## Background
TECHNICAL FIELD
The present invention relates to a service providing method performed by a server of a music platform using a blockchain-based non-fungible token (NFT), and more particularly, to a service providing method that may provide a service related to a sound source in a music platform by issuing a blockchain-based NFT for the sound source.
RELATED ART
Currently, with the development of global music industry, platforms that support sound source-related services are emerging. Through such a platform, a right holder having a copyright for a corresponding sound source is securing revenues for the copyright of the sound source. However, in the case of the market related to music industry, the market is being operated mainly by large entertainment companies or distribution companies. Therefore, copyright fees (e.g., sound source fees) are being unequally distributed to the right holder having the copyright of the corresponding sound source.
Also, a blockchain-based non-fungible token (NFT) is being concentrated as technology that may clearly guarantee ownership for assets with authorization of ownership such as copyright. The NFT may refer to new digital assetization-related technology that assigns a unique digital certificate to an asset using blockchain-based encryption technology.
As such, the blockchain-based NFT that may clearly guarantee ownership for assets, such as copyright, and may support a direct transaction for various users is expected to apply to the music industry. However, there are not many or almost no services that support a music platform using a blockchain-based NFT or a sound source-related service so far.
