Blockchain is being used for humanitarian innovation as the Spanish Red Cross launches RedChain, a decentralized ledger technology that prioritizes privacy in the modernization of aid distribution while safeguarding recipients data and autonomy.
RedChain: A New Humanitarian Infrastructure
The Spanish Red Cross has launched RedChain, which is based on the technology of blockchain. This technology is designed to improve the efficiency, transparency, and privacy of the humanitarian operation.
Traditionally, the operation of aid distribution has been based on centralized databases, as well as paper-based or even digital data, which are prone to the exposure of personal data. RedChain has been designed to provide a decentralized, privacy-friendly identity solution using advanced cryptographic techniques.
At its core, RedChain utilizes:
- Zero knowledge proofs for user attributes without leaking sensitive information.
- Decentralized identifiers (DIDs) for enabling individuals to control how their data is revealed.
- The use of selective disclosure systems that allow aid organizations access to only the information required for specific aid activities.
For instance, instead of sharing identity information, the user can prove that he or she satisfies the eligibility criteria, such as being a poor household or a displaced person, without divulging the identity, address, and other such sensitive information. This will help minimize the chances of the information being leaked and misused.

Pilot Phase and Implementation
RedChain is in the process of being rolled out as part of various pilot programs, all of which are currently being conducted within Spain, where the Spanish Red Cross is utilizing the technology for resource allocation, identity verification, and aid reporting.
While the initial application of the technology is for local communities, it is expected that the technology can be used for international aid as well, in conjunction with other branches of the Red Cross / Red Crescent Movement.
Key operational goals include:
- Removing administrative frictions in aid programs and eliminating duplication of records.
- Building trust with recipients through empowerment of individuals with their data.
- Enhancement of auditability and accountability of funds and resources.
- Cross-organization interoperability without central data silos.
Why Privacy Matters in Aid Distribution
Humanitarian situations, which may include natural disaster relief, refugee support, and poverty alleviation, frequently require the collection of extremely sensitive personal information. In traditional systems, such information is prone to:
- Breaches and leaks
- Unauthorized Sharing
- Political or economic exploitation
As such, RedChain is, by design, able to mitigate these risks through the use of cryptographic privacy tools.
Zero-knowledge proof, which is part of blockchain technology, enables one to prove that they have certain attributes, such as age and eligibility, without revealing their identity, thus being able to meet strict data protection regulations such as GDPR. This is also in line with international human rights regulations pertaining to the use of personal data.
