# Why Ethereum?

The first NFT projects on Ethereum were launched in 2015. In other words, Ethereum's NFT scene has the most history and predates all of Ethereum's current alt-L1 competitors' NFT scenes. Ethereum has also maintained 100% uptime for the entirety of its existence, giving it the longest and most verified track record of successfully safeguarding NFTs to date.

Ethereum has the largest and most active development and creative community in the cryptocurrency world. Ethereum is the definitive and genuine capital of the crypto economy right now, whether it comes to cutting-edge L2 research or next-gen NFT cultural initiatives. It will never be easy to replicate or match this talent on a large scale.

ERC-721A is a game-changing implementation that allows you to save a lot of gas by minting many NFTs in a single transaction. When numerous NFTs are minted, this standard is extremely efficient.
