Hold on ... the www source that Sotheby is auctioning? The angle brackets are wrong! They've been --yes --HTML encoded from '<>' to '& lt; & gt;'. Lol. Https://t.co /vb7clOETfU pic.twitter.com/kb1ugoPyok

Mikko Hypponen, a researcher at security company F-Secure, found an error in the NFT animationthat Sotheby's, who was in charge of the auction, published on the site.

The mistake is that '<' and '>' are '& lt;' and '& gt;' (& is half-width in the original text), and the first appearance is only 3 seconds at the beginning of the animation.

In HTML and XML, '<' and '>' are symbols that indicate the start and end points of tags, so even if you intend to enter them as characters, they will be read as tags. Therefore, when using it as a simple character, it is necessary to use '& lt;' and '& gt;'. In the animation, '<' and '>' that do not need to be converted have been converted.

The animation was later replaced with a corrected mistake.

The NFT also includes a poster of the 'WorldWideWeb' source code output by Tim Berners-Lee in Python, but the poster correctly displays '<' and '>' and is included in the NFT. I don't know if there is a mistake in the animation or if there was a conversion error when Sotheby's prepared a separate sample.

Since NFT is 'digital data with a non-forgery encryption certificate' issued and traded on the blockchain, even if this NFT animation initially contains errors, the original file The certificate exists on the blockchain.

For this reason, news site Ars Technica notes that just as misprinted currencies are worth more, so is the art of 'typo'.
