Show HN: ChainDisco – a toy to explore recent NFT activity

Hi all,

I wanted to play with blockchain data at scale and ended up making this "endless waterfall" visualization of recent NFT events. Hopefully it's fun way to poke around at the sometimes amusing, sometimes disturbing world of NFT imagery.

Under the hood, ChainDisco talks to an Ethereum node that I run myself; every time a new block is mined, ChainDisco looks for NFT mints/transactions and for the creation of new ERC-721 and ERC-1155 contracts. From there, it grabs metadata, imagery, and pricing information. The metadata lands in a PostgreSQL instance.

I think of this as an anti-portfolio toy: as I mention in the "about" dialog, ChainDisco offers little help with purchasing or deciding what to purchase. That's intentional; you might say I'm... uh, a touch bearish on essentially all crypto assets.

Happy to answer any questions. This is one of several toys I've built while trying to wrap my head around the madness that is Web3/crypto.
