"We really need multi-currency stablecoins across the board. The people that are saying it's just all gonna be dollars, I think they're wrong. I think we need stablecoins basically for every currency."
@SimkinStepan, CEO of Squads / @altitude used Stabledash Live to make an open call to stablecoin builders:
"If you're doing anything cross-border, you're dealing with different currencies. You don't want to just get your FX rate just in time. You want to do proper treasury management, hedge yourself from any FX risk, hold different currencies on your balance sheet. It's completely normal."
"A lot of teams are going after different local currency stablecoins, but they're all very early and there's zero interoperability."
"We'd love to talk to anybody who's trying to figure out how to do this efficiently."

Over the years @trailofbits has become a household name in cybersecurity. In this conversation with Trail of Bits' founder @dguido, we dive into the complete journey, from how they got started, to nearly going out of business during the government shutdown, to becoming a well respected pioneer in the industry.
We also touch on a variety of other topics, from Lazarus Group's activities to the impact of AI on cyber from both an offensive and defensive perspective.

Formal verification is indeed the way.
A few years ago I reached out to @NotDeGhost asking him if he wanted to do the first formal verification for a Solana program. Luckily he said yes and got it done in 4 months. Since then all Squads programs have gone through that process multiple times.
Fast forward to today, we now also have Certora and many of the core ecosystem programs formally verified.
The biggest issue with FV is that it takes time and is very expensive. While the AI security apocalypse is stressful, it is also obvious that LLMs will help us drastically compress the time and cost it takes to prove the mathematical integrity of onchain codebases. Maybe that will be the silver lining of it all.

There's a lot of confusion about the recently patched Zcash bug. Here's how to actually understand it.
If the bug had been exploited before the patch (very unlikely it was), it would have looked like the shielded pool getting drained. Whoever minted the counterfeit shielded ZEC would want to sell fast, before anyone else found the same bug. And remember, the market for ZEC is almost entirely transparent ZEC, not shielded. You can't dump freshly minted shielded ZEC on Binance or Coinbase without unshielding it first.
The losers in that scenario are shielded holders who sit still. The transparent portion of Zcash is fully visible, so it's trivial to enforce that transparent ZEC never exceeds max supply. If you try to unshield more than the cap, you'll get stopped at the door.
So if you hold transparent ZEC (anyone trading, on an exchange, or doing price discovery on ZEC) there's no marginal effect on you. The loss falls entirely on shielded holders.
The team's next step is a new turnstile and a fresh shielded pool in the coming upgrade, which will confirm the shielded pool was not inflated. Think of it as taking headcount at the end of the field trip--that will make sure no extra kids snuck onto the bus.
But while AI found this bug, AI will also deliver the fix for the whole category: formal verification. I'm very bullish on this as the path to harden all software across the industry. Formally verified cryptography can't have implementation bugs by construction.
Right now AI is surfacing vulnerabilities across all our software--browsers, OSes, and blockchains are no exception. We're in the awkward adolescence where every wart is getting magnified and put on full display. But formally verified software is the only path forward for mission-critical software, and Zcash has put it front and center on their roadmap to deliver.
Privacy is too important not to.
(Dragonfly holds $ZEC and continues to. I'm personally an investor in ZODL.)
