The CNCAla ISPO is about to start: In Epoch 377 / November 21st. There are 20+ ISPO member pools which participate. All delegators of these pools can earn their regular ADA staking rewards and additionally they get CNC tokens which can be later used to redeem NFTs from partners.
By staking ADA to an ISPO pool, delegators enable the pools to make donations from their pool rewards to Tetikasa Ala, which allows them to plant trees in Madagascar and fight drought.
