Bitcoin developer Antoine Riard has withdrawn from the development of the Lightning Network due to security concerns and other reasons.

According to BlockBeats news on October 22nd, Antoine Riard, a Bitcoin security researcher and developer, has withdrawn from the development of the Lightning Network due to security issues and fundamental challenges facing the Bitcoin ecosystem. He believes that the Bitcoin community is facing a "difficult situation" as a new type of alternative loop attack puts the Lightning Network in a "dangerous situation". It is understood that the alternative loop attack is a new type of attack, in which attackers can use inconsistencies between various memory pools to steal funds from payment channel participants. He pointed out that solving this new type of attack may require changes to the underlying Bitcoin network, and "these types of changes require maximum transparency and recognition from the entire community, as we are changing the processing requirements of full nodes or the security architecture of the decentralized Bitcoin ecosystem".
