# The YouGovern Secure Blockchain-Based Self-Sovereign Identity (SSI) Management and Access Control
## 6 Discussion and Future Work
### Future Extensions  
SSI represents a transformative and forward-thinking approach to managing individual digital identities, solving many issues inherent in traditional identity management systems in terms of regulation, technology, and security. By integrating digital wallets and decentralized ledger technologies such as blockchain, YouGovern allows individuals to control and manage all of their digital assets independently, with enhanced privacy and sovereignty. This new model of identity management not only facilitates fast and secure access to digital versions of identity documents, academic diplomas, and property titles but also allows individuals to manage tokenized fiat currencies and cryptocurrencies. Blockchain networks provide cryptographic proofs of the existence and ownership of digital credentials and assets, which increases the trust, interoperability, security, and efficiency of electronic transactions while maintaining privacy. Considering the regulatory environment, there is a pressing need to develop and update policies around electronic transactions and data privacy. Despite significant advancements, many regions, including Latin America and the Caribbean, still lack comprehensive regulations on data protection. Thus, it is crucial to focus on these areas to provide a secure framework for the deployment of SSI solutions. Moving forward, organizations such as ISO, ITU, NIST, and the European Union predict rapid growth in activities surrounding self-sovereign identity. The likelihood is that soon, management of all digital assets could be done through a mobile wallet, using blockchain to ensure the accuracy and security of transactions. This technological shift presents a significant opportunity for both governments and private sector entities to take proactive steps towards adopting and implementing SSI solutions. Although YouGovern is currently deployed on BSC for its low-cost and high-speed capabilities, we acknowledge that BSC's Proof of Staked Authority (PoSA) model introduces partial centralization due to its limited validator pool. This may seem to challenge the principles of SSI. However, YouGovern's architecture is designed to be portable across different blockchain platforms. Future versions of the system may migrate to more decentralized infrastructures such as Ethereum 2.0 or Hyperledger Indy. Furthermore, the system architecture ensures that identity ownership and control remain user-centric through smart contract logic, mitigating the risks posed by infrastructure-level centralization. In terms of decentralization, BSC operates with a limited number of validators (21 active) under the PoSA model, introducing risks of validator collusion. In contrast, Ethereum's Proof of Stake (PoS) involves thousands of validators distributed globally, significantly reducing the risk of coordinated manipulation. Hyperledger Indy, although permissioned, distributes trust across multiple governance entities with explicit policies for DID management. While BSC enables rapid prototyping, future versions of YouGovern aim to support interoperability with other platforms through DIDComm and Verifiable Credential frameworks, thereby reducing reliance on a single blockchain and enhancing trust and resilience. \begin{table}

Unlike centralized systems, where identity can be revoked and reissued by the provider, SSI systems must embed user-driven recovery. In YouGovern, we plan to implement a social recovery mechanism that allows users to assign trusted guardians who can jointly approve key restoration.
