## Problem
<!-- A more elaborate description of the problem and its context. This section should explain what motivates the writing of the CPS document. -->
The motivation behind this CPS arises from the current limitations faced by Stake Pool Operators (SPOs) within the Cardano ecosystem. At present,
SPOs are restricted to using key-based credentials for their 'Cold Key,' which prevents the use of script-based credentials to share ownership and
control of the stake pool. This limitation creates challenges in terms of security and multi-party management.

By enabling script-based credentials for the pool keyhash, SPOs would have the ability to implement multiple signers, significantly enhancing security.
With this approach, if one signer’s key is compromised, it would be possible to rotate the keys without needing to change the script hash, ensuring
continuity and reducing the risk of security breaches. Moreover, this would allow a more collaborative form of pool ownership, enabling multiple parties
to jointly control the pool, rather than relying on a single keyholder for all decisions and changes. This flexibility would foster greater decentralization,
improve operational resilience, and mitigate risks associated with single points of failure.

The [current ledger design](https://github.com/IntersectMBO/cardano-ledger/blob/master/eras/conway/impl/cddl-files/conway.cddl) associates five types of credential with stake pool operators:
