Consent and data sharing at scale
Consent is the foundation of any ecosystem: nothing should be shared or done with a person’s data without their clear, informed agreement. This same consent-first approach underpins the whole journey from Open Finance and Open Data. Getting that right for one app is straightforward. Getting it right when many parties share data across a network is the hard part — and it’s where trust is won or lost.
How consent works when many parties are involved
In an ecosystem, a consumer typically consents to a third party accessing specific data, or initiating a specific payment, on their behalf — for a defined purpose and period. As data moves along a chain of participants, each step must respect the scope of what was originally agreed. Consent is not a one-time checkbox; it is a live permission that can be reviewed and revoked.
Keeping the consumer in control
Control means three things in practice: the consumer must understand what they’re agreeing to (in plain terms, not buried fine print), they must be able to see and withdraw consent easily, and they should be told honestly if declining will reduce the service. Good ecosystems make consent explicit and legible — the opposite of the quiet, ambient tracking consumers have grown wary of elsewhere online.
The hard technical problems
Doing this at scale raises real challenges: enforcing the *scope* of consent as data passes between participants; keeping a clean, auditable record of who consented to what and when; propagating a revocation quickly across the chain; and applying data minimisation so only the data needed for the agreed purpose is shared. Each participant in the chain shares responsibility for honouring the original consent.
How trust is maintained across the chain
Consent only holds if every party is trustworthy — which brings it back to the trust framework: certified participants, verifiable identity, and a directory that says who’s allowed to handle the data. Consent and the trust framework are two halves of the same guarantee. See: Product Delivery Ecosystems.
