Let it be known to the entire world that on July 20th, 2016, at block 1,920,000, we as a community of sovereign individuals stood united by a common vision to continue the original Ethereum blockchain that is truly free from censorship, fraud or third party interference. In realizing that the blockchain represents absolute truth, we stand by it, supporting its immutability and its future. We do not make this declaration lightly, nor without forethought to the consequences of our actions.
