`My children have been writing good code since they were 12 years old. They are much better than the nonsense code that Palmer sent me,` Musk wrote on Twitter on May 31.

Musk’s reaction came after Palmer – one of the people behind the meme coin Dogecoin – criticized the Tesla CEO on Australian site Crikey.

Jackson Palmer is one of two creators of Dogecoin.

Palmer said he first messaged Musk on Twitter a few years ago, when he created a bot to help detect cryptocurrency scams in posts.

`Musk contacted me to approach that bot and it was clear he didn’t understand encryption,` Palmer said.

Palmer parted ways with the Dogecoin project in 2015, citing a `toxic` culture.

`Palmer always forgets that he has never written any code related to Dogecoin,` Musk said.

In the next post on May 31, Palmer called on Billy Markus, also the co-founder of Dogecoin, to testify against Musk’s accusations.

Markus then tweeted separately: `The guys after me and Jackson Palmer did exponentially more programming for Dogecoin based on the base code. I think I wrote about 20 lines of code and copied the rest.`

In response, Musk praised Markus for being humble.

Markus is a former IBM software engineer and Palmer is a former Adobe software engineer.

Also sharing with Crikey, Palmer commented that Musk dishonestly makes money by deceiving people.

He also suggested that Twitter users might be fascinated by Musk’s posts and want to make friends or get rich by collaborating with him.

In the development history of Dogecoin, Musk is one of the indispensable factors because he has publicly supported this digital currency many times.
