Across the UK and Europe, payment sovereignty has moved from policy debate to strategic priority. Policymakers and industry leaders are rethinking their reliance on global networks, seeking greater control over how money moves domestically and regionally.That ambition matters. But sovereignty alone will not make a payment system safer, more private or more trusted. A payment rail can be locally operated and still vulnerable to fraud, impersonation, data misuse and poor user verification. The real opportunity lies in rebuilding payments infrastructure with trust embedded at the core. That begins with identity. The trust challenge in faster payments Real-time payments have changed expectations permanently but speed also changes the risk profile. When transactions are settled in seconds and are difficult to reverse, there is less time to detect error, coercion or fraud before value has already moved.In that environment, trust cannot be assumed. It must be verified. Today, much of the payment experience still relies on fragmented signals. A user may authenticate to login to an app. A merchant may be checked at onboarding. A payment instruction may be screened for risk. But these controls are often separated across different systems, moments and providers. That leaves space for attackers to exploit the gaps between identity, authentication and transaction approval. For sovereign payments infrastructure, this is the opportunity: to design trust into the payment flow from the start. Identity cannot stop at onboarding. It needs to travel with the transaction. A modern payment system should be able to verify that the payer is legitimate, the payee or merchant is authentic, the device or session has not been compromised, and the user has approved the specific transaction being executed. Without that chain of assurance, faster rails simply move trusted money to untrusted destinations more quickly. This is where wallet-based digital identity and cryptographic assurance become foundational. They allow individuals and businesses to prove who they are, and who they are interacting with, without repeatedly exposing unnecessary personal data. The result is not just stronger verification, but a more privacy-preserving model for trust.Crucially, stronger verification does not have to mean more friction. The goal is not to slow payments down, but to remove uncertainty from the experience. Identity security should work quietly in the background, binding the right user, device, merchant and transaction together at the point of approval.This also reframes a long-standing tension in financial services: the perceived trade-off between privacy and fraud prevention. With new identity security solutions, that tension melts away. By minimising data exposure while strengthening authentication, payment providers can make privacy and security complementary features of the same system. Lessons in scale There are valuable lessons to draw from markets that have already scaled domestic payment systems. India’s UPI and Brazil’s Pix show how quickly well-designed payment infrastructure can achieve mass adoption when it is interoperable, accessible and low-friction.But scale brings its own pressure. In high-volume, real-time environments, small weaknesses in verification can be amplified quickly. As payment systems become more central to everyday life, they also become more attractive targets for fraud, social engineering and account compromise.For the UK and Europe, the lesson is clear. Identity assurance should not be retrofitted after adoption. It should be embedded at the infrastructure level before new payment models reach scale.Sovereign systems give regulators, banks and market operators the ability to define stronger rules for how identity, consent and transaction data are handled. They can create standards that support competition and inclusion while giving consumers greater confidence in who they are paying and how their data is used. Ultimately, sovereignty is not a finish line. It is a means to build better systems that are more resilient, competitive and trusted.But control over infrastructure is only part of the answer.The future of payments is defined by whether people can trust every transaction they make. That starts with identity.No#IdentitySecurity #PaymentsGonzalo AlonsoDitto 08 Jul, 2026
