## Key Share Lifecycle

The key share lifecycle encompasses the generation, distribution, usage, rotation, and destruction of secret key shares. Each stage requires rigorous security protocols to ensure that shares remain protected from unauthorized access.

Rotation is particularly important, as it allows for the periodic refreshing of shares to invalidate potentially compromised fragments without changing the public key. This process maintains the long-term security of the assets under management.

Lifecycle management also involves monitoring the status of participants and ensuring that the threshold is always met. Proper lifecycle tracking prevents "share drift," where shares are lost or incorrectly stored over time.

It is a critical operational component of institutional-grade custody and decentralized bridges. By formalizing the lifecycle, organizations can implement automated security policies that reduce human error.

The goal is to ensure that the security properties of the system are maintained throughout the entire duration of the asset's existence.
