PANews reported on December 10 that according to CoinDesk, the Bitcoin inscription project OrdinalsBot claimed that it had minted the largest file ever on the Bitcoin blockchain: this is the last in a series of 1,500 "Pizza Ninjas." Such files are called "four meggers" because they are close to 4 MB in size and are considered valuable commodities among Ordinals collectors due to their visibility on the blockchain.

The 1500th "Pizza Ninjas." file is 3.969429 MB in size and was mined by BTC mining company MARA Holdings (MARA) on block 873,893 at 13:57 Beijing time (00:57 Eastern time) on December 9. To be clear, it is technically impossible to inscribe a file exactly 4MB, but the term "four meggers" refers to files larger than 3.5MB.
