Very true.
You can see a real-time graph of the block reward here: https://electroneum101.com/statistics/block-reward.php
Electroneum has a smooth emission curve with a tail. It looks a lot like the Monero emission curve shown in this image.
Smooth emission curve
Smooth emission means that the block reward is recalculated after each block (as opposed to Bitcoin’s recalculation every 4 years), and thereby creating a smooth decline rather than Bitcoin’s sharp drop. The block reward is a function of the total supply of Electroneum and the amount of coins already mined, and calculating it involves shifting bits (see this article written for Monero, on which Electroneum’s code is based).
Tail emission stage
The tail emission means that at the point where the calculated block reward reaches below a certain value (0.6 ETN in the current code), the block reward will stay at 0.6 ETN into perpetuity. Miners will also, of course, receive the fees associated with the mined transactions.
Block reward penalties
As you’ll see in the graph of block reward above, some blocks have a slightly lower reward than the norm due to the miners trying to squeeze too many transactions into one block, thereby exceeding the block size limit, and getting penalized by having their reward reduced. This is a security feature implemented to prevent an attacker from flooding the blockchain and getting a slight time advantage over other users that first need to download and sync the flood of new transactions before continuing their mining processes.
The block size limit also varies dynamically based on the amount of transactions processed in previous blocks. So it will increase during times of high transactions volume so that the transaction throughput scales up with demand.
