Scrypta and Digital Identity

In our every day increasingly digitized world, one of the biggest concerns for businesses and public bodies is to know precisely the real identity of the users behind their computers. In the mean time it is fundamentally important to everyone to protect own online identity.

Since data can define people, there have been many attempts to develop technologies to accurately determine who the user is and to find out personal details (name, address, age) as well as other traits such as status, health, hobbies, etc. That’s why Digital Identity has a significantly important role and it is becoming crucial to intensify security in all interconnected environment.

The common problem of all centralized digital databases lies in the identification methods, based primarily on an intermediary part designated to verify the authenticity of each identity. This process produces excessive service costs and gives the responsible body full control and the decision power on which service providers are authorized to utilise the verified identity. In this scenario users must rely on central agency employees that they would transfer digital identities only to the authorized parties.

The immutable and distributed nature of the Scrypta blockchain, on the other hand, can be used to identify and manage digital identity by making improvements on two fronts.

Firstly, it eliminates the need to go through a third party, because the data is stored in large public registers controlled by a network of users. Identity records reside redundantly in different nodes, resulting in a reliable and public source of truth. Each user is a certification authority for himself, deciding who to rely on basing on the objective evidence provided to him. Service costs involved are thus reduced. Furthermore, the use of cryptographic hash functions override any possibility of revealing private and sensitive information about themselves in contexts in which it is not relevant to the activity in progress.

Secondly, Scrypta’s blockchain technology makes digital identity more reliable and secure as it can be freely integrated into any service where the identity holder and counterparty agree to use it, making online reputation a lot more pervasive and meaningful and facilitating users to trust documented credentials.

As a practical example, consider a company or an entity releasing a private key to each user only after verifying their identity. As an outcome any user action is documented, similarlywith the certified email (PEC). The database information protection is entrusted to public key cryptography.


Public-key cryptography works with a pair of keys, a public and a private one, used to identify users and allowing to exchange data in a protected and secure way. Users are identified in the blockchain by a string of characters, called the “address” derived from their public cryptographic key. This system allows you to keep and protect online identities allowing users to access their accounts without using their passwords.

Lyra NFC Card by Scrypta (beta)

Scrypta is developing an identity card with NFC technology — near-field communication — (see Roadmap), which integrates the public key system described above containing the user’s identity. Through NFC you can quickly synchronize data between two devices, even if completely different from each other (specific readers, mobile phones, etc. ..).

If you think that the automation process is now unstoppable and more and more businesses and economic sectors are moving from analogic to digital, then we can guess that NFC technology combined with the blockchain can open up many possibilities and many application scenarios. Scrypta represents a solution that guarantees a safe and efficient outcome.
