Introduction

The JAM initiative represents one of the most ambitious undertakings in the Polkadot ecosystem. Many independent teams have invested over a year of work into implementing clients, tooling, and research based on the evolving Graypaper. However, recent economic and structural changes raise real concerns about the sustainability and continuity of this effort.

This post aims to open an ecosystem-wide discussion on whether Polkadot should introduce a dedicated JAM funding scheme (e.g., a JAM Bounty or JAM Working Group) to support ongoing development outside the narrow boundaries of the JAM Prize.

1. Economic Context Shifted Dramatically

The intention here is not to debate market prices — they fluctuate — but to acknowledge that funding mechanisms designed under one set of assumptions may no longer match the reality teams are operating in.

When the JAM Prize was announced:

DOT was ~$5

A milestone payment of 100k DOT ≈ $500k

Today:

DOT is ~$2

The same milestone now represents ~$200k

This means prize funding has effectively shrunk by 60%, while expectations and required work have not changed. For full-time teams, this massively increases the risk profile of participating in JAM. To put this into perspective: the current ~$200k equivalent per milestone does not even cover the cost of two senior blockchain engineers working full-time for 18–20 months. Many teams have already exceeded this level of effort, effectively self-funding substantial development time with no guaranteed payout.

2. Timelines Have Drifted – Increasing the Burden on Teams

Several expectations set early in the process have not materialized:

2.1 JAM Prize Submissions (M1)

Initial ecosystem discussions suggested a rough timeline of around one year for early M1 progress, but the evolving complexity of the protocol and lack of a formal submission guidance means teams cannot confidently plan long-term development,

Many teams have now been building for 20 months,

Yet no M1 submission process or timeline has been announced.

This lack of clarity makes coordinated progress difficult across dozens of independent teams and may unintentionally disincentivize long-term investment into JAM.

2.2 Graypaper Stability

Current Graypaper is v0.7.2, nearing v1.0 but progressing slower than initially expected.

Every change requires teams to refactor large parts of their implementation.

This adds recurring engineering overhead that teams must continuously absorb as the protocol evolves.

3. The Actual Number of Actively Conformant Teams Is Smaller Than Expected

This is not a criticism of teams — it is a reflection of the reality that without predictable support, fewer teams can justify maintaining full conformance.

Of the 43 “self-announced” JAM teams listed on graypaper.com:

Only 10 are conformant with GP v0.7.2

Another 4 are still on v0.7.1

Total actively updated & conformant teams: 14

This suggests the ecosystem is already experiencing dropout, which is expected when teams must choose between unpaid JAM work and paid work elsewhere.

4. The Chicken-and-Egg Problem of Funding

Teams need long-term funding to:

Work full-time on their clients

Build tooling (SDKs, profilers, debuggers, fuzzing frameworks, networking tools)

Reach M1 and beyond

Support future JAM services developers

However:

Without M1-ready clients, no funding is flowing.

Without predictable support mechanisms, only a small subset of teams can justify allocating full-time resources to JAM for long periods. This slows collective progress toward M1.

This circular dependency threatens the entire decentralization and multi-implementation vision of JAM.

Parity alone cannot—and should not—be the only team able to sustain full-time JAM development.

5. Downstream Ecosystem Impact

This is about enabling the broader developer ecosystem — not just protocol implementers — to build confidently on JAM.

The Polkadot Blockchain Academy (PBA) announced a JAM-focused course for March 2026.
They planned:

A mature JAM testnet

A stable JAM SDK

Fully working clients

Hands-on materials for JAM service developers

If independent client teams cannot sustain their work, the entire downstream developer ecosystem (courses, tooling, service builders) risks stalling.

6. Proposal for Discussion: A JAM Bounty Program

To break the deadlock, we could consider creating a JAM Bounty (or JAM Working Group) funded via OpenGov, with the following goals:

6.1 Funding Scope

Support areas not covered by the JAM Prize, such as:

Tooling (profilers, fuzzers, analyzers, test harnesses)

Developer experience (SDKs, libraries, templates)

Documentation, education, course material

Reference implementations of key JAM components

Testing infrastructure (clusters, CI systems, conformance tooling)

Research into performance, networking, and security

6.2 Governance Model

A small technical committee (e.g., 5–7 members):

Selected by OpenGov or via a transparent application process

Responsible for reviewing proposals and allocating micro-grants/bounties

Reporting periodic outcomes to the community

6.3 Funding Amount

Enough DOT to:

Support multiple teams simultaneously

Provide predictable multi-month development runway

Reduce dropout risk

The exact amount should be calibrated during this community discussion.

7. Key Questions for the Community

1. Should Polkadot create a long-term funding mechanism dedicated to JAM development?

2. Is a JAM Bounty the right structure, or should we explore something like a JAM Fellowship or Working Group?

3. How do we preserve decentralization and avoid a future where only Parity has a fully functioning JAM client?

4. What level of DOT funding is appropriate given the current market conditions?

5. How can we better align incentives between prize timelines, Graypaper evolution, and team sustainability?

8. We Cannot Ignore Market Momentum

This is not about rushing JAM — correctness is paramount — but about ensuring that the teams building it have enough runway to maintain momentum while competitors continue shipping.

While we’ve been building JAM for 20 months, the broader blockchain ecosystem has not stood still. Competing platforms continue to:

Ship new developer environments

Launch scalable execution layers

Improve smart contract tooling

Attract capital and talent through aggressive funding programs

Polkadot’s technology is exceptional—arguably best-in-class for deterministic distributed compute. But technology alone is not enough.

In fast-moving markets, time-to-market becomes a competitive moat.

If JAM takes too long to reach a production-ready state, we risk:

Losing mindshare to ecosystems that move faster

Losing developers who need real environments to build on today

Losing investors and partners who follow visible momentum

Becoming technologically “correct” but strategically irrelevant

This is not a theoretical risk. The history of technology is full of examples where the best architecture did not win—because it shipped too late.

A modest acceleration now, through targeted funding of critical teams, could mean the difference between:

JAM launching into a strong, growing market, versus

JAM launching into a future where competitors already captured the narrative and developer base.

Polkadot is at an inflection point. The ecosystem has a brief window to transform JAM from an experimental initiative into a real, live system with developer adoption. The market momentum is real, and we should not underestimate its impact.

A dedicated JAM funding scheme would not just help teams survive—it would help Polkadot win.

Conclusion

This discussion is not about any individual team’s needs — it is about ensuring Polkadot maintains a diverse, resilient, and competitive JAM ecosystem.

JAM is a once-in-a-generation opportunity to redefine decentralized compute.
But without sustainable funding, we risk losing teams, momentum, and the multi-client resilience that has always been a core value of Polkadot.

This post is not a complaint—it’s an attempt to spark constructive discussion on how we can support JAM builders today so that the ecosystem can thrive tomorrow.

I welcome feedback, alternative ideas, criticism, and of course: collaboration.
