🎤 AMA Session With Bruno Maia, Head of Business Development, & Joe Nance, Director of Cartesi Labs

Cartesi is an off-chain decentralized computation platform. It is unique because it allows decentralized applications to be run on Linux in a way that’s verifiable by the blockchain. Complex processing can be executed off-chain free from blockchain’s computational limits and corresponding fees.

Let’s dive in, shall we?

Everstake: We are glad to meet: Bruno Maia — Head of Business Development & Joe Nance — Director of Cartesi Labs. Can you introduce yourself to the Everstake community? What is your background and where did the idea of ​​creating Cartesi come from?

Joe Nance: Greetings from Taiwan, everyone! I’m Joe; originally from the US but based in Taipei for the past 5 years or so. I got involved in blockchain back in 2017 and immediately was enamored with smart contracts. This was the catalyst for my odyssey as a blockchain developer, as I built and led a startup which launched a dapp focusing on exercise and brand loyalty by merging IoT and Ethereum. Shortly after, I joined Binance to lead investments in the M&A team as well as Binance Launchpad/pool and Binance Labs.

The intersection of business and technology is where my interest lies, and I am so excited to have joined Cartesi as the Director of Cartesi Labs just over a month ago. I’m really interested to see how people are leveraging this awesome technology. Furthermore, I’m excited to discover those building on it.

Bruno Maia: Hey Joe good to have you here with me running this fantastic AMA for Everstake community! Hi all thanks for having me here today.

I’m happy and excited for our AMA today as part of our year closing events. I’m Bruno Maia, Cartesi’s Head of Business Development.

I come from the Telecom industry where I worked for more than 15 years as a strategic consultant for Qualcomm. Back in 2016 I started my exploration into the blockchain world; initially as an enthusiast and investor, but it was love at first sight. I knew this new segment would represent the future, with vast implications and opportunities, so in 2018 I moved fully into the blockchain business and changed career paths. It was a very fortunate choice and I’m incredibly happy with it. My path into Cartesi came in 2020 when Erick, our CEO, who I have known for years, invited me to lead the business development group. He believed my international consulting background, technical knowledge and understanding around the blockchain/crypto market would be of great value for Cartesi.

Cartesi was created back in 2018 when the founders were discussing a potential project to deliver a decentralized AI marketplace. The concept evolved until they figured out that the overall infrastructure required was much more powerful and far-reaching than a simple AI marketplace. From there, the Cartesi tech and tools have been under development and constant evolution, always aiming to solve the inherent limitations of blockchain scalability and infrastructure while bringing blockchain its first full operating system; a Linux OS.

Everstake: Awesome, thank you! Can you briefly describe what Cartesi is and what important problem is trying to solve?

Bruno Maia: Thanks for this very important question!

Cartesi is the first OS for blockchains, our Layer-2 solution integrates Linux and standard programming environments to blockchain. This allows developers to code scalable smart contracts with rich software tools, libraries, and services they are used to. Cartesi bridges the gap between mainstream software and blockchain, welcoming millions of new startups and their developers to blockchain by bringing Linux to blockchain applications. Cartesi combines a groundbreaking virtual machine, optimistic rollups, and side-chains to revolutionize the way developers create blockchain applications.

I hope that clarify the key problems we are addressing.

Everstake: Very, very interesting. My next question is: Can you name your competitors and what are the main competitive advantages of Cartesi?

Joe Nance: We are in a very distinguished position. While there are other projects also aiming to scale blockchain capabilities such as Arbitrum, Optimism and other solutions based on ZKRollups; Cartesi also does this through rollups, however, we are not only scaling computation and transaction costs, but we are also bringing an entire Operating System onto blockchains.

We believe this is a game changer for both mainstream developers who would like to get into blockchain, and also existing blockchain developers who would like to build more complex applications. For example, one of our team members will release an interesting article this month about how can we truly tackle the content scalability problem in Ethereum.

Everstake: Thank you for your answer! What prompted you to announce Everstake as your first validator? How important is your partnership with Everstake and how can it scale?

Bruno Maia: Very nice one! Everstake and Cartesi have a long partnership. Let me go through the details.

Everstake has a very good reputation as an enterprise-grade blockchain infrastructure provider with a proven track record of operating nodes for the most relevant blockchain projects such as Elrond, Cardano and others. Since the earliest days of Proof-of-Stake networks, Everstake has been building up the necessary infrastructure to support staking on PoS systems. Dev-ops, front-end development, and blockchain development expertise combined have made Everstake highly professional and able to offer enterprise-ready industry-grade services.

Moreover, Everstake has been part of our staking community and has been an active contributor to our system, providing both recommendations and testing. Everstake was part of the mainnet beta and helped thoroughly test and support our PoS network’s delegated staking feature from the beginning. Having Everstake as one of our earliest pool managers on mainnet was a natural path of this already successful partnership.

Everstake: Wonderful, hope for fruitful cooperation in the future where we can grow together.

Let’s move on to the community already sent questions. The best ones have been selected for this AMA. The first one is: How can I create smart contracts with the Linux-compatible software components offered by Cartesi? What improvements does this protocol offer over Solidity? Is it easier and more intuitive to make a smart contract using Linux?

