     TECHNICAL FIELD 
     Various embodiments of the present disclosure generally relate to trading. More specifically, various embodiments of the present disclosure relate to systems and methods for trading digital transactional items such as assets, liabilities, commodities, and/or currencies using distributed and cryptographic (“crypto”) techniques. 
     BACKGROUND 
     Recent increasing adoption of crypto currencies (e.g., Bitcoin) worldwide creates challenges for existing trading systems. For example, market data and ownership data are stored differently. Additionally, existing trading systems use protocols for pre-trade communications and execution that are not compatible with trading systems that trade digital transactional items. 
     The present disclosure overcomes these and other limitations of existing trading systems, and provides other benefits as will become clearer to those skilled in the art from the following description.

     DETAILED DESCRIPTION 
     Various embodiments of the present disclosure generally relate to trading digital transactional items, more particularly digital assets, such as securities. More specifically, various embodiments of the present disclosure relate to systems and methods for trading digital securities using distributed and cryptographic techniques, and, in particular, a Crypto Integration Platform. The Crypto Integration Platform receives orders to trade digital transactional items such as digital assets, liabilities, commodities, and/or currencies (e.g., digital securities, digital interests in securities, crypto currencies) for other digital transactional times such as digital representations of funds (e.g., tokens, cash, cash equivalents such as crypto currencies) on a cryptographic (“crypto”) exchange (i.e., an exchange that trades digital transactional items) from broker-dealers and translates the orders into crypto orders. 
     The Crypto Integration Platform aggregates market information from the crypto exchanges and serves as a router to locate the best price in the crypto market for the digital asset or liability involved in the transaction. Prior to matching orders, the Crypto Integration Platform secures both the digital transactional items (i.e., the funds for a buy order and the digital assets or liabilities for a sell order) and cryptographically signs the transactions. Once a potential matching order has been located, the Crypto Integration Platform verifies that the funds and the digital assets/liabilities are available for trade (e.g., associated with addressed accounts owned by the buyer and the seller) and clears and settles the transaction instantaneously by associating the funds and digital assets or liabilities with corresponding addressed accounts. 
     Benefits of the Crypto Integration Platform include guaranteed settlement, transparency of ownership and easy money movement, and secure settlements. Cryptographically signing the transactions ensures authentication, authorization, and provenance. 
     The Crypto Integration Platform provides, among other things, an interface between legacy trading systems and crypto exchanges that trade digital transactional items. In doing so, the Crypto Integration Platform takes a protocol for trading and communication between broker-dealers, Alternative Trading Systems (“ATS”), and exchanges, and transforms the message so that the trade can be consummated using cryptographic techniques. For example, one protocol is the Financial Information eXchange protocol or “FIX” protocol. The Crypto Integration Platform allows broker-dealers to integrate the technology described herein on the backend of legacy trading systems, opening up legacy trading systems to crypto exchanges. Thus, the Crypto Integration Platform allows more companies to enjoy access to capital and more investors to enjoy access to shares of the participating companies. Messages in the FIX protocol are used in many examples in the present disclosure. However, the Crypto Integration Platform can receive and transform messages in protocols other than the FIX protocol to be consummated using cryptographic techniques. 
     The Crypto Integration Platform uses crypto ledgers or distributed ledgers (e.g., block chains) to verify ownership and availability of the digital transactional items being exchanged. The Crypto Integration Platform, or components of it, may be used by securities issuers to conduct initial public offerings and other SEC-registered public offerings of securities, and by the general public to trade those securities in secondary market transactions. 
     The digital transactional items traded on crypto exchanges may be transferred to other owners using cryptographic techniques such as public-key cryptography and bidirectional encryption, as well known in the art. Public-key cryptography requires a key pair, where the two keys are mathematically linked. One key is a public key that is freely shared among nodes in a peer-to-peer network. The other key is a private key that is not shared with the public. The public key is used to encrypt plaintext and to verify a digital signature. The private key is used to decrypt cipher text and to digitally sign transactions. Transaction messages may be digitally signed by the sender&#39;s private key to authenticate the sender&#39;s identity. Then, the sender&#39;s digitally-signed transaction message may be decrypted using the sender&#39;s public key to verify that the sender originated the transaction. 
     Ownership of the digital transactional items may be based on ownership entries in distributed ledgers that are maintained by network nodes. The distributed ledgers (e.g., block chain for Bitcoin) record entries for each change of ownership of each digital transactional item and may be mathematically linked to the key pairs. To sell a digital asset or digital liability, a transaction message (e.g., in packets or other data structures) may be broadcast to nodes on a peer-to-peer network. The transaction message can be signed by the seller&#39;s private key and may include information such as a history of the chain of title of the digital asset or digital liability, the number of shares or items being transferred and the purchaser&#39;s public key-based address. When a majority of the nodes in the network agree that the sender has the proper chain of title, ownership is changed to the purchaser and the ledger is updated to indicate the transaction. 
     Integrating a crypto trading system (i.e., a system that trades digital assets or liabilities on a crypto exchange) into a traditional trading system creates challenges that the present disclosure addresses. For example, this disclosure introduces a process in which orders to trade digital assets or liabilities are submitted via a legacy system. In another example, this disclosure introduces a process to ensure that a crypto trading order originally received into the legacy system is authorized by the same entity as the original order. Additionally, this disclosure introduces a system and method for matching cryptographic transactions based on non-shared private keys and shared public keys. 
     The techniques introduced here can be embodied as special-purpose hardware (e.g., circuitry), as programmable circuitry appropriately programmed with software and/or firmware, or as a combination of special-purpose and programmable circuitry. Hence, embodiments may include a machine-readable medium having stored thereon instructions that may be used to program a computer (or other electronic devices) to perform a process. The machine-readable medium may include, for example, floppy diskettes, optical disks, compact disc read-only memories (CD-ROMs), magneto-optical disks, read-only memories (ROMs), random access memories (RAMs), erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), magnetic or optical cards, flash memory, or other type of media/machine-readable medium suitable for storing electronic instructions. 
