Most engineers think their CV is about listing experience. It’s not! CV’s real job is to earn you the conversation in under 10 seconds. This is one of the most detailed breakdowns we’ve published on how to write a CV for Web3 technical roles based on 400+ interviews we conducted in 2025. We breakdown: - how recruiters skim CVs after the ATS filter - how to write a professional summary that signals depth immediately - how to turn roles into quantified impact (TVL, % improvements, adoption) - how to present web3 skills so they’re easy to evaluate - how to showcase projects, open-source work, private audits, and hackathon wins properly - how formatting and structure quietly make or break your CV We’ve also included a free CV template (no login, no gating). If you’re applying for technical roles in Web3 (or knows someone who is) this should save weeks of iteration. Credit to @itsme_madara for doing the heavy interview lifting, spotting the patterns, and pulling this guide together.

Started my Zk journey around February with the help of @kirkthebaird 🍃& @RareSkills_io ⭐️ Decided to implement a little of what we learnt in a few weeks. I managed to find 6 ZK related bugs in the Base Azul Comp @immunefi Happy to see it paid off even while I’m still learning.

“this cycle feels different from the last ones” heard that come up in 3 separate conversations today. If you were impacted by the @coinbase layoffs, you might wanna check out @RareTalent_xyz, we’ve got a few open roles we’re looking to fill.
Brian Armstrong@brian_armstrong

This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

Getting started with ZK isn’t easy. One reason is that there are many possible paths. I personally think the best approach is to learn one proof system end-to-end, so you can see how the ideas in ZK fit together. It could be Groth16, PLONK, or STARKs. I like Groth16 and Pinocchio. To understand them, you need to know modular arithmetic, the basics of groups, fields, and elliptic curves. You don’t need to know everything about these topics - you don’t need to understand what a Twisted Edwards curve is - but you do need to understand homomorphic encryption and how we can hide values in points on a curve. You’ll also need to learn a bit about circuits, instances, and witnesses. You’ll learn R1CS, which is an important arithmetization, and then later compare it with Plonkish systems to see how different they are. You’ll learn how to encode constraints as polynomials and how it’s possible to use simple polynomial properties to prove multiple constraints by checking just a single constraint at a random point. This idea, often called the zero-th check, or quotienting, is used in every proof system based on univariate polynomials. It’s how we achieve succinctness. However, the prover needs to commit to a polynomial or evaluate a polynomial without knowing the evaluation point. This leads the student to learn about toxic waste and trusted setups, which are fundamental concepts in SNARKs. Finally, the protocol itself. Pinocchio and Groth16 address security by introducing toxic waste tied to the circuit - essentially placing the circuit inside the trusted setup. It’s elegant and not too hard to understand, but it’s also not ideal: if the circuit is part of the trusted setup, then every time the circuit changes, a new trusted setup is required. This naturally leads to the idea, after Groth16, of looking for protocols with at least a universal trusted setup. The student can then move on to systems like Aurora or Marlin. Then take a detour to another arithmetization and move to PLONK with its Plonkish arithmetization. Even though QAP-based protocols like Pinocchio and Groth16 are no longer the most "popular" (I don't know the correct word here) proof systems, they are still an excellent starting point for truly learning ZK, not just through analogies. Two resources that teach Groth16 from scratch, for example, are the @RareSkills_io ZK Book and the Moonmath Manual for SNARKs. Lecture 9 of the 2023 Zero Knowledge Proofs MOOC also covers this topic.

I built RareCode.ai to address the core difficulty of learning Rust: 1) Watching videos and reading tutorials does not work 2) Practicing is frustrating because there are so many compiler issues that can hit you So I designed a 740-problem Rust sequence that 1) carefully limits the kinds of errors you will be exposed to and 2) warns you in advance of how to avoid errors you aren't yet prepared to handle 3) introduces new concepts slowly while reviewing old concepts The platform is so effective that one person even used it to learn Rust as their first programming language. So, you should have no trouble at all. x.com/Yoann_Alves_/s…

I think people heavily discount how impactful good education is. Newton was a genius for discovering calculus. Now every mediocre STEM student knows it. It's kind of sad the amount of hours society -- especially engineers -- waste trying to understand something that they could get if someone just created a better mental model for it and clearly mapped the prerequisites. You would think AI could just solve this, but in my aggressive testing, that has only partially been the case. AI generally does a poor job of mapping prerequisites and finding connections between ideas that it doesn't already know, unless given a strong hint. It has a really strong bias to repeat what it has read in textbooks, which tend to do a bad job of presenting simplified mental models and mapping prerequisites.
Soubhik Deb@soubhik_deb

one conclusion that can be drawn here is a person from 1930s could have easily grasp an understanding of modern technology of SWE with almost similar educational program. one can probably do an extensive research on understanding how humans (via synthetic representation through vintage LLMs) from different past eras could grasp current tech.

RareSkills has a Rust learning platform for developers coming from other languages. There are over 700 problems tailored to take you from the basics (not exactly beginner-level, you should already know how to code in some language) to advanced topics. You can read books and watch videos, but you really learn by coding, and RareCode helps a lot with that.
