y is cumulative, not a rate. This is the mistake worth avoiding: y × total is how much has been emitted by that moment, so a block's reward is the difference between the curve at this block and at the previous one. There is no "daily rate divided by blocks per day" anywhere in the chain.
Rewards follow real time, not block count. Because it is a difference across the interval, a slow block pays proportionally more and a fast one less. The schedule cannot be accelerated by producing blocks faster.
After the period ends, emission stops. t is clamped to [0,1]; past 15 years the curve is flat and coinbase is zero. Nodes then earn from transaction fees alone.
On Bitcoin the miner who finds a block takes the entire subsidy and every fee in it, one account, the whole block, and the odds of being that account follow how much hardware and electricity you brought. On Ethereum the proposer takes that block's fees and MEV, and while issuance is shared with attesters, the chance of being chosen tracks how much capital is staked. In both, the reward concentrates where the resources are.
ZooBC pays the block's coinbase and its fees out across the nodes keeping the network running, weighted by their participation score, a measure of being online, relaying, and vouching for other nodes' blocks with receipts. Not hardware, not stake: the work of actually being part of the network. That is what the name means, Proof of Participation. A node earns because the network is better off for its being there, and a node that goes quiet earns less without anyone having to intervene.
Each block's coinbase and fees are shared among up to 15 winning nodes, one per second of the block interval, chosen in priority order by a participation-score-weighted lottery. A slow block pays more (more elapsed time) but still to at most 15 winners. With fewer than 15 active nodes, the reward is shared among all of them.
So "per node" above is an expectation over time, assuming every node holds an equal participation score. A node that stays online and relays honestly earns more than that; one that drops out earns less. Over a single block a node either wins or does not.
