Aventus is a layer-2 blockchain protocol that brings scalability, lower costs, and speed to Ethereum transactions. Ethereum has scalability issues that make it a victim of its own success. As the blockchain network of choice for most businesses, its maximum transaction throughput is wildly insufficient in meeting demand. The economics of supply and demand have thus skyrocketed transaction fees making them prohibitively expensive. The Aventus Network (AvN) solves that problem by letting businesses build on top of the Ethereum network with Aventus’ second-layer protocol. With the AvN, applications can easily work with any other promising blockchain tech, cross-chain, by plugging into the Polkadot ecosystem, building on Substrate.
