Contribute to research
Read our published briefs. Find a gap. Write analysis, run experiments, publish findings. All research is open — your name goes on what you publish. Build a portfolio of cited work.
Open research collective — est. 2015
Contribute. Learn. Earn.
kcolbchain is an open blockchain research and developer collective. We publish research, ship open-source tools, and work on hard problems across protocol design, security, DeFi, ZK, and AI x blockchain. Anyone can contribute; sustained contributors can be invited to deeper paid research and partner work.
Build open-source tools
Pick up a good-first-issue on any kcolbchain repo. Ship a PR, get reviewed by the core team.
After a few merged PRs, you're a recognized contributor with a clearer path to funded work and collaboration.

Earn through the network
Recognized contributors may be invited to: paid research and partner projects, grant-funded work when available, contract referrals, and full-time intros—see our contribution policy for what we promise (and what we don't).
What unlocks after your first merged PR
Tiers are derived from public merged-PR counts and rebuilt daily. They're a signal — not a contract. See the contribution & incentives policy §4a.
- Newcomer (1 merged PR) — listed on the public contributors directory (opt-out via
data/contributors-optout.txt); eligible for the contributor Telegram. - Regular (2–4 merged PRs) — we actively @-mention you on issues in the areas you've already touched; easier path onto larger PRs.
- Fellow (5+ merged PRs) — first-invite pool for paid research, partner-org engagements, and grant-funded milestones. Invitation is still by fit, and kcolbchain is not obligated to offer paid work.
@kcolbchain.comemails remain for internal team + partner-project hires only.
Concrete places to start: open invitations board — refreshed daily from every repo.
How earning works
Multiple paths from contribution to income — pick what fits your time and skills. We do not run a standing paid bounty on every issue until we publish amounts and rules; see the org contribution policy.
01
Contribute in public (foundation)
Open issues and PRs on kcolbchain repos—start with good-first-issue and help wanted. Work is unpaid unless an issue explicitly states payment or links to a published bounty policy. We may add paid bounties org-wide later with clear amounts; we may also give occasional discretionary thank-yous.
02
Paid research & partner work — by invitation
Sustained, reliable contributors may be invited to paid research, collaboration with partner projects, and scoped stipends—separate from drive-by OSS, usually with clear deliverables and sometimes contracts or institutional paperwork. This is how we build the inner circle; it is not guaranteed for every contributor.
03
Grant-funded work — project-based
When we secure ecosystem grants (Ethereum Foundation, Arbitrum, Optimism, etc.), we allocate work to contributors for deliverables — research, code, documentation. Typical project sizes are often in the low thousands to tens of thousands of dollars; availability varies by grant cycle.
04
Contract work — recurring
Partner companies need blockchain developers. We sometimes match recognized contributors to contract work — security reviews, protocol engineering, tooling. Rates depend on skill and domain; not every contributor is matched.
05
Full-time placement — long-term
Some contributors get referred to full-time roles at funded blockchain companies in our network. We handle the intro — you handle the interview. No fees to contributors.