       FIG. 1  illustrates an example of a network-based operating environment  100  in which some embodiments of the present disclosure may be used. As illustrated in  FIG. 1 , operating environment  100  includes applications  105 A- 105 N running on one or more computing devices  110 A- 110 M (such as a mobile device, a mobile phone, a tablet computer, a mobile media device, a mobile gaming device, a vehicle-based computer, a dedicated terminal, a public terminal, desktop or laptop computer, a kiosk, etc.). In some embodiments, applications  105 A- 105 N are used for carrying out operations such as generating orders, and checking account balances may be stored on the computing devices or may be stored remotely. These computing devices can include mechanisms for receiving and sending traffic by connecting through network  120  to Crypto Integration Platform  125  and broker-dealer(s)  115 . 
     Computing devices  110 A- 110 M are configured to communicate via network  120  with broker-dealer(s)  115  and Crypto Integration Platform  125 . In some embodiments, computing devices  110 A- 110 M can retrieve or submit information to Crypto Integration Platform  125  and run one or more applications with customized content retrieved by Crypto Integration Platform  125  and broker-dealer  115 . For example, computing devices  110 A- 110 M each can execute a browser application or a customized client to enable interaction between the computing devices  110 A- 110 M and Crypto Integration Platform  125  and broker-dealer  115 . 
     Broker-dealer(s)  115  are entities (i.e., natural persons, companies, or other organizations) that engage in the business of trading assets (e.g., securities, mutual fund shares, etc.) for their own account or on behalf of their customers. When executing trade orders on behalf of a customer, the entity acts as a broker. When executing trades for its own account, the entity acts as a dealer. Broker-dealer(s)  115  may receive orders from computing devices  110 A- 110 M or create their own orders. Broker-dealer(s)  115  may communicate orders to Crypto Integration Platform  125  via network  120 . The orders sent by broker-dealer(s)  115  may use the FIX protocol or other protocols and/or formats. 
     Crypto Integration Platform  125  can run on one or more servers and can be used to trade digital transactional items. In some embodiments, as illustrated, Crypto Integration Platform  125  includes a Crypto Adapter  130 , Crypto Bridge  135 , and Crypto Matching Component  140 . 
     Crypto Adapter  130  receives orders for trading digital transactional items from broker-dealer(s)  115  and, in some embodiments, directly from computing devices  110 A- 110 M. The orders are received by Crypto Adapter  130  in a conventional protocol/format commonly used by broker-dealer(s)  115  (e.g., FIX messages). Crypto Adapter  130  translates the orders into cryptographic transactions, verifies ownership of assets and funds in the orders using Crypto Ledger(s)  160 , cryptographically signs the cryptographic transactions to transfer assets and funds, and verifies that the cryptographic transaction is authorized by the same customer authorizing the FIX order. Crypto Bridge  135  aggregates and provides market data from Crypto Exchange(s)  155  to broker-dealer(s)  115 . Crypto Matching Component  140  matches buy and sell orders of the digital assets, executes the orders, and returns execution reports to broker-dealer(s)  115  in the existing broker-dealer(s)&#39;s format. Thus, the Crypto Integration Platform  125  seamlessly integrates into the operations of current broker-dealer(s)  115  to allow broker-dealer(s)  115  to trade securities on Crypto Exchange(s)  155  without knowledge of public or private keys, ledgers, and block chains. 
     Crypto Integration Platform  125  is communicably coupled with one or more ATS  150 , Crypto Exchange(s)  155 , and Crypto Ledger(s)  160  through network  145 . 
     Network  120  and network  145  can be the same network or can be separate networks and can be any combination of local area and/or wide area networks, using wired and/or wireless communication systems. Either network  120  or network  145  could be or could use any or more of the following protocols/technologies: Ethernet, IEEE 802.11 or Wi-Fi, worldwide interoperability for microwave access (WiMAX), cellular telecommunication (e.g., 3G, 4G, 5G), CDMA, cable, digital subscriber line (DSL), etc. Similarly, the networking protocols used on network  120  and network  145  may include multiprotocol label switching (MPLS), transmission control protocol/Internet protocol (TCP/IP), User Datagram Protocol (UDP), hypertext transport protocol (HTTP), simple mail transfer protocol (SMTP) and file transfer protocol (FTP). Data exchanged over network  120  and network  145  may be represented using technologies, languages and/or formats including hypertext markup language (HTML) or extensible markup language (XML). In addition, all or some links can be encrypted using conventional encryption technologies such as secure sockets layer (SSL), transport layer security (TLS), and Internet Protocol security (Ipsec). 
     ATS(s)  150  are non-exchange trading systems that find counterparties for transactions by matching buyers and sellers. ATS(s)  150  are an alternative to traditional stock exchanges. Examples of ATS(s)  150  include electronic communication networks (ECNs), crossing networks, dark pools, and call markets. ATS(s)  150  receive digitally signed FIX orders from Crypto Integration Platform  125 , find potential buy/sell order matches to trade digital assets, and contain a state of the order book which records the state of the orders. 
     Crypto Exchanges(s)  155  are exchanges that trade digital transactional items such as digital shares of stock, bonds, or currency. Digital shares of stock may be of the same class of stock as securities listed on traditional exchanges. Ownership of the digital transactional items in Crypto Exchange(s)  155  can be recorded on one or more distributed ledgers such as Crypto Ledger(s)  160 . Crypto Exchange(s)  155  receive digitally signed crypto transactions (e.g., orders, cancellations) from Crypto Integration Platform  125 . 
