When entering the ZK space, it’s easy to be overwhelmed. Everyone is shilling their own protocol, and there are a ton of different proving standards and papers coming out every day. Folks often have similar questions on how to think about different ideas and protocols security, efficiency, and tradeoff wise. Unfortunately, its very hard to quickly distinguish what is worth investing into, and all of the precise security guarantees or undisclosed “gotchas”.

I think this is a good middle ground between the oversimplified layman-oriented quantum news articles, and the hyper academic quantum computing papers that are hard for a cryptographer to parse. As the field rapidly evolves, things here may become outdated or wrong. Feel free to leave thoughts/comments/corrections on the hackmd draft of this post! An old version was previously also posted on zkresearch and a version that explains how to migrate Ethereum was posted on ethresearch.

The lack of trustless integration with web2 is one of the leading reasons that blockchains feel siloed from the rest of the world – there’s currently no way of trustlessly interoperating with the exabytes of existing information online, built up over decades by millions of users, that plug into every system we use every day. The resulting isolation of blockchains leads to fully contained apps and ecosystems: a great fit for DeFi or gaming, but a terrible fit for prosocial applications trying to weave themselves into our daily lives.

Thanks to Kobi Gurkan, Wei Jie Koh, Vivek Bhupatiraju, Remco, Wei Dai, Nalin, gubsheep, ludens, Blaine Bublitz, Prof. Kalai, Prof. Vaikuntanathan, Prof. Boneh, Richard Liu, Piotr Roslaniec, Lily Jordan, and Riad Wahby [and probably tons of other folks I’m missing, please dm me if I did!] for making this work possible :)
Why do we want PLUMEs? The proliferation of advances in zkSNARK applications has created a useful new privacy primitive: a user can prove statements about their identity without revealing their full identity.

Intro to vickrey.xyz Thanks to an idea from @0xngmi, a team of @real_philogy, @outdoteth, and me recently prototyped the first maximally private Vickrey auctions on-chain [repo here] (also shoutout to @0x_Beans and @rauchp_ for some additional analysis and help). Unlike past implementations of Vickrey auctions on-chain, vickrey.xyz leverages uninitialized CREATE2 addresses to not only conceal the size of bids, but their existence (more precisely, their association). This is unlike existing implementations, which only hide the amount, but disclose the other bidders’ identities and their maximum possible bids.
