mpc, zkps, semaphore... quite complicated system. we made PoC in less than a month. d/acc https://x.com/MikhailDobs/status/1943613762985955353

Looking for feedback on the proposal for privacy-focused sybil resistance solution powered via MPC-TLS and Semaphore zero-knowledge group proofs - https://ethresear.ch/t/privacy-preserving-sybil-resistance-via-mpc-tls-and-semaphore-proofs/22722

About $bring Token:   1/ The Bring token was launched via @clanker on Base in Jan 2025. The goal was to experiment with token distribution and build out a zkTLS-powered airdrop platform.

Introducing technical design for proof of humanity based on online credentials, powered by MPC-TLS (based on @tlsnotary) for private web data authentication and Semaphore inclusion zero knowledge proofs for improved privacy. More details in the draft paper https://github.com/BringID/whitepaper/blob/main/whitepaper.md

Some Bring updates: - we're not releasing the early version we already developed because there are certain trust and privacy assumptions for a 3rd party zkTLS provider we're not comfortable with. - after sharing a testnet version with early users, we discovered that idea of using zkTLS verifications as a proof-of-humanness resonates more than the idea of attracting non-crypto users with targeted airdrops

Some of the key learnings: - crypto power users hesitant to install a 3rd party extension. Updating the design to add more info about why the extension is required for the zkTLS verification and why zkPass can be trusted (500k+ installs, audited & open-source code, backed by legit VCs, etc) - less savvy users don't care that much about this issue (they mainly want to claim tokens) - since we launched the testnet version Reddit has retired the API endpoint we were validating and the zkTLS verificatiion schema no longer works. To mitigate this issue in the future: a. we're adding a way to update the schema for existing drops. b. we will limit timeframe of the drop (e.g. 2 weeks) to lower the chance of API changes within this timeframe

zkBring demo: verify Uber account (at least one trip) and claim tokens. airdrops for real humans, not bots: > zkTLS verification via zkPass > instant gasless onboarding with Coinbase Wallet > token incentives to get onchain launching on Base soon. DM to test!

With zkTLS, any data from any website can become airdrop criteria. The screenshot shows our current airdrops live on Base Sepolia. For Mainnet launch and our first zkTLS airdrop, we're designing criteria that: - are difficult to Sybil - are relevant to most users (at least one per person) - showcase zkTLS's full potential

Launching next week. Anyone wants to test an early version on Base Sepolia and give us your feedback?

Platform polished and ready. Launching soon. Currently finishing the docs and working on our first campaign drops.

How to disable multiple smart contracts to claim the same webproof and allow user to choose an address to claim after proof generation: 1. Create an ephemeral signer 2. XOR drop contract and ephemeral signer addresses 3. Generate webproof attached to the XORed address 4. Let the user create a new wallet and sign the fresh new address with ephemeral signer 5. At claim drop contract computes XOR address, verifies that it's attached to the webproof and verifies that claimer address was signed by ephemeral key initially I came up with hashing two addresses instead of XORing, but @cxrtisxl suggested XORing them instead of hashing and I liked it better.

dev update pt2: Front-end: > @spacehzxmayhem is working day and night on the front-end, rewriting existing parts of the code to NextJS for Server side rendering and all-in-one platform experience - users will be able to launch new drops, see a list of created drops by other users and claim a drop, all within a single app. > We will use Privy for wallet authentication. Familiar for crypto native users and have an option to sign up with email for newbies (creating a Coinbase Smart Wallet under the hood)

dev update: > as shared before, we decided to launch with zkPass and desktop-only version. The reason is that we found that a browser extension is the best UX for zkTLS proof generation: - you don’t have to enter sensitive credentials into a random app. - proof generation is both reliable and fast with zkPass > last couple weeks @noisebody0x and I spent a lot of time iterating on the drop page. We realized that we're one of the first teams working on a zkTLS user-facing product and we don't have a visual language to showcase the privacy benefits of zkTLS (similar to the private tab icon / HTTPS lock icon in browsers). So, we used a simple familiar structure for the functional part of the page (do something and get tokens) and intentionally decided to confuse users with unknown technical concepts like "Verify via zkTLS" and "Generate webproof" to educate them about the new tech. TBH i like what we got in the end. What do you think?

dev update: > been quiet for the last couple weeks as we're busy working on the platform > decided to go fully desktop for the launch as we've discovered that the zkTLS xp is much nicer on desktop (check out zkpass) > launcher is ready, working on the platform now > expect couple more quiet weeks as the team full-mode building > really excited about the upcoming launch 😎

re: onchain reputation: We will add SBT support to Bring. Generate zkTLS webproof of any internet data (e.g. that you've played N hours on Steam) and claim a corresponding SBT. Now you have a way to target Steam players onchain. https://x.com/JayLovesPotato/status/1894726519077138872

going to @base HK meetup today? dm and meet me to chat about zkTLS webproofs. bonus: I'll help you generate a Luma webproof that you're attending the event to get some bring

1/ discussed with @noisebody0x what zkTLS webproof to add to our airdrop launcher at first. we want it to be such that it covers a use case relevant for many people / projects.
