@MsMelChen The solution is to rally around open source.

That's the only way to compete with a superpower technology network effect if you are not a superpower yourself. And it's the only way to bring the rest of the world along on the same team as you.

Open source.

@ldwgwttgnstn our team member Pablo told me about a VRF oracle that you built and wanted some feedback on. I tried to DM you but your DMs aren't open, wanna message me?

@melooox3 @switchboardxyz 🫡🙏🙏

[Switchboard ⚡️ @switchboardxyz]

Fundraising has changed.

Before: funding for ideas

Now: funding for built products

Hear why @refihub is the first project to raise on @craftsdev

[Jack @ Switchboard @jackswitchboard]

@hail_d_lord @switchboardxyz Good luck! Really glad we could help 😃

I’d like to formally apologize for my behavior at E11EVEN last night.

The videos are real. The allegations are true.

While permissionlessness is important onchain, it has no place onstage.

Mandatory attestation before entering any 'trusted execution environment' from now on.

The last few weeks have been brutal for DeFi.

Nearly $600 million lost in just two high profile exploits in April alone. Both beyond the smart contract layer.

Crypto's biggest failures are no longer just smart contract bugs. We need a broader security model.

Solana with BAM is quite literally unstoppable.

[Switchboard ⚡️ @switchboardxyz]

Putting price data on-chain? Easy
Doing it in real-time? Easy
Keeping it private? Easy
Making it permissionless? Easy

But in the age of AI, the on-chain data landscape is changing. And the hard part is what comes next.

And what's that? Link below:

The digital attack surface has become exponentially more dangerous. I see a world where all infra is TEE verified to at the very least need physical attack vector as well to do such an exploit.

@Savage_9988 @savageprotocol @solana @switchboardxyz Thanks for the report! I'll take a look at this.

[Switchboard ⚡️ @switchboardxyz]

Today’s exploit at Drift is a difficult moment for Solana and DeFi as a whole.

This was a highly sophisticated attack. Reports indicate the root cause appears to be compromised admin keys used for malicious protocol changes.

Switchboard oracles remain fully operational.

Our thoughts are with the Drift team and all users impacted. Switchboard contributors are working with the relevant parties to help support Drift and the broader Solana ecosystem throughout this difficult time.

Switchboard Agent Skill

We just made it way easier for agents to access on-chain data, put data on-chain, design their own Switchboard feeds, and build using verifiable randomness.

In these five years, the Ethereum Foundation is entering a period of mild austerity, in order to be able to simultaneously meet two goals:

1. Deliver on an aggressive roadmap that ensures Ethereum's status as a performant and scalable world computer that does not compromise on robustness, sustainability and decentralization.
2. Ensures the Ethereum Foundation's own ability to sustain into the long term, and protect Ethereum's core mission and goals, including both the core blockchain layer as well as users' ability to access and use the chain with self-sovereignty, security and privacy.

To this end, my own share of the austerity is that I am personally taking on responsibilities that might in another time have been "special projects" of the EF. Specifically, we are seeking the existence of an open-source, secure and verifiable full stack of software and hardware that can protect both our personal lives and our public environments ( see https://t.co/GzgBS9sh87 ). This includes applications such as finance, communication and governance, blockchains, operating systems, secure hardware, biotech (including both personal and public health), and more. If you have seen the Vensa announcement (seeking to make open silicon a commercially viable reality at least for security-critical applications), the https://t.co/cuyU9Chs1y including recent versions with built in ZK + FHE + differential-privacy features, the air quality work, my donations to encrypted messaging apps, my own enthusiasm and use for privacy-preserving, walkaway-test-friendly and local-first software (including operating systems), then you know the general spirit of what I am planning to support.

For this reason I have just withdrawn 16,384 ETH, which will be deployed toward these goals over the next few years. I am also exploring secure decentralized staking options that will allow even more capital from staking rewards to be put toward these goals in the long term.

Ethereum itself is an indispensable part of the "full-stack openness and verifiability" vision. The Ethereum Foundation will continue with a steadfast focus on developing Ethereum, with that goal in mind. "Ethereum everywhere" is nice, but the primary priority is "Ethereum for people who need it". Not corposlop, but self-sovereignty, and the baseline infrastructure that enables cooperation without domination.

In a world where many people's default mindset is that we need to race to become a big strong bully, because otherwise the existing big strong bullies will eat you first, this is the needed alternative. It will involve much more than technology to succeed, but the technical layer is something which is in our control to make happen. The tools to ensure your, and your community's, autonomy and safety, as a basic right that belongs to everyone. Open not in a bullshit "open means everyone has the right to buy it from us and use our API for $200/month" way, but actually open, and secure and verifiable so that you know that your technology is working for you.

2026 is the year we take back lost ground in computing self-sovereignty.

But this applies far beyond the blockchain world.

In 2025, I made two major changes to the software I use:

* Switched almost fully to https://t.co/ZIKj4U5XFM (open source encrypted decentralized docs)
* Switched decisively to Signal as primary messenger (away from Telegram). Also installed Simplex and Session.

This year changes I've made are:

* Google Maps -> OpenStreetMap https://t.co/Xm0pad5nh9, OrganicMaps https://t.co/yvbwXqEPwo is the best mobile app I've seen for it. Not just open source but also privacy-preserving because local, which is important because it's good to reduce the number of apps/places/people who know anything about your physical location
* Gmail -> Protonmail (though ultimately, the best thing is to use proper encrypted messengers outright)
* Prioritizing decentralized social media (see my previous post)

Also continuing to explore local LLM setups. This is one area that still needs a lot of work in "the last mile": lots of amazing local models, including CPU and even phone-friendly ones, exist, but they're not well-integrated, eg. there isn't a good "google translate equivalent" UI that plugs into local LLMs, transcription / audio input, search over personal docs, comfyui is great but we need photoshop-style UX (I'm sure for each of those items people will link me to various github repos in the replies, but *the whole problem* is that it's "various github repos" and not one-stop-shop). Also I don't want to keep ollama always running because that makes my laptop consume 35 W. So still a way to go, but it's made huge progress - a year ago even most of the local models did not yet exist!

Ideally we push as far as we can with local LLMs, using specialized fine-tuned models to make up for small param count where possible, and then for the heavy-usage stuff we can stack (i) per-query zkp payment, (ii) TEEs, (iii) local query filtering (eg. have a small model automatically remove sensitive details from docs before you push them up to big models), basically combine all the imperfect things to do a best-effort, though ultimately ideally we figure out ultra-efficient FHE.

Sending all your data to third party centralized services is unnecessary. We have the tools to do much less of that. We should continue to build and improve, and much more actively use them.

(btw I really think @SimpleXChat should lowercase the X in their name. An N-dimensional triangle is a much cooler thing to be named after than "simple twitter")

@maus_cap @switchboardxyz Thank you for the report, I'm fixing it now!
