Orbit just got a HUGE update πŸ‘€

1. New self-serve option for Arbitrum L2s on Ethereum. No need to ask the DAO.

2. In the spirit of one united Ethereum, there’s a new self-serve option for building L3s atop non-Arbitrum L2s.

3. L3s on Arbitrum One/Nova remain permissionless.

Seeing a lot of misinfo about parallel EVMs. πŸ™…πŸ»β€β™€οΈ

Here's a thread on why they're overhyped, and why EVM+ approaches like Stylus yield lower fees. 🧡

TIL that Apple iMessage uses our Key Transparency work to ensure user security and privacy: E2E encryption on by default with users confident in others' identities.

Unexpected academic impact can be amazing. CONIKS published USENIX Association Security 2015.

A good example of widespread consensus being absolutely correct. Arbitrum, an OR, already had fully functional fraud proofs in 2019, was on the market will before any ZKRs, and now has the largest market share. And yes ZKRs are slow and super complex to build.

I’ve raised the alarm bells about the dangers of L2s being marketed as such without fraud proofs or any meaningful L1 derived security for a very long time.

The response I generally got was β€œthey’re good people. We can trust them to eventually build fraud proofs and not rug in…

Correction: Arbitrum never 'rolls back' or 'rewrites history'. Other optimistic rollups do roll back if fraud is detected, but that's a flaw in their design, not an inherent property of optimistic rollups.

This keeps coming up in panels/classrooms/conversation - people mischaracterize FBI v Apple case. FBI did *not* ask Apple to unlock SanBernardino phone. They wanted Apple to create a tool that would undermine iPhone security so they could unlock ANY iPhone wired.com/2016/02/apples…

Out of all the terrible problems there are in the world today, the problem of small numbers of American university students with stupid or even evil opinions seems to me the least important and least interesting. But clearly, I am in a minority.
