ChainCatcher message, according to CoinDesk, the Bitcoin inscription project OrdinalsBot claims it has minted the largest file ever on the Bitcoin blockchain: this is the last one in the series of 1500 'Pizza Ninjas.' Such files are referred to as 'four meggers' because their size is close to 4 MB, and they are considered valuable commodities among Ordinals collectors due to their visibility on the blockchain.

The size of the 1500th 'Pizza Ninjas.' file is 3.969429MB, mined by BTC mining company MARA Holdings (MARA) at block 873,893 on December 9 at 13:57 Beijing time (00:57 Eastern time).
