Software company Block.one raised $4 billion for its EOS project from investors on the promise that the blockchain platform could change the way the internet works. But infighting among the software’s fragmented developers shows it still has a way to go before the platform lives up to the hype.

More than 200 volunteer developers working to launch EOS spent a fraught three hours on a conference call Friday arguing about issues related to the platform’s launch. A transcript of the call was posted on the social-media site Reddit, and two participants confirmed its validity to The Wall Street Journal.

Block.one couldn’t be reached for comment.

Since the Friday call, EOS’s tokens have fallen roughly 20%, cutting $4 billion off its market value, currently at about $10 billion.

The platform technically launched on Saturday after the volunteers smoothed over their differences during a second meeting Friday, broadcast publicly on YouTube. The platform isn’t yet available for public use.
