- Alice wants to share a secret message to a group of people she trusts.
- This message can only be shared in a decentralized system (not blockchain!!), where everyone can see every message sent.
- Once the message is sent, it can not be changed, and neither can the data attached to it, like a decryption key.
- There is no direct communication between Alice and the people in her trusted group, she can only send messages that everyone can read.
- The people in her trusted group can change, if someone enters the group, they can now read the secret message, and if they leave, they cannot read it anymore.