     Crypto Ledger(s)  160  record economic transactions such as the sale of digital assets or liabilities in exchange for funds. Crypto Ledger(s)  160  vary per unit. For example, Bitcoin uses a distributed public ledger called the block chain. When Crypto Ledger(s)  160  receives a transaction signed with the proper key from Crypto Integration Platform  125  and the transaction is verified by network nodes, the Crypto Ledger(s)  160  moves the digital transactional items to the proper address (e.g., the proper wallet) by recording the transaction (e.g., adding a block chain into the ledger). 
     Various data stores can be used to manage storage and access to digital securities, user information, and other data. The data stores may be distributed data stores such as Crypto Ledger(s)  160 . The data stores may be a data repository of a set of integrated objects that are modeled using classes defined in database schemas. Data stores may further include flat files that can store data. Crypto Integration Platform  125  and/or other servers may collect and/or access data from the data stores. 
       FIG. 2  illustrates a set of components within Crypto Integration Platform  125  according to one or more embodiments of the present disclosure. According to the embodiments shown in  FIG. 2 , Crypto Integration Platform can include memory  205 , one or more processor(s)  210 , Crypto Adapter  215 , Crypto Bridge  220 , and Crypto Matching Component  225 . Other embodiments may include some, all, or none of these modules and components along with other modules, applications, and/or components. Still yet, some embodiments may incorporate two or more of these modules and components into a single module and/or associate a portion of the functionality of one or more of these modules with a different module. For example, in one embodiment, Crypto Bridge  220  and Crypto Matching Component  225  can be combined into a single component. 
     Memory  205  can be any device, mechanism, or populated data structure used for storing information. In accordance with some embodiments of the present disclosure, memory  205  can be or include, for example, any type of volatile memory, nonvolatile memory, and dynamic memory. For example, memory  205  can be random access memory, memory storage devices, optical memory devices, magnetic media, floppy disks, magnetic tapes, hard drives, erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), compact discs, DVDs, and/or the like. In accordance with some embodiments, memory  205  may include one or more disk drives, flash drives, one or more databases, one or more tables, one or more files, local cache memories, processor cache memories, relational databases, flat databases, and/or the like. In addition, those of ordinary skill in the art will appreciate many additional devices and techniques for storing information which can be used as memory  205 . 
     Memory  205  may be used to store instructions for running one or more applications or modules on processor(s)  210 . For example, memory  205  could be used in one or more embodiments to house all or some of the instructions needed to execute the functionality of Crypto Adapter  215 , Crypto Bridge  220 , and Crypto Matching Component  225 . 
     Crypto Adapter 
     Crypto Adapter  215  serves as the interface between broker-dealers and crypto exchanges. Crypto Adapter  215  communicates with Crypto Bridge  220  to provide market data to the broker-dealers from the crypto exchanges. Crypto Adapter  215  also integrates new customers by storing a customer identifier provided by the broker-dealer and generating two separate key pairs. Each key pair has one private key and one public key. The two parts of the key pair are mathematically linked. The public key of a key pair may be published without compromising security, whereas the private key of a key pair must not be revealed to anyone not authorized to read messages or perform digital signatures. 
     The two key pairs are used to create two addressed accounts associated with the customer identifier. The addressed accounts may be referred to as “wallets.” Both wallets represent digital accounts. The first wallet, referred to at times, herein as the customer portfolio wallet, stores digital transactional items such as digital assets and liabilities (e.g., digital shares of stocks) and digital funds (e.g., digitized dollars, tokens, crypto currency). In some embodiments, the customer associated with the customer identifier owns the key pair for the wallet, but authorizes Crypto Adapter  215  to use the key pair to complete transactions on behalf of the customer. In other embodiments, Crypto Adapter  215  or a third party owns the customer portfolio wallet. The second wallet, referred to at times herein as the customer committed wallet, stores digital transactional times that the customer has placed in buy or sell orders that have not yet been completed (e.g., “committed” assets or funds). Crypto Adapter  215  either owns the keys for the customer committed wallet or is authorized to use the keys to the customer committed wallet. In some embodiments, a parent wallet may be created that includes many different customer portfolio wallet and customer committed wallet keys. The parent wallet may include keys for different public ledgers thereby providing one master account for a broker-dealer. 
     Crypto Adapter  215  can receive a request from a broker-dealer to obtain the balance of the wallets. Using the customer identifier, Crypto Adapter  215  can identify the correct customer portfolio wallet and customer committed wallet. Then, Crypto Adapter  215  can use the corresponding public key for the customer portfolio wallet and the customer committed wallet to obtain the balance for each wallet from one or more crypto ledgers. 
     Crypto Adapter  215  can receive a FIX order message (or similar message) that includes a buy, sell, or cancel order associated with a customer identifier from broker-dealers. If the order is a buy order, the FIX order message indicates that the broker-dealer has U.S. dollars (or other currency) for the transaction on deposit. Therefore, Crypto Adapter  215  issues a representation that funds from the customer are being held at the broker-dealer specifically to settle the trade. The representation can be a digital liability or IOU from the broker-dealer. Such digital representation may be stored in or associated with the customer portfolio wallet. In some embodiments, the funds could be sent via a crypto currency transaction from a wallet (i.e., addressed account) of a broker-dealer to the customer portfolio wallet. 
     Crypto Adapter  215  creates a crypto committed transaction (i.e., a transaction involving buying or selling digital assets or liabilities on the crypto exchange) for the buy order which includes information for the transfer of digital liabilities from a source account (i.e., customer portfolio wallet) to a destination account (i.e., customer committed wallet) and signs the crypto committed transaction with the private key of the customer portfolio wallet. The crypto committed transaction may include the USD token, the customer identifier, and/or the public key of the committed wallet. After the transaction is signed by the Crypto Adapter  215  and verified by the network nodes, the transfer of the USD token to the customer committed wallet is completed and the transaction is updated in the crypto ledger. 
