ExRelay is a network of Ethereum side chain settlement relay nodes based on Ethereum asset settlement. Under the premise of ensuring complete decentralization, high-frequency, low-cost, and efficient settlement of various asset trading businesses in the Ethereum world is carried out, and the global order pool is shared. The Exrelay network will introduce a large amount of complex matching and trading computing power from different businesses into the Exrelay network, and ensure complete decentralization of Ethereum assets for trading. Any DAPP in the Ethereum ecosystem can connect with the Exrelay network to solve the problem of multiple default business fund settlement through market-oriented actions, achieving instant suspension, instant cancellation, and instant transaction, Both no recharge and asset mapping are real assets, and most of the accounts received by Exrelay network still require confirmation from Ethereum World. EXrelay also adds a new confirmation mechanism for small transactions, using the lightning network mechanism for early confirmation and establishing a fund protection mechanism to protect any risk. Exrelay is an infrastructure technology that promotes the implementation of DAPP ecology, with all underlying designs, Both are the implementation of ensuring a low threshold for DAPP ecology, and the arrival of Ethereum 2.0 is full of infinite imagination for the future of Exrelay....
