Description

Method for managing the lifecycle of digital content, a computing device for token management using the same, and a feed service server using the same The present invention relates to a method for managing the lifecycle of digital content, a computing device for token management using the same, and a feed service server. More specifically, it relates to a method for controlling the lifespan of digital content according to a token assigned to digital content provided through a feed service, a computing device for token management using the same, and a feed service server. A blockchain network is a distributed ledger system without a central administrator that operates by having network participants jointly record and verify transaction history. In this system, each block contains transaction information and the hash value of the previous block, allowing blocks to be linked in a chain. This guarantees data integrity and immutability, thereby ensuring the reliability of data management. Consequently, while early blockchain networks were primarily used for token-based transactions in the financial sector, they are now utilized in various fields following the introduction of smart contracts, which enable the automatic execution of transactions when predefined conditions are met. For example, blockchain network technology can be utilized in feed services. A feed refers to displaying digital content uploaded through platforms such as social network services (SNS) to users. In other words, a feed service is a service that can induce user participation by organizing and displaying various digital content, such as photos, videos, advertisements, and news containing related content or composition, in the social media space based on the user's interests, search history, and activity history. Conventional feed services are operated through a centralized system, and since the feed service operator directly intervenes to handle costs and distribute profits, there is a possibility that profit distribution may not be fair if a problem arises with the feed service operator. Additionally, since digital content is uploaded to a centralized repository, there may be issues with content management if a problem occurs with the repository. Therefore, attempts are being made to implement it as a tokenomics system to enable fair profit distribution without intervention by the feed service operator while increasing the safety of the system. For example, regarding the lifespan management of digital content, Filecoin manages the lifespan of digital content by entering into a contract to store digital content for a certain period, maintaining pinning of the digital content during the contract period, and extending its lifespan through renewal when the contract ends; Arweave does not require additional lifespan management by storing digital content permanently with a single storage; and Sia, based on a cloud storage model, allows users to store digital content by determining the storage period through a storage contract and manage the lifespan of the digital content through renewal when the contract ends. However, these methods have the problem of lacking the flexibility to autonomously control the lifespan of digital content by content owners or users (e.g., feed service users). Furthermore, regarding the method of distributing rewards, Filecoin utilizes Proof-of-Replication (PoRep) and Proof-of-Spacetime (PoSt) consensus mechanisms to allow storage providers to receive rewards, which are paid after verifying that digital content has been securely stored for a certain period. In contrast, Arweave permanently stores digital content with a single save, so storage providers receive rewards based on the initial cost paid by the user, with no additional compensation provided. Sia distributes rewards for storage contracts through Sia coins, and similar to Filecoin, storage providers can receive rewards if they maintain digital content for a certain period. However, these methods have the drawback of not being able to distribute rewards in real time. Furthermore, regarding the method of pinning digital content, Filecoin and Sia allow storage providers to maintain pinning for the duration stipulated in the storage contract, whereas Arweave allows pinning to be maintained permanently so that digital content can be stored indefinitely. However, these methods have the drawback that content owners or users (e.g., feed service users) cannot directly intervene in maintaining pinning of digital content or autonomously control when to change the pinning status. Therefore, improvement measures are required to resolve the aforementioned problems.
