As of the most recently completed Solana epoch, the Top 100 SOL Stakers by SOL Staked & their Annualized Return (in SOL) as of last epoch. Sometimes top stakers fumble from delegating to worse validators. Validator quality (and commission rates) may impact APY.

Validators can both pay and receive rent from pruning Solana addresses. As of Nov 2023, SIMD-84 has been proposed to turn off rent collection.

Top Validators (Block Producers) follow a similar distribution. Unlike staking rewards where validators only keep commission, they keep a full 50% of transaction fees for blocks they produce (vote transactions + user transactions). The other 50% is burnt (removed from circulation). Some validators seem to slightly outperform their Fees/Block, but it may be random spikes in demand.
