Abstract

The present invention makes it possible to more simply create an auction system by separately delegating auction processes to a smart contract on a blockchain. Thereby, the minimum required functions on a seller-side system are three functions, namely a function for issuing smart contracts, a function for the notification of bid deadlines, and a function for scheduling the execution of bid notifications after a fixed period of time, while the minimum required functions on a bidder-side system are two functions, namely a function for searching and browsing smart contracts, and a function for updating a maximum or minimum price.

Description

スマートコントラクトを用いた競売システムAuction system using smart contract
　本発明は、案件毎の競売プロセスをブロックチェーンネットワーク上のスマートコントラクトに委譲することを特徴とする競売システムに関する。 The present invention relates to an auction system characterized by delegating an auction process for each item to a smart contract on a blockchain network.
　競売を行うシステムとして、クライアントサーバ型を用いたものが公知である。また、サーバを構築しないピアツーピア型でも同様のサービスを提供可能である。 A system using a client server type is known as an auction system. A peer-to-peer type in which no server is constructed can provide similar services.
　競売システムを構築する場合、クライアントサーバ型であればサーバ側で、ピアツーピア型であれば出品者側で、案件毎の競売プロセスを行えるようにシステムを構築する必要がある。本発明ではより簡便にシステムを構築する手段を提供する。 When constructing an auction system, it is necessary to construct a system so that the auction process for each item can be performed on the server side in the case of the client server type and on the exhibitor side in the case of the peer-to-peer type. The present invention provides a means for constructing a system more easily.
　本発明に係る競売システムは、案件毎の競売プロセスをブロックチェーンネットワーク上のスマートコントラクトに委譲する。 The auction system according to the present invention delegates the auction process for each item to the smart contract on the blockchain network.
　本発明においては、案件毎の競売プロセスのためのシステム構築に要する手間とコストを削減し、競売システムをより簡便に構築することを可能とする。 In the present invention, it is possible to reduce the labor and cost required to construct a system for an auction process for each item, and to construct an auction system more easily.
　出品者が物品を競売にかける場合を考える。まず出品者は、ブロックチェーンネットワーク上に「一定期間内に予定価格を上回る最高価格を付けた者を落札者とする」というスマートコントラクトを発行する。こうして発行されたスマートコントラクトは自由に閲覧可能とする。閲覧者の中で、落札しようとする者はスマートコントラクト上で管理される最高価格を更新する。一定期間が経ち、出品者はスマートコントラクトに対して入札締切を通知し、これをもって落札とする。このとき、落札者が決定し、ブロックチェーンネットワーク内部の仮想通貨の所有権が落札者から出品者に落札価格分移動する。
　本実施例で、出品者側のシステムに最低限求められる機能は、スマートコントラクトの発行機能と、入札締切の通知機能と、一定期間後に入札締切通知を実行するスケジュール機能の３点である。一方、応札者側のシステムに最低限求められる機能は、スマートコントラクトの検索及び閲覧機能と、最高または最低価格の更新機能の２点である。 Consider a case where an exhibitor places an item for auction. First, the exhibitor issues a smart contract on the blockchain network that “the highest bidder that exceeds the planned price within a certain period of time will be the winning bidder”. The smart contract issued in this way can be freely viewed. Among the viewers, those who try to make a successful bid update the highest price managed on the smart contract. After a certain period of time, the exhibitor notifies the smart contract of the bidding deadline and makes a successful bid. At this time, the winning bidder is determined, and the ownership of the virtual currency inside the blockchain network moves from the winning bidder to the exhibitor by the winning bid price.
In this embodiment, the minimum required functions of the system on the exhibitor side are three points: a smart contract issue function, a bid deadline notification function, and a schedule function for executing a bid deadline notification after a certain period of time. On the other hand, the minimum required functions of the bidder's system are the smart contract search and browsing function and the highest or lowest price update function.
　本発明は、すべての電子機器が人工知能を備え、自律行動する社会において、機器同士の調達に伴う競売処理への転用が可能である。 The present invention can be diverted to auction processing accompanying the procurement of devices in a society where all electronic devices have artificial intelligence and autonomous behavior.
