It's been more than a week since ETHCC and ETHGlobal Paris, and we had to write up a quick retro before more time passed and the next hackathon began! In Paris we had a chance to connect with many projects interested in incorporating crypto privacy into their applications, as well as catch up with old friends and meet a bunch of new ones. The hackathon was a success, and we look forward to seeing additional developments from projects that successfully built with zkBob.
ETHCC: Privacy and Compliance
ETHCC started out with a morning presentation on incorporating compliance into privacy applications. Privacy and compliance need to work together, and Andrew went over several ways privacy projects can begin to incorporate compliance without sacrificing individual privacy on-chain with the use of zero-knowledge technology.
We spent the rest of the week attending presentations and meeting with prominent members of the community throughout Paris. This year there were tons of side events and 2 venues for the main event, and the vibe was all about building and bringing on the next wave of users.
ETHGlobal: Integrating privacy-enhanced wallets
On the heels of ETCC, the ETHGlobal hackathon welcomed 1400+ attendees. Kirill presented a workshop on integrating zkBob as a privacy-enhanced smart contract wallet to get things started.
The zkBob booth was busy as usual, and shirts and bags went quickly to interested attendees. We answered a lot of hacker's questions about privacy and how to incorporate zkBob into their private workflows.
Buidling privacy with zkBob
We had a number of amazing projects integrate with zkBob and use the new client library SDK to improve privacy in their applications. In the end, three winners were chosen for their unique use cases and usage of the zkBob protocol.
1) zkFundMe $3K
zkFundMe created an elegant solution for private donations. The UI was easy and clean and allows anyone to create a campaign and receive donations quickly and easily with zkBob.
2) Cypher Deposit $2K
The team behind Cypher Deposit was a previous zkBob hackathon winner (Alice's Ring) and they used the new SDK to create a fully-functional prototype for private withdrawals from exchanges. The team was also featured as a 🏆 ETHGlobal Paris 2023 Finalist and presented in the closing ceremonies, showing all attendees the power of zkBob and private crypto transactions.
3) Wallet Hopper $1K
Wallet Hopper is a unique address mapping application which lets users describe which assets they want to receive to potential senders. zkBob was integrated into the solution for users who request to receive assets privately.
General Prize Pool $4K
In addition to the 3 best projects, a number of projects created zkBob accounts and explored the protocol, earning a share of the the 4K general prize pool. This pool was split between Edu Lend, NFT Together, ProofOfHack, Sybil Resistance DAO, Flora App, Wass Pay, Habitrac, ZKAplha, Checque DeFi, ZKChat and Pay.
We're looking forward to the next hackathon which is the virtual ETHOnline hackathon from October 6 – 27, 2023. This hackathon is longer and open to everyone around the world, regardless of your location. If you are interested, please consider applying and hacking on zkBob!
