I want to be a piston in the machine that tears down the edifice of a defective financial system. I want to be a brick in the ziggurat of decentralization. I don’t want to get rich quick The amount of talent & time that’s wasted in this circular firing squad is self-sabotage

@MrCampbell @ShutterNetwork Paying L2 beat to list your centralized L2 has gotta be a cuck or shame fetish

Whoever is managing comms at L2BEAT is a psychopath and I love them. > Announces they've listed Gnosis Chain > Drops a 10 post thread eviscerating their security and centralization, calling them a sidechain and saying nobody uses @ShutterNetwork. Truly goated.

@MrCampbell Devcon there’s a larger emphasis on the central venue, more talks, etc. devconnect is more like “let’s all hang out in this city and host events, and I guess there’s a main venue too”

I'm still not sure what the difference is between DevCon and DevConnect.

@joshdavislight @NenaRapsody Asked you some questions ab EPF, check dms

Town hall happening today. Come learn more about the EPF program and how to apply.

@brian_armstrong Imagine 14% of your company getting fired and the CEO is so apathetic they have an LLM write the explanation

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

@PrivacyEthereum Hey I've been working on this exact problem for my thesis. I've done a bunch of writing on this and would love to talk more

We've just designed and implemented Generalized Predicate Proofs for Verifiable Credentials in OpenAC. This lets a credential holder prove complex logical statements over multiple attributes without revealing underlying values. The implementation uses Circom, but the approach can be applied with any zkDSL. Policies can express arbitrary combinations of comparisons and logical expressions, including: • Comparisons to constants or between attributes • Range checks • Set membership and non-membership • Logical compositions E.g. age > 18 AND annual income is between $30,000 and $100,000. The verifier only learns the boolean result, confirming whether the policy is satisfied, nothing more. This design is not tied to OpenAC and can be implemented in any Verifiable Credential system.

@ViviPlasenciaC @NicoSerranoP Hey I’ve been working on this exact problem for my thesis. Would love to talk more!

OpenAC now supports generalized predicates. You can prove arbitrary logical expressions over credentials (AND, OR, comparisons, etc.) without revealing anything else, only whether the full expression is true or false. e.g. age > 18 AND annual income is within a range Feedback very welcome!

@ViviPlasenciaC @NicoSerranoP dm'd you

They’re public on @l2beat !

@donnoh_eth @l2beat MY GOATS

@joddoss for all the L2s that have a security council you can find a link with the list of names on @l2beat

Are security councils public? If I’m opting in to trusting a 3rd party with control of all my funds I should know who the 3rd party is

@tayvano_ @_Enoch If I choose to use an L2 with a security council this is what I’m signing up for. Same as using USDC on L1

@joddoss @_Enoch I'd be the first one to sign a freeze of clearly stolen funds sat directly in the primary theft address. Be careful what you wish for.

@tayvano_ @xzhvyr Ah yes. I recognize all these people

@joddoss @xzhvyr what, its literally public. just bc you dont educate yourself doesn't mean its not public.

@tayvano_ @_Enoch Hi Tay! I’d sleep better at night if I knew you were on some of these security councils, but I still don’t know the other 8 people! I don’t want to put my money in a mysterious dark hole in the wall without knowing who’s on the other side

@_Enoch @joddoss you can sue anybody for anything. you will not win here. law is law children. good luck, but don't trust philosophers to advise you on real world matters.

@_Enoch Good!

@joddoss Arbitrum's is. If you accidentally burn all of your money and they don't revert your transaction, you can sue them. docs.arbitrum.foundation/security-counc…

@xzhvyr ❤️

@joddoss was being sarcastic boss; i agree it should be easily available info

@xzhvyr They weren’t forced to be on the security council. They’re trusted to look after billions of other people’s money. If they want practicality they can simply leave the council

@joddoss oh so now you want our security council to get mugged not very practical of you man
