Cardano, with its token ADA named after mathematician Ada Lovelace, is one of the largest layer-1 blockchain solutions by market capitalization. Input-Output, Emurgo, and the Cardano Foundation drive the project. Cardano uses Ouroboros, a proof-of-stake (PoS) consensus mechanism, where ADA holders delegate their funds to stake pools. Validators are paid by the Ouroboros protocol with a fixed pool cost and an optional margin, and staking rewards are assigned to all delegators. The Cardano ecosystem has expanded significantly, offering full-node and light wallets, browser plugins, and mobile apps. Staking ADA in a self-custodial wallet is one option that eliminates counterparty risk. The Yoroi wallet is used to create self-custodial wallets for Cardano assets. To stake ADA, holders can choose a pool from over 3,000 staking pools on the Cardano network. Stake pool search tools and dedicated portals like PoolTool and explorers like Cardanoscan and Cexplorer help in this. Troubleshooting common issues like wallet synchronization issues, transaction errors, and staking rewards not received is critical for smooth staking experiences.
