Is offline storage the only answer?
Many advice to keep the seed phrase safe, but there isn’t a 100% perfect way no matter how much you search through. Storing offline is mainly recommended, but there is a possibility of damage and loss. In particular, online backup is perceived as very negative. Some online password management services introduce that it is possible to store the recovery text of the private key. However, if you forgot to log out of the account, the recovery text might get disclosed. Or when the service gets hacked, there is again a possibility of losing your assets. As such, it is a common perception that online storage is not secure enough.
But what if you could save and recover the seed phrase that can only be accessed by ‘you’ whenever you need it? MasterKey is a solution to prevent digital asset loss by storing the seed phrases of various private keys before they are lost. Providing B2B and B2C enterprise-grade private key management solutions as a way to protect private keys that can access digital assets, is the safest way to protect your digital assets. You can also restore(recover) the seed phrases after paying a certain fee if an issue occurs.
How is MasterKey safe?
The core of storage and recovery is security, stability, and recovery speed. This could be possible because of the R3 Corda network, which is a private blockchain technology for institutions. Corda network is a communication network between nodes agreed upon in advance and is a permissioned blockchain that values rapid transaction processing and privacy, such as having to go through the KYC process to verify the identity of new network participants.
The stored seed phrases are distributed and stored in the financial cloud through several R3 Corda nodes. Each stored seed phrase is encrypted into a password through a blockchain algorithm and managed, making it impossible to hack. Before storage, the user also has to complete the identity verification system in 3-steps(e-mail, SMS, name authentication) and recovery is possible only when the identification information matches the owner. Therefore, the recovery phrase stored in MasterKey cannot be read or damaged by anyone other than the owner.
