The present invention relates to the field of product transport in a supply chain and more particularly to contracting for product transport within a supply chain.
A supply chain is a network between a company and its suppliers to produce and distribute a specific product, and the supply chain represents the steps it takes to get the product or service to the customer. Supply chain management is a crucial process because an optimized supply chain results in lower costs and a faster production cycle. Business logistics management refers to the production and distribution process within the company, while supply chain management includes suppliers, manufacturers, logistics and transportation companies and retailers that distribute the product to the end customer. Supply chains include every business that comes in contact with a particular product, including companies that assemble and deliver parts to the manufacturer.
Because the traditional supply chain involves many different actors utilizing many different disparate information systems, information sharing amongst the different actors can be challenging. Transparency into the state of affairs of a given transaction depends largely upon the willingness and diligence of each actor in the supply chain of the transaction to provide accurate and timely information to one another. In a single transaction, so much seems not so daunting, but in a supply chain ecosystem of hundreds if not thousands of transactions are ongoing at any given time and much of the resources available within the ecosystem—particularly in respect to transportation and logistics—remain dependent upon the state of multiple different transactions.
A supply chain information sharing system aims to provide some transparency into the state of affairs of different transactions in a corresponding supply chain. As part of the transparency, the supply chain information system ingests data from different actors in the supply chain, processes the ingested data in order to produce a result reflective of a state of the supply chain, and exposes the produced result to one or more of the actors. In a supply chain spanning a single jurisdiction amongst only a handful of actors, so much is not of tremendous consequence, but in a supply chain that spans different jurisdictional boundaries and involves many different actors with different policies regarding the privacy of data, maintaining both transparency of transactions in the supply chain while not running afoul of the data privacy policies of both the private actors in the supply chain and the public governmental interests in which the actors reside can be challenging.
Embodiments of the present invention address deficiencies of the art in respect to contracting for product transit in a supply chain and provide a novel and non-obvious method, system and computer program product for dynamic distributed smart contracting in the transport of product within a supply chain. In an embodiment of the invention, a smart contracting method includes receiving in an intermediate way station disposed on a route between an originator of shipment of an item and a destination indicated for the item, digital terms of shipment for the transport of the item, and a digital contract of transport of the item from the originator to the destination. The method also includes matching the terms of the shipment to pre-stored data indicating an ability of the way station to meet the terms of the shipment. Optionally, the digital terms may be verified by decrypting the digital contract with a public key of the originator and comparing the decrypted digital contract with a hash of the digital terms.
Thereafter, portions of the contract are identified that correspond to the way station and requirements of the identified portions are then matched to pre-stored rules indicating a willingness of the intermediate way station to agree to particular contract terms. Finally, a digital signature for the intermediate way station is affixed to the digital contract. In one aspect of the embodiment, the digital signature is a hash of the digital contract encrypted with a private key of the intermediate way station. On condition that the terms and requirements match, a next way station on the route selected, and transmission of the digital contract and terms of shipment directed to the selected next way station. To the extent that the pre-stored rules do not indicate a willingness of the intermediate way station to agree to particular terms, though, a message is transmitted to the originator rejecting the digital contract.
In yet another aspect of the embodiment, the next way station is selected by retrieving from a cache, different capabilities of a multiplicity of different way stations, comparing the different capabilities with the terms of the shipment, and selecting one of the multiplicity of the different way stations that has capabilities which match a greatest number of the terms of the shipment. In even yet another aspect of the embodiment, the next way station is selected by querying each of a multiplicity of different way stations for a list of corresponding capabilities, comparing each list received from the multiplicity of different way stations, and selecting one of the multiplicity of the different way stations that has capabilities which match a greatest number of the terms of the shipment. In even yet another aspect of the embodiment, the next way station is selected by retrieving from a cache, different capabilities of a multiplicity of different way stations, comparing the different capabilities with the terms of the shipment, filtering the multiplicity of different way stations to a subset, querying each way station in the subset for a list of updated capabilities, and selecting one of the way stations in the subset that has capabilities which match a greatest number of the terms of the shipment.
In another embodiment of the invention, a data processing system is configured for dynamic distributed smart contracting. The system includes a host computing platform of one or more computers, each with memory and at least one processor. The host computing platform includes a communicative coupling over computer communications network to different remote computing systems. Each of the different remote computing systems corresponds to a different way station on a route between an originator of a shipment of an item and a destination indicated for the item. Of note, the host computing platform corresponds to an intermediate way station disposed on the route.
