The tx costs of all ZK-rollups will be determined by the cost of data availability. This is why optimistic rollups can cost tens of cents per transaction despite neglible computation overhead. 2/ l2fees.info

This is a humbling moment for Ethereum and rollups. We're taking too many shortcuts and not moving fast enough towards our vision.
@dYdX has no decentralized L2 alternative as of today. This is a justified decision, but not for long. L1 model is unsustainable.
Some thoughts on what this means for @zksync and the ecosystem in general: 🧵
2/ ZK rollups are the end-game of ETH scaling. Everyone in the advanced tech circles already knew it. Polygon now brought this fact to the attention of the broader crypto public.

1/ Really well-written arguments by @kaiynne! A perfect starting point for the conversation about L2 scaling.
The crucial question not addressed in this post: what about negative network effects of OR (aka you can't securely hold >$50M in a single OR instance)?
2/ As @VitalikButerin pointed out in his ETH Online talk, optimistic rollups expose stong anti-network effects: the more volume a single OR has, the less validators can/will run the full node, i.e. the less secure it is to rely 1-of-N honest assumption.
But it doesn't end here.

Interesting reminder how security is holistic: it includes cryptography, protocols, clients, user flows, habits, etc. A system is only as secure as its weakest link.
A thread on key management in @zksync, dangers of pwd-protected wallets, and what's wrong with Ledger 👇
Passwords are notoriously unsecure because most ppl don't care to diversify them across different services – it's just too hard. Hackers posses over half a billion of compromised pwds linked to user identities: haveibeenpwned.com/Passwords
