Ethereum 2.0 testnet is about to launch, can host 100,000 validators

According to Trustnodes reported on February 12, the Ethereum 2.0 testnet capable of carrying about 100,000 validators is about to be released and is currently undergoing stress testing.

Lighthouse developer Paul Hauner says:

"It is running the state transition code in version 0.10.1, which is the latest multi-client interoperability specification.".

Another Lighthouse manger, Age Manning, said on Saturday that they are working on a final update to integrate all the mainnet functions and hope to complete it this weekend. He said:

Nishant Das, a developer of Prysmatic, another Ethereum 2.0 client, said they are updating to the 0.10.1 specification. Once this step is completed, they will develop interoperability.

"I want to try to run a local Lighthouse testnet, successfully interact with it with a Prysmatic node, and be able to successfully interoperate with the Lighthouse node. Then reverse the operation and use the Lighthouse node to interact with the Prysmatic local testnet."

Although Manning said that they are focusing on upgrading to the 0.10.1 specification and then doing some interoperability.

Interoperability is the last stage before full launch, in which developers let different client nodes "interact" with each other to create a multi-client testnet.

Obviously, you can run it on the latest raspberry pi with 4GB of memory. Horner says:

"On past test networks, people have done this successfully with smaller validator counts (16k).

The new version is 100k, but I think the latest optimization load is similar. I haven't proven it yet, but my gut tells me it will work on this testnet as well. " He further stated that they are optimizing to run on cheap hardware.

It's unclear whether this will work on iPhone or Android, but Nimbus, a mobile Ethereum browser developed by Status, is using the first mobile Ethereum 2.0 testnet.

The three clients Nimbus, Lighthouse and Prysmatic seem to interact well with each other. It is best to use these three clients when the mainnet starts, but if one of them is behind, you can only use two.

All three clients seem to have sufficient economic resources to support them. Both Nimbus and Lighthouse are hiring developers.

Due to the design of staking rewards and punishments, these three clients are necessary to achieve selectivity and diversity. They will have a lot of work for at least two years. The first is to launch sharding. , Then improvement.

As you know, sharding parallelizes the Ethereum blockchain to increase its capacity by the number of nodes.

The new Proof-of-Stake (PoS) Beacon Chain did not have complete shards from the beginning, but there are some shards called subnets. Lighthouse's Michael Sproul says:

"A sharding subnet is a group of nodes responsible for aggregating proofs before broadcasting. Instead of having 100,000 validators send each other their proofs, each committee sends their proofs between them, building a large aggregated proof, and Broadcast the aggregate to everyone. "

So this may be the way sharding works, a group of nodes "talk" to each other, and then send their "chat" to another group of nodes.

This means that not only will Ethereum start pledges this summer, but sharding will also start at that time.
