Ethereum Universe (ETU) is an international cross chain project initiated by blockchain developers from China, South Korea, Ukraine, and other countries. It uses globally leading cross chain 3.0 technology and innovative DPoS hybrid consensus mechanism to build a distributed financial infrastructure and connect global digital assets. The Ethereum universe has made bold technological innovations, pioneering a hybrid technology of "notary public mechanism+side chain", which enables efficient communication, while the notary public mechanism enables rapid value exchange. The Bitcoin network, Ethereum network, EOS network and other networks are connected through a third-party "connector" and "verifier". The distributed nodes act as connectors.In terms of consensus mechanism, the hybrid DPoS mechanism of miners, notaries, and guarantors was pioneered, and 48 universe nodes were deployed globally. Compared to PoW, DPoS does not rely on computing power, is energy-efficient and environmentally friendly, and significantly shortens the time for block confirmation; Compared to PoS, DPoS significantly reduces the number of nodes involved in verification and accounting, and can achieve consensus verification at the second level. The DPoS consensus mechanism itself has natural advantages, and the introduction of notaries and guarantors further enhances the stability and security of the system, which is a major breakthrough globally....
