Episode notes
Match SDK To Your Needs
- Pick the SDK implementation that matches your app's trust, latency, and privacy needs.
- Roy advises using multiple Breeze SDKs so partners can choose Greenlight, LDK, Liquid or Spark as appropriate.
Liquid Worked But Had Limits
- Liquid solved product-market fit for some use cases but has trust and minimum amount drawbacks.
- Breeze expanded to Spark to gain unilateral exit, no minimums, and offline receive capabilities.
Spark Is An Evolved Statechain
- Spark is an evolution of statechains with multiple operators and a tree-splitting model to avoid fixed denominations.
- That design enables dynamic change-making and unilateral exits while sharding preimages across operators.
