We know that the number of blockchain projects that exist today is large, so it can be difficult for new projects to stand out from their competitors. Ethereum wants to challenge a variety of projects and create a faster, safer platform to develop intelligent contracts and distributed apps. One of these competitors is Aeternity. Aeternity is an open code platform, based on blockchain, computationally distributed and digital active based on P2P cryptographic technology. The platform is open to anyone, anywhere in the world. However, it's important to remember that Aeternity has no great ambitions to become a daily use coin. Aeternity's focus is more on data processing through the blockchain platform. When intelligent and DApps contracts are executed, Aeternity serves more as a means of parallel payment. Technically speaking, Aeternity could be one of Ethereum's greatest challenges. However, Ethereum has an extremely strong developer community that is capable of developing even more Ethereum using casper, sharding and plasma, in such a way that the current advantages of Aeternity will soon be no more advantages. However, Aeternity is a project that will attract attention if it's implemented successfully, especially with the launch of Mainnet.