     In addition to creating a crypto committed transaction, Crypto Adapter  215  creates a FIX order transaction. To create the FIX order transaction, Crypto Adapter  215  takes a non-crypto FIX order, maps the customer to a set of wallets and keys using the customer identifier, and creates and signs the FIX transaction with the customer portfolio wallet private key. The FIX transaction may be enriched with the output of the crypto order transaction, specifically a transaction identifier or hash of the crypto transaction order. The FIX order transaction can include a message type (e.g., buy, sell), order identifier, funding transaction hash, return account, and a public key. Before sending the FIX order transaction to the ATS, the signature authorizing the FIX order transaction is compared to the signature authorizing the crypto committed transaction. If the signatures match, then the order can be sent to the ATS. Thus, signing the FIX order transaction and the crypto order transaction with the same private key allows Crypto Adapter  215  to mathematically verify that the order originated from the same entity. This prevents attackers from monitoring the public ledger and trying to create fraudulent orders which appear to be backed by a committed order. 
     Crypto Adapter  215  routes the signed FIX order transaction to an ATS to find a potentially matching sell order. Crypto Adapter  215  routes the signed crypto committed transaction to Crypto Bridge  220 , which eventually routes the signed crypto committed transaction to a crypto exchange to find a matching sell order. As discussed below, Crypto Bridge  220  compares the signatures on the FIX order transaction and the crypto committed transaction. Public-key cryptography can be used to determine whether the signatures match. Crypto Adapter  215  also creates and delivers execution reports to the broker-dealer informing the broker-dealer that the buy order is pending. Crypto Adapter  215  also receives execution reports from the Crypto Matching Component  225  that Crypto Adapter  215  forwards to broker dealers. 
     Crypto Adapter  215  processes sell orders in much the same manner as buy orders except that Crypto Adapter  215  does not issue a USD token or other digital representation because the digital security is backed by the organization that issued it. 
     Crypto Adapter  215  receives cancel orders from broker-dealers. Crypto Adapter  215  receives a cancel order request and maps customer identifiers to customer committed wallets. After obtaining wallet balances from one or more crypto ledgers, Crypto Adapter creates a FIX cancel transaction and signs the transaction with the customer committed wallet private key. After Crypto Adapter  215  verifies that the FIX cancel transaction was signed by the same private key as the original crypto order transaction (e.g., using public-key cryptography), a crypto cancel transaction order is created. Crypto Adapter  215  signs the crypto cancel transaction with the customer committed wallet private key to effectuate the transfer of the funds or assets to the customer portfolio wallet by the crypto ledger. Signing the crypto cancel transaction ensures that the entity originating the cancel order is authorized to do so. This prevents attackers from surreptitiously removing orders to front run the transactions. 
     Crypto Bridge 
     Crypto Bridge  220  receives requests for market data on the crypto exchanges from Crypto Adapter  215 . Crypto Bridge  220  aggregates information from the crypto exchanges and serves as a router to locate the best price in the crypto market for the security involved in the transaction. The Crypto Bridge can aggregate the data by monitoring crypto ledgers to generate a current snapshot of the order book by subscribing to order information which is visible on the public ledger. The crypto exchanges may have different distributed ledgers. Crypto Bridge  220  further provides a single interface for broker-dealers by normalizing different distributed ledgers. For example, various distributed ledgers may be used and these distributed ledgers may have different application programming interfaces with different associated keys. Crypto Bridge  220  accesses the data from all the distributed ledgers and provides the data in one standard format. Thus, broker-dealers enjoy access to a crypto exchange without dealing with disparate wallet and key generation, committed transactions, retrieval of balances, among other things. 
     Crypto Matching Component 
     Crypto Matching Component  225  receives a match request from an ATS that identifies two committed orders (i.e., orders in which the digital transactional items have been transferred to the customer committed wallets) that are potentially a match. The match request includes the order identifiers for each committed transaction. Crypto Matching Component  225  maps order identifiers to the committed customer portfolio wallet for each order. Crypto Matching Component  225  obtains the balances of the customer committed wallets from the crypto ledger to ensure that from the selling side, the asset or liability is available and committed for the transaction, and from the buying side, that the funds are available and committed for the transaction. Crypto Matching Component matches the request response and includes the counterparty hashes or signatures from the customer portfolio wallets. Crypto Matching Component then settles and clears the transactions by deducting from the customer committed wallets and crediting the customer portfolio wallets for each party using the counterparty hashes or signatures from the customer portfolio wallets. 
       FIG. 3  is a diagram illustrating interaction of components used in trading digital assets. As shown in  FIG. 3 , customers ( 302 ,  304 ,  306 ,  308 ,  310 ,  312 ,  314 ,  316 ) interface with broker-dealers ( 318 ,  320 ). The broker-dealers receive orders from the customers to trade non-digital assets or liabilities on traditional exchanges as well as orders to trade digital assets or liabilities on crypto exchanges ( 332 ,  334 ). If an order involves trading digital transactional items, the order is routed to the Crypto Adapter ( 322 ) in a standard format for broker-dealers such as FIX orders. Using cryptographic techniques, the Crypto Adapter ( 322 ) transfers the digital transactional items corresponding to the order from the customer portfolio wallet to the customer committed wallet, which creates a “signed crypto transaction.” The signed crypto transaction is sent to the Crypto Bridge ( 328 ). Then, the Crypto Adapter ( 322 ) creates and signs a FIX transaction order which is sent to one or more ATSs ( 324 ,  326 ). The Crypto Adapter ( 322 ) verifies that the FIX transaction and the crypto transaction were authorized by the same party by comparing cryptographic signatures. 
     Assuming that the signatures match, Crypto Matching Component ( 330 ) receives a potential match for the orders from one or the ATSs ( 324 ,  326 ) or one of the Crypto Exchanges ( 332 ,  334 ). In some embodiments, the orders can be sent to more than one ATS and/or more than one Crypto Exchanges. The Crypto Matching Component verifies that the digital transactional items are available and instantaneously clears and settles the transaction. 
