Proposal: Dual-Key Stealth Address Protocol

[wuyahuang]

Project Abstract

Public ledgers are generally seen as “pseudo-anonymous” as addresses can be linked to one person although that person’s identity is unknown to the public. However, by combining this info with other data it is possible to discover the real world identity behind the address. Many individuals and companies prefer to have an additional layer of security in order to keep their privacy. That’s where DKSAP come to play.

I think DKSAP support is potentially interesting, but would like more detail on what exactly you are proposing (see comments) before approving.

Hi @Noc2 , Thanks for you feedback. I have already updated file. Please check this.

[Noc2]

Thanks for the application. I’m happy to support the application. I have just one question: where can I find the solidity implementation?

[wuyahuang]

Hi, @Noc2 . Thank you for your affirmation and encouragement. The DKSAP has been implemented in a number of cryptocurrency systems, including Monero, Samourai Wallet, and TokenPay. I'm afraid there is not a solidity implementation of DKSAP yet, but if polkadot ecosystems likes it, I'm happy to develop implementation for solidity. 😄

[Noc2]

Ah, I was referring to this: “After the Solidity implementation of DKSAP is fully tested”... but you probably meant “after the ink! Implementation”. In any case, we prefer the ink! Implementation, but you potentially can apply for solidity implementation here: https://moonbeam.foundation/grants/

[wuyahuang]

Oops. That's a typo. I have already updated it. I'm happy to apply for solidity implemention after this GRANT delivered.

[laboon]

Thanks for the updates @wuyahuang , I am happy to approve now.

[wuyahuang]

Thanks for your approvals @Noc2 @laboon , I'm looking forward to delivering DKSAP implementation to the Polkadot community in 6 weeks, and can't wait to see positive results.
