Best Use of DeSo - MLH

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 blockchains like Avalanche or Solana cost $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/or 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!

Most Creative Use of Twilio - MLH

Twilio allows you to incorporate mobile messaging, phone calls and a ton of other awesome communication features right into your hackathon project using web service APIs. Are you building an e-commerce website and want to send text notifications or email confirmations once an order is completed? Or maybe your application needs to verify users based on their mobile numbers? Twilio makes all this possible and more. Build a hack that simplifies your life using any one of Twilio’s APIs for a chance to win a Twilio Swag Box and GameGo Console for you and each of your teammates!

Have you ever wondered how professional developers from companies like Peloton & Samsung collaborate and ship code to production?
