Expand per Theo audio: plain-language user angle (you are not the product), 3 data guarantees (private by default / per-transaction / choose Rings of Trust), participative policy spectrum + hosting/ads choice, anonymized statistics, then strategic tech choices (Solid Pods, Holochain, DWeb with/without blockchain, link to Blockchains & Decentralized-Data) |
Merge Decentralized-Data into Structured Data (per Theo): add data minimisation/local-first, selective disclosure, decentralised identity (DIDs) |

The guarantees above are not just policy — they rest on deliberate technical choices.

==== Data minimisation & local-first architecture ==== | |||
WikiDeal is designed from the outset to '''minimise the platform's access to user data'''. Where mainstream platforms treat user data as a primary asset — collecting, analysing, and monetising it — WikiDeal treats data as '''belonging to users''', held only in trust, for minimum periods, in minimum quantities. | |||
The architecture is '''local-first''': wherever possible, data is stored on users' own devices, and only the minimum necessary information is transmitted to shared Infrastructure. A babysitting agreement, once signed by both parties, lives on the devices of the family and the babysitter. The platform Infrastructure holds a '''cryptographic proof''' that the agreement was signed, but '''not the content''' of the agreement itself unless both parties consent to shared storage. | |||
This architecture is technically challenging — it requires careful design of conflict resolution, backup, and recovery — but it fundamentally changes the data power relationship: '''the platform cannot sell data it does not have'''. Advertisers cannot be served on data the platform cannot access. And when WikiDeal eventually serves millions of babysitters, tutors, and freelancers worldwide, it will '''not''' have created a surveillance corpus of intimate human behaviour. | |||
==== Selective disclosure ==== | |||
For marketplace Transactions, WikiDeal uses a '''selective disclosure''' model: parties share only the data necessary to complete that Transaction; reputation scores are computed locally and verified by the platform without revealing the underlying ratings; and dispute resolution can proceed without exposing private communications to the platform operators unless legally required. | |||
Funders' individual contribution data is likewise kept strictly confidential. Aggregate figures (total number of funders, total CHF raised, distribution of Community vs [[Gov/en/Portal:Economy/Cash-Rewards|Cash Rewards]] allocations) are published transparently; individual allocations are never disclosed without explicit consent. | |||
==== Decentralised identity (DIDs & verifiable credentials) ==== | |||
WikiDeal is evaluating '''decentralised identity''' systems (DIDs, verifiable credentials) to enable trust between strangers without a central identity database. A babysitter's qualifications, background-check results, and reputation history could be '''held by the babysitter themselves''', presented to families on demand, and verified by the platform '''without the platform storing the underlying data'''. This research is ongoing through the WikiDeal [[Gov/en/Portal:R&D/Living-Labs|Living Labs]] programme. | |||
