Chaincode Residency
June 10th - August 30th 2019



We invite you to immerse yourself in Bitcoin this summer. Chaincode Labs is hosting a Bitcoin residency program in our offices in Midtown Manhattan, New York City.

This residency's format fuses an onboarding seminar period with a two-month project-based residency under the guidance of established Bitcoin and Lightning Network developers. This will allow residents to put their theoretical learnings to use by making meaningful contributions to open-source projects.

Becoming a Bitcoin Protocol Developer

(~2-3 weeks) Sessions to bootstrap the knowledge of developers by diving deep into security concerns, adversarial thinking, and approaches to Bitcoin and Lightning protocol design.

Project Based Learning

(~2 months) Unstructured time for residents to contribute to open-source projects or work on a personal project of their choosing. Each resident will be assigned a mentor for the duration of the program.
