AST or AirSwap Token is the membership token for AirSwap decentralized exchanges. People on AirSwap will be able to exchange decentralized ERC20 tokens for free. The AirSwap Token can securely transact without having to take liability to the third party (Exchanges) if someone accepts one cryptocurrency (or asset) with another. Transactions are handled between peers using MetaMask or any of the other Ethereum wallets.
Thanks to the Clearing Protocol, the transaction is free of charge. The protocol fulfills orders on the blockchain (or chain) through the Ethereum smart contract. Everything else is handled independently of the blockchain (or off-chain). Off-chain linking of merchants should do the AirSwap decentralized exchange faster than EtherDelta and even Plasma-based OmiseGO decentralized exchange than other decentralized exchanges connected to the blockchain for information dissemination and order fulfillment.
Linking investors in chains is not ideal. Because nodes in the network, like the Ethereum network, must agree on transactions in each block. The time to consensus on the Ethereum network is typically 15 seconds. Compared to traditional exchanges that transfer order information in microseconds, this is very slow.
In addition to the delay associated with the spread of order information on the chain, the ability of unethical parties to manipulate public information is possible. This phenomenon is called pre-running. Front run is not specific to cryptocurrency exchanges. However, it is a particular problem for decentralized exchanges that publish order information on the blockchain.
Fortunately, the Exchange Protocol eliminates front-run by miners and exchange operators. This is because the protocol does not publish order information on the public blockchain. Miners, mining what I do for financial gain is not sensitive information.
