The goal of DAEX is to provide a better infrastructure for the cryptocurrency trading industry by taking the reasonable parts of the mainstream securities trading industry and by taking advantages of new opportunities brought about by the distributed ledger technology. Specifically, trading and clearing will be separated into different entities. Current centralized exchanges will continue to provide trading service. But the clearing work will be handled over to a common clearing service which is based on the DAEX solution. But, different from current centralized clearing services, the DAEX clearing service is based on distributed ledger technology. The distributed ledger technology guarantees that trades are correctly and safely cleared and settled. By using distributed ledger technology, trader’s assets are kept in their own accounts on the blockchain. No one else can access traders’ assets without their permissions. This effectively removes trader’s asset risks in current centralized exchanges. The DAEX solution will be an open sourced clearing service based on a public blockchain. Its code is open for public inspection and supervision.
