The Latest eth2 Update: Differential Fuzzing, Thin Clients, and More


Welcome To the fourth installment eth2 update. There There are many exciting developments this week. In Here are some highlights, including impressive eth2 client growth:


Differential Fuzzing Grant

Sigma Prime was awarded a grant to initiate Differential fuzzing efforts for eth2 clients. This A multi-tenant network launch is only possible if everyone works together to find consensus issues that can be addressed before the main network.

Fuzzing It is the process of throwing random inputs at software to see how it responds. When Fuzzing a single piece of code is usually about discovering entries that can lead to unexpected crashes. When We find such inputs and fix the software.

Differential Fuzzing is a different situation. Rather Instead of searching for failures in a specific way, we look for instances when different implementations have different outputs for the same input. In In a blockchain context, differential fuzzing is used to identify cases in which a sequence of blocks results in a different state for two clients. Ideally These cases are not common in production.

Thin Client Workgroup

Safe chain/Polar StarThe Ethereum Foundation has formed the Thin Client Workgroup for researching and developing eth2 thin clients. This The group was created to ensure that thin clients are first-class citizens of eth2. To They are now organizing a Monthly call This site is designed to facilitate customer research, specifications, and education.

Fragmented protocols like eth2 don’t allow for the creation of a rich ecosystem with thin clients and thin server servers. Even Clients can sync a segment of the protocol. For example, there are a few shards. Users will need information about contracts and accounts in another shard. While a client might not be able to sync the complete extra snippet efficiently, most clients will ask for information about specific accounts with quick tests.

Tune In the next Thin Client Workgroup Call Stay abreast of all things light on Eth2.

eth1-> eth2

In In the early days eth2, the transfer of ether from existing ethereum chains (eth1) and new beacon chains (eth2) will only be one-way. That The reason is that ether transferred to stake on eth2 won’t be transferable (to start with) back to the eth1. Choosing A single directional transfer in validation can be used to reduce the risk profile of eth1 as well as to speed up the development cycle on the eth2 platform without the need to fork eth1. There There is some movement to create a two-way bridge. I’ll The discussion about bridge mechanics, trade-offs, and other topics will be saved for a later posting. Today I’d like to delve into the subject. What How does one-way transfer work?

In The existing Ethereum PoW chain, We will implement Contract validator eth2. This A contract can only perform one function. Deposit This takes a number of parameters to initialize a validator (eg withdrawal credentials
