b. Several developers jointly released the EIP-7002 draft link

On May 11, several developers jointly released the EIP-7002 draft, which aims to allow validators to trigger exits via their execution layer (0x01) withdrawal credentials.

To ensure that the withdrawal credentials (owned by both EOAs and smart contracts) can trustlessly control the destiny of the staked ETH, this specification enables exits triggerable by 0x01 withdrawal credentials.

d. Ethereum main network’s beacon chain experiences half-hour problem link

On May 12, the beacon chain of the Ethereum main network experienced a problem for about half an hour, and the developer said that the cause is still under investigation.

@superphiz: History suggests that a client has experienced a bug and a patch will be required. Based on our current dependence on mev boost, it’s a potential suspect as well.

@terencechain: We have identified areas where state caching could be improved. Given the chain has stabilized, as a staker / node operator, there’s no action required moment.

The Ethereum uffered from a technical issue on Friday that caused the network to hard to finalize blocks for over an hour, the second such outage in the past 24 hours. DYdX says it paused deposits temporarily today due to the lack of Ethereum finality.

Potuz: Yesterday close to 8pm UTC the Ethereum network lost finality for 25 minutes. Several valid, but untimely attestations were broadcast in the network. With the increase in validator sizes and the number of these untimely attestations, this cache quickly filled and forced us to replay several times the same state. We decided to release a fix that will strengthen Prysm in the case of such events.
