SIWORLD

Who · How much · When — built so nobody knows.

Status: research prototype. A single-node devnet with mock proofs and low-difficulty proof of work. Not for real funds.

who, how much and when are all hidden

On siworld, no on-chain signal changes with activity from block to block.

Not there yet: nodes that relay a transaction see its fee tier (a leak the design accepts), the miner knows which of its own slots are filler, and Dandelion++, which hides where a payment is sent from, is not built.

03 / Container

Every block
is a full container.

  • Every block carries N = 32 identical-looking packages; one short and it is invalid
  • Every slot is fixed 2-in / 2-out with fixed-length fields
  • Real payments, wallet self-sends and miner dummies are indistinguishable on chain
  • Sealed in strict ascending BLAKE3 slot-hash order
  • Fees and the miner's reward are summed inside the proof and paid as one package encrypted to the miner — never published per block

04 / Packages

Every transaction
happens inside one package.
Nobody knows which one.

01

Commitment

Bound when the package is created
cm = Poseidon2(n)
Appended to the commitment tree
Reveals nothing

02

Nullifier

Revealed only when spent
Unique to each package
Unlinkable to its commitment

03

Ciphertext

Encrypted to the recipient
with post-quantum ML-KEM
plus a 1-byte view tag

  • Value exists only as encrypted packages
  • Every package is the same size on chain
  • Every non-zero package holds at least 0.0001 SIP

05 / Time

Hide time, and prove it.

Sequential BLAKE3 proof of work builds a block-height clock that cannot be turned back

Seal anything as a commitment now, reveal it later to prove it was fixed before block H

Time capsule: claimable only after time T

06 / Tech

Tech stack

Proof system
Hash-based STARK, no SNARK wrapper at the final layer
Hashing
In-circuit: Poseidon2 · Out-of-circuit: BLAKE3
Encryption & signatures
Post-quantum ML-KEM for encryption · ML-DSA for pre-confirmation signatures
Consensus
Sequential BLAKE3 PoW, 60 s blocks at launch
Payments
Under 10 s (payment channels + fast pre-confirmation + containers)
Implementation
Rust · libp2p · redb; any device can take part
