Ecency chat is 2nd layer. It requires a pin/key to keep it private and decrypted. Ecency does not save your pin. If you lose it you can create a new one, but all chat history will be lost.
The delegation from Eceny is approx 200 HP and gives accounts more voting power, so we all benefit from their larger votes! The delegation also allows the opportunity to earn bigger curation rewards, and is especially valuable for helping small accounts grow!
A new script is being written for Ecency curation. We will have more details soon. Right now curators are reviewing and giving votes to posts published using Ecency.
