Cardano's Shelley upgrade has seen fast growth, with hundreds of stake pools joining the network within 24 hours of its July 29 launch. Users can delegate their ADA cryptocurrency holdings to these various independent pool operators and earn staking rewards.
At its post-launch peak, Cardano had 481 stake pools in operation, according to a press release. However, that number is constantly changing, and it currently has 416 active stake pools at the time of writing, according to AdaPools.org.
