The POA network attempts to build an open and public network based on the Ethernet protocol, using Proof of Authority. The main core idea of this project is to enable individuals to use the POA protocol to establish a faster and lower cost smart contract platform compared to the POW protocol. Another key solution is to build a network bridge between blockchains based on the rules of the Ethereum protocol, so that blockchains of different protocol types (such as POW and POA) have interactivity and connectivity.The POA project is the only one of 318 successful financing projects in 2017 that has developed a complete Codebase before financing, and released its own main network and blockchain browser while distributing tokens with ultra-high working efficiency and the fastest speed, realizing an independent public blockchain project for cross chain applications.At present, the cross chain concept of Cryptocurrency is as follows: Polk, Aion, Icon, Wanchain, Cosmos. These projects either remain in the conceptual stage or require a lengthy development cycle of 1-2 years. In this situation, POA achieved cross chain ICO applications early on, taking a breakthrough step in the cross chain field....
