The $BUNK testnet

Crank a real sequential-squaring Verifiable Delay Function in your browser, seal a block, and broadcast the proof. The network re-verifies every proof server-side before appending it to a shared, persistent chain.

Crank a $BUNK block

Hold the crank. Each turn runs 3,000 sequential VDF squarings. Seal 60,000 to mine a block, then broadcast the verified proof to the live chain.

Testnet only. This is an experimental proof-of-concept. No real funds, no token of value, no value transfers. Blocks are VDF proofs verified by the network and stored on a shared testnet ledger for demonstration purposes.

What just happened

The proof pipeline

Seed from entropy

A SHA-256 seed x is drawn. This is the input to the VDF.

Crank = squarings

Each crank pulse computes y = x^(2^t) mod N — sequential, non-parallelizable work. You can't skip ahead.

Verify locally

The output is re-derived from the seed to prove it's honest before anything is broadcast.

Broadcast & append

The proof is re-verified server-side, then appended to the shared chain — a permanent, inspectable ledger entry.