The system also includes a smart contracting module. The module includes computer program instructions executing in the memory of the host computing platform and enabled to perform receiving in the intermediate way station digital terms of shipment for the transport of the item, and a digital contract of transport of the item from the originator to the destination and matching the terms of the shipment to pre-stored data indicating an ability of the way station to meet the terms of the shipment. The instructions also are enabled to perform identifying portions of the contract corresponding to the way station and matching requirements of the identified portions to pre-stored rules indicating a willingness of the intermediate way station to agree to particular contract term. Finally, the instructions are enabled to perform affixing a digital signature for the intermediate way station to the digital contract on condition that the terms and requirements match and then selecting a next way station on the route and, directing transmission of the digital contract and terms of shipment to the selected next way station, but otherwise transmitting a message to the originator rejecting the digital contract.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
Embodiments of the invention provide for dynamic distributed smart contracting. In accordance with an embodiment of the invention, a smart contract includes one or more digital terms of shipment for the transport of an item, and one or more digital signatures indicating acquiescence to the digital terms by each party to the transport of the item. The smart contract is propagated from a source way station disposed on a route between an originator of shipment of the item and a destination indicated for the item, to each intermediate way station on the route. At each way station, the terms of the shipment are matched to pre-stored data indicating an ability of the way station to meet the terms of the shipment. To that end, each way station identifies portions of the contract corresponding to the way station and matches requirements of the identified portions to pre-stored rules indicating a willingness of the way station to agree to particular contract terms. If agreeable, then a digital signature for the way station is affixed to the digital contract and a next way station on the route selected. Finally, the digital contract and terms of shipment are transmitted to the selected next way station.
In further illustration,
In operation, a smart contract 110 is received in a first one of the way stations 130A. The smart contract 110 includes a set of digital terms 120, with portions of the digital terms 120 being assigned to different ones of the way stations 130A, 130B, 130N. The digital terms 120 specify conditions on the transport of an item, such as a minimum time permitted to transport the item, a price of transport, a required mode of transport, and the like. The digital hub 140 of the way station 130A receives the smart contract 110 and parses the digital terms 120 in order to identify a portion of the digital terms 120 directed to the way station 130A. The digital hub 140 then applies the terms of the identified portion to the way station term rules 170 in order to determine if all of the terms of the identified portion are able to be supported by the way station 130A. If so, the digital hub 140 signs the smart contract 110 by encrypting the identified portion of the digital terms 120 with a private key 160A of the way station 130A making the agreed upon terms of the identified portion, immutable.
Thereafter, the way station 130A selects a next way station 130B to receive the smart contract 110. In this regard, the next way station 130B is selected, for instance, by querying each of a selection of prospective next way stations 130B to determine which is able to acquiesce to the most number of the digital terms 120. Alternatively, a cache of known capabilities of a selection of prospective next way stations 130B may be queried to determine which is able to acquiesce to the most number of the digital terms 120. As yet another alternative, a cache of known capabilities of a selection of prospective next way stations 130B may be queried to determine which is able to acquiesce to the most number of the digital terms 120 in order to produce a subset of the way stations 130B and the way stations 130B in the subset may then be queried to determine which is able to acquiesce to the most number of the digital terms 120. In any event, once a next way station 130B is selected, the smart contract 110 is transmitted to the next way station 130B in the transport route and the process continues. When the smart contract 110 has been processed and signed by the destination way station 130N, the smart contract 110 is then returned to the originator with the knowledge that every term of the digital terms 120 has been agreed to by each one of the way stations 130A, 130B, 130N in the transportation route.
The process described in connection with
Each smart contracting module 300 includes computer program instructions operable upon execution in memory of a corresponding computer, to receive a smart contract 250 and to extract digital terms from the smart contract 250. The program instructions additionally are operable to apply pre-stored rules 240 to the extracted digital terms in order to identify any terms not acceptable to a corresponding one of the way stations. The program instructions are further operable to sign the smart contract 250 with a private key 270 of the corresponding one of the way stations to the extent that all of the digital terms are deemed acceptable by the pre-stored rules. Finally, the program instructions are operable to select a next one of the way stations on the route and to forward the signed smart contract to the selected next one of the way stations. In this regard, the program instructions are enabled to retrieve from cache 260, known capabilities of a selection of prospective next way stations to determine which is able to acquiesce to the most number of the terms of the smart contract 250 so as to select the way station to receive the smart contract 250 most likely to be able to acquiesce to the terms of the smart contract 250.
In even yet further illustration of the operation of the smart contracting module 300,
In block 350, to the extent that the pre-stored rules when applied to the digital terms fails to identify any unacceptable terms, the smart contract is signed by the recipient way station by encrypting the digital terms of the smart contract pertaining to the recipient way station with a private key of the recipient way station. Thereafter, in block 360 a list of next potential way stations in the route is determined and in block 370, each of the way stations in the list is queried for respective capabilities in transporting the item to the destination way station. In block 380, one of the way stations best matching the digital terms of the smart contract is selected and in block 390, the smart contract is forwarded to the selected way station.
