ETF (Ether Communication Chain) is a global universal communication chain issued by the ETF Ecosystem Community Foundation, referred to as ETF. ETFs do not conduct ICOs and do not publicly raise funds from investors. The ETF was initially issued based on the Ethereum ERC20 protocol, and will be transferred to the self-developed public chain in the future. Building ETF into an important part of the ecosystem will be applied in the ETF platform ecosystem and various ecological chain projects invested by ETF in the future. Sharing and transparency are the core concepts of the blockchain. ETF will launch a platform ecosystem sharing plan to allow every user to participate in the construction and development of the platform and jointly build the ETF blockchain ecosystem. Holders enjoy the rights and interests of the entire ETF ecosystem and are rewarded, as well as the scarcity enhancement brought about by the continuous repurchase and destruction of the ETF ecosystem community.
