An example of dishonest journalism by

@MuyaoShen
. The word "sanctions" was never even mentioned during the interview. When I pointed that out after the article was published, they started to ignore my messages and didn't change anything.
One of the founders of Tornado Cash, among the most popular services to hide crypto transactions, said it doesn’t need to comply with sanctions

Maybe more useful categorization

- Voyager: Regulated
- Genesis: Regulated
- Silvergate: Regulated
- SVB: Regulated
- USDC: Regulated
- 3ac: Regulated
- Celsius: Regulated
- Luna: Unregulated

Sad to see that L2s compete on yield, TVL, and token prices rather than who implements fraud proofs and removes admin keys first. Without fraud proofs it's called a sidechain secured my a multisig, not an L2.
Why does
@Blast_L2
get more TVL in 24H than technically superior zkEVMs can in months?
It's simple: without the embedded staking yield, bridging to your L2 is an opportunity cost
Staking the ETH locked in bridging contracts is something I've been trying to push for some time.…

Dapps can have an immutable UI snapshots using ENS+IPFS by creating a subdomain and burning the access to it. Like v3.uniswap.eth for the main updateable UI and 2022-04.v3.uniswap.eth for an immutable snapshot. This should be easy to do using an upcoming namewrapper contract.

It's basically a GPT feedback loop with access to external tools. AI plans how to solve the problem, executes the next step using external tools, and then thinks about the next steps to take based on new data.

Friendly reminder that Optimism is not an L2 yet. In L2 by definition the admins *don't have the ability* to freeze/confiscate funds (= L1 security). Currently in Optimism they can but they won't, it's a sidechain until the admin key is removed.
In principle, a network upgrade could be carried out to halt the movement of those OP tokens which have not already been transferred or sold.
We will not take this step at this time due to the precedent it would set. Optimism is a permissionless network and behaved as intended.

Can inflation be considered a form of wealth tax? The more money you have, the more you lose to the inflation every day. The workers with salary don't care much about it while rich people have to do all sorts of stuff to keep earning more than they lose.

DeFi grew too dependent on traditional finance. For example, DAI v1 was pretty resilient but then switched to USDC collateral, now if USDC fails -> DAI fails as well. Similar for Compound v2 vs v3.

Funny how it's "you don't need privacy if you have nothing to hide" for ordinary people, but "encrypt, delete after 10 days, and no screenshots" when the FBI colludes with social networks to do censorship.

By reducing engagement on sites like StackOverflow and Quora ChatGPT reduces the amount of data available for future training. Fewer data -> lower quality answers -> more people go back to StackOverflow. Interesting how things will balance out in the end.
Wonder what the impact of ChatGPT is on StackOverflow SO.
Six months ago, I didn't go a day without visiting SO. Now I find ChatGPT almost always answers my coding questions accurately (and much faster and with more directly applicable code examples).

The people were given voting tokens, significantly more than VCs have. Even airdrop users, not counting LPs, were given way more tokens than a16z has, which totals around 4.2% across their wallets.
