+How about these specs:
+* 1 MB, height < 210000;
+* 2 MB, 210000 <= height < 420000;
+* 4 MB, 420000 <= height < 630000;
+* 8 MB, 630000 <= height < 840000;
+* 16 MB, 840000 <= height < 1050000;
+* 32 MB, height >= 1050000.

+> Specification

+> 1. Increase the maximum block size to 2MB when block 630,000 is reached

+>
+> 2. Increase maximum block size to 4MB at block 840,000.

+> 3. Increase maximum block size to 8MB at block 1,050,000.
+>
+> 4. Increase maximum block size to 16MB at block 1,260,000.
+>
+> 5. Increase maximum block size to 32MB at block 1,470,000.

+> Backward compatibility

+> While more comprehensive solutions are developed, an increase to the block
