Network

zkSync Era

Provide a brief description of the feature you would like to see implemented.

Other chains (L1 and L2) have good documentation about running a node,
I found nothing useful for zksync

Who does this feature request benefit the most (users, developers, protocol, etc.)?

node holders

Hey @zxsimba 👋

You can expect this to change in the future when we open the network up to decentralize network participants, for the meantime you can review the docs for running and developing zkSync Era node here, and an external node here.

Thanks, I didn't know that zksync is not decentralized yet.
But I am wondering if the source code or binaries of node is not released, how ankr provided an rpc interface to zksync?

[dutterbutter]

They are running an external node here. You can run an external node that provides read-only privileges to the network today. You can also see the source code, we are open-sourced entirely.

Great, and the final questions:
The network is not decentralized yet : is it due to lack or incompleteness of consensus algorithm or its implementation?

Is there any estimate on when the network would be open to decentralization?