       FIG. 4  is a diagram illustrating an architecture of a Crypto Integration Platform  125 . As shown, broker-dealers ( 402 ) communicate with the Crypto Integration Platform  125  ( 408 ,  410 ,  412 ) via one or more networks ( 404 ,  406 ). The Crypto Integration Platform  125  communicates with crypto ledgers ( 416 ,  418 ) via one or more networks ( 414 ). Once an order to purchase or sell digital transactional items, or to cancel an order, is received by broker-dealers ( 402 ), adapter ( 408 ) creates a transaction on the legacy system that will be sent to an ATS and to a cryptographic exchange. Information including wallet keys, user information, and transactions are created and stored in databases ( 420 ,  422 ,  424 ) and on various distributed ledgers ( 416 ,  418 ). Assets are verified and moved into the customer committed wallets and the transactions are signed. Market data is gathered from distributed public ledgers such as the block chain. As shown with the multiple crypto ledgers ( 416 ,  418 ), the transaction is agnostic to the type of distributed ledger used to record the transaction. Bridge ( 410 ) normalizes the market data from the various cryptographic exchanges. Orders are matched in the matching component ( 412 ). 
       FIG. 5  is a flowchart illustrating a process  500  of trading digital assets from the perspective of a broker-dealer, using the Crypto Integration Platform. Receiving operation  502  receives an order from a customer at a computing device of a broker-dealer. The order may include an order to buy or sell one or more digital transactional items, or an order to cancel a pre-existing order. Upon receiving the order, the broker-dealer may create an order message in the FIX protocol (or other protocol) and send the order to the Crypto Integration Platform in sending operation  504 . After the Crypto Integration Platform checks the customer account balances (i.e., balances of the customer portfolio wallet and the customer committed wallet) and commits the digital funds or asset to the order, the broker-dealer receives execution reports with the status of the order (e.g., order pending, order executed, order canceled) in receiving operation  506 . The execution reports are provided in the same format that the broker-dealer receives from trades that take place on typical exchanges. 
       FIG. 6  is a flowchart illustrating a process  600  of trading digital transactional items from the perspective of the Crypto Integration Platform. In some embodiments, the operations performed in  FIG. 6  can be performed by the Crypto Adapter. In some embodiments, fewer or more operations may be performed or the operations may be performed in different orders. 
     Creating operation  602  creates a first addressed account (e.g., customer portfolio wallet) and a second addressed account (e.g., customer committed wallet) for a customer. The first and second addressed accounts can each have an associated key pair and may both be associated with a customer identifier. Various digital transactional items owned by the customer can be associated with the first and second addressed accounts. Receiving operation  604  receives an order to buy or sell digital transactional items such as a digital security. 
     Signing operation  606  can electronically sign a first transaction to transfer the digital transactional items from the first addressed account to the second addressed account with a private key associated with the first addressed account. Signing operation  606  can also electronically sign a second transaction with the private key of the first addressed account, a second transaction. Verifying operation  608  verifies that the first transaction was signed with the same private key as the second transaction. Authorizing operation  610  authorizes placement of the digital transactional items on a cryptographic exchange after verifying that the first transaction was signed with the same private key as the second transaction. 
       FIG. 7  is a flowchart illustrating a process  700  of trading digital transactional items from the perspective of the Crypto Integration Platform. In some embodiments, the operations performed in  FIG. 7  can be performed by the Crypto Matching Component. In some embodiments, fewer or more operations may be performed or the operations may be performed in different orders. 
     Receiving operation  702  receives a request to match a buy transaction with a sell transaction. The buy transaction can include a buy order to purchase digital transactional items for a specified amount (e.g., an amount corresponding to a value of the digital transactional items) and the sell transaction can include a sell order to sell the digital transactional items for an amount. The customer purchasing the digital transactional items can have two addressed accounts: a first customer portfolio wallet and a first customer committed wallet. The customer selling the digital transactional items can also have two addressed accounts: a second customer portfolio wallet and a second customer committed wallet. 
     The buy transaction can have an associated first signature that corresponds to the first addressed account (e.g., first customer portfolio wallet) that identifies the buy order. The sell transaction can have an associated second signature corresponding to a second addressed account (e.g., second customer portfolio wallet) that identifies the sell order. The amount of funds can be associated with a third addressed account associated with the first customer (e.g., first customer committed wallet) and the one or more digital transactional items can be associated with a fourth addressed account associated with the second customer (e.g., second customer committed wallet). 
     Mapping operation  704  maps the buy transaction to the third addressed account (e.g., first customer committed wallet) and the sell transaction to a fourth addressed account (e.g., second customer committed wallet); 
     Sending operation  706  sends a match request response to the cryptographic exchange. The match request can include the first signature and the second signature to commit the buy transaction. Transferring operation  708  transfers the digital transactional items to the first addressed account (e.g., first customer portfolio wallet). Transferring operation  710  transfers the amount to the second addressed account (e.g., second customer portfolio wallet) to settle and clear the buy transaction and the sell transaction. 
     Creating a Customer 
       FIG. 8  illustrates a process  800  of integrating a new customer into the Crypto Integration Platform to allow the customer to trade digital securities. When a user signs up ( 802 ), the broker-dealer, via a user interface (“UI”), collects customer data such as name, bank account information, and securities owned by the customer ( 804 ). The customer data may be verified in a Know Your Customer (“KYC”) process (or other process) ( 806 ) that receives data from the customer ( 808 ) and verifies the identity of the customer ( 810 ). The KYC process may be completed by an outside vendor or by the broker-dealer. If the identity of the customer is verified, the broker-dealer creates the customer in the broker-dealer&#39;s system ( 812 ). The broker-dealer may assign a customer identifier such as a customer identification number or other identifier to the customer. 
