Flagship build
Subtick, a blockless distributed ledger, built from scratch in Rust.
- Ed25519-signed transactions execute in ~130 ms, no blocks, no batching, no waiting.
- Sharded executor over real DAG batches, secured by a fault-tolerant 3-of-4 validator quorum.
- Live state streamed over WebSocket · JS + Python SDKs · open-core.
Designed, built & operated solo.
Subtick is open to strategic investment.
