Between June 20 and December 20, 2024, the average blob size on Celestia was approximately 1.18 GB. However, in the past two weeks, this number has almost doubled tenfold, reaching an average of 11.4 GB. This is likely due to the NFT minting that occurred during this period, as well as more projects choosing to use Celestia as a data availability layer.
Similarly, the number of daily transactions on Celestia has increased significantly during this period. Using the same time period (June 20 to December 20), Celestia averaged approximately 44,000 transactions per day. In the past two weeks, this number has increased by more than 60%, averaging 71,000 transactions per day. (The Block)
