We have up to 70.000 USD in prizes to be split into different tracks

Main track

All projects automatically apply for a main track. 

Main track prize pool is 45.500 USD and it can go higher depending on whether some sponsors decide to have a sponsored track or not.

Sponsored tracks

Silver and gold sponsors have the possibility to get a sponsored track, At the moment with all the sponsors we have up to 31.500 USD to split in tracks

Updates about sponsored tracks are going to be posted here

Mina & O(1) Labs track

Mina is the world’s lightest blockchain, powered by participants. Rather than apply brute computing force, Mina uses advanced cryptography and recursive zk-SNARKs to design an entire blockchain that is about 22kb, the size of a couple of tweets. It is the first layer-1 to enable efficient implementation and easy programmability of zero knowledge smart contracts (zkApps). With its unique privacy features and ability to connect to any website, Mina is building a private gateway between the real world and crypto—and the secure, democratic future we all deserve

They will be providing prizes for zkApps built for Mina Protocol using SnarkyJS

1st Prize: $1,400

2nd Prize: $1,000

3rd Prize: $800

$300 pool for anybody (after 3rd Prize) who submits a qualifying project built with SnarkyJS

RiscZero track

RISC Zero is a zero-knowledge verifiable general computing platform based on zk-STARKs and the RISC-V microarchitecture. Our suite of products enable developers to use existing tools and languages, such as Rust, to build performant, upgradable, and secure ZK programs. Additionally Bonsai, our ZK proving network, enables hyper performant parallel proving and on chain proofs for any program built on our zkVM. 

Bounty #1 $2500 - Build New Applications Using RISC Zero

For the Lambda ZK Week this year we are excited to award bounties for projects that demonstrate innovative and compelling uses of our zkVM and/or Bonsai, our ZK proving network.

Additionally, for projects looking to bring ZK to Ethereum and/or Gas-efficient verifiable off chain computation, we are providing an early release of our ZK Coprocessor which enables on chain applications to access off chain verifiable compute through our zkVM and Bonsai.

****All bounty applications will be open source with the full source code available on GitHub.

Bounty #2 $1000 - Lambda X RISC Zero

Any projects that use both Lambda and RISC Zero to do something meaningful, novel, or inspiring where both technologies are relevant for the hack.

ZkDay Track

zkPitch Day is at the beginning of zkDay Paris. It is designed to showcase ZK Projects at various stages, from those embarking on their fundraising journey to those who have recently completed their seed round. 

The 1st Prize winning project from  Main Track  will be awarded a pitch ticket to present at zkPitch Day, taking place at zkDay Paris on July 19th, and compete for a $15,000 prize pool!
