Solana is engineered for widespread, mainstream use by being energy efficient, lightning fast, and extremely inexpensive.
Many of the core Solana builders, like co-founder Anatoly Yakavenko, have a background in building cell phone networks. That means that they are singularly focused on building for scalability (the ability to grow) and efficiency (the ability to get the most information across with the least amount of resources). They believe that in order for people to build the projects that will get the public using blockchain technology, you need to make it as easy and painless as possible for people to experiment and use the technology as possible.
