Eth2 is ready

officially launchedofficially launched. This new testnet is running the full mainnet configuration for phase 0 of eth2. There has been a lot of discussion about the hardware required to run eth2 beacon nodes and validators, so I wanted to offer some personal insight here.

Beacon nodes are heavy nodes (like the current eth1 node software), and validators are lightweight. To stake in eth2, you can spin up your own Beacon node and point validators at it, or use a third-party node. In both cases, you only need one Beacon node, but you will need to use a new validator for every 32 ETH you plan to lock (remember, validators are lightweight). This means you can run the validator on hardware like a Raspberry Pi or other mini PC, but if you want to run your own Beacon node, you'll need a higher performance system. Hope this explanation provides some clarity!

This week, ethhubAdded a new guide ,A simple explanation is given for ERC20 tokens on Ethereum.

A class-action lawsuit seeking more than $28 million from the Maker Foundation and several associated companies is scheduled to be filed in U.S. federal court, according to documents obtained by The Block.

In the draft complaint, the Maker Foundation — a nonprofit that developed the MakerDAO decentralized finance (DeFi) protocol — is accused of misrepresenting the protocol’s risk to investors and failing to protect investor interests.

Gnosis protocol officially launched

Gnosis officially released their protocol this week, the culmination of two years of research and development. The Gnosis Protocol is a completely permissionless DEX (Decentralized Exchange Protocol) that uses a new mechanism called ring trading that maximizes liquidity. Ring trading in particular improves liquidity for illiquid or "long tail" tokens such as prediction market outcome tokens by facilitating transactions that are not normally possible with traditional trading protocols.
