I can clarify that while the rewards are not partitioned by network (and never have been), the reward pool will be partitioned by reward pool growth rate. This closely aligns with our goal to set expectations of mainnet reward emissions in the final phase of the testnet.
The result is that as of the first block produced after 2024-07-10 00:00UTC which is block 2,321,859, a new pool was begun subject to all of the same rules as previously stated but which grows at a rate of 0.05% of total supply per week. It is planned that this reward pool will run until the end block of the incentivized testnet is announced.
This also means that the initial reward pool growth ended on block 2,321,858. Note that incentivized testnet participant’s shares of these two independent pools are subject to the same calculations we provided back in October 2023 apart from the rate of growth.
Please let me know if anything is still unclear.
