ETHERCHAIN NETWORK aims to be a blockchain-based virtual currency platform, offering high availability, greater scalability, and the best stability. The first version of the ETHERCHAIN network was built using an ERC-20 token based on the Ethereum blockchain platform. For further development of the project, ETHERCHAIN will launch a DApp on the optimized blockchain platform, Rubidium Network. Ethereum facilitates the development of decentralized applications (DApps) driven on the blockchain through the use of the Ethereum Virtual Machine (EVM), making DApps fully compatible with traditional blockchain systems and capable of running on mobile devices. Ethereum combines a modified Bitcoin infrastructure with the EVM to provide an ecosystem where smart contracts can be utilized on a trusted blockchain, which is a form of private contract. The second version of ETHERCHAIN NETWORK is its mainnet that utilizes the EVM. ETHERCHAIN NETWORK has created a unique blockchain ecosystem that complies with EVM and Solidity standards and has undergone optimization for the DApp platform.
