Why do I need to submit a transaction?

In sproof, each change of your profile is represented by an event. Multiple events can then be embedded into a single transaction. In order to submit your events to the blockchain you need to digitally sign them with your private key. Therefore, you need to enter your passphrase before your events can be sent to the blockchain. Once the transaction is submitted, it will take up to 10 minutes before your changes are available in sproof.
