카이로 프로그래밍 언어: 스타크넷의 인사이트와 도전 과제

### 카이로와 스타크넷 탐험하기: 개발자의 여정
* 🌐 카이로는 이더리움의 레이어 2 ZK 롤업인 스타크넷을 위한 프로그래밍 언어로, **저를 포함한 많은 개발자들이 혁신적인 탈중앙 금융 프로젝트를 위해 솔리디티에서 카이로로 전환**하고 싶어 했습니다.
* 💻 제 여정은 회사가 스타크넷에서 DeFi 프로토콜을 구축하는 방향으로 방향을 전환하면서 시작되었고, 우리 팀은 **지난 3~5개월 동안 카이로에서 코딩**을 배우고 익혔습니다.
* 📚 언어가 제한된 리소스와 상용구 코드가 있는 알파 버전이라는 어려움에도 불구하고 저는 **Starknet 생태계와 여기에 기여하는 똑똑한 인재들**에 대해 여전히 낙관적으로 생각합니다.

Cairo and Starknet, which is, if people don't know, Starknet is a layer 2 ZK Roll-Ups on Ethereum. Cairo is their programming language, and I'm interested in how did you get started with Cairo, and how is it different from Ethereum, and what did you do there. Yeah, so basically, with my normal job that I'm a blockchain developer, I started with Solidity, but then the company business pivoted off to we wanted to do something innovative, something good from a business standpoint, and the leaders of the company decided that building a DeFi protocol and Starknet is a great move. So then everyone from the team starts learning Cairo, started coding with it, me included, and yeah, basically, I have been coding with Cairo for the past three or four months, or five months maybe. Um, and I have already felt the technology, which is an inside joke with Cairo because there you have this value type that is called Fels, are everywhere, right? So everything is spelled like strings, ins, everything is

like addresses felt exactly everything is felt, and I can say I'm very bullish on the Starknet ecosystem. I think, uh, I like to follow the smart people, and I know there are lots and lots of smart people there in this ecosystem working and building, uh, now OpenZeppelin or building their, uh, the same library with good best practices contracts like they have for solution for Ethereum, and some other organizations are starting to work there and to build on Starknet. This is great. Anything the product of, uh, that I was building will do pretty good. Uh, with that said, I would say I'm much more bullish on the Ethereum and the Solidity space. I mean, I'm just more attracted to it. It fits my personality better probably, uh, even though Solidity, because one of the problems I, you can say, related to Cairo is that it's still an alpha version. I mean, it's not even a beta version. There is a lot of boilerplate in the code. There's a lot of ceremony you

have to write some code that you shouldn't have to write. Uh, it's like copy-paste it everywhere. Um, also, you do not have four loops, for example. The language does not work correctly with them. You need to do recursion instead. Um, there are some small, small stuff like this. And of course, you do not have much already written code like libraries. Open Zeppelin are just starting to build it out. But with Solidity, even though there, you still, you do not, it's the version still starts with a zero. We do not have even version one in Solidity. I think the space is much, much more mature, of course, because it's like six or seven years old now. So, I like it a lot. It fits me better as a personality. But I'm very bullish on StarkNet and on Cairo. And I think for some people, it will be one of the best bets. Yeah, interesting. So, yeah, it's very interesting what you're saying that both of them are very early and immature. And Cardio even is even

newer so you have less resources left, less places to learn from, and the language is, like, to be honest, pretty awful. But now they are working on Cairo 1.0, right? That's going to be released soon, which is going to be much more, much better with for loops and other types. It's interesting. So, do you have any tips for people who want to get started with Cairo? How did you learn Cairo? What kind of resources did you use, especially where it's very hard to find them for Cairo time? Yeah, that's one of the bad things; there is not so much information with it because with Solidity, when you get some compilation error or whatever, you can just Google it. Solidity got up to this point; now the ecosystem grew enough, but with Cairo, you cannot do this. If you Google it, you get nothing, so it's kind of shitty. But there are great docs on the StarkNet website. You can find great docs both for the StarkNet ecosystem and for Cairo, and you can also

one advice I can give you is to go through Open Zeppelin's Cairo contracts repository. There, you can find the best of the best practices. You can see how to protect yourself from underflows, overflows, to validate the number of values, if they are correct number values or whatever. This is one of the best places to learn right now, I'd say. I think the best way to learn a language is by reading a lot of code and, of course, practicing, trying to write. So, yeah, you can pick up some small exercises, try to implement a staking protocol or anything that is simple. That's a good approach, yeah. So, it's very interesting what you're saying because there are not many resources, and you cannot just Google the error and find it right away. There are no resources about security pitfalls and security problems, so it's even more not mature. But lucky us, there are not that many protocols on mainnet, even if there is any. I don't know how much money there is there, but it's very early.

so there is not much money in the stake right now, but it's very important that it will be built in a secure way, and there will be more and more resources. And I didn't tell it to you, but actually, I'm working with another business partner on gingersack. We are a security auditing, and we here especially focus on Cairo. And he started posting articles about Cairo. For example, the recent article was about the problems with integer overflows and fails and integers. Well, you have like the first 128 bytes and then the second 128 bytes, and how you can like manipulate it. So we will try also to contribute to the Cairo and Starknet Community because we like you. Likewise, we also believe that it's going to be huge, maybe not like Solidity and EVM, but it's a very important way to scale it up. And yeah, definitely. So it's very interesting evolvement to the scalability of blockchain. Sounds good, sounds great. The community really needs people like this. The community needs people who post blogs.

posts share knowledge on Twitter. Everywhere is great.

카이로 및 스타크넷으로 전환하기

블록체인 개발자인 발표자는 회사가 스타크넷에서 탈중앙화 금융 프로토콜을 구축하는 방향으로 전환하면서 솔리디티에서 카이로로 전환했습니다.

지난 3~5개월 동안 카이로를 사용해 코딩을 해왔으며, 카이로 언어에서 "펠트" 유형의 독특한 사용을 높이 평가했습니다.

이들은 스타크넷 생태계와 스마트한 개발자들을 긍정적으로 평가하면서도, 카이로의 알파 버전과 코딩 문제를 잠재적인 단점으로 꼽으며 이더리움과 솔리디티에 더 매력을 느끼고 있습니다.

스타크넷의 프로그래밍 언어인 카이로는 라이브러리가 부족하고 루프 대신 재귀를 사용해야 하는 등의 문제점을 안고 있습니다.

이 언어는 아직 초기 단계에 있으며, 곧 1.

0 버전이 출시될 예정으로 개선이 이루어질 것입니다.

카이로를 배우기 위한 리소스는 부족하지만, StarkNet 웹사이트에서는 생태계와 언어에 대한 포괄적인 문서를 제공합니다.

카이로 계약 및 보안 모범 사례 배우기

오픈 제플린의 카이로 컨트랙트 저장소는 언더플로우 및 오버플로우 방지 등 코딩을 위한 유용한 모범 사례를 제공합니다.

코드 읽기와 스테이킹 프로토콜 구현과 같은 작은 연습을 통해 언어를 배우는 것을 추천합니다.

강연자는 또한 보안 감사 업체인 Gingersack에 참여하여 카이로에 중점을 두고 일반적인 보안 문제에 대한 글을 통해 커뮤니티에 기여하고 있습니다.
