Thank you for taking the time,
Those blocks were generated a year ago and we have since been working to improve Tittiecoin.
Thank you again for your information.
Update: It turns out that the sudden increase in block reward is due to transaction fees. For example, for TTC block 2372, the block reward is 8008 TTC. However, one transaction pays a transaction fee of more than 58% of the transferred value. This results in a transaction fee of 10000 TTC, which goes to the lucky miner of this block.
