This video is layman's explanation of posting keys and authority. It is a response to a request by @reggaemuffin.
Basically there are four keys in Steemit and each of them carry different levels of security and have different degrees of access to your account.
The four keys are
- Owner Key
- Active Key
- Posting Key
- Memo Key
Refer to the video for a pretty simplified explanation.
Thank you.
