0/ Sybil resistant airdrops have turned into an arms race.
We had no idea what we were up against when we started designing the Hop distribution.
Here’s how we filtered out over 10,000 Sybil attacker addresses and enlisted army of Sybil hunters to find the rest 👇

As some of you know, I’m currently being sued (personally) in a putative class action lawsuit.
I can’t speak about it publicly because the litigation is ongoing but I want to share some context and ask for your help.

Sybil detection for airdrop distribution has two paths:
1) reveal more identity and lower barrier (ie. KYC or @worldcoin)
2) increase barrier to entry by making it more difficult with things like t/x history
What airdrop path will crypto projects take in the next cycle?

Hop is now live on Instadapp!
Users can now easily bridge between chains using @HopProtocol.

The governance channel in @HopProtocol is live, and I am politicking like a mofo.

gm, let’s kick off L2 szn.
We requested to use our 1m $OP tokens to refund 80% of users bridging costs to Optimism.
Hopping made even easier ⚡️

Optimism is for the people, not the sybils.
We’ve been carefully analyzing OP Airdrop #1 for sybil attackers that slipped through the cracks. We’re happy to announce that we’ve removed an additional 17k sybil addresses and recovered over 14 million OP. Bye bye sybils!

trolling salty sybil farmers in Hop discord is my new part-time job.

The Hop Sybil defendooooors are crushing it with so many awesome hunting techniques
Open sourced my code! May do a detailed writeup on my methodology later.
tl;dr I implemented the Union-Find graph algorithm, which finds connected subgraph components in O(1) time.

One of the PayPal cofounders compared our Sybil protection work at Hop to early fraud protection at PayPal and I didn’t even see it 🤦

We (@l2beatcom) just applied to become a @HopProtocol delegate!
Hop is one of the critical pieces of infrastructure for the multi-L2 world. We would love to be a part of that community.

⛽️Lazy Sunday playing around thanks to low gas.
🔴Bridged 0.2 $ETH to @optimismPBC via the @HopProtocol (received tiny bit more than 0.2 ETH)
🐦And then just to show off how modular the new @rotkiapp transaction viewer system is wrote the decoder for it.
Coming soon at v1.24.0

I can't believe I slept on @HopProtocol. I just used it for the first time to transfer Eth from Arbitrum to Polygon for pennies in five minutes. This is freaking magic. Suddenly very excited to dig deeper, even if I am late to the party.
