Shared Security

Shared Security is a model where multiple blockchain networks or applications rely on a single, unified validator set or consensus mechanism to protect their assets and data. Instead of each chain having to build its own security from the ground up, they tap into the existing, robust security of a parent network.

This prevents the fragmentation of security resources and makes it significantly more difficult for attackers to target smaller chains within the ecosystem. It is a highly efficient way to bootstrap new networks, as it allows them to focus on innovation and application development rather than the complexities of maintaining a secure validator set.

The shared security model is essential for the growth of modular blockchain architectures, where many different chains can coexist and interact safely. It also creates a stronger economic incentive for validators, as they are rewarded for securing the entire ecosystem rather than just a single, isolated chain.
