How MiCA/TFR can accelerate the adoption of Self-Sovereign Identity in Europe

published on 30 May 2023

The MiCA/TFR regulation, set to take effect in 2024, marks a significant milestone in the European Union's efforts to regulate cryptocurrency transactions. Under this groundbreaking law, identification will be required for a growing number of crypto transactions, compelling businesses and users within the web3 ecosystem to seek innovative methods of ensuring compliance. While this regulatory shift poses challenges, it also presents a unique opportunity for the widespread adoption of Self-Sovereign Identity (SSI) solutions.

Self-Sovereign Identity and Web3 principles

SSI, also referred to as decentralized identity, aligns perfectly with the core principles of web3, which emphasize decentralization, ownership, and privacy. In an era where centralized databases are increasingly vulnerable to data breaches and privacy concerns, SSI empowers individuals to manage their data through “verifiable credentials”, a decentralized, highly secure, tamper-proof, and privacy-preserving format.

The growing importance of SSI in the EU 🇪🇺

The introduction of MiCA/TFR necessitates web3 businesses to explore secure and efficient methods of users' identity verification. This regulatory push has the potential to open doors for SSI to become the trusted and reliable solution within the web3 ecosystem. Moreover, the European Union is already embracing SSI as the new standard for digital identity through initiatives like the European Blockchain Services Infrastructure (EBSI).

The EBSI, an initiative by the European Commission, aims to leverage decentralized identity standards defined by the World Wide Web Consortium (W3C) for various use cases, including passports, educational credentials, social security, and more. By progressively adopting SSI, the European Union is actively promoting a more reliable and user-centric approach to digital identity management. Conformant wallets like Altme will play a crucial role in this regard, ensuring compatibility and compliance with the standards defined by the European Union.

How Decentralized Identity can enhance users privacy and data ownership 

One of the key advantages of SSI in the web3 ecosystem is its ability to enhance privacy and data ownership. With SSI, individuals have control over their personal information and can selectively disclose only the necessary data for specific transactions or interactions. This level of granular control not only mitigates privacy concerns but also minimizes the risk of identity theft and fraud.

By using decentralized identity wallets, web3 users can benefit from:

  • Full control and ownership of their digital identity and personal data.
  • Privacy-preserving features such as selective disclosure and zero-knowledge proofs (ZKP) to share only the necessary information when required and protect their privacy.
  • Improved user experience: verifiable credentials are reusable, making it super convenient to prove identity, age, diploma, and more.
  • Compliance with regulations (MiCA/TFR).

How web3 projects can benefit from Decentralized Identity (DID)

SSI also offers benefits to businesses operating in the web3 space. By utilizing SSI solutions, these businesses can streamline customer onboarding processes, reduce reliance on centralized identity providers, and improve user trust. SSI's tamper-proof nature provides increased security and can help combat fraud and impersonation attempts, thereby safeguarding both businesses and their customers.

By leveraging self-sovereign identity, web3 businesses and protocols can benefit from :

  • Faster user onboarding and reduced verification costs: verifiable credentials are reusable and instantly verifiable, streamlining the onboarding process and reducing costs.
  • Compliance with MiCA/TFR, GDPR, KYC/AML, and age verification rules: decentralized identity enables businesses to adhere to various regulations easily.

2 majors use cases for Decentralized Identity in web 3 

Let's delve into some specific use cases where decentralized identity can revolutionize the user experience:

  • KYC/AML compliance: Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations are essential in the cryptocurrency space. Self-sovereign identity wallet simplifies the KYC process by enabling users to securely verify their identities once to obtain reusable verifiable credentials. These credentials can be easily shared with different platforms and services, eliminating the need for repetitive identity verification processes.
  • Age verification: In industries such as decentralized finance (DeFi) or web3 gaming (GameFi), age verification is crucial to ensure compliance with legal requirements and protect vulnerable users. SSI provides a reliable solution by allowing users to easily prove their age using verifiable credentials. This streamlined process ensures a seamless user experience while maintaining privacy and security.

The power of Decentralized Identity wallets 

Decentralized identity wallets are poised to be game-changers in this evolving landscape. These wallets, built on DID/SSI principles, enable users to store and manage their verifiable credentials securely. They act as a single source of truth for individuals' digital identities, allowing seamless verification across different services and applications. Decentralized identity wallets empower users with full control over their data and enable them to interact with various entities while preserving their privacy.

The Altme wallet is a self-sovereign crypto-identity wallet designed to empower web3 users and businesses by providing a secure, privacy-preserving solution for identity management. With Altme, users can manage their identity (Verifiable ID) and crypto addresses in the same wallet, making it incredibly easy to link crypto addresses ownership to an identity (MiCA/TFR compliance).

With Altme, users can enjoy full control and ownership of their personal data, while businesses can leverage the benefits of faster onboarding, reduced verification costs, and seamless regulatory compliance.


In conclusion, the MiCA/TFR regulation presents a pivotal moment for the adoption of self-sovereign identity in the European Union's web3 ecosystem. By aligning with web3's principles of self-sovereignty, ownership, and privacy, DID/SSI offers a secure and privacy-preserving approach to digital identity management. And with the European Union already embracing SSI through initiatives like the European Blockchain Services Infrastructure (EBSI), the stage is set for the widespread adoption of decentralized identity solutions, empowering individuals and businesses alike in the evolving digital landscape.
