Among the variety of non-financial use cases, blockchain technology can be applied to identity applications in areas such as digital identities, passports, e-residency, birth certificates, wedding certificates, IDs, online account logins, etc. Creating an identity on blockchain can give individuals greater control over who has their personal information and how they access it.

By combining the decentralized blockchain principle with identity verification, a digital ID can be created to act as a digital watermark which can be assigned to every online transaction of any asset. Here are some of the pioneers in building blockchain-based identity management and authentication solutions for cross-industry applications:

2WAY.IO effectively transforms public nodes into private nodes by adding a permissions layer. Private nodes can connect information silos & secure communication channels. They’re user-in-control (privacy-by-design & security-by-design) and require no trade-off between security and UX. These systems are both trusted third-party- and blockchain-agnostic; they only require an intermediary or blockchain when both parties agree to add one to their interaction.
