Security Researcher Departs Lightning Network Team

Antoine Riard Exits Lightning Network Over Security Concerns 

Antoine Riard, a security researcher and developer, is leaving the Lightning Network's development team, citing security concerns and challenges to the Bitcoin ecosystem. Riard highlighted the fear of replacement cycling attacks, which target Lightning Network payment channels. He thinks that addressing these attacks may need changes to the underlying Bitcoin network, necessitating transparency and community buy-in. The Lightning Network, a second-layer solution for Bitcoin, faces difficulty and user experience concerns. While it has acquired popularity, with $159.5 million in total value locked, it's a small figure compared to Bitcoin's $587 billion market capitalization. Riard will pivot to Bitcoin core development, cautioning of upcoming challenges.
