What’s live today: StableBFT consensus, Stable EVM (full EVM compatibility), StableDB, and the split-path RPC layer are all production-ready. Autobahn (DAG-based consensus) and StableVM++ (optimistic parallel execution) are roadmap items. See the Roadmap for timelines.
StableBFT
Status: Live Stable Blockchain leverages StableBFT, a customized PoS consensus protocol built on CometBFT, for high throughput, low latency, and strong reliability across the network.Planned: DAG-based Autobahn consensus with decoupled data dissemination. See the Roadmap.
Stable EVM
Status: Live Stable EVM is Stable’s Ethereum-compatible execution layer. Standard Ethereum tools and wallets interact with the chain unchanged. A set of precompiles bridges Stable EVM to the Stable SDK, letting EVM smart contracts call into core chain logic atomically.Planned: StableVM++ with optimistic parallel execution (Block-STM). See the Roadmap.
StableDB
Status: Live Stable fixes a major blockchain bottleneck: slow disk storage after each block. It separates state commitment from storage so blocks process without delay.MemDB and VersionDB, powered by mmap, keep recent data in memory while older data is stored efficiently, boosting overall throughput.
High performance RPC
Status: Live A slow RPC layer ruins the user experience even on a fast chain. Stable addresses this with a split-path architecture that separates operations by function, deploying lightweight, specialized RPC nodes for faster response times.Planned: RPC nodes optimized for EVM view calls, plus a node-integrated indexer. See the Roadmap.
