Supporting this proposal means you agree that, Kusama implements an independent JAM upgrade with a lightweight, non-standard configuration designed for its economic constraints.
Like Polkadot did with ref#682, it's time for Kusama to take a stance towards JAM. The problem is, the costs of running a full JAM instance are too high for Kusama's small economy, so we either run a smaller instance(optimized for new use cases with 1sec finality) or hope for Polkadot to agree to share the same instance to split the cost between the 2 economies(Opt.B)
Configuration
- 32 cores (vs. Polkadot's 341)
- 1-second block time for very low latency
- KSM as native token for all economic functions (storage, staking, coretime)
Economics
With a greatly reduced core count and validator set the network can lower its security costs dramatically(~2.4% KSM inflation worst case), other mechanisms like Proof of Personhood can be consider to reduce further costs and make it manageable for Kusama's low cap economy.
Trade-offs
Benefits:
- Fast finality is great for real-time applications
- Cost-effective and economically sustainable
- Maintains full independence
Limitations:
- Lower throughput than full JAM
- Reduced internal data transfer capacity
Strategic Value
- Preserves Kusama's experimental nature in JAM era
- Creates unique positioning on latency/throughput spectrum
- Establishes Kusama as the platform for latency-sensitive applications
