ETHD is a decentralized open platform built on the Ethereum network, aiming to solve the performance bottleneck of the current public chain and become a new generation of blockchain application operating system. The core of ETHD's network is a uniquely designed open blockchain system, which was born to solve the problems of insufficient scalability and low efficiency that Ethereum has criticized. It has smart contracts, high-transaction applications, and distributed ledgers. and other functions. After listing the transaction, the project party is committed to building a mapping public chain and starting the pledge mining output reward ETHD. After the public chain is built, two to three side chain products will be uploaded synchronously, opening an ecological environment with ETHD as the core.
