Vitalik Buterin Breaks Down GKR, The Mind-Blowing Crypto Tech You Can’t Ignore

by

Behold, the wonder that is the Goldwasser-Kalai-Rothblum (GKR) proof system! A brainchild of its eponymous creators, this dazzling piece of cryptographic wizardry, as explained by none other than Ethereum‘s founding guru, Vitalik Buterin, has revolutionized the world of mainstream cryptography-making it speedier and, dare we say, almost shockingly efficient. Who knew tech could be this…well, resourceful?

Ethereum’s Vitalik Buterin Decodes GKR: Fast, Cheap, and Surprisingly Smart

Yesterday, Vitalik, the Ethereum overlord, dropped some serious knowledge on GKR proofs in a guide that practically radiates brilliance. His explanation of this cryptographic gem reveals the engine under the hood of today’s ZK proving technologies. GKR proofs are the unsung heroes behind the breathtaking speed and performance we’ve come to expect from the likes of zkEVM and zkML. Hold onto your hats!

First unleashed upon the world in 2015, this scheme has grown into something of a superstar, thanks to its meticulously optimized development. GKR pulls off the astonishing feat of proving data with minimal fuss-only committing to the data’s starting and ending points, leaving all the pesky intermediary layers in the dust.

Buterin, ever the cryptographic philosopher, explains that these “commitments” are essentially fancy cryptographic data structures-think KZG or Merkle trees-that allow customers to pose specific queries about data without diving into the complexities in-between. It’s like asking for the final answer without bothering with all those pesky details. Genius, right?

Thanks to this elegant development, blockchain technologies like zkEVM and zkML now bask in the glow of ZK cryptography, enabling efficient proof generation on Layer 2 and seamless verification on Ethereum (ETH). Who says cryptography can’t be both beautiful and functional?

The Secret Sauce: Privacy with ZK-SNARK and ZK-STARK

But wait, there’s more! GKR doesn’t stop at speed and efficiency. This scheme is also an integral part of the privacy puzzle, working wonders alongside other ZK technologies to keep things hush-hush in the wild world of Layer 1 and Layer 2 interactions:

GKR is not “zero knowledge”: it only handles succinctness, not privacy. If you want zero knowledge, wrap the GKR proof in a ZK-SNARK or ZK-STARK.

In a recent, mind-bending move, Buterin took to his X Kohaku platform to unveil yet another development, a fork of Ambire, adding yet another layer of security to the Ethereum ecosystem. Who knew one man could juggle so many crypto breakthroughs?

And as always, Buterin reiterated that privacy and security are the true crowns of Ethereum (ETH). This man’s dedication to cryptographic excellence is almost… contagious.
