Luke Dashjr has faced criticism for refusing to allocate BIP numbers for Casey Rodarmor's proposal as a Bitcoin core contributor. Luke Dashjr believes that Ordinals is a spam protocol, so he did not take the proposal seriously and did not allocate a BIP number for it. Luke Dashjr believes that Ordinals and its Inscriptions on the blockchain use Bitcoin's Taproot and Segwit discounts to cheaply embed a large amount of data. He has called Ordinals an "error" that needs to be fixed. The original intention of Bitcoin was to process transactions, not JPEGs. Luke Dashjr even filters out Ordinals transactions from many of the blocks mined by his mining pool OCEAN. It is reported that Luke Dashjr has made many contributions to Bitcoin Core over the years, including support for SegWit during the Bitcoin block size war. The Bitcoin network eventually adopted SegWit through a user-activated soft fork in 2017. SegWit made it possible to cheaply store more data on the Bitcoin blockchain without increasing the block size. Bitcoin supporters believe that this was a suitable compromise for such a controversial topic, and Luke Dashjr became one of the most active Bitcoin developers. He eventually founded several companies, including the Eligius (now OCEAN) mining pool.
