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.↵↵2. 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.↵↵3. 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.↵↵4. Scalability: The performance of PoW blockchains tends to degrade as the number of transactions increases, resulting in longer confirmation times and higher transaction fees.↵↵To address these issues, Zano has adopted the following methods:↵↵1. Transition to Po","a":"Switch to more environmentally friendly mining algorithm: The Zano project team has transitioned from the traditional SHA-256 mining algorithm to the more environmentally friendly Ethash algorithm to reduce energy consumption."}]}],"pr":"fced264139a6041117db9e3ca98b8d2c3f39672d79b8c9409c1e42411c846cab"}