     Once the broker-dealer assigns the customer identifier to the customer, the customer identifier and customer data can be sent to the Crypto Adapter where the customer identifier and the customer data are stored in one or more databases ( 814 ). The Crypto Adapter can generate a key pair (e.g., a public key and a private key pair) for the customer ( 816 ) and create a customer portfolio wallet associated with the key pair and the customer identifier ( 816 ). The customer portfolio wallet can hold (i.e., be associated with) any digital transactional item such as funds (e.g., digital currency or a representation of currency) and digital assets or liabilities (e.g., digital shares of stock) owned by the customer. 
     Additionally, a second set of key pairs and a second digital wallet associated with the second set of key pairs and the customer identifier is created ( 818 ). The customer committed wallet may be used to secure digital transactional items committed in future orders, akin to an escrow account. Balances of the customer portfolio wallet and the customer committed wallet are recorded in distributed ledgers and can be accessed using the key pairs. In some embodiments, a third party may be commissioned to create the customer portfolio wallet and the customer committed wallet and to generate the corresponding key pairs. Once the customer portfolio wallet and customer committed wallet are created, the Crypto Adapter indicates to the broker-dealer that the customer is successfully created ( 820 ). The broker-dealer can receive the indication of successful creation of the customer ( 822 ). 
     Creating an Order 
       FIG. 9  illustrates a process  900  of creating an order to trade digital securities. The customer may login to the broker-dealer via a user interface (“UI”). After the customer logs in ( 902 ), broker-dealer may request Crypto Level 1 data (i.e., market data for securities trading on cryptographic exchanges such as the last bid and ask price for one or more securities) ( 904 ). This type of data can be used by traders to make buy, bid, and ask decisions for future trades. The request for the Crypto Level 1 data may be routed to the Crypto Bridge ( 906 ), which aggregates the data from one or more cryptographic exchanges. The Crypto Bridge retrieves the Crypto Level 1 data from the cryptographic exchanges ( 908 ,  910 ) and normalizes the data to produce the Crypto Level 1 data in a format used by existing systems of broker-dealers ( 912 ). In some embodiments, the broker-dealer requests additional data such as Crypto Level 2 data, which provides additional market data such as a history of the orders that have occurred over a period of time. The Crypto Bridge publishes, sends or otherwise makes the Crypto Level 1 data available to the interface of the broker-dealer ( 914 ). 
     The broker-dealer may request the balance of the assets (i.e., securities and digital funds) of the customer portfolio wallet and the customer committed wallet ( 916 ). The Crypto Adapter then uses the customer identifier sent by the broker-dealer to map the customer identifier to the customer portfolio wallet and the customer committed wallet ( 918 ). The customer portfolio wallet data and the customer committed wallet data are recorded with distributed crypto ledgers as opposed to a database owned by an exchange in typical trading systems today (e.g., New York Stock Exchange owns its trading data) ( 918 ). Therefore, to provide the wallet data to the broker-dealers, the Crypto Adapter gathers the wallet data from crypto ledgers. 
     To determine the balance of the customer and/or customer committed wallets, distributed ledgers are searched using the key pairs for the customer portfolio and/or customer committed wallets, respectively ( 920 ,  922 ). Once the balance is determined ( 924 ), the Crypto Adapter then provides the balance, including digital funds and digital assets, of both the customer portfolio wallet, which includes any settled balances, and the customer committed wallet to the user interface of the broker-dealer ( 926 ). The broker-dealer can display the balances associated with the customer portfolio wallet and/or the customer committed wallet ( 928 ) and may then receive a buy or sell order from the customer ( 930 ). The broker-dealer can determine whether the order is a buy order ( 930 ,  932 ) or a sell order ( 930 ,  934 ). 
     Processing a Buy Order 
       FIG. 10  illustrates a process  1000  of receiving and processing an order to purchase digital assets, liabilities, or other digital transactional items. The broker-dealer receives a buy order ( 1002 ) and determines based on the balance of the customer portfolio wallet, whether the customer has the buying power to make the purchase. Assuming the customer has the buying power to make the purchase; the broker-dealer confirms the order with the customer ( 1004 ) and places a hold on the cash or cash-equivalent that the broker-dealer has on deposit for the customer ( 1006 ). Next, the broker-dealer creates an order message using legacy trading protocols for pre-trade communications and trade execution, such as a FIX order message or equivalent order message ( 1008 ). For purposes of this example, a FIX order message will be used. 
     When the Crypto Adapter receives the FIX order message, the Crypto Adapter maps the customer identifier to both the customer portfolio wallet and the customer committed wallet ( 1010 ). Next, the Crypto Adapter creates a digital representation of the funds such as a USD token, which represents that cash from the customer is being held at the broker-dealer specifically to settle the trade (i.e., a digital liability or IOU from the broker-dealer generally in the amount of the quantity multiplied by the price of the asset) ( 1012 ). The Crypto Adapter issues the token to the customer portfolio wallet on behalf of the broker-dealer, which is recorded to the distributed ledger ( 1014 ,  1016 ). 
     Thereafter, the Crypto Adapter retrieves the customer portfolio wallet balance, which now includes the USD token, and the customer committed wallet balance from the crypto ledger ( 1018 ). The crypto ledger looks up the balances and provides the balances to the Crypto Adapter ( 1020 ,  1022 ). The Crypto Adapter determines whether the balance for the order is available ( 1024 ). If the balance is available, the Crypto Adapter creates and signs a crypto commitment transaction with the customer&#39;s private key for the customer portfolio wallet to transfer the USD token in the customer committed wallet ( 1026 ). The crypto committed transaction includes information such as a record of which address was used to send the USD token to the customer portfolio wallet, the amount of the USD token, and the address of the customer committed wallet. After receiving the signed crypto committed transaction and verifying it, the crypto ledger moves the USD token into the customer committed wallet by recording the transaction ( 1028 ) and the recordation is provided to the Crypto Adapter ( 1030 ). The USD token remains in the committed wallet pending either the settlement or cancellation of the transaction. 
