The evolution of Ethereum token standards

<p>About a year ago I made a video explaining the differences and similarities between ERC20, ERC721 and ERC1155 from a layperson's perspective (https://www.youtube.com/watch?v=Gt5C-j2b62U).</p> <p>I thought it might interesting to remake the video and release the audio as a podcast, but this time explaining the differences in the standards through the differences in the data structures within each contract that act as ledgers for the tokens.</p> <p>I found it interesting that ERC721 is at its core a flipped ERC20 data structure, and that ERC1155 is an ERC721 that encapsulates ERC20s. Plus there's a trick discussed which allows you to use ERC20 to mint a single NFT. So that's all great fun, isn't it?</p>
