ERC-721 is a free open standard that describes how to build non-fungible or unique tokens on the Ethereum blockchain.

Who invented non fungible tokens. To begin with NFTs were invented by digital artist Kevin McCoy and tech entrepreneur Anil Dash in 2014. Non-Fungible tokens blew up in 2020 in the middle of the pandemic but it blew up even further in 2021 in 2020 the total NFT sale volume was 250 million by the first quarter of 2021 that number became 2 billion. John Watkinson and Matt Hall in June 2017 created CryptoPunks.

But of course this term wouldnt even be a thing if the alternative non-fungible tokens NFT hadnt become so note-worthy since Cryptokitties took Ethereum by storm in 2017. This opened many peoples eyes to the potential of non-fungible tokens. A non-fungible token of course is a token that is not fungible but defining things by what they are not is.

Axiom Zen then spun out a company called Dapper Labs which secured 15 million dollars in. This was the first experiment on a Non-fungible-token created via on-chain metadata enabled by Namecoin and it was linked to a unique work of art. It is defined under the ERC721 standard.

In search of a unique and rare token Dieter Shirley invented an NFT standard ERC-721 in September 2017 thus democratising this new type of non-fungible blockchain token. For this ERC721 was invented. But tech-world opportunism has struck again.

Non-fungible tokens arent a harmless digital fad theyre a disaster for our planet. But tech-world opportunism has struck again. When Pepperium was invented in March of 2017 two creators decided to alter the digital innovation to make it easier to send information.

The Ethereum blockchain hosts a majority number of NFTs that are present in the crypto universe today. When we invented non-fungible tokens we were trying to protect artists. This NFT allows people to create these unique characters on the Ethereum blockchain.
