K Framework

The K Framework is a rewrite-based executable semantic framework used for defining the syntax and semantics of programming languages. It allows developers to formally verify programs by defining the language in which they are written.

In the context of blockchain, the K Framework is used to create formal models of smart contract languages, enabling the verification of specific contracts. By defining the semantics of the language, it allows for the automatic generation of proofs that a contract is correct.

This is a powerful approach that can be applied to various smart contract platforms. It provides a comprehensive way to ensure that the code is not only correct but also behaves as intended by the language specifications.
