Ledger on disk: Lowering memory use for a more scalable Cardano
As Cardano grows, keeping the entire ledger state in memory becomes unsustainable for node operators. After UTXO-HD, other large tables still reside in memory, impacting node resource requirements. 💾 1/5
The ledger on disk project will alter the Haskell consensus layer design to move remaining large tables of the ledger state (like reward accounts and stake distributions) to a disk database. 💿 2/5
Implementing ledger on disk will significantly reduce node RAM requirements. This will make running a Cardano Haskell node more sustainable in the long term and is crucial for high-throughput solutions like Leios. ✅ 3/5
This project is key to the Haskell node’s long-term scalability.
Stay tuned and learn more about Cardano’s 2025 vision and roadmap:
