"“The RareSkills Circom Bootcamp significantly advanced my ability to transition from theoretical study to practical application in zero-knowledge proofs.”"

I'm Santiago, a systems engineering student who dedicates his free time to researching the security of smart contracts and systems in general. Earlier this year, I dove deep into the theory behind zero-knowledge proofs, with the ZK Book as my primary resource. Wanting to take the next step and put that theory into practice, I didn’t hesitate to join the Circom Bootcamp as soon as it was announced. RareSkills’ strong reputation in the industry and...

"I joined the Circom bootcamp after great experience with RareSkills' Advanced Solidity one, because I want to master ZK"

I joined the Circom bootcamp after great experience with RareSkills' Advanced Solidity one, because I want to master ZK Great mix of live tutoring, reading written materials and watching videos. Homework was challenging as expected and I really appreciate it. That's the best way to master the topic in my opinion. Attending this bootcamp helped me add another valuable skill to my skillset.

"If you’re serious about mastering Rust and learning from and alongside the best, this 3-week program is a great starting point."

I’m a former finance executive transitioning into Web3. I joined the 3 week RareSkills Rust Bootcamp to gain a strong introduction to writing safe smart contracts and understanding security auditing best practices in Rust. Having followed RareSkills’ insightful blog content for some time, I trusted their team to deliver a well-crafted learning plan. With a couple of months of self-taught Rust under my belt, I saw the 3-week bootcamp as the ideal opportunity to deepen...

"The instructor rightly emphasizes the importance of understanding real-world exploits and how to audit. "

Block is a great Solidity instructor. What I appreciated most about his program is that he always checked our understanding of prior materials before moving onto more challenging topics. He rightly emphasizes the importance of understanding real-world exploits and how to audit.

"I would recommend any serious Web3 developer to consider joining RareSkills"

I joined the ZK bootcamp last September 2024, and I was put in Jeff's cohort. I really think that Jeff is a talented instructor. I never had any problems with learning ZK when I joined RareSkills. The math part was explained to me quite well; I can understand it, and I have a better grasp of the math behind ZK. Thanks to Jeff, João, and the rest of his team. I would recommend any serious...

"I think it’s a great introductory course. I’d recommend it to anyone new to Rust who’s looking to take their first steps with the language."

This was a great introductory course to Rust. I would have liked it to be a bit longer to dive deeper into some of the topics, but overall it provided a solid foundation. Daniel was an excellent instructor—always helpful, approachable, and committed to making sure we got the most out of each class. I’d definitely recommend it to anyone starting out with Rust. I really enjoyed the one-on-one sessions. Daniel was incredibly helpful, and I...

"If you're struggling to learn ZK or want to get an upgrade on your career, this a really great start."

I'm Alexandre, what made me join the bootcamp was the RareSkills zk-book, it was a really good content, but hard to understand without some previous knowledge, so having a teacher going step by step would be easier to understand. My learning experience was amazing, i could see all the effort that was put into it, the teacher was really prepared and we could tell that he was really trying to make us all understand everything,...

"I’d definitely recommend it—whether you’re a developer or a security researcher—if you’re looking to build a strong base in Rust."

The Rust Bootcamp provided a strong foundation, both through the instructors and the course structure. I believe having a solid foundation is crucial to tackle and understand the more advanced topics in Rust, and this program really delivered on that. The instructor was very supportive throughout the sessions and always clear and to the point. I especially appreciated how each concept was backed with solid reasoning. I’m still working toward growing my Rust skills through...

"If someone is considering joining this bootcamp i would say to go for it, it worth the price!"

I joined this bootcamp to improve my rust skills in order to be able to do Solana code. Yeah, it was great. I think it makes my expectation. I learned some deep things about rust is that they needed to learn, maybe I would have liked more security examples, but three classes it was really good, really good about the 1 on 1 session. But overall Danielle was really great and we can feel it...

"Shortly after completing the bootcamp, I managed to win the first Rust audit competition I participated in."

As a security researcher with prior experience only in Solidity, this bootcamp was excellent at quickly bringing me up to speed with Rust and all its intricacies. The bootcamp hit the sweet spot between theory and hands on work, with exercises that actually prepared me to find real security issues. Shortly after completing the bootcamp, I managed to win the first Rust audit competition I participated in.

"RareSkills put me on the right path to becoming a blockchain developer."

Before joining the Solidity Bootcamp, I had six years of experience as a developer but limited time for self-learning due to my full-time job. RareSkills provided the structure, depth, and expert guidance I needed to break into blockchain development efficiently. The curriculum was rigorous, the mentorship was top-tier, and the hands-on experience was invaluable. Without this program, I would have spent years trying to piece everything together on my own. If you’re serious about Solidity...

"I would recommend it to someone who wants to rapidly get up and running in Rust and is especially interested in the security and auditing mindset. "

I am a Computer and Data Scientist that joined the Rust bootcamp in the January 2025 cohort. The course’s fast-paced, intensive structure was exactly what I appreciated. Additionally, there was a security and smart-contract focus in the homeworks which exposed me in the auditor mindset and also several blockchains such as Solana, NEAR, Soroban, Starknet and their way of accomplishing things. The one-on-one sessions were probably the biggest ROI of this course, as I learnt...

Studying at RareSkills has been the best ROI in my blockchain/crypto journey When I joined the Advanced Solidity Bootcamp, I had only a superficial knowledge of Solidity and EVM. Being able to speedrun all of the hard stuff, such as CTFs, Assembly, Gas Optimizations, AMMs, and ECDSA, in less than 6 months, while doing it by myself would have taken 2x or 3x that time, was super valuable for me.It's not only the quality of...

" I highly recommend the bootcamp for anyone who wants to get started with zk proofs."

Zero knowledge proofs are hands down the most difficult topic to master in web3. The RareSkills zk bootcamp is a 9 weeks hands-on program that covers everything. Basic Math concepts to implementation details of real-world zk protocols. Thanks to tons of practical exercises, Jeffrey’s easily understandable explanations and his one-on-one support, I developed a fundamental understanding of the topic and was able to implement Groth16 from scratch at the end of the course.
Bernhard MuellerSmart Contract Auditor

"It's like well structured it covers all necessary topics"

Not my first attempt to dig into ZK thing but with RareSkills. It was my first successful attempt. The rest of the things like old materials that they have on YouTube have marks and signs. Of course they didn't provide me more programmers experience, I'd say. So it was more like math related rather than programming related. In RareSkills. It's both sides. You have no math to the programming, which is great, because I am...

"This course has improved my understanding of when and how to use the different approaches that are available for verifying large-scale computations. I highly recommend taking this course."

I joined the zero knowledge course in order to improve my understanding of the mathematics behind groth16, and to practice constraint-based programming for verifying large-scale computations. The learning experience was excellent. When learning groth16, we first focused on fundamental concepts such as encrypted quadratic arithmetic programs and pairing-based cryptography. This made applying the final transformations that yield groth16 highly understandable. This course has improved my understanding of when and how to use the different approaches...
