Hold on tight! 🎢

Spice of the weeks 🍿
---------------------

**Worries around worries around liquid staking**

*   The Messari researcher Kunal Goel [shared](https://x.com/kunalgoel/status/1706597073259303323?s=20): “The amount of ETH staked has consistently grown (as I had predicted) and shows no sign of stopping. Along with that, Lido's share too has remained high and is nearing a key threshold of 33%.”
    
*   One [replied](https://x.com/witconomist/status/1706607506523627990?s=20), “Hoping on social agreement holding in a trustless system is not smart. The entire premise of crypto is that it's economically guaranteed.”
    
*   Dankrad [argued](https://x.com/dankrad/status/1707014810565566962?s=20) with the provided counter argument claiming that “No economic incentives will automatically guarantee our values such as immutability or censorship resistance -- the values of the Ethereum community do this. \[…\] If you believe that crypto values are simply individual profit maximization, you have missed the plot and are in the wrong place. \[…\] Yes, we do try to build our systems to be as robust as possible and to get the economic incentives aligned with our values as much as we can. But perfect alignment is ultimately impossible, for the simple reason that centralized systems are more efficient than decentralized ones.”
    
*   The Ethereum community [supported](https://x.com/zengjiajun_eth/status/1707015810097791400?s=20) the Dankrad’s view: “At the end of the day, it’s all about social consensus, or legitimacy.”
    

ZK and rollups research 🧙
--------------------------

*   A [paper](https://www.hertzbleed.com/gpu.zip/GPU-zip.pdf) on why using GPUs for cases where you need privacy (like ZK proof generation) may be a bad idea by Yingchen Wang, Riccardo Paccagnella, Zhao Gang, Willy R.
