<a class="link" href="https://www.zkcompression.com/" target="_blank" rel="noopener noreferrer nofollow">ZK Compression</a> is a new primitive built on Solana that enables you to build applications at scale.Developers and users can opt to compress their on-chain state, reducing state costs by orders of magnitude while preserving the security, performance, and composability of the Solana L1.<h2 class="heading-node">Track Description</h2>This ZK Compression track, brought to you by Light Protocol, Helius, and the Solana Foundation, challenges participants to build innovative projects on the Solana that use zero-knowledge compression to achieve new levels of scalability, privacy, and security. Projects must use compressed tokens or compressed accounts in some capacity to be eligible, in addition to the following requirements.<h2 class="heading-node">Rewards</h2><ul class="list-node"><li>Best cToken integration for Solana Pay* - $2,000 USDC + 2 tickets for Solana Accelerate</li></ul><h2 class="heading-node">Eligibility Requirements:</h2><ul class="list-node"><li>The <a class="link underline decoration-[max(0.07em,1px)] underline-offset-2 links-accent:underline-offset-4 links-default:decoration-primary/6 links-default:text-primary-subtle links-default:hover:text-primary-strong links-default:contrast-more:text-primary links-default:contrast-more:hover:text-primary-strong links-accent:decoration-primary-subtle links-accent:hover:decoration-[3px] links-accent:hover:[text-decoration-skip-ink:none] transition-all duration-100" href="https://www.colosseum.org/files/Breakout%20Hackathon%20Official%20Rules%202025.pdf">Solana Foundation Rules</a> apply.</li><li>Each participant can have a maximum of 1 project submission count towards scoring in this side track.</li><li>*The Solana Foundation is sponsoring a dedicated prize pool for the best cToken Proof-of-Participation (POP) interface:The interface should:<ul class="list-node"><li>Let creators mint experience tokens (cTokens for airdrops)</li><li>Let attendees claim them by scanning a QR code</li></ul></li></ul><h2 class="heading-node">Judging</h2>The Breakout Hackathon's <a class="link" href="https://www.colosseum.org/files/Breakout%20Hackathon%20Official%20Rules%202025.pdf" target="">submission rules</a> apply.
