C27E: Cannabis Blockchain Convergence is LA’s premier 4/20 event uniting the cannabis and blockchain communities, centered on a 48-hour hackathon to develop decentralized applications and other blockchain solutions for the cannabis industry. Participation will be capped at 100 participants who will form teams of up to 7 people maximum to develop an idea/project/company that leverages blockchain to solve a real problem in the cannabis industry.

Beginning on Friday afternoon teams will form and work throughout the weekend on their idea which they will then pitch on Sunday to a judges panel who will determine the top 3 winners which will carry prizes including tokens, developer tools, and C27E swag.

Problem Statement:

“The cannabis industry is one of the fastest growing segments of the global economy despite lacking banking, digital marketplaces, trust between operators, and software tools. Cryptoassets have the potential to revolutionize how cannabis business is conducted from the ground up, yet there are currently no real solutions that are widely used and that actually solve problems.”

Lack of access to banking and merchant services, costly and burdensome seed-to-sale tracking software, and unsophisticated supply chain management software are all major challenges facing operators in the cannabis industry. Many of these seemingly intractable problems can be resolved in an elegant and effective manner by implementing solutions based on blockchain technology. C27E will bring together the world’s leading experts in cryptography and cannabis to develop blockchain solutions for the cannabis industry.
