Energy consumption: Proof of Work consensus algorithms require significant amounts of computational power, which leads to high energy consumption. This has environmental implications and raises concerns about sustainability.\n\n2. Centralization: As mining becomes more competitive, it tends to favor large-scale operations with access to cheap electricity and advanced hardware. This can lead to the concentration of mining power in a few hands, undermining the decentralized nature of the blockchain.\n\n3. Security: PoW blockchains are susceptible to attacks such as 51% attacks, where a malicious actor could potentially gain control over the network by pooling their computing power.\n\n4. Scalability: The performance of PoW blockchains tends to degrade as the number of transactions increases, resulting in longer confirmation times and higher transaction fees.\n\nTo address these issues, Zano has adopted the following methods:\n\n1.
