mint

  • mint only meta string property?
    • seems not to be able to mint an image file
  • to mint and show an image, the client app is necessary?

  • of cource, above tutorial source is based on the doc. only can mint meta

https://docs-blockchain.line.biz/ja/service-tutorial/Step2

  • there are two steps to mint NFT according to above tutorial
      1. 作成 (like defining metadata)
      1. 鋳造 (like minting)

Consideration

  • I don't know this platform needs to be based on blockchain.
  • users already have LINE account, and this platform was made by LINE.
  • it would be fine to use RDB, not blockchain. something like LINE pay, wallet.
    • I don't know whether those services use RDB or not.

Can we use LINE wallet as something like Metamask?

  • 既存サイト(OpenSeaなど)
    • 使えない。既存サイト側がLINE BITMAXまたはLINE Blockchainに対応する必要がある
  • 自作サイト(新規に自分でWebサイトを作成する場合)
    • LINEウォレット(正確にはLINE BITMAX Wallet)でMetamaskのように直接ログインすることはできない
    • LINEウォレット自体はLINE BITMAXまたはLINE Blockchain上のサービスでしかなく、Metamaskのような汎用的なウォレットサービスではない
    • LINEログインを実行して、そのLINEアカウントに紐づくウォレットに対してmintしたりすることは可能
