Blockchain

How evan utilizes

Permissioned Blockchain Technology

All evan apps and products transmit user data through a privacy preservation platform that enables secure data transmission and ensures the appropriate usage of the data collected. Whether the connection is to emergency services, calls to friends, or to professional/family members that administer naloxone – all parties using the app are protected within the evan Blockchain.

What is Different?

The majority of online platforms or smart solutions (apps) resort to a ‘disclaimer’ where the user ticks a box, providing access to their data. However, in an emergency, a user may not be in a position to check this box with conviction. The user may refute that informed consent later, ending with legal disputes. The disclaimer can also be abused by an unknown person or proxy or be intercepted by unwelcomed third-parties during transmission.

Introducing

The evan Blockchain

The evan blockchain utilizes permissioned blockchain technology and is designed with the active participation of users, support groups, volunteers, as well as emergency services or health providers. During the setup process, users and a selected number of people accepted by the user are integrated in the blockchain. The ‘informed consent’ is enabled when the users accept the clear number of proxies, while they are fully aware, eliminating the need for a disclaimer and preventing future disputes. When the data is accessed (for instance, when someone uses the app to get in), all parties in the blockchain get notified.

This makes any attempts to abuse the system almost impossible.

Benefits of The evan Blockchain

By going through a blockchain enabled security layer, all users pre-consent their information to be collected and appropriately transmitted to emergency services, friends or families, under the correct circumstances. In addition, they are also consenting for this data to be used by us for innovating future harm reduction and recovery solutions enabled by public health authorities.

Quality of Health Data

The immutable property of blockchain improves the quality of health data stored on it. All data is time-stamped, encrypted, and appended in chronological order. As it uses cryptographic keys, identity and privacy is protected. No one can change it, refute it, or hack it without the knowledge of all those in the blockchain.

Transparency

Transaction histories are transparent as Blockchain has a distributed ledger with all network participants sharing the same documentation. To change a single transaction record would require the alteration of all subsequent records and the involvement of the entire network. Thus, data on a blockchain is more accurate, consistent, and transparent.

Appropriate Usage

Users need to be confident that their data is in their control and privy to how it is being used. The ability to detect if there is a potential misuse is enabled by blockchain using cryptography protocols and well-defined smart contracts.

Improved Traceability

Whenever an exchange occurs on the blockchain, a complete audit trail is available. This historical transaction data increased traceability, and can help to verify the authenticity of assets and prevent fraud.

No Middle-Men

With blockchain, there is no middle-men, you can simply trust the data on the blockchain. You also do not have to review any documentation because everyone will have permissioned access to a single, immutable version.

Security

After a transaction is approved, it is encrypted and linked to the previous transaction in the blockchain. As information is stored across a network of computers instead of on a single server, it is very difficult for hackers to compromise the transaction data. Blockchain ensures security of data because instead of storing the information in private servers, which can be breached at any time by a hacker, the information is hashed through unique identifiers, before being transferred to the blockchain. The information is encrypted so private information would be more secure during communication.

Increased Efficiency & Speed

By streamlining and automating processes with blockchain, transactions can be completed faster and more efficiently. Since record-keeping is performed using a single digital ledger that is shared among participants, you don’t have to reconcile multiple ledgers — making it easier to trust each other without the need for numerous intermediaries.

On the Horizon

In the next level of our development on smart apps, our integrated AI will be ‘sensing’ the state of the user and triggering an alarm that then transmits user data without their intervention. A pre-informed consent is then necessary upon download before the app can be in-use, which is enabled through the permissioned blockchain!
