The concept of implementing soft forks within the Bitcoin network is detailed through an approach called CUSF, as coined by Paul.

This methodology diverges from the traditional mechanism of integrating changes directly into the core repository. Instead, it allows for the application of new rules or modifications via an external validator. This process operates on the premise that a soft fork is only successful if there's a broad economic consensus among node operators to adopt and enforce the new rules.

The method of utilizing invalidateblock as a means to programatically reject blocks introduces a nuanced way of enforcing soft forks without requiring immediate updates to the core codebase. This strategy presents a solution to a common reluctance among participants to swiftly upgrade their software, addressing concerns over rapid changes and the potential introduction of unwanted alterations. The out-process validation not only simplifies the review process by focusing on the new rules but also facilitates compatibility with older versions of the software, thereby overcoming challenges related to signaling for soft forks.

Moreover, the adoption of out-process activation for soft forks emphasizes the importance of community agreement and the economic incentives of node operators. By decoupling the enforcement of new protocols from core software updates, this approach offers a more flexible and inclusive path toward consensus and adoption of changes within the blockchain ecosystem.
