Decentralized Data Bounty Billboard (D2B2)

AI Quick Summary

Mobility data is currently fragmented and hidden, causing friction where requesters suffer inefficient collection costs while many data holders do not even think of monetizing their data. The Decentralized Data Bounty Billboard (D2B2) solves this by creating a transparent smart contract marketplace that makes market demand visible through authenticated bounties. By retaining raw data off-chain for privacy and using decentralized oracles for validation, the system enables atomic execution of trustless transactions. This ensures that funds and data access are released simultaneously upon successful submission. D2B2 can use differentiated security standards to protect sensitive personal data while lowering barriers for general mobility exchange. Developed in collaboration with BFH & HSLU, the project will deliver a business plan, a functional prototype and security framework to monetize assets efficiently. It establishes the technical and strategic foundation for an application to the next Innosuisse call. The Challenge Companies seeking reliable mobility data face significant market friction: available data remains fragmented and hidden, while data holders (private companies or even individuals) lack awareness of monetization opportunities. This creates missed value for both parties — requesters to spend resources on inefficient and repetitive collection, and holders to forgo income from existing assets.  The Solution We introduce the Decentralized Data Bounty Billboard (D2B2), a smart contract-based marketplace enabling transparent, authenticated data bounties. Data requesters publicly specify their requirements—what data is needed, its intended use, and the reward offered—making market demand visible and attracting potential data holders.  The system employs a modular smart contract architecture where each bounty operates as an individual contract. Raw data assets are retained off-chain to preserve privacy and storage efficiency. By using a decentralized oracle network, the smart contract autonomously validates submission integrity against embedded validation criteria without directly loading the raw data on-chain. Some validation strategies for high value data could include a mechanism that requires human validation by multiple trusted third parties. Upon successful oracle-mediated validation, the system triggers trustless atomic execution: the smart contract simultaneously releases escrowed rewards to the data provider and grants the requester verifiable access to the validated data asset. This dual-transaction mechanism ensures that payment and data transfer are indivisible—if validation fails; neither transaction executes.   By combining off-chain data residency with oracle-mediated validation and atomic execution, our platform eliminates intermediaries while establishing verifiable trust. Data holders can monetize assets with confidence, while requesters gain reliable data faster and at lower cost, transforming the fragmented mobility data market into a programmable, trustless ecosystem.  The combination with blockchain is implemented through the following core mechanisms: Smart Contract-Based Marketplace: The D2B2 is fundamentally a marketplace built on smart contracts. Each data bounty operates as an individual, modular smart contract. Trustless Atomic Execution: The smart contract simultaneously manages the transfer of funds (escrowed rewards) and the granting of verifiable access to the validated data asset. This dual-transaction mechanism is "atomic," meaning both transactions execute only if all conditions are met; otherwise, neither transaction executes, ensuring that payment and data transfer are indivisible. Decentralized Validation: It utilizes a decentralized oracle network to validate the integrity of the data submission against preset validation criteria. This validation happens autonomously and allows the system to confirm data quality without placing the raw data directly on-chain. Off-Chain Data Residency: Raw data assets are stored off-chain to maintain privacy and storage efficiency. The blockchain is primarily used for managing the bounty rules, validation proof, and trustless exchange, rather than data storage. Elimination of Intermediaries: By combining off-chain data residency with oracle-mediated validation and atomic execution, the platform eliminates the need for intermediaries while establishing verifiable trust between data requesters and providers. Barriers to Exploration The primary barrier is guaranteeing data privacy for personal sensitive data, necessitating the deployment of complex privacy-preserving synthetic mobility data generation pipelines while ensuring data utility. This complexity is mitigated by the D2B2 framework's ability to distinguish between sensitive and non-sensitive data, allowing direct exchange of objective measurements without anonymization overhead. The project team, with its successful track record with an Innosuisse-funded project, Posmo Ethical Data Market, has abundant experience in privacy-preserving pipelines, including differential privacy, suppressive k-anonymity, L-diversity, and swapping techniques to generate synthetic mobility data. For non-sensitive data, such as infrastructure sensor data, bike accident reports, road damage, infrastructure utilization or environmental metrics at a train station, the platform allows for direct submission without anonymization. By applying these differentiated security standards, the platform ensures high-value personal data remains protected via proven pipelines while simultaneously lowering the barrier for general mobility data exchange through a programmable, trustless ecosystem. Expected Outcomes The project will deliver three key outcomes: a comprehensive Business Plan developed by the Institute of Applied Data Science & Finance at BFH, a functional Prototype created by the Institute of Data Applications and Security (IDAS) at BFH, and a successfully demonstrated differentiated security standards framework that protects high-value personal data while lowering the barrier for general mobility data exchange. In the business plan, we will explore how to incentivize data donations from various users. As individual and organizational users have heterogeneous intent in using the platform. We will also explore possibilities to promote such a platform on existing corporate platforms such as SBB, SwissPost, TWINT and other payment platforms.

