Square Inc. Chief Executive Officer Jack Dorsey said the digital-payments company is considering building a Bitcoin hardware wallet, a device that holds the digital currency but isn’t connected to the internet.
Hardware wallets are used by cryptocurrency investors who want an extra layer of protection from holding their coins on a web-enabled device. Wallets let crypto users hold coins and include a public and private key that acts as a blockchain address. Hackers have become adept at very sophisticated methods of stealing crypto that include taking over someone’s phone to access the private keys that are necessary to move Bitcoin, Ether and other digital assets.
