What determines the control of a safe house in the digital world? It's simple: the key to the safe house. Whoever holds the key is the owner of the safe house. This key is the private key of asymmetric keys in cryptography. The private key is the core of our digital world. Users declare their sovereignty in the digital world through signing and encryption. So it can be considered that the private key is our incarnation in the digital world, as important as our body in the physical world. We must do everything possible and make every effort to ensure its security. This is the core work of our project.

So how do you control your own private key?

In the past, wallets all used mnemonics. The mnemonic solution is very risky. I personally have a tragic example of losing the mnemonics of my wallet. Mnemonics are indeed useful, but they are only suitable for professionals, not for ordinary people who do not understand this technology, because mnemonics have a single point of failure risk. The most mainstream solutions now are MPC wallets and AA wallets (account abstraction), which solve the single point of failure problem. MPC actually turns the management of a private key into multiple people (that is, multiple private keys) to jointly manage a private key, which is suitable for teams but not individuals. The AA wallet is very powerful, but after careful analysis, users still need to use another private key to manage the AA wallet. This is like a nesting doll. It seems that the AA wallet does not need to manage the private key, but in fact there is still a private key on the outside. In the final analysis, these two solutions do not solve the problem of how individuals manage private keys, and are not suitable for individuals. Moreover, these two solutions can only be used for signature authorization, not for encryption of data (because there is no private key, or no fixed private key).

Our solution has two key points. One is multi-path recovery to avoid single point failure. We now support three recovery methods: mnemonics, guardians, and smart privacy. We are also developing simpler and more convenient recovery methods, such as smart inheritance solutions implemented using smart contracts, so you don’t have to worry about losing your wallet.

The other is to use the user's own multi-dimensional data to provide multi-level protection for the private key, so that the user can recover the private key without additional memory and record. These dimensional data include the user's self-awareness, memory, emotion and other spiritual data (such as personal commonly used passwords, things that are deeply remembered), as well as physiological characteristics such as fingerprints and pupils (such as fingerprint recognition), and also include data in social relationships (such as mobile phone numbers, ID numbers, social account logins).

We are also developing an AI assistant, with the goal of achieving a user experience similar to account recovery in a centralized system, so that no one has to worry about account loss or attacks. Users do not need to remember easily forgotten passwords, nor do they need to copy and save error-prone strings, and can retrieve their accounts independently.

In general, private keys are very important to us, and we need to improve our understanding of private keys. They are almost like life and property. For more detailed information, you can learn through the TinyVerse Space app.
