The use of Practical Proof of Stake (PPoS) algorithm as a consensus protocol for the Coremultichain project is a good choice, as it provides scalability, security, and decentralization. PPoS algorithm allows for faster transaction times, lower fees, and more secure networks than traditional Proof of Work (PoW) algorithms. It also allows for more decentralized networks, making it a suitable choice for blockchain projects.
