BACKGROUND

Please describe your company and your position there.

I am the CTO of the Energy Web Foundation. Energy Web (EW) is a global nonprofit organization accelerating a low-carbon, customer-centric electricity system by unleashing the potential of blockchain and other decentralized technologies. EW focuses on building core infrastructure and shared technology, speeding adoption of commercial solutions, and fostering a community of practice.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire 482.solutions?

The EW-DID library implementation confirms to the requirements specified in the DID Specification published by the W3C Credential Community Group. The aim of the library is to : provide an abstraction layer to manage and interact with DIDs and Verifiable Claims on Energy Web Chain enable EW Member organisation to adopt or/and implement different DID methods for more info see 

What were your goals for this project?

the library must be easy to use on the server and in the browser. It shall use cryptography in a smart way to enable secure and trustworthy claims management

SOLUTION

How did you select this vendor?

We interviewed the developers and decided to give it a try. After 2 successful 2 week sprints we decided to extend our collaboration. That is how we select all our vendors. It is easy and less costly than lengthy selection processes.

Describe the project and the services they provided in detail.

DID Flow The following will describe the process of both Public and Private Claim generation and verification. Private claims involve ZKP to obfuscate the content of claim fields from third parties (verifiers). Detailed description of ZKP Protocol

Security considerations: The Schnorr identification protocol has been proven to satisfy the following properties, assuming that the verifier is honest and the discrete logarithm problem is intractable (Stinson, 2006).

  1. Completeness - a prover who knows the discrete logarithm is always able to pass the verification challenge.
  2. Soundness - an adversary who does not know the discrete logarithm has only a negligible probability (i.e., 2^(-t)) to pass the verification challenge.
  3. Honest verifier zero-knowledge - a prover leaks no more than one bit of information to the honest verifier: whether the prover knows the discrete logarithm.

The Fiat-Shamir transformation is a standard technique to transform a three-pass interactive Zero-Knowledge Proof protocol (in which the verifier chooses a random challenge) to a non-interactive one, assuming that there exists a secure cryptographic hash function.

Since the hash function is publicly defined, the prover is able to compute the challenge by itself, hence making the protocol noninteractive. In this case, the hash function (more precisely, the random oracle in the security proof) implements an honest verifier, because it assigns a uniformly random challenge c to each commitment (g^v or G x [v]) sent by the prover.

This is exactly what an honest verifier would do. It is important to note that in Schnorr's identification scheme and its non-interactive variant, a secure random number generator is REQUIRED. In particular, bad randomness in v may reveal the secret discrete logarithm.

Basic Flow of the Protocol Let g be a generator of a cyclic group of prime-order q. L e t f b e t h e f i e l d v a l u e o f t h e c l a i m . The goal is to convert the field value to a keypair, whereby the obfuscated field value represents the private key (secret), and the public key can be shared with the verifier. To generate a keypair, Alice would take the field value f and concatenate with a random integer (salting). Salted value will be then hashed to a random integer a between 1 and q. The keypair is computed as follows: PKA = g = a mod q, SKA a PK can be published to the world.

To prove the verifier that the secret associated with the public key is known, the following n o n - i n t e r a c t i v e protocol is performed: A l i c e g e n e r a t e s a r a n d o m k i n t h e r a n g e 1 , … , q T h e v a l u e h = g m o d q i s c a l c u l a t e d . k T h e c h a l l e n g e c i s d e f i n e d a s f o l l o w s : c = H A S H ( g | | o t h e r P u b l i c D a t a ) k Value s = ac + k mod q, along with PK and is sent to the verifier.

Rhe last step of the protocol is verification. The verifier reconstructs the challenge c using publicly available information. The verifier trusts the prover, if the following holds: g s = P K * A c h m o d q g = * ac + k (g ) a c g mod q k g ac + k = g mod q ac + k Suggestion for Library Used SHA256 with secp256k1 elliptic curve can be used, as javascript libraries are readily available and t h o r o u g h l y t e s t e d .

For both the hashing algorithm and elliptic curve math sjcl (Stanford Javascript Crypto Library) can be used, as it implements both. References Stinson, D., "Cryptography: Theory and Practice", 3rd Edition, CRC, 2006. 

What was the team composition?

EWF Team members * Software architect * CTO 482 solutions team members * 2 senior full stack engineers

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

it allowed us to successfully complete another project which was depending on this functionality

How was project management arranged and how effective was it?

project management was performed from EWF. It was easy and seamless to work with 482 staff as they are proficient in participating in online meetings. We are a decentralized, remote first organization which was a perfect fit

What did you find most impressive about this company?

Their level of technical expertise and know-how was really beyond our expectations. They provided many solutions we would not have thought of. Namely the zero knowledge proof for the selective attributes disclosure on private claims

Are there any areas for improvement?

I found the collaboration to be great.

From the beginning, we worked with three of their team members including an IBM developer. By the end of the project, we were working with six people in total.

How did you come to work with 482.solutions?

We asked friends and other business leaders for recommendations. We then found reviews for 482.solutions online. They have a good reputation and are trustworthy.

How much have you invested with them?

We spent about $50,000.

What is the status of this engagement?

We began working together in April 2018 and the project is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

Although the project is still ongoing, I’ve been able to use the platform. They take a very detailed approach to every client and each project. Their team will take a task, and deliver a high-quality product no matter what. When we need help, they offer solid advice. Not only do they listen to what we want, they tell us how we could be better. They’ve finished all the tasks on time.

How did 482.solutions perform from a project management standpoint?

We had meetings with them almost every week for the first three months of development. At later stages, we met about every two weeks. We generally communicate by phone, email, and Trello. When we ask them for advice or to make changes, we just need to call and ask. We also are able to talk to them before we make any payments.

What did you find most impressive about them?

They’re always very prepared. Before we started working with them, we had several meetings in which they brought a lot of materials, samples, case studies, and they always tell us what will be best for our business.

Are there any areas they could improve?

The price was a little high.

Do you have any advice for potential customers?

Take into account the time it takes to create proposals and prepare. It can be the difference between 200 and 300 hours and will help you calculate the cost and establish a reliable time table.
