The former CTO of Tron, who left the project to launch a competing blockchain, has denied accusations of embezzlement, bribery and infringement that were levied by Tron founder Justin Sun.

The dispute between the two emerged after Zhiqiang Chen announced in a May 10 Medium post that since his departure from Tron in January 2019, he has been building "a new TRON" called Volume Network.

Chen, who joined Tron in late 2017 as its technology chief shortly after following an initial coin offering, said he feels “very sad” that Tron is, in his view, no longer decentralized. He said the delegated proof-of-stake mechanism Tron uses is “pseudo-decentralized,” adding:

"The technology platform of TRON was built by me," he added. "I certainly know that the real Internet applications cannot function in TRON network at all currently. The TRON ecosystem is still far from commercial applications."

According to the white paper of Chen’s Volume Network, major team members of the project also come from Tron, including Xiaodong Xie, a former Tron blockchain developer, as well as Jinchao Zhu, a former dapp product manager at Tron.

At the heart of Sun's accusations is the contention that Chen and others violated the law as well as company rules, asserting that the group had been fired in January 2019 following "verification done by TRON's discipline department."

Chen’s post appears to have drawn backlash from Tron’s Justin Sun, who said via his Weibo account on May 11 that Chen, Zhu and Xie were fired in January with a series of allegations against them.

As Sun said on Weibo:

However, Sun himself did refer to Chen as the CTO of Tron in a June 2018 Twitter post.

Sun did not specify what material or evidence Tron has obtained and submitted or to which "justice department" he was referring.

On Sunday, May 12, Volume Network published a second blog post in response to Sun’s accusations. Further, Chen said he would consider either a civil or criminal lawsuit against Sun for libel and defamation if he continues to make such accusations.

When reached for comment by CoinDesk, Chen said he denies all of Sun’s allegations.

“If I am really a suspected criminal, it is too late to ‘run away,’ [and] I should not create a new blockchain project ... and find technical talents to join my team, shouldn’t I?” he said in the blog post, stating:

To deny Sun’s characterization of him as just an “ordinary tech guy,” Chen also linked to a Tron GitHub repository from April 2018 with his name listed as the company’s CTO.

“To be frank, I surprised that I turned into ‘the employee of the technology department’ overnight," he further stated. "As Justin’s point of view who has immigrated to the United States, technicity is just the most insignificant and ordinary ‘workers’, which are tools to make money for him. I can be treated as a foolish person, but the entire TMT industry technical personnel’s IQ cannot be insulted.”
