What is the Name of the Network with Chain ID: 10?

There is some confusion within the community regarding the name of the network with Chain ID: 10. Currently, the following four names are being used:

  1. Optimism
  2. OP Mainnet
  3. OP-Mainnet
  4. OP

Optimism

This name was used before last year’s name change. Currently, it refers to the Superchain ecosystem.

OP Mainnet

This name started being used after last year’s name change. For example, it is used in this blog.

OP-Mainnet

This name is used in the Superchain registry. The Superchain registry is used as an off-chain source of truth and is considered the most reliable source, but I have never seen the name OP-Mainnet being used in practice.

OP

This is an abbreviated name due to the general nature of the word “Mainnet”. There is a file named op.yaml in the Superchain registry. In practice, Debank has adopted this name.


As you can see, there is inconsistency in the name of the network with Chain ID: 10, which is causing confusion. Could you please share your opinion on this matter?
