Is Luna a new public chain? Is Lunc an abandoned public chain?

This statement is not accurate. The specific differences are as follows:

Relationship and Origin:

Luna: It is a new native cryptocurrency on the Terra 2.0 public chain, which is the new chain after the hard fork of the original Terra blockchain.

Lunc (Luna Classic): It is the cryptocurrency on the original Terra 1.0 public chain, renamed LUNC due to the decoupling of UST and the collapse of Luna.

Characteristics and Differences:

Luna: It is not pegged to any stablecoin, has a new airdrop plan, and its total supply and market value are different from Lunc.

Lunc: It is still connected to the USTC stablecoin and is affected by the old chain's ecosystem and historical issues.

Ecosystem and Development:

Terra 2.0 aims to rebuild the ecosystem, attracting developers and users, with Luna's price closely related to ecosystem development.

Lunc represents the legacy issues of the old chain, and its price and value are influenced by historical collapse events.

In summary, Luna is not a new public chain but a new cryptocurrency on Terra 2.0; Lunc is also not an abandoned public chain but a cryptocurrency on the original Terra 1.0.