     Once the USD token is moved from the customer portfolio wallet to the customer committed wallet ( 1032 ), the Crypto Adapter creates a FIX order transaction (which will eventually be sent to the ATS) and signs the FIX order transaction using the private key for the customer portfolio wallet ( 1034 ). The Crypto Adapter compares the signature from the crypto committed transaction with the signature from the FIX order transaction and determines whether the signatures match ( 1036 ). The Crypto Adapter may use asymmetric public key cryptography to determine whether the signatures match. 
     By verifying that the FIX order transaction was signed by the same party who signed the crypto committed transaction, the Crypto Integration Platform can provide certainty that the FIX order transaction is associated with the crypto committed transaction and therefore that the digital funds are available for the transaction. Additionally, the committed order is public information, so the public can see that the order has a committed balance. 
     If the signature from the committed transaction matches the signature from the FIX order transaction, the ATS and/or the cryptographic exchange places the order ( 1038 ) and creates an execution report ( 1040 ), which includes an order identifier. The Crypto Adapter maps the order identifier to the crypto committed transaction hash ( 1042 ). Next, assuming the order is placed successfully ( 1044 ), the Crypto Adapter creates an execution report indicating that the order is pending and issues the execution report to the broker-dealer ( 1046 ). The broker-deal can update its system to reflect that the order is successfully pending ( 1048 ). As illustrated, the Crypto Integration Platform allows a broker-dealer to trade on a cryptographic exchange simply by sending a FIX order message. 
     Processing a Sell Order 
       FIG. 11  illustrates a process  1100  of receiving and processing an order to sell digital assets, digital liabilities, or other digital transactional items on a cryptographic exchange. The process for the order to sell is similar to the process for the order to purchase assets, with one exception: there is no need to create a digital liability because the asset is backed by a corporate network. 
     The broker-dealer receives a sell order ( 1102 ) and determines based on the balance of the customer portfolio wallet provided by the Crypto Adapter whether the customer owns the asset to sell. Assuming the customer owns the asset to sell, the broker-dealer confirms the order with the customer ( 1104 ). Next, the broker-dealer creates a FIX order message or equivalent order message for pre-trade communications and trade execution ( 1106 ). For purposes of this example, a FIX order message will be used. 
     When the Crypto Adapter receives the FIX order message, the Crypto Adapter maps the customer identifier to the customer portfolio wallet and the customer committed wallet ( 1108 ). Next, the Crypto Adapter gathers the customer portfolio wallet balance and the customer committed wallet balance from the crypto ledger ( 1110 ,  1112 ,  1114 ). Assuming the digital assets or liabilities for sale are associated with the customer portfolio wallet ( 1116 ), the Crypto Adapter creates a crypto committed transaction and signs the crypto committed transaction using the private key for the customer portfolio wallet ( 1118 ). The crypto committed transaction may include a record of which address was used to send the digital assets to the customer portfolio wallet, an amount of the assets being committed to the trade, and the address of the customer committed wallet. After the signed crypto committed transaction is received and verified, the crypto ledger moves the asset into the customer committed wallet ( 1120 ) and creates a transaction response ( 1122 ). The asset remains in the customer committed wallet pending either the settlement or cancellation of the transaction. 
     Once the asset is moved from the customer portfolio wallet to the customer committed wallet successfully ( 1124 ), the Crypto Adapter creates a FIX order transaction and signs the FIX order transaction using the private key for the customer committed wallet ( 1126 ). The Crypto Adapter compares the signature from the committed transaction with the signature from the FIX order transaction and determines whether the signatures match ( 1128 ). As discussed above, asymmetric public key cryptography can be used to ensure that the signatures match. 
     By verifying that the FIX order transaction was signed by the same party as the crypto committed transaction, the Crypto Integration Platform can provide certainty that the FIX order transaction is associated with the committed transaction and therefore that the asset is available for the transaction. 
     If the signature from the committed transaction matches the signature from the FIX order transaction, the cryptographic exchange places the order ( 1130 ) and creates an execution report ( 1132 ), which includes an order identifier. The Crypto Adapter maps the order identifier to the crypto commitment transaction hash ( 1134 ). Next, assuming success ( 1136 ), the Crypto Adapter creates an execution report indicating that the order is pending and issues the execution report to the broker-dealer ( 1138 ). The broker-dealer can update its system to indicate that the order is successfully pending ( 1140 ). 
     Processing a Cancel Order 
       FIG. 12  illustrates a process  1200  of canceling a transaction to sell or purchase digital transactional items. If the order to cancel is successful, the digital transactional items (e.g., assets or digital funds) in a customer committed wallet pending a sale or purchase are moved back to the customer portfolio wallet If the digital transactional items have not yet been moved to the customer committed wallet, the cancel order ensures that the digital transactional items will not be moved to the customer committed wallet. The Crypto Integration Platform allows for cancellation of an order by showing that the cancellation is being ordered by the same entity that signed the original FIX transaction. 
     The broker-dealer receives a request to cancel an order ( 1202 ) and sends the request, including the customer identifier, to the Crypto Adapter ( 1204 ). When the Crypto Adapter receives the request to cancel the order, the Crypto Adapter maps the customer identifier to the customer portfolio wallet and the customer committed wallet ( 1206 ). Next, the Crypto Adapter checks the customer portfolio wallet balance and the customer committed wallet balance by querying the crypto ledger ( 1208 ,  1210 ). The crypto ledger looks up the customer&#39;s wallet balances ( 1210 ) and provides a response to the Crypto Adapter ( 1212 ). 
