The development direction and opportunities after the Ethereum Shanghai upgrade
The Shanghai upgrade is an important milestone in the development of Ethereum, set to be completed in April with the opening of the beacon chain staking ETH withdrawal feature. This upgrade is a hard fork of the execution layer, expected to implement 9 EIPs. As of mid-March, approximately 17.5 million ETH has been staked, accounting for over 15% of the total supply. On average, each validator has accumulated more than 2 ETH in staking rewards, and after the upgrade, over 1 million ETH will flow into the market.
The impact of Shanghai's upgrade on the Ethereum ecosystem is far-reaching. This article will focus on the withdrawal mechanism and related risks of Ethereum and the LSD protocol after the upgrade, as well as the potential effects on ETH prices and the prices of LSD-related tokens.

Withdrawals are implemented jointly by the execution layer and the consensus layer, including "partial withdrawal" and "full withdrawal". Partial withdrawal only extracts profits, while full withdrawal exits verification.

d/acc: A Review and Outlook One Year Later
Last year, I wrote an article about technological optimism, outlining my overall enthusiasm for technology and the tremendous benefits it brings. At the same time, I expressed a cautious attitude towards certain issues, mainly focusing on superintelligent artificial intelligence and its potential risks.

We need to accelerate technological development, but selectively focus on technologies that can enhance defensive capabilities rather than destructive capabilities, and commit to promoting power decentralization to avoid concentration of power in the hands of a few elites.
Over the past year, these concepts and ideas have undergone significant development and maturation. I shared these thoughts on the "80,000 Hours" platform and received numerous responses, most of which were positive, although there were also some critical voices.
