Blockchain Identity & Reputation Systems

One of the many important features of DREAM is its utilization of blockchain technology to provide proof of identity, qualifications, and achievements.

This article provides some background on the current state of the industry, and more depth as to how DREAM will implement this feature on its platform.


The difficulty of proper online identity authentication has plagued the Internet for a few decades. Social media has compounded this problem. For example, it’s a well established fact that Facebook alone has hundreds of millions of fake accounts/identities.

If we consider the remaining social media and messaging platforms, the number of fake identities could easily be ten times that. To further complicate the problem, many of these fraudulent accounts are responsible for false reviews, fake leads, bogus subscriptions, etc.

Reputation systems typically rely on centralized owners monitoring their platform and are reasonably capable of reducing fraud on those platforms. Unfortunately, those claims are locked to that platform, leading to interoperability issues.

The Current State of Play

There have been many unique attempts to solve this problem in the blockchain community. A few prominent projects that have recently sunk their teeth into it include:

  • Uport — a self sovereign identity system

  • Civic — a secure identity ecosystem for business and individuals

  • Blockverify — a blockchain based counterfeit solution

  • SelfKey — verification and notarization of IDs

  • Nekti — an interoperability solution for identities

While most have focused on “Identity Solutions”, a few have taken on solving reputation related challenges:

  • Kudos is working on allowing business in service based industries to allocate incentives to its users and create a rating system based on the data

  • CredibleToken is working on maintaining the credibility of mobile devices and creating a more trusted network of smartphone devices

Understanding Identity and Reputation Systems

In order to understand the implications, we need to unpack a fundamental term, i.e. what exactly is “Identity”? Depending on the circumstances, some aspects may be more valid than others. If you are traveling, a passport is useful, but if you are playing a team sport, your clothing is a better identifier.

If we dissect this, it becomes clear that “Identity” is a representation of “Claims” — claims made by an entity that are verifiable within an ecosystem. A similar extension can be applied to “Reputation Systems” where within a contextual environment, an entity could have a 5 star or a 1 star reputation. Verifiable claims are at the core of “Identity and Reputation Systems”.

Once you realize this, the applications become nearly boundless. Notarized ID claims, passports, skill endorsements, feedback ratings are only the tip of the iceberg.

Smart contracts allow for both human and machine identification. Computer systems, mobile devices, and any other smart IoT device can be presented with identification, and specific tasks can then be executed on external commands.

DREAM Ecosystem

Even with the rapid innovation in the blockchain industry, mammoth scalability issues still persist with decentralized, distributed systems. Writing to blockchain remains expensive, as storage is still a problem.

In the world of Web 2.0, highly scalable solutions like AWS, cloud storage and data centers are convenient and cheap, creating a challenge bringing consumers on board decentralized storage systems (however, the jury is still undecided on that matter).

The DREAM ecosystem looked at these challenges and made a decision to solve one of these core blockchain issues through the DREAM protocol. DREAM’s roadmap includes implementing the ERC725 standard to bring authenticity to freelancers’ identities.

Reputation system interoperability is another big issue. It’s difficult to transfer reputation values from closed systems. DREAM tackles this problem by remaining blockchain agnostic and creating a solution where participants can easily carry their reputations from DREAM to other gig/freelance platforms. The majority of solutions currently lack this feature, and DREAM has formed strategic partnerships with key “Identity and Reputation” system management leaders to meet this challenge.



If 2017 was the year of the ICO… Then 2018 is the year of the build-out. In a few years time, we will be using a handful of these decentralized applications and continue innovating. As we continue collaborating and building partnerships to solve these important issues, we build a stronger future and a bigger DREAM. We'll close here with a few words from one of our advisors:

I am happy to help DREAM to make their blockchain reputation and identity system open and aligned with standards such as the ERC725 blockchain identity I proposed. I encourage collaboration within the community and the different platforms. Open identity and reputation systems are essential to give back control to the user, increase trust and transparency, while allowing users to take their data everywhere, and outlive any platform.Fabian Vogelsteller, Ethereum Developer, ERC20, Founder of Lukso

The DREAM platform isn’t just another untested beta program on a white paper… It’s live and being used right now to hire blockchain professionals. The token sale will enable DREAM’s innovative team to take DREAM to the next level by integrating A.I. and incorporating our platform token.
