Toyota Develops Blockchain Framework to Digitize Vehicle Ownership and Mobility Value

Toyota is advancing its exploration of blockchain technology to digitize vehicle ownership and unlock the value of mobility assets. The automaker's Blockchain Lab, part of its R&D division, is developing a framework that leverages a blockchain-based "Trust Chain" to manage complex relationships in vehicle registration, insurance, and maintenance. By doing so, Toyota aims to address structural gaps—organizational, industrial, and national—that have historically constrained mobility as an asset class [1].

The company introduced the concept of the Mobility-Oriented Account (MOA) last year, which conceptualizes mobility as an abstract account tied to user interactions. However, it became evident that the notion could not fully encapsulate the multifaceted relationships within mobility. As a result, Toyota shifted its focus to a network-based perspective, emphasizing the interconnected nature of mobility and the value it generates [1].

The latest initiative centers on the Mobility Orchestration Network (MON), a protocol-layer blockchain architecture designed to bridge organizational, industrial, and national boundaries. MON integrates three on-chain verified proofs—Institutional, Technical, and Economic—to establish a comprehensive identity for mobility assets. Institutional proof verifies vehicle title, insurance compliance, and legality. Technical proof includes VIN, manufacturing data, and sensor integrity. Economic proof assesses usage, maintenance, and revenue history [1].

This framework aims to streamline trust orchestration across sectors, reinforcing the value of mobility by connecting disparate systems seamlessly. The ultimate goal is to enable global circulation of mobility value without disrupting existing local ecosystems. MON is being designed as a protocol, not a single platform, allowing for flexible integration across different systems [1].

In terms of implementation, MON splits the MOA into two distinct accounts: T-MOA and U-MOA. T-MOA holds finalized institutional and economic proofs, while U-MOA manages real-time operational verifications, such as driver credentials and vehicle status. A tokenization framework is also being developed to enable the transition from non-fungible mobility ownership via NFTs to fungible financial assets, reflecting the evolving nature of ownership and liquidity [1].

Toyota’s blockchain architecture employs a multi-chain strategy, with Avalanche as the foundational layer. Separate chains are deployed for Trust, Capital (tokenized assets), Utility (mobility operations), and Stablecoin networks. These chains are interconnected via Avalanche’s Interchain Messaging (ICM) system, ensuring secure and complete communication across different blockchain networks. Notable protocols like IBC from Cosmos and CCIP from Chainlink are integrated into this intricate network [1].

An off-chain to on-chain bridge, known as the Trust Gateway, facilitates the transition to trust-based systems. This mechanism incorporates Verifiable Credentials, Decentralized Oracles, and Trusted Intermediaries to enhance credibility and interoperability [1].

Toyota’s exploration of blockchain reflects a broader shift in how mobility is perceived—not merely as a mode of transport, but as a valuable asset. As electric and autonomous vehicles gain traction, the potential to decouple mobility from traditional constraints is becoming increasingly relevant. Toyota’s research underscores the challenges that remain in achieving this vision and the strategic use of blockchain to overcome them [1].
