A say in how much the network gives. Each validator sets a philanthropy percentage, from 0 to 100, and that share of the new AGAPE in every block it proposes goes to the treasury.
Rewards for securing the network. Each validator publishes two rates on chain: its philanthropy percentage and its commission. When it proposes a block, the block's new AGAPE is split by formula: the philanthropy percentage goes to the treasury, the commission is taken from what's left, and the remainder is shared by everyone staked with the validator, in proportion to their stake. With 40% philanthropy and 5% commission, 100 new AGAPE becomes 40 for the treasury, 3 for the validator and 57 shared by stake.
Holders who don't run a node can delegate their stake to a validator, and in choosing one they choose its philanthropy percentage. The wallet lists validators by that percentage first, and delegators claim their share from it.
Run a node, and register with at least 10,000 AGAPE of your own stake. Every hour, the 100 validators with the most stake form the set that proposes and votes on blocks.
Stay online and sign honestly. Signing two conflicting blocks costs a validator 5% of its stake and its place for good.
