Relational archive, no UTXO database
Packed transactions, spend annotations, and a transaction index in map-free Class A/C tables. Confirm and mempool prevouts read the archive—not a mutable coins bag and not a multi‑GiB dbcache flush.
Experimental 0.x · mainnet is reckless
Bitcoin full node in Rust for server-side operators
A validating peer with a compact relational archive—not a UTXO database—in one Linux-first binary. Electrum, Esplora, and a Core-class JSON-RPC subset are optional. Mainnet use is reckless; consensus divergence is likely.
Why this node is different
One binary and one archive: a validating node without a separate indexer process. Scripthash indexing is optional and billed as extra disk, not as a default.
Wallet indexes when you want them
Electrum and optional Esplora live in-process. They need
--shindex—a selectable indexing cost (Class B scripthash,
extra disk). Off by default. Without it, those listeners refuse to start. Not a
graphical explorer.
Scripts in Rust · modest RAM
Structure, connect, and script verification in-tree on rust-bitcoin. secp256k1 is the only crypto primitive—no libbitcoinconsensus dual-eval. Confirm is lookup → load → scripts → write.
Optional Core-class JSON-RPC
A documented subset over HTTP (--rpc-listen, cookie or user/pass). Chain,
mempool, raw tx, and estimatesmartfee—not wallet, mining, or a UTXO-set
scanner. Prefer Electrum/Esplora with --shindex for script history.
Operator-order facts
Approximate figures from a real mainnet archive. The tip moves. These are order of magnitude, not a warranty.
~886 GiB
Full archive with transaction index
Scripthash is extra if you enable --shindex
< ~30 h
IBD on a laptop-class host
With --milestone 0 (full script checks)
Modest RAM
During sync—no multi‑GiB dbcache
Confirm: lookup → load → scripts → write
Newer transactions resolve hottest in segmented tx.head. A Nix musl build
produces a static binary for ordinary Linux without a matching glibc; there is no
published release tarball yet.

Who it is for
Aimed at operators who validate, store, and serve. The product is not a full Bitcoin Core replacement and not a pruned or desktop node.
Built for
- Operators who want Electrum or Esplora in the same process (with --shindex)
- Infrastructure that needs a documented JSON-RPC subset next to the archive
- Linux hosts with terabyte-class disk for a full archive
- Engineers who want scripts verified in-tree, in Rust
Out of scope
- Desktop wallets, mining, or a graphical UI
- Pruned or low-disk “lite” deployments
- Graphical block explorers and catalogue-style search
Start on signet
Mainnet use is reckless; consensus divergence is likely. Format and APIs stay unstable until 1.0. Source is on GitHub. Build a static musl binary with Nix; release artifacts are not published yet.
