Key escrow refers to a system where cryptographic keys are stored by a trusted third party. The idea is that the keys can be accessed or decrypted by this third party if necessary, usually for legal purposes or regulatory compliance.In cryptocurrency, key escrow can be controversial. Users often value privacy and control over their assets, and they may see key escrow as a risk. If a third party holds a key, it creates a potential vulnerability. This can allow unauthorized access if the storage is compromised or if the third party misuses the key.Supporters argue that key escrow could provide a safety net, especially in cases of lost access due to forgotten passwords or lost devices. However, the balance between security, privacy, and convenience remains a topic of debate among users and developers. As a result, many prefer private keys to be entirely self-managed to maintain autonomy over their assets.
