The fork block at 862,866 will see the per-block reward reduced to 400ETN, and this will be followed up by three more reward halvings in the future:

• Block 1914066 (year 2024): reduction from 400ETN per block to 200ETN
• Block 2965266 (year 2028): reduction from 200ETN per block to 100ETN
• Block 4016466 (year 2032): reduction from 100ETN per block to 50ETN

After the 2032 halving, no more block reward reductions are planned until the maximum supply of 21 billion ETN is reached. Tail emission: block reward gets reduced from 50ETN to 25ETN per block.
