# Chaincode Labs > Source: https://timechain.wiki/wiki/chaincode-labs · TimechainWiki, the Bitcoin encyclopedia. (source · education · advanced) > **Chaincode Labs** (chaincode.com) is a New York–based organization that exists to support Bitcoin, combining protocol research, direct funding of open-source developers, and structured education that brings new contributors into Bitcoin Open Source Software (₿OSS). Its education flagship is the **₿OSS Challenge** (learning.chaincode.com) — a mentored, cohort-based program that runs from a one-month foundation of programming exercises into an optional two-month advanced phase with partner organizations and seminars, taught by contributors who have themselves come up through Bitcoin development. The register is **Advanced**: aimed at programmers who want to become Bitcoin protocol contributors, not at general learners. Chaincode's distinctive contribution is the *pipeline from capable programmer to working ₿OSS contributor*. --- ## Level **Advanced.** The ₿OSS Challenge assumes real programming ability and a serious time commitment (a stated minimum of ~10 hours per week). It is developer-onboarding for people aiming at protocol-level contribution, not an introductory or conceptual resource. --- ## Why this source matters Chaincode Labs occupies the deepest rung of the Bitcoin-education ladder: **turning capable programmers into Bitcoin Open Source Software contributors.** Getting started in ₿OSS is notoriously difficult — the codebase is demanding, the norms are unwritten, and the on-ramp is unclear. Chaincode's programs exist specifically to provide the guidance, curriculum, and mentorship that close that gap, which makes the organization a load-bearing institution in the long-run health of Bitcoin's developer base. Its second significance is institutional. Beyond education, Chaincode Labs funds Bitcoin research and pays open-source developers, sitting alongside the small set of organizations that sustain protocol development without controlling it. Its educational programs feed the same contributor pipeline its funding supports — a coherent strategy for reproducing the expertise Bitcoin's development depends on (see [Developer funding and incentives](https://timechain.wiki/wiki/developer-funding-and-incentives.md)). --- ## Bibliographic details - **Title:** Chaincode Labs - **URL:** [chaincode.com](https://chaincode.com/) · education: [learning.chaincode.com](https://learning.chaincode.com/) (₿OSS Challenge) - **Location:** New York City - **Mission:** "Chaincode Labs exists to support Bitcoin" — protocol research, developer funding, and contributor education - **Education flagship — the ₿OSS Challenge:** a structured ~3-month journey; Month 1 is a mentored foundation of programming exercises and hands-on activities (async support, ~10 hrs/week); Months 2–3 are an optional advanced phase with partner-organization programs and a seminar - **Teaching model:** Mentored by ₿OSS contributors; curated cohorts - **Pricing:** Program-based; selective cohort admission - **Level:** Advanced - **Bitcoin scope:** Bitcoin protocol and open-source development --- ## How to engage this platform **Where it fits.** Chaincode is the destination for a programmer who has decided to work *on* Bitcoin rather than merely with it. The natural precursors are protocol grounding ([Technical foundations](https://timechain.wiki/wiki/technical-foundations.md), [Bitcoin Core](https://timechain.wiki/wiki/bitcoin-core.md), [Bitcoin Improvement Proposals](https://timechain.wiki/wiki/bitcoin-improvement-proposals.md)) and hands-on protocol practice ([Base58](https://timechain.wiki/wiki/base58.md)); the ₿OSS Challenge then provides the mentored path into actual contribution. **As an ecosystem institution.** For a reader mapping how Bitcoin development sustains itself, Chaincode is a case study in the research-plus-funding-plus-education model — relevant to the governance and developer-funding notes as much as to the education section. --- ## Counter-arguments and tensions **Narrow by design.** The ₿OSS Challenge is not for general learners — it presumes programming ability and substantial time. That specificity is the point (it produces contributors, not literacy), but it means the resource serves a small, self-selected audience rather than the broad on-ramp the introductory platforms provide. **Selective and cohort-bound.** Curated admission and scheduled cohorts limit throughput. This is inherent to mentorship-intensive education; the trade-off for high-touch onboarding is that it cannot scale to everyone who applies. **Funder-in-development question.** Organizations that both fund and train Bitcoin developers occupy a sensitive position in a system that prizes the absence of central control. The KB's own [Developer funding and incentives](https://timechain.wiki/wiki/developer-funding-and-incentives.md) and [Governance without governance](https://timechain.wiki/wiki/governance-without-governance.md) notes treat the general tension; Chaincode's model — funding and education without protocol authority — is broadly regarded as a healthy contribution, but the structural question is worth naming honestly. --- ## Where to find this source - **Chaincode Labs:** [chaincode.com](https://chaincode.com/) - **₿OSS Challenge (education):** [learning.chaincode.com](https://learning.chaincode.com/) ### Place in the broader Bitcoin canon - [Base58](https://timechain.wiki/wiki/base58.md) — a sibling Bitcoin developer-education resource (protocol school / workshops); complementary, different model - [Developer funding and incentives](https://timechain.wiki/wiki/developer-funding-and-incentives.md) — the open-source-sustainability context Chaincode participates in - [Educational websites and online resources](https://timechain.wiki/wiki/educational-websites-and-online-resources.md) — this source's sub-MOC (Technical / developer) --- ## Open questions - How does the ₿OSS Challenge's contributor-conversion rate compare to other developer on-ramps?
