Cardano blockchain founder Charles Hoskinson said in a post on X that he plans to launch a decentralized social media platform in Brazil after the Brazilian Supreme Court banned Elon Musk's social media platform X. "Although Brazil silenced our brothers and sisters on the X platform, their work will continue and is important to all of us, and I can't wait to recruit many Brazilians to help us build a decentralized social network," he said.
