Description

METHOD AND SYSTEM FOR PERFORMING DATA TRANSACTIONS IN EXCHANGE FOR ASSETS ON A NETWORK TECHNICAL FIELD The invention relates to a method for performing data transactions in exchange for assets on a network according to the preamble of claim 1. The invention also relates to a system for performing data transactions in exchange for assets on a network. The invention in addition relates to a computer program and a computer readable medium.
BACKGROUND ART Performance of data transactions on a network employing blockchain technology is common for e.g. bitcoin transactions. Performing other types of data transactions in exchange for assets on a network such as a blockchain network is also known. Such a blockchain network may comprise a family of network members having communication and processing means for communicating and processing said data transactions within said blockchain network.
It is also known to use so called smart contracts, i.e. an executable piece of code within the blockchain technology. For example US2017011460 discloses a method for performing transactions of securities based on smart contracts.
Such a smart contract may be utilized in various use cases when exchanging assets on the blockchain. In particular a smart contract can be used to perform atomic swaps, wherein a party X inputs assets to be swapped with assets inputted by party Y. When both parties committed their assets and digitally signed the smart contract, the atomic swap is performed on the blockchain.
To make atomic swaps between arbitrary data and assets on a blockchain, initiated by the data provider by utilizing a smart contract the asset committer may simply obtain the contract and locally commit the funds and sign it without broadcasting the actions to the network. Thus the data can be obtained without publicly committing any assets.
There is thus a need for facilitating performance of data transactions in exchange for assets on a network.
OBJECTS OF THE INVENTION An object of the present invention is to provide a method for performing data transactions in exchange for assets on a network which facilitate fair trade.
Another object of the present invention is to provide a system for performing data transactions in exchange for assets on a network which facilitate fair trade.
SUMMARY OF THE INVENTION These and other objects, apparent from the following description, are achieved by a method, a system, a computer program and a computer readable medium, as set out in the appended independent claims. Preferred embodiments of the method and the system are defined in appended dependent claims.
Specifically an object of the invention is achieved by a method for performing data transactions in exchange for assets on a network. Said network comprises a family of network members having communication and processing means for communicating and processing said data transactions within said network. The method comprises the step of providing an agreement contract intended to be digitally signed by a network member acting as a data provider, said agreement contract being intended to be digitally signed by at least one other network member acting as an asset committer and to be made available for network members as signed, said agreement contract specifying rules for obtaining data to be provided. The method further comprises the step of, upon signing of said agreement contract by said data provider and said at least one other network member, providing an enforcement contract intended to be digitally signed by said data provider, said enforcement contract pointing back to the previously signed agreement contract and is intended to comprise, in encrypted form, said data to be provided, said enforcement contract being intended to be signed by said at least one asset committer.
Hereby fair trade for performing data transactions in exchange for assets on a network is facilitated in that other network members of the family of network members has seen the agreement contract signed by the network member acting asset committer.
Thus, each network member comprises communication means for communicating data transactions within said network and processing means for processing said data transactions within said network.
According to an embodiment one or more network members may comprise recording means for recording data within said network.
According to an embodiment one or more network member may comprise storing means for storing data within said network.
Each network member may comprise any suitable computer device, server device, processing unit, control unit or the like.
The step of providing an agreement contract digitally signed by a network member acting as a data provider is performed by means for providing an agreement contract. The step of providing an agreement contract comprises the step of generating an agreement contract and digitally signing said generated agreement contract by said data provider.
The method thus comprises the step of making said signed agreement contract available for network members, preferably all network members. According to an embodiment said agreement contract is made available to network members when it has been provided. For a blockchain network said agreement contract is made available to all network members when it has been provided.
According to an embodiment the method comprises the step of determining whether said asset committer has digitally signed said agreement contract. The step of determining whether said asset committer has digitally signed said agreement contract is performed by determining means.
The step of providing an enforcement contract comprises according to an embodiment the step of providing an empty enforcement contract which may be digitally signed by data provider and asset committer and be provided, in encrypted form, with said data to be provided to said asset committer.