Project Idea Description

The Challenge

Companies seeking reliable mobility data face significant market friction: available data remains fragmented and hidden, while data holders (private companies or even individuals) lack awareness of monetization opportunities. This creates missed value for both parties — requesters to spend resources on inefficient and repetitive collection, and holders to forgo income from existing assets. 

The Solution

We introduce the Decentralized Data Bounty Billboard (D2B2), a smart contract-based marketplace enabling transparent, authenticated data bounties. Data requesters publicly specify their requirements—what data is needed, its intended use, and the reward offered—making market demand visible and attracting potential data holders. 

The system employs a modular smart contract architecture where each bounty operates as an individual contract. Raw data assets are retained off-chain to preserve privacy and storage efficiency. By using a decentralized oracle network, the smart contract autonomously validates submission integrity against embedded validation criteria without directly loading the raw data on-chain. Some validation strategies for high value data could include a mechanism that requires human validation by multiple trusted third parties. Upon successful oracle-mediated validation, the system triggers trustless atomic execution: the smart contract simultaneously releases escrowed rewards to the data provider and grants the requester verifiable access to the validated data asset. This dual-transaction mechanism ensures that payment and data transfer are indivisible—if validation fails; neither transaction executes.  

By combining off-chain data residency with oracle-mediated validation and atomic execution, our platform eliminates intermediaries while establishing verifiable trust. Data holders can monetize assets with confidence, while requesters gain reliable data faster and at lower cost, transforming the fragmented mobility data market into a programmable, trustless ecosystem. 

The combination with blockchain is implemented through the following core mechanisms:

• Smart Contract-Based Marketplace: The D2B2 is fundamentally a marketplace built on smart contracts. Each data bounty operates as an individual, modular smart contract.
• Trustless Atomic Execution: The smart contract simultaneously manages the transfer of funds (escrowed rewards) and the granting of verifiable access to the validated data asset. This dual-transaction mechanism is "atomic," meaning both transactions execute only if all conditions are met; otherwise, neither transaction executes, ensuring that payment and data transfer are indivisible.
• Decentralized Validation: It utilizes a decentralized oracle network to validate the integrity of the data submission against preset validation criteria. This validation happens autonomously and allows the system to confirm data quality without placing the raw data directly on-chain.
• Off-Chain Data Residency: Raw data assets are stored off-chain to maintain privacy and storage efficiency. The blockchain is primarily used for managing the bounty rules, validation proof, and trustless exchange, rather than data storage.
• Elimination of Intermediaries: By combining off-chain data residency with oracle-mediated validation and atomic execution, the platform eliminates the need for intermediaries while establishing verifiable trust between data requesters and providers.

Barriers to Exploration

The primary barrier is guaranteeing data privacy for personal sensitive data, necessitating the deployment of complex privacy-preserving synthetic mobility data generation pipelines while ensuring data utility. This complexity is mitigated by the D2B2 framework's ability to distinguish between sensitive and non-sensitive data, allowing direct exchange of objective measurements without anonymization overhead. The project team, with its successful track record with an Innosuisse-funded project, Posmo Ethical Data Market, has abundant experience in privacy-preserving pipelines, including differential privacy, suppressive k-anonymity, L-diversity, and swapping techniques to generate synthetic mobility data.

The project will deliver three key outcomes: a comprehensive Business Plan developed by the Institute of Applied Data Science & Finance at BFH, a functional Prototype created by the Institute of Data Applications and Security (IDAS) at BFH, and a successfully demonstrated differentiated security standards framework that protects high-value personal data while lowering the barrier for general mobility data exchange.

In the business plan, we will explore how to incentivize data donations from various users. As individual and organizational users have heterogeneous intent in using the platform. We will also explore possibilities to promote such a platform on existing corporate platforms such as SBB, SwissPost, TWINT and other payment platforms.

Furthermore, the successful development and demonstration of this prototype will lay the groundwork for a subsequent application to a further Innosuisse call.
