![]() But these proposals are incomplete, because the blockchain is merely a ledger. And with the development of blockchain technology a decade ago, more recent proposals have discussed putting bills of lading on a blockchain. Proposals to update paper bills of lading with an electronic equivalent have circulated for many years. ![]() As a paper document, however, the bill of lading (often in multiple counterparts) is a critical bottleneck and source of risk. It indicates ownership of goods in transit, evidences the terms of the contract of carriage, and shows where, when, and to whom the goods were conveyed at every step between origin and ultimate destination. Evolving over centuries and well developed by the time of the medieval lex mercatoria, the bill of lading is a paper form specifically contemplated and described in the key treaties enabling modern cross-border sales of goods-the Vienna Convention, the Hague- Visby Rules, and the U.S. The bill of lading is a venerable institution in international trade. But none of these are cryptographically secure in the way NFTs are, and none of them combine proof of authenticity and proof of ownership in a single instrument. Goods already are stamped with bar or QR codes, expensive products typically have serial numbers or other unique identifiers, and software often is accompanied by one- time-only passwords. There are, of course, other digital representations of physical assets. Also, they are “extensible.” This means that NFTs can be added together or merged in order to create a new NFT in a traceable way. This means that the NFT itself indicates who owns it-when it was created and by whom, who controls it now, and every transaction leading from the original to the current owner-at all times. For example, they inherently include ownership information. This means NFTs are not useful as currency, but are valuable as incorruptible identifiers. So while one NFT may have the same market value as another NFT, no two NFTs are the same. An NFT, by contrast, is uniquely identified in the blockchain. In the same way that one Euro is equal to any other Euro, one Bitcoin has the same value and same characteristics as any other Bitcoin. A unit of cryptocurrency is a fungible token, meaning it is identical to any other unit of cryptocurrency. Cryptocurrencies and NFTs differ in a critical respect. But an encrypted block cannot be changed without altering all prior blocks – and alerting all other users in the blockchain. The blockchain itself is “public” in the sense that every transaction is visible to all participants. A blockchain is a series of cryptographically linked records. Like cryptocurrencies, NFTs are applications of blockchain technology. Thus artists have started selling digital artwork authenticated by NFTs, gaming companies can sell unique in-game products, and athletic leagues have started selling digital “cards” depicting key moments in sporting events. It can be a photo, a logo, a meme, a music album, a basketball highlight, a collage, a tweet, a newspaper article, a video basically, anything that can get online … - Brian Gordon … Smith will auction off the horror anthology as a non-fungible token, with the owner gaining the rights to exhibit, distribute and stream the movie.The non-fungible token (NFT) has emerged as a way of authenticating unique digital assets. Dave Vellante also : the asset that is represented by a non-fungible token A non-fungible token is, most simply, a unique digital asset. ![]() Eileen Brown Nonfungible tokens each have their own unique value, so they're not tradable on a like-to-like value basis. Helen Sullivan Non-fungible tokens are used to verify unique items such as digital art and digital ownership of other items. : a unique digital identifier that cannot be copied, substituted, or subdivided, that is recorded in a blockchain, and that is used to certify authenticity and ownership (as of a specific digital asset and specific rights relating to it) Non-fungible tokens … are electronic identifiers confirming a digital collectible is real by recording the details on a … database known as a blockchain.
