Gartner, a well-known research and consulting firm, said that the hardware and software encryption wallet is about to enter the "Trough of Disillusionment", but the future seems to be bright, because there will be better than private keys. s Choice. Avivah Litan, an analyst and research vice president of Gartner, said: "There are a lot of hype around the hard-software encryption wallet, because they essentially give the encrypted investor and the user an interface to make it their own 'bank'." Litan added "In the next 2-5 years, I believe that the market will see a lot of innovations in alternative access security methods, such as MPC (multi-party computing), which will replace the private key management currently used in encrypted wallets, and private key management. It is the Achilles heel of blockchain applications. Private key management and recovery are key functions for maintaining blockchain account access and data security."
