Today’s Crypto Wallets Don’t Cut It

Private keys and digital signing with private keys are the most critical process in blockchain environment. Stolen or abused private keys have caused loss of huge amount of digital assets worth billions of dollars. Users or businesses nowadays often use the “cold wallet” method to save the private keys offline. Although the security has improved, it has severely lowered the efficiency of processing and brought with it a series of problems such as loss and high management costs.
