What is Ring Miner (Loopring)?

In the Loopring network, ring miners are a type of network mining participant that are responsible for filling orders before they're executed or canceled by using a process that circumvents traditional order books and the AMM mechanisms governing liquidity pools. Those who operate as ring miners receive a service fee in LRC tokens or split the margin on the order amount. This system ensures that miners receive fair compensation for their efforts while incentivizing them to get the best rate for traders since their margin is higher if the exchange rate is. Ring miners also reduce arbitrage opportunities because the underlying protocol should always have the best trade value.
