Private Transfers of DOT

inMedium Spender

Executed

This is a retroactive treasury spend proposal by Integritee AG

We ask the treasury for 87'377 USD = 11'655 DOT

Work done:

  • Implement Incognitee Sidechain which can transfer a relaychain native token privately by shielding it to L2 and eventually unshielding it back to the relay chain without linkability
  • Demo Video where we shield DOT from a local Asset Hub to Incognitee and back
  • We are now able to transfer ROC privately (on public Rococo testnet)

Next Steps:

  • launch a public test campaign and bug bounty on our Rococo testnet which we launched in Dec 2023
  • Support for Asset Hub and its fungible assets, i.e. USDC/USDT
  • Support for ANY substrate based chain and its assets

Some History:

edit:

You can now test our tech on our Rococo testnet

First off I want to say it's great that the dotsama ecosystem gets more privacy friendly ways to store and send dot.

Questions:

  • Manta is another player in the privacy field here. With mantas zkassets coming to dot, allowing what I interpret as achieving the same outcome where a users can not find source and destination. What are the main differences in your approach Vs manta?

  • What are the pros and cons compared to what your suggesting?

Thanks

@Rust Syndicate Manta and Integritee chose different technical approaches to the same problem. Manta applies zero-knowledge cryptography while Integritee applies trusted execution environments. We believe privacy is an underserved topic in Polkadot and we should welcome a plurality of approaches

From a user experience perspective:

Manta (Calamari today)

  1. obtain KMA tokens
  2. bring tokens you want to protect to Calamari parachain via XCM (still a tricky endeavour, unfortunately, and only few tokens supported)
  3. shield token to zkAddress
  4. sync chain in browser extension to lookup your balance privately
  5. transfer privately (12s block time)

Incognitee

  1. send your DOT to vault address (no XCM needed) 
  2. transfer DOT privately on Incognitee (1s blocktime)

Notes:

  • Users don't need TEER tokens in the process (which is one of the reasons we think Incognitee will mainly boost DOT valuation and why we think the treasury should contribute to its development)
  • Any parachain could deploy Incognitee on their chain to get privacy for their tokens (another reason why this tech is a common good)
  • In the future, Incognitee can host EVM/WASM private smart contracts (see our PoC) Please remember: Manta promotes zkEVM but that is not about privacy its only about succincness/scalability
  • Incognitee is an L2 to every substrate based chain (even without the consent/support of the underlying L1)
  • Incognitee has a good chance for regulatory compliance because with TEE it can tune selective law enforcement access based on decentrlaized governance. ZK can't do that
  • In order to use Manta for privacy, you need to use their custom wallet UI (or browser extension). Incognitee, on the other hand, can be supported by any substrate-compatible wallet UI easily because it just uses secure websocket RPC.

This is one of the teams with the greatest potential. Excellent work by Alain and his team.
