We don't measure success in attendance. We measure it in merged PRs.
A coding school is only as good as what its graduates ship. Here is exactly what the Code Orange community has contributed to Bitcoin open source — and every single number links to a public, auditable record on GitHub. No vanity metrics.

Where graduates go next
The cohort is the on-ramp, not the destination. Graduates plug into the broader Bitcoin developer ecosystem — grants, incubators, hackathons, and full-time roles.
Chaincode Labs
BOSS Challenge — cohort grads enter with priority support
OpenSats
Grant applications for full-time OSS contribution
Bitshala
Protocol incubator — silent-pay & LN cohorts
BTC++ Hackathons
BINST (Taproot + PSBT + ZK) — hackathon finalist
Full-time roles
Bitcoin companies & open source maintainer tracks
Every number here is auditable
We track outcomes in public so funders, partners, and prospective students can verify them independently. No marketing math — just the raw record.
Fund the pipeline, not the overhead.
Code Orange is grant- and donation-funded, and runs lean from Bali. Every dollar turns curious developers across Southeast Asia into merged Bitcoin open source contributors. Support us directly in sats, or reach out about partnership and grant collaboration.
