Algorand's v4.0 rollout earlier this year brought a fresh approach to network participation. Here's what changed: if you're holding 30,000 ALGO or more, you can now generate block rewards through two paths—either run your own node or delegate your stake to a third-party operator. The reward structure splits transaction fees between block proposers and the network, with the foundation kicking in additional incentives that taper over time. It's a shift toward making participation more accessible while keeping economic incentives aligned with network security.
