Developed on an enhanced version of FISCO BCOS, an open-source blockchain framework, POTOS aims to tackle key issues in digital asset transformation, particularly focusing on traceability, trust, and compliance.
WeBank’s move signals a growing interest among financial institutions in leveraging blockchain for RWAs. While tokenisation of RWAs such as property, carbon credits, and financial instruments has gained traction globally, its large-scale adoption is often slowed by regulatory, technical, and trust-related challenges. POTOS is designed to address these pain points by offering a compliance-ready and privacy-preserving blockchain environment.
A key differentiator of POTOS is its multi-chain architecture, which allows various industries and application types to build dedicated business chains. These chains are unified under a central “meta service system” that connects different networks while enabling on-chain and off-chain data exchange. This structure aims to balance decentralisation with regulatory compliance and ecosystem coordination.
To support this ecosystem, POTOS introduces a meta asset protocol. This protocol enables asset issuers to define their own rules, such as access control, pricing logic, KYC requirements, and cross-chain compatibility. This modular design supports the diversity of real-world asset types while maintaining transparency and verifiability across platforms.
Additionally, POTOS supports ZKP-based (Zero Knowledge Proof) privacy technology, a growing demand in digital finance. By enabling privacy-preserving operations, the infrastructure ensures that sensitive business logic can be validated without exposing actual data, crucial for regulated environments like finance, healthcare, and supply chains.
WeBank is already working with ecosystem partners on early implementations of POTOS, particularly in areas such as supply chain finance and green finance. These sectors often deal with fragmented data and compliance-heavy processes, making them ideal candidates for blockchain-powered transformation.
The launch of POTOS aligns with China’s cautious but progressive stance on blockchain technology. Although cryptocurrency trading remains heavily restricted, blockchain innovation especially in enterprise and regulated sectors is being actively encouraged.
With POTOS, WeBank aims to create a foundational layer for trusted digital asset ecosystems. Its success could pave the way for wider adoption of RWA tokenisation in Asia and beyond, bringing traditional assets into the blockchain era with greater transparency, efficiency, and trust.
