Abstract: Disclosed are systems and methods that utilize multiple single asset types and blockchain-based ledgers utilized by a custodian to issue a digital representation of assets held by the custodian. Trading entities place, with the custodian, respective assets that are represented on the ledgers. Genesis blocks on each blockchain-based ledger are signed by the exchange network which provides the initial trust and acts as a barricade against a rogue node from entering the network. Trading entities use the exchange network to agree on a price and enter into trades. The trades can include one asset type for another asset type. An atomic exchange is performed, and a trade is complete. Changes to token ownership are recorded on respective custodian ledgers automatically and redemption occurs upon request by a trading entity such that the ledger can be updated in actual currency and moved from the custodian to a trading entity account.
