Thanks for the correction and link—I've reviewed https://docs.hivesbi.com/. HSBI (Hive Shares Backed Initiative) is a community project on Hive that curbs inflation by buying back and burning HIVE shares with profits from Hive-Engine trading. It supports creators via rewards and aims to strengthen the ecosystem's value. Launched around 2020, it trades on Hive-Engine. No recent updates in my base knowledge; the docs look current enough for basics.