     Then, the Crypto Adapter determines whether the contents of the cancel order are in the customer committed wallet (i.e., the assets to be sold or the digital currency to be used for a purchase) ( 1214 ). If the contents of the cancel order are not in the customer committed wallet (i.e., the order has already been part of a settlement process), the cancel order is not carried out. If the contents of the cancel order are in the customer committed wallet, the Crypto Adapter creates a FIX cancel transaction and signs the FIX cancel transaction with the private key used to sign the original order that transferred the digital funds or assets into the customer committed wallet (i.e., the private key for the customer portfolio wallet) ( 1216 ). The original order is identified by the order identifier that is returned by the crypto matching component and/or the crypto order transaction. 
     Next, the Crypto Adapter compares the signature from the crypto committed transaction associated with the order with the signature from the FIX cancel transaction and determines whether the signatures match ( 1218 ). If the signature from the crypto cancel transaction matches the signature from the FIX cancel transaction, the cryptographic exchange cancels the order and creates an execution report, which includes an order identifier ( 1220 ). The cryptographic exchange creates an execution report  1222  for the Crypto Adapter. The Crypto Adapter maps the order identifier to the crypto cancel transaction hash ( 1224 ). Next, assuming a successful cancel of the order on the cryptographic exchange ( 1226 ), the Crypto Adapter creates and signs a crypto cancel transaction with the private key used to sign the cancel order and the order that transferred the digital funds or assets into the customer committed wallet (i.e., the private key for the customer committed wallet) ( 1228 ). The crypto ledger moves the digital funds or asset from the customer committed wallet into the customer portfolio wallet ( 1230 ) and creates a transaction response ( 1232 ). Assuming success ( 1234 ), the Crypto Adapter then creates an execution report indicating that the order is canceled and issues the execution report to the broker-dealer ( 1236 ). The broker-dealer then updates its system with the success cancellation of the order ( 1238 ). 
     Matching Orders 
       FIG. 13  illustrates a process  1300  of settling and clearing transactions for the purchase or sale of digital assets. The ATS identifies a potential match between a committed buy order and a committed sell order ( 1302 ) and sends a match request to the Crypto Matching Component to verify that the potential match is truly a match (i.e., that the wallet balances associated with each order identifiers are available) ( 1304 ). 
     The Crypto Matching Component receives the match request ( 1306 ), maps the order identifiers to the respective committed wallets ( 1308 ), and queries the crypto ledger for the customer committed wallet balances associated with both the buy order and the sell order ( 1310 ). The Crypto Ledger retrieves the balances ( 1312 ), creates a balance response ( 1314 ), and provides the balance response to the Crypto Matching Component ( 1316 ). The Crypto Matching Component verifies that the balances are available ( 1318 ). Assuming the corresponding buy and sell balances are present in the customer committed wallets; the Crypto Matching Component creates a match request to match the orders ( 1320 ). The match request includes the signature for the counterparty&#39;s customer portfolio wallet and/or counterparty hash for each order which identifies the original order and is publicly distributed on the ledger ( 1320 ). For example, the hash for the sell order is the identifier created when moving the asset from the customer portfolio wallet into the customer committed wallet. Similarly, the hash for the buy order is the identifier created during the transaction that moved the USD token into a committed state. 
     Once the cryptographic exchange receives the match request response indicating a match, the cryptographic exchange matches the transaction, commits the matched transaction ( 1322 ) by recording the exchange of assets/funds to the respective counterparty&#39;s customer portfolio wallets and creates the order execution ( 1330 ), which is routed to the Crypto Bridge and communicated to the broker dealer. Simultaneously or nearly simultaneously, the Crypto Matching Component settles and clears transactions using the counterparty hash ( 1324 ). The settlement and clearing of the transactions includes deducting the digital funds or assets from the purchasing or selling customer&#39;s committed wallet, respectively ( 1326 ), and crediting the purchasing and selling customer portfolio wallets with assets and digital funds, respectively ( 1328 ). The cryptographic exchange routes the order execution to the Crypto Bridge ( 1332 ), which routes the results of successful transaction to the broker-dealer ( 1334 ).

     Brief definitions of terms, abbreviations, and phrases used throughout this application are given below. 
     The terms “connected” or “coupled” and related terms are used in an operational sense and are not necessarily limited to a direct physical connection or coupling. Thus, for example, two devices may be coupled directly, or via one or more intermediary media or devices. As another example, devices may be coupled in such a way that information can be passed therebetween, while not sharing any physical connection with one another. Based on the disclosure provided herein, one of ordinary skill in the art will appreciate a variety of ways in which connection or coupling exists in accordance with the aforementioned definition. 
     The phrases “in some embodiments,” “according to some embodiments,” “in the embodiments shown,” “in other embodiments,” “embodiments,” and the like generally mean the particular feature, structure, or characteristic following the phrase is included in at least one embodiment of the present disclosure, and may be included in more than one embodiment of the present disclosure. In addition, such phrases do not necessarily refer to the same embodiments or different embodiments. 
     If the specification states a component or feature “may,” “can,” “could,” or “might” be included or have a characteristic, that particular component or feature is not required to be included or have the characteristic. 
     The term “responsive” includes completely or partially responsive. 
     The term “module” refers broadly to a software, hardware, or firmware (or any combination thereof) component. Modules are typically functional components that can generate useful data or other output using specified input(s). A module may or may not be self-contained. An application program (also called an “application”) may include one or more modules, or a module can include one or more application programs. 
     The term “network” generally refers to a group of interconnected devices capable of exchanging information. A network may be as few as several personal computers on a Local Area Network (LAN) or as large as the Internet, a worldwide network of computers. As used herein, “network” is intended to encompass any network capable of transmitting information from one entity to another. In some cases, a network may be comprised of multiple networks, even multiple heterogeneous networks, such as one or more border networks, voice networks, broadband networks, financial networks, service provider networks, Internet Service Provider (ISP) networks, and/or Public Switched Telephone Networks (PSTNs), interconnected via gateways operable to facilitate communications between and among the various networks.
