So, how does SHM improve trust on the open web? We build on a system called public key cryptography. You have a private key, basically random data, that is stored on your computer or phone. And it has a public key, which acts like a username. But it’s not registered with us, anyone can independently create these identities. Any time you do something in the system, it is signed by your private key. Thanks to the magic of cryptography, anyone can verify that signature against your public key. And you can link new devices by signing a message that gives account access to a different private key, on the new device.
