Mining Alephium has a number of advantages over conventional proof-of-work blockchains. Here are some of them:
Ecofriendly: Alephium reduces energy consumption by a significant amount compared to other mining technologies.
Scalability: Due to the sharding of Alephium, it can handle larger transaction volumes. This is important for DApps. Alephium is a platform that developers and miners alike find appealing due to its scalability.
Assurance: The network is more secure because of the decentralized structure. It would be more difficult for an attacker to attack a network if he had to compromise multiple shards simultaneously.
Efficiency: Since miners are operating inside their shards there is less competition, leading to a more efficient use of resources. For miners that want to be sustainable, Alephium is a good option.
