Spanish Red Cross launches privacy-first blockchain aid platform
The Spanish Pink Cross (Creu Roja) has deployed a brand new blockchain-based help distribution system, RedChain, that guarantees real-time donor transparency with out exposing the identities of the individuals receiving help.
In accordance with a launch shared with Cointelegraph, the platform, developed with Barcelona-based infrastructure supplier BLOOCK and zero-knowledge credential agency Billions Community, goals to digitize “the complete help lifecycle from donation to disbursement.”
It replaces paper vouchers and pay as you go playing cards with ERC‑20 help credit issued on the Ethereum (ETH) blockchain, delivered to a cell pockets that can be utilized at taking part retailers through fast response (QR) codes.
Beneficiary knowledge, together with names, contact data, and case information, is saved fully offchain in Creu Roja’s personal programs. The general public blockchain is used purely as a verification layer, anchoring hashes, timestamps and integrity proofs of transactions quite than private data.

RedChain goals to separate transparency from id
Donors and directors can audit when and the place funds have been allotted and spent, whereas the system is designed in order that no occasion can reconstruct particular person identities from onchain information.
Supply: Creu Roja
A spokesperson from Creu Roja advised Cointelegraph, “Donors can see aggregated, verifiable data on how funds are allotted and spent,” akin to how a lot was distributed inside a program and when disbursements occurred. Nonetheless, “what donors won’t ever see are the identities of beneficiaries or their private circumstances.”
The spokesperson stated that RedChain was “explicitly designed in order that transparency applies to flows and outcomes, to not people, permitting the Pink Cross to be “accountable to donors with out compromising the privateness or dignity of its beneficiaries.”

Humanitarian donors demand verifiable help flows
Creu Roja frames RedChain as a response to mounting strain on humanitarian organizations to show that help reaches its meant objective with out turning susceptible communities into knowledge sources.
“Folks searching for help should not have to decide on between getting assist and defending their privateness,” stated Francisco López Romero, CTO at Creu Roja Catalunya, within the launch.
Recipients will obtain digital credit in a pockets on their telephone and pay at regular checkouts, making transactions indistinguishable from customary purchases and avoiding seen markers that sign somebody as an help recipient.
“We grant them credit score, they usually should purchase, consistent with laws, on the grocery store chain that adheres to our program,” the spokesperson stated. “Nobody could be excluded on account of technical limitations.”

Blockchain as a public notary for help
The system implements a hybrid belief mannequin. ERC‑20 tokens characterize allotted help, whereas spending information and eligibility checks stay in offchain databases linked to onchain proofs.
BLOOCK describes its function as working a “blockchain as a certification layer” structure, the place cryptographic anchors make tampering with inner information detectable with out ever publishing underlying knowledge.
BLOOCK CEO Lluís Llibre advised Cointelegraph, “Becauseevery related state change is cryptographically anchored to a public blockchain, any post-hoc modification of inner information would instantly fail verification towards the immutable onchain proofs.”
He stated that, basically, the blockchain capabilities as a “public notary, confirming that an occasion occurred with out revealing the content material or the events concerned.”
Billions Community, in the meantime, supplies the zero‑data credential layer in order that beneficiaries can show eligibility or authorization with out disclosing their id or attributes. Proofs are held within the person’s personal pockets quite than in a centralized id registry.
