In the last week, the NFT lending protocol BendDAO has been undergoing a liquidity crisis. A large amount of ETH deposits have been withdrawn over the past week. As of 4 p.m. on August 23, the protocol’s lending utilization rate reached 99.26%, with only 90.03 ETH of liquidity available. This means that the vast majority of ETH depositors will be unable to immediately retrieve their assets from the protocol. The worst appears to be over due to the urgent adoption of a new proposal. We analyze...

We talked about an overview of crypto wallets earlier, and the last lecture was about the use of imtoken wallets. The main content of this lesson is Metamask. There are two versions of metamask, one is the wallet plug-in in Chrome, which is also the most commonly used, and the other is the mobile app. Here we mainly talk about the most commonly used Chrome browser plug-in version. 1.

Starting from May, with some three-digit and brand name ENS sold at high prices, this project, which was launched in 2017, came into the limelight. At the same time, a large number of other DID projects have been launched to compete in the DID space. A good DID project is .bit, which was previously called DAS. This article explains the principle of .bit, and its advantages, and compares it with ENS to evaluate the potential and value of this project.1. What is DID?DID (Decentralized Identifie...
