Building an open digital economy

At OpenSea, we’re excited about a brand new type of digital good called a non-fungible token, or NFT. NFTs have exciting new properties: they’re unique, provably scarce, tradeable, and usable across multiple applications. Just like physical goods, you can do whatever you want with them! You could throw them in the trash, gift them to a friend across the world, or go sell them on an open marketplace. But unlike physical goods, they’re armed with all the programmability of digital goods.

A core part of our vision is that open protocols like Ethereum and interoperable standards like ERC-721 and ERC-1155 will enable vibrant new economies. We’re building tools that allow consumers to trade their items freely, creators to launch new digital works, and developers to build rich, integrated marketplaces for their digital items.

We’re proud to be the first and largest marketplace for NFTs.

What is an NFT?

NFTs operate on blockchain technology. The blockchain is basically a large, digital, public record. The most popular blockchains are distributed across many nodes (read: people’s computers), which is why you’ll hear them described as “decentralized.”

What is web3?

In 2014, Gavin Wood, co-founder of the Ethereum blockchain and the Web3 Foundation, coined the term in a blog post.

What is blockchain?

A blockchain is a decentralized record that gets its name from how it stores its data. Once a set of transaction data reaches a certain size, it forms a “block.” This is where every transaction on a blockchain is validated and then permanently stored. The “chain” part of a blockchain is a series of consecutive blocks linked together, forming the immutable ledger.
