Kaspa on Rust — Mempool-Focused Release (second stable release)
This version focuses on introducing mempool features required for users and wallets for adopting to fee market conditions.
The main mempool features include:
- Replace-By-Fee (RBF)
- A fee estimation API based on real-time mempool state
- A new mempool evict policy based on fee rate
The version also includes the following major changes:
- Major performance enhancements in the block template transaction selection algorithm. This operation now takes only ~100 microseconds even under heavy load, and that is achieved without compromising on the most profitable selection strategy.
- Important improvement in header processing performance
- Many more accumulated enhancements, improvements and non-critical fixes
It is highly recommended that miners and pools gradually shift to this version both for stability reasons and for better supporting the network under upcoming expected fee market conditions.
