COINOTAG News reported on October 24 that the Ethereum smart contract language Solidity will diverge into two tracks: Classic Solidity and Core Solidity, signaling a deliberate split to balance production reliability with long-term innovation.

The current production standard remains Classic Solidity, backed by a trusted compiler, yet the development team notes underlying instability in the language’s evolution, as reflected in the 0.x release series, with the latest tag at 0.80.30.

By contrast, Core Solidity is a ground-up redesign featuring a new type system capable of generics, first-class functions, and algebraic data types, though the project remains in the prototype stage.

Solidity 1.0 is positioned to mark Core Solidity’s stability threshold, aiming for the default frontend, while a staged migration plan uses a sequence of major version bumps to progressively align Classic Solidity syntax with Core Solidity.
