Private transactions
Confidential commitments, range proofs, stealth-style outputs and one-time ownership keys are built into the accounting model.
PRIVATE STATE · DURABLE ANCHOR
Money can be private
without forgetting where safety is.
Midwimble is a MimbleWimble-inspired privacy chain that periodically anchors its state into Midstate — creating durable checkpoints for recovery, finality and eventually anchored cut-through.
Research devnet · Rust · not for real value
Most blockchains preserve every payment as archaeology.
Midwimble starts from a different premise.
Money should be private by default.
TWO RIVERS
One flows. One remembers.
Midwimble handles private economic activity. Midstate provides an external, post-quantum-oriented cryptographic memory.
MIDSTATE
MIDWIMBLE
Midstate anchors
Midwimble checkpoints can be committed into Midstate explicitly or through merged mining, without turning Midstate into a privacy chain.
Dormant recovery
Outputs can carry hidden hash-based recovery commitments that remain unused unless a future cryptographic catastrophe requires migration.
Anchored cut-through
The planned pruning model uses finalized Midstate checkpoints as horizons below which old spent history can eventually disappear.
WHY ANCHOR?
A place to return to.
If the cryptography protecting Midwimble ever becomes unsafe, an externally recorded checkpoint gives the network a deterministic candidate state from before the break.
The anchor does not expose who paid whom. It records only enough to say:
This state existed.

CURRENT STATUS
Working code, unfinished protocol.
Midwimble is research software. The interesting parts are implemented far enough to test, break and improve — not to pretend the work is done.

Private present.
Durable past.
Midwimble is an experiment in building a privacy chain that knows what to do when cryptography changes.
