@cubistdev co-founder and UCSD professor Deian Stefan @deiandelmars is at #TrustX2023 discussing design principles + pitfalls of building secure hardware-based systems. Here's the short version: 🔓 Not all secure hardware is actually secure SGX is broken and makes your system less secure than not using enclaves at all 🪄 Secure hardware is an abstraction, not magic You can’t just shove large systems into a Nitro Enclave and hope to get security 🛡️ We can use hardware correctly Minimize the (amount, complexity, and privilege of) code running in the enclave and use a narrow well-typed interface across the trust boundary
The underlying goal when building secure systems? Minimize the trusted computing base (TCB) - the code we need to get right

Yesterday at @eigencloud's Restaking Summit, @cubistdev CEO @kwantam demo'd our anti-slasher. He showed multiple validator clients running simultaneously with the same keys, which can easily happen by accident (for example during maintenance) and is a major cause of slashing. Because of the anti-slasher, the validators were completely safe. Running validators at scale is hard. If you want to protect large-scale deployments with a tool like Web3Signer, you have to carefully architect complex infrastructure that's easy to get wrong, and any mistake leaves you vulnerable to slashing. Techniques like DVT add yet more complexity—and they only help under the assumption that at least half of the participants have correctly configured slashing protection. Protections that come down to "just don't mess up" aren't good enough when your ETH is literally at stake. A validator that signs with CubeSigner relies on a simple, bulletproof abstraction: a validator key that will never sign a slashable message. The result is that you cannot misconfigure your validator infrastructure in a way that gets you slashed. By the way, we still have two validator clients running simultaneously with the same keys: holesky.beaconcha.in/dashboa…

@cubistdev CEO Riad Wahby just took the Main Stage at the #StakingSummit to talk slashing, front running, exit stampedes, and all things staking security. The question is, “is it possible to build a better key abstraction that makes all these risks go away?”

Today @redactedcartel has upgraded the Pirex ETH testnet deployment to be feature-complete. We've open-sourced the contracts and shared our completed audit by @SpearbitDAO (more audits are underway). Users & devs can now test integrations from the vault to the validator layer.

If honest node operators and Bitcoin holders feel confident they can stake without getting slashed, this is a huge win for the security of Proof-of-Stake chains. Read more how we're working with @babylon_chain to make Bitcoin (re)staking safe by design: cubist.dev/blog/cubist-babyl…
“Babylon unlocks the $600 billion crypto asset stored as Bitcoin today by allowing Bitcoin holders to stake their Bitcoins to secure any proof-of-stake chains and earn yield. The staking is done in a trustless and non-custodial way to provide 100% security to the Bitcoin holders at the protocol level. But we don't just stop here. We are excited to work with Cubist on making Bitcoin staking safe at the system and operational levels, too—in particular, on making it possible for honest node operators and Bitcoin holders to stake without worrying about getting slashed due to bugs, mistakes, or network issues.” —Fisher Yu, Co-Founder and CTO of Babylon

4/ Slashing is key for protocol security—but in practice, honest operators can get slashed because of everything from validator client bugs to infrastructural errors…and protecting (hot) staking keys from slashing-minded attackers is deceptively hard.
