Trying to get better at posting what I build :)

Tried Composer 2.5 this weekend and mocked up a ChatGPT-inspired message map rail for long Cursor chats.

A quiet way to see where you are and jump between turns.

Coinbase is to current finance/banking what Charles Schwab was to finance/trading in the late 70's and 80's.

Schwab radically disrupted Wall Street then. Coinbase is radically disrupting Wall Street now.

Schwab ultimately destroyed commissions and fees on transactions. Coinbase is destroying market hours, access, tech, and margins/interest.

Extraordinary to watch. Wall Street and markets are significantly evolving in real time and Coinbase is leading/pushing the huge changes.

Today we've published the first position paper from the Coinbase Independent Advisory Board on Quantum Computing and Blockchain, a group of leading researchers from Stanford, UT Austin, the Ethereum Foundation, and beyond.

The short version: your crypto is safe today. But a quantum computer capable of threatening blockchain cryptography will eventually be built, and the industry needs to start preparing now, not when it's urgent.
The paper covers what's actually at risk, what isn't, where major blockchains stand on migration plans, and concrete recommendations for chains, custodians, and institutions.

We stood up this board because we believe security decisions of this magnitude should be driven by the best available science. This is our first report, but will have more updates to share as we go.

It's been a crazy five years since Coinbase went public. So proud of our team, and the entire industry, for everything we've achieved since 2021.

[Philip Martin @SecurityGuyPhil]

The latest quantum papers from Google and Caltech are an important signal for the industry. Timelines are still debated, but the time to act is now.

The good news: post-quantum cryptography exists. This is a solvable problem, and many chains already have roadmaps. Bitcoin needs to catch up though.

The bad news: post-quantum cryptography is relatively new and it would be fairly easy to create new security risks if implementation is rushed. The industry needs to align on what happens to wallets that fail to migrate before a CRQC appears.

At Coinbase, we’ve been working on this for a while, auditing and upgrading our internal infrastructure, researching post-quantum cryptography and establishing a Quantum Advisory Council. It’s clear Bitcoin needs to make some fast progress here, so Coinbase is taking the role of rallying the troops and getting the right people in the room - Bitcoin core devs and the broader community - so they can start tackling this.

But no one developer or company can do this alone. Real progress will require coordinated action across the ecosystem.

If you’re working on post-quantum approaches for Bitcoin, we want to support you, and connect you with others that are working on it too. Please DM me directly and I’ll get you added to the working group.

Bitcoin can and will upgrade, but it will take the entire community working together.

@nikitabier @ChrisMack_ @WallStreetApes You know that a sauna into cold plunge is a good thing, right….right?

@nikitabier @WallStreetApes This is terrible.

I'm looking for a design director to lead a team doing some really creative work at the intersection of brand and product at @coinbase. Hit me up with your portfolio if you're interested in learning more.

JUST IN: 🇫🇷 Coinbase CEO Brian Armstrong calls out French Central Bank Governor's misunderstanding of Bitcoin.

"Bitcoin is a decentralized protocol...Bitcoin is more independent."

[Brian Armstrong @brian_armstrong]

After reviewing the Senate Banking draft text over the last 48hrs, Coinbase unfortunately can’t support the bill as written.

There are too many issues, including:

- A defacto ban on tokenized equities
- DeFi prohibitions, giving the government unlimited access to your financial records and removing your right to privacy
- Erosion of the CFTC’s authority, stifling innovation and making it subservient to the SEC
- Draft amendments that would kill rewards on stablecoins, allowing banks to ban their competition

We appreciate all the hard work by members of the Senate to reach a bi-partisan outcome, but this version would be materially worse than the current status quo. We’d rather have no bill than a bad bill. Hopefully we can all get to a better draft.

We'll keep fighting for all Americans and for economic freedom. Crypto needs to be treated on a level playing field with the rest of financial services so we can build this industry in a safe and trusted way in America.

@GregCapullo In hindsight it’s pretty clear, it’s all in the details. Todd adds details on top (action, exaggeration), your details are in the core (structure, composition).

@CoinbaseDuck Ah, just based on timing then?

Five freedoms in crypto:

1) Freedom to control your own money
2) Freedom to move your own money
3) Freedom to invest your own money
4) Freedom to preserve the value of your own money
5) Freedom to raise money

[Dangerdom 🛡️ @Dangerdom]

@jaysonhobby Agree, if the primary use case is investing. Think coins can power a lot of other use cases under the hood where the user doesn’t even know a “coin” exists. We should just focus more on the use cases instead of creating for the sake of existence.

[Aderinsola Akintilo @The_Aderinsola]

Watching Figma Schema.

Lots of great news, but easiest share is Coinbase's design system.

Thanks @coinbase & @siddharthkul!