The step of providing an enforcement contract comprises the step of generating an enforcement contract and digitally signing said generated enforcement contract. The step of generating an enforcement contract is performed by means of enforcement contract generation means. Said enforcement contract is thus configured to be generated by means of enforcement contract generation means.
The step of providing an enforcement contract is based on information of whether said agreement contract has been digitally signed by said asset committer. The enforcement contract is thus configured to be generated when said agreement contract has been digitally signed by said asset committer.
Said enforcement contract is configured to point back to the previously signed agreement contract. Said enforcement contract is thus configured to be connected to the previously signed agreement contract.
According to an embodiment the method comprises the step of making said signed enforcement contract available for network members, preferably all network members. According to an embodiment said enforcement contract is made available to network members when it has been provided. For a blockchain network said enforcement contract is made available to all network members when it has been provided.
According to an embodiment the method comprises the steps of: determining by determining means if said enforcement contract has been signed by said at least one asset committer within a predetermined time limit, if said enforcement contract has been signed by said data provider within a predetermined time limit, and if said enforcement contract comprised said data to be provided within a predetermined time limit; and if it is determined that said at least one asset committer and said data provider have signed said enforcement contract and said data was comprised in said enforcement contract said transaction is determined to be completed, and if it is determined that said at least one asset committer has not signed said enforcement contract penalties for said asset committer specified in said rules for obtaining data to be provided are enforced, and if it is determined that said data provider has not signed said enforcement contract and/or said data was not provided penalties for said data provider specified in said rules for obtaining data to be provided are enforced. Hereby efficient control of said transaction is facilitated for securing fair trade and proper compensation/penalty is facilitated if asset committer or data provider does not commit to the signed agreement. According to an embodiment of the method said agreement contract and said enforcement contract pointing back to said agreement contract constitute a two-phase smart contract constellation. Hereby a kind of efficient electronic handshake of the agreement is facilitated for said fair trade.
According to an embodiment of the method said network is configured as a blockchain network employing blockchain technology. By applying a blockchain network employing blockchain technology for performing said data transactions in exchange for assets by means of said agreement contract and said enforcement contract pointing back to said agreement contract said transactions may be efficiently performed by network members not necessarily trusting each other, the blockchain technology facilitating efficient and reliable control of the time of said transactions.
According to an embodiment of the method the step of providing an enforcement contract is performed automatically. The step of automatically providing an enforcement contract is based on information whether the asset committer has signed the agreement contract. The enforcement contract is thus configured to be automatically generated when said agreement contract has been digitally signed by said asset committer and said data provider.
Specifically an object of the invention is achieved by a system for performing data transactions in exchange for assets on a network. Said network comprises a family of network members having communication and processing means for communicating and processing said data transactions within said network. The system comprises means for providing an agreement contract intended to be digitally signed by a network member acting as a data provider, said agreement contract being intended to be digitally signed by at least one other network member acting as an asset committer and to be made available for network members as signed, said agreement contract specifying rules for obtaining data to be provided. The system further comprises means for providing an enforcement contract intended to be digitally signed by said data provider upon signing of said agreement contract by said data provider and said at least one other network member, said enforcement contract being arranged to point back to the previously signed agreement contract and is intended to comprise, in encrypted form, said data to be provided, said enforcement contract being intended to be signed by said at least one asset committer.
According to an embodiment the system comprises means for determining if said enforcement contract has been signed by said at least one asset committer within a predetermined time limit, if said enforcement contract has been signed by said data provider within a predetermined time limit, and if said enforcement contract comprised said data to be provided within a predetermined time limit; and means for determining said transaction to be completed if it is determined that said at least one asset committer and said data provider have signed said enforcement contract and said data to be provided was comprised in said enforcement contract, and means for enforcing said enforcement contract penalties for said asset committer specified in said rules for obtaining data to be provided if it is determined that said at least one asset committer has not signed said enforcement contract; and means for enforcing said enforcement contract penalties for said data provider specified in said rules for obtaining data to be provided if it is determined that said data provider has not signed said enforcement contract and/or said data was not provided.
