# Why Popular Permissionless Chains Fall Short

Popular public blockchains, despite their transparency, lack the inherent ability to segregate data by privacy needs, often requiring complex off-chain solutions or additional privacy layers. These solutions, however, introduce new vulnerabilities and dependencies, complicating compliance efforts. The absence of fine-grained privacy controls makes it nearly impossible to meet standards like GDPR and PCI without compromising the network’s integrity or adding significant complexity.

Kalp, with its ability to natively segment data through subnetworks, avoids these pitfalls by offering **built-in data privacy and compliance** capabilities. This approach not only streamlines compliance but also simplifies network management for developers, enterprises, and other stakeholders in sensitive industries.