Joe Nance: That is a very good question. Our Virtual Machine (VM), which boots an entire Linux Operating System (OS), gives you the freedom to choose any programming language or software you are comfortable with.

Once you have defined the programming language or software stack that most suits your needs, it’s time to organize your DApp architecture. The architecture is defined by organizing your code in the front-end and back-end. Your back-end code will have all the logic required to be decentralized. Once you determine that, you will code your back-end to launch into our VM, which runs on our Node Validators. At this moment, you will have your DApp launched and connected with your front end.

Of course, this is a very quick overview and “flyover” of the process. In the coming weeks we are planning to publish several articles which aim to explain the exact DApp development lifecycle inside of Cartesi’s tech. Stay tuned!

Does that make sense?

Everstake: Yes, sir! Very helpful, thanks!

Our next question is: If the node fails due to node downtime, offline or insufficient ETH funds, can I still generate blocks and get rewards?

Joe Nance: If your node is unavailable or without enough ETH to produce a block, it will likely miss the opportunity to produce that specific block and its related rewards.

That’s why it is important to properly choose a reliable pool manager who operates their node appropriately, resulting in a good track record.

It’s also important to note that Noether (our side-chain and PoS system) has no slashing or risks to the principal resulting from node unavailability.

Everstake: Awesome, thank you!

Our next question is: Does Cartesi have a plan for the next generation of Metaverse?

Bruno Maia: Metaverse is an amazing and inspiring topic.

I believe Cartesi is very well positioned to be used as a preferred tool for the next generation of blockchain applications. Not only Metaverses, but also for general DApps.

Our capacity to offer substantial flexibility on programming languages and existing software, while leveraging an entire Linux OS with all its tools; such as compression/decompression of files as well as other libraries/database tools/or services, together with the scalability of computation and transactions, makes our technology future-proof; thus perfectly aligned with what is coming next.

Everstake: Very interesting info!

The next community Q is: Why do you claim Cartesi is the first operating system on the blockchain?

Joe Nance: There have been several projects in the past that claim a blockchain itself is an “operating system,” however this is not accurate. 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 this software infrastructure to blockchain applications; a real OS.

Whereas without Cartesi, blockchain applications cannot use mainstream software, libraries and services, unless they sacrifice decentralization in some way.

Everstake: Did you hear guys? That’s why Cartesi is unique. 🚀

Our next question is: Does Cartesi see it’s poker engine being used for gaming in the future? Similar to unreal engine?

Bruno Maia: We indeed are developing a poker heads-up MVP to showcase how powerful and flexible our technology is.

We see Cartesi being largely used by the game industry in the future but not replacing unreal engines.

Cartesi will allow a strong rise on what can be developed that is totally decentralized, not only due to its massive computational scalability but also with the flexibility of program languages and software.

We have seen recent cases that show how important decentralization is, from amazon MMORPG issues through Tezos’ NFT collapse, showing the demand for further decentralization. This demand will be even higher as stakes involved in those applications and games get bigger.

Having said that, it is possible to use an unreal engine alongside Cartesi, if the logic is decentralized; for example building a tournament within an unreal game.

Everstake: Amazing, very amazing!

What makes Cartesi unique in the space of layer-2s and how it plans to distance itself from the competition?

Joe Nance: We are the first real blockchain OS, firstly.

Cartesi is bringing the first Linux OS to blockchains. This is a game changer in terms of mainstream adoption, as it will offer millions of developers a very common and friendly platform on which they can make their transition into the blockchain revolution.

We are ready to onboard millions of those developers offering the convenience that only an Operating system used by more than 95% of the world’s machines can offer.

Everstake: Cartesi is truly going to change the crypto adoption curbe . Very impresive.

Do you want to create more games than poker in the future? Do you have any ideas when?

Joe Nance: Yes we currently are accepting applications for games from all developers who would like to have its game implemented using Cartesi tech.

Please feel free to visit our Labs webpage: https://www.cartesi.io/en/labs and apply for one of the grants!

Everstake: Thank you for your answer!

And our last question is: Can the recent partnership with iotex, that already succeeded in launching real world machines, bring a new product development for Cartesi? Which can it be?

Bruno Maia: The partnership with IoTEX has a huge potential to take IoT applications to the next level.

With the Cartesi Blockchain OS, the sophistication of applications that can be developed using the information collected by IoT devices, including Pebble from IoTEX, is almost limitless.

We recently ran an Ideathon where we ended up with very nice ideas. For example, a geofence application to charge boats its right toll on Marinas or a more reliable review system where only people who actively have been around the location could leave its review, or our grand winner idea, elected by the community, a solution called home safety that could diagnose based on some metrics if a person is or not in a dangerous situation, all of course verifiable by Cartesi tech.

We will be handling a hackathon inviting the best five proposals to join the event. Meanwhile, we welcome the community to apply for a grant in Cartesi Labs (https://www.cartesi.io/en/labs) and, if selected, we can support your idea to be implemented.

Thank you very much for participating in this AMA!

We were very pleased to talk to you, Bruno & Joe☺️
