Cryptocurrency logo

DeSo is the official Web3 sponsor of the MLH Hackathon League and the first Layer 1 blockchain custom-built for decentralized social media applications. While a blockchain like Avalanche costs $0.50+ to store just a 200-character post, the DeSo blockchain is built with custom indexing and storage optimizations which make it 10,000X cheaper to store social content on-chain! In order to qualify for the contest, you must launch an app that writes to the DeSo blockchain and implements DeSo identity. While social media apps are a great fit for DeSo, you can also build financial apps, marketplaces, and more on the DeSo blockchain. For inspiration on project ideas, you can check out some of the existing 200+ apps already live on DeSo at Bithunt.com as well as our DeSo APIs. The Best Use of DeSo gets $100 worth of $DESO coin & an exclusive DeSo branded tumbler!
