-title: Are we zk-Cardano yet?
-date: 2023-08-07
----
-
-Not so long ago Emurgo announced they were doing a Cardano centered hackathon. 
-It was a welcome prospect - very few similar such events seem to exist in the space.
-Things went monotonically south ever since the announcement, but that's a different story. 
-
-One particularly interesting quirk was that of the three "tracks" of the hackathon, 
-one was _Zero Knowledge_ (aka zk). 
-Why particularly interesting quirk? In some sense it is not suprising:
-zK has been very trendy these last few years around blockchains.
-However, building on Cardano is notoriously challenging.
-Building with zk on a zk-native blockchain is itself a very steep learning curve.
-So combining the two, zk on Cardano seemed... a bit mad. 
-
-This post is bourne out of a best effort of how far "zk on cardano" can be pushed. 
-
-## What is zk?
-
-There is no shortage of explanations describing what zk is [TODO: Links].
-There is also a reasonable breath to the field of zk that includes things like distributed compute.
-Zk involves some really neat maths that lets you do some seemingly magical feats,
-and pairs well with blockchain in extending what is functionally possible.
-Let's stick to a simple and prototypical example. 
-
-Suppose Alice and Bob are playing battleships.
-The game begins with Alice and Bob placing their ships within their own coordinate grid.
-They then take in terms picking coordinates to "bomb". 
-If they hit nothing, then their turn ends, but if they hit a ship then they guess again. 
-The winner is the first to sink all their oponents ships. 
-
-Alice knows Bob has a reputation of being a notorious liar; how can she enjoy the game?  
-Each guess she makes, Bob says gleefully shouts "Miss!".
-She can't ask Bob to show he's not lying by revealing the actual locations of the ships.
-She could ask Charlie to independently verify Bob's not lying, 
-but then what if Charlie is actually on team Bob and also lies. 
-Or Bob might suspect Charlie is actually on team Alice, slyly brought in to give could Alice some hints.
-
-Is there a way that Bob can prove to Alice that each guess is a miss, 
-but without revealing the locations of the ships either to Alice or anyone else?
-
-The answer is yes. 
-Using zk Bob can produce a proof each time Alice's guess misses if and only if it honestly does. 
-Alice can inspect each proof and verify Bob's response.
-Alice can interogate the proof as much as she wants, but she won't learn anything more than
-her guess was a miss. 
-
-There are multiplitude of different ways to do this,
-but essentially it involves modelling the problem as a bunch of algebra
-over finite fields - like a lot of cryptography. 
-
-What's the snark of zk-snark?
-Snark stands for _Succinct Non-Interactive Argument of Knowledge_. 
-And without saying anything more: it means that Alice has to do way less algebra than Bob. 
-In applications this is important, because Bob might not be able to lie anymore, 
-but he could still waste Alice's time.
-
-
-## Sudoku snark
-
-Sudoku snark was the entrant to Emurgo hackathon. 
-The summary/ pitch/ story deck is [here](https://pub.kompact.io/sudoku-snark).
-Links to associated repos [plutus-zk]() and [sudoku-snark]().
-
-Just after the hackathon got underway there was a large PR merged into the main branch of plutus.
-It's a mammoth PR that is the culmination of many many months of work. 
-In it were some fundamental primitives needed for running zk algos. 
-
-The idea of the project was as follows:
-
-- write a validator implementing a zk algorithm with the new primitives
-- write a programme to generate the setup and proofs
-- try to get a version of hydra running this newest version of plutus. 
-
-Unsurprisingly to anyone who's hung around the Cardano repos long enough, 
-this final part is where things got stuck. 
-Things got as far as running a cluster of nodes in the conway era supposedly with the latest plutus
-but some unrelated changes seemed to thwart any chance of building transactions. 
-
-The validator uses [groth16].
-In part because this was already mostly available from the plutus repo itself. 
-It is also the most obvious candidate to begin with.
-It's relatively mature, relatively simple, can be implemented from the new primitives, 
-and, importantly in cardano land, has small proof size. 
-(As far as I know, the smallest of comparable algos.)
-
-The program to generate the setup and proofs uses the arkworks framework.
-Again this was initially inspired by a script from the IOG team. 
-
-The choice of game, sudoku, was in turn inspired by an arkworks example.
-It's not the most compelling of choices, but it did for now.
-
-The intended game play involved locking ada at a utxo 
-spendable only if a player could provide proof you knew the solution.
-And through the magic of zk, not disclosing to the competition the solution itself. 
-Other details were TBC: is it first and second prizes? are players whitelisted? 
-
-## So are we zk-Cardano yet?
-
-We're close.
-
-There is potentially still quite a stretch between being in the plutus repo and being run on-chain. 
-The word on the street is that it might happen before the end of 2023. 
-
-Before it's available on mainnet there will be versions the cardano node available, 
-and so possibly plumbable into hydra without causing oneself an aneurysm.
