Cartesi – Why Off-chain decentralized computation

Valucop Global held a whatsapp webinar/Interview with the Lead, Cartesi Nigeria Helen Imah. She enlightened us on everything about Cartesi and the amazing projects they are pulling throu.

Tell us a bit about yourself. How did you start your crypto journey?

 Okay great. I’m Helen IMAH by name, a Computer Science graduate and Lead at Cartesi Nigeria. The first time I came across Bitcoin was in 2015 while surfing the Internet that happens to be my most prized hobby, then I was still an undergraduate.

 I read related articles and watched YouTube videos that got me started on my blockchain/crypto journey.

Fast forward, in the Q2 of 2017, I became an ICO (initial coin offering) investor, from there I moved to crypto trading and now I represent notable blockchains as brand ambassador.

It has really been an interesting journey so far.

Can you shed some light about Cartesi and why was the project started?

 Cartesi is building an operating system for DApp.  The project enables complex and intensive computations to run in a Linux environment, outside the blockchain, without compromising decentralization.

 Cartesi aims to make DApps significantly more powerful, cost-effective, easier to develop, and portable. At Cartesi, we empower DApp developers by helping them build products that are ever more compelling to users, bringing us all closer to a future in which decentralization becomes less burdensome.

For the second part of this question, Cartesi is being developed so as to close the gap between centralized and decentralized applications, both in terms of possibility, convenience and security.

Now to the theme of the day. Why off-chain Decentralized Computation?

 Interesting, thanks for coming up with such a question. No software application is built in isolation. Mainstream mobile/desktop/web Applications today depend on multiple software dependencies that took decades to mature on operating systems like Linux.

 Cartesi brings all these software infrastructure to blockchain applications.

 Whereas without Cartesi, blockchain applications cannot use mainstream software, libraries and services, unless they sacrifice decentralization in some way. But, there’s the second problem. Besides being hampered by insufficient software infrastructure, decentralized applications also suffer tight on-chain processing limits.

So, they can hardly offer a compelling alternative to mainstream centralized applications. They are often hard to build, being clunky and limited for developers and DApp users.

 Cartesi solves these three problems by:

  • Offering developers the software and tools supported by a full Linux OS;
  • Moving off-chain all the heavy computation over large amounts of data, that blockchains cannot do;
  • Offering services and a token economy that allows users to securely rely on the network and remain free from inconveniences of blockchain tech (e.g. slow confirmation times, requirement to remain online to resolve disputes, and others).

To our 4th question. Tell us a bit about the Cartesi team and tell us about some key members of the project.

Okay. The most important asset for Cartesi is a team of very strong researchers and engineers extremely excited to create and implement novelty in the blockchain space.

A highlight of the founders can be seen below:

  • Our CEO, Erick de Moura (CEO) is a technical leader with deep experience in system design and development. Erick’s specialities include software architecture, process definition, and execution. As a consultant, developer and business owner before Cartesi itself, he has dedicated 20 years to the software industry and was pivotal in the success of several tech companies in different verticals such as Fintech, Healthtech, E-commerce, and Infrastructure.


  • Augusto Teixeira, PhD (Chief Scientific Officer)

An expert in computer graphics, image processing, and massive parallelism (GPGPU), was granted 3 patents, published 36 articles and scientific papers, and received more than 1900 citations.



  • Colin Steil (COO)

Execution master with years of experience in community and business operations across the globe. Colin is a previous venture capitalist and start-up founder with a speciality in the Asian ecosystem. Colin first got involved in blockchain in early 2017. He began working with blockchain technology, crypto exchanges and ICO projects in the venture capital industry.

Could you please tell us the vision of Cartesi is in Nigeria

 Okay ma’am.  Cartesi Nigeria is a subset of Cartesi project. We have a clear vision and goal; closing the gap between centralized and decentralized applications for Nigerians in terms of power, possibility, convenience and security.

We have a digital presence in Nigeria via social media both on Twitter and Facebook which is one step to gaining awareness in the country. So, we really hope to have an active community in this part of the world.

I will be sharing our community links before the end of this event and tell you about an ongoing program that Cartesi has just launched and Devs from any part of the world can participate including Nigerians.

 Ensure to wait till the end of this event so as to have the full details, there will even be a reward for winners!

So to the last question of the first session…

What is your view of the present crypto market, are we in a bull or bear market?

 A very necessary question. The crypto market has gained more awareness and of course adoption during this pandemic lockdown most especially in our dear nation and Africa region. A lot of media talked about this. I feel many seize the lockdown opportunity to learn stuff online, I guess a greater % of these people came in to learn about blockchain and cryptocurrency

 The crypto market did experience some bullish movements last month but obviously not the main bull run. Let’s hope for better.

Sure we have to hope, personally I look forward to the recovery of the market

Thank you so much ma for your amazing replies…
