According to Foresight News, the IOTA Foundation announced the launch of the IOTA 2.0 public testnet. This update introduces a decentralized proof-of-stake (PoS) mechanism, replacing the old coordinator-driven system and canceling the traditional proof-of-work (PoW) mechanism, improving scalability and reducing environmental impact. IOTA 2.0 aims to create a more secure, scalable and environmentally friendly network, and invites the community to participate in testing and optimizing this process.
