New York: Twitter co-founder Jack Dorsey put his first tweet up for sale with bids reaching $2.5m.
“Just setting up my twttr,” the post, sent from Mr Dorsey’s account in March 2006, reads.
It will be sold as a non-fungible token (NFT) – a unique digital certificate that states who owns a photo, video or other form of online media.
But the post will remain publicly available on Twitter even after it has been auctioned off.
The buyer will receive a certificate digitally signed and verified by Mr Dorsey, as well as the metadata of the original tweet. The data includes information such as when the tweet was posted and the text content.
However, most of the information is already publicly available.
Tweets are the latest digital assets to be monetised through so-called non-fungible tokens.
NFTs use the blockchain, the same distributed database technology underlying Bitcoin and other cryptocurrencies, to create unique certificates of ownership of any kind of digital goods.
