A look at the ten winning projects of the ETHLisbon Hackathon
Original author: Morty, Deep Tide TechFlow
On October 31st, the Ethereum Lisbon Hackathon came to an end. The hackers sent a total of 97 projects and 352 developers.
Next, this article will give you a quick look at the ten winning projects of this hackathon.
Deterministic Encryption and Storage via Snap and IPFS
(hereinafter referred to as "D")
"D" is an application designed to protect user dApp data in a decentralized manner, with "EIP-5630" at its core. "D" built an app called Metamask Snap that implements "EIP-5630". At the same time, it provides a wallet interface for encrypting and decrypting data using the wallet's private key. The user's data in the dApp will be stored in a decentralized manner through IPFS.
Realms Assassins - Fog of War
Realms Assassins - Fog of War is a data storage protocol for on-chain games launched by BibliothecaDAO. It was built on Starknet to solve the problem of encrypting trusted public information.
The original intention of BibliothecaDAO is to protect the data privacy of players on the chain-these data can only be viewed when certain conditions are met. It likens Fog of War to a trusted third-party "dungeon master" that stores private information and allows players to play multiplayer on-chain games without zk hashing.
SafeCheck
SafeCheck's tagline is "Better insights about your transactions" and it helps users understand the destination address and transaction outcome before sending a transaction.
In essence, SafeCheck lowers the threshold for blockchain participation and is user-friendly for newcomers.
Archive the Web
Archive the Web allows users to set up automatic website archives at predetermined intervals (that is, every 60 minutes) and store them on Arweave. Protocol users need to pay in ETH, ERC-20 or AR.
At the same time, Archive the Web has developed a custom Metamask Snapthat, which allows Metamask to interact directly with Arweave/Bundlr, and users only need to use ETH//ERC20 wallets to interact with Smartweave contracts through the new Warp Ethereum signer.
Use cases for Archive the Web include, but are not limited to:
1) revenue and preservation of digital history;
2) Archive government (historical) websites;
3) Archiving personal or business websites;
4) Archive news reports;
5) Record the real history;
6) Add a layer of data redundancy to the work of the Internet Archive/Retro-Machine by launching a parallel World Web Archive initiative.
Multi Resolver Snap
Multi Resolver Snap is a Snap app that takes over the task of resolver for dApps. With Multi Resolver Snap, users can send cryptocurrency to anything (Twitter name, email, ENS, Lens...) without developers having to bother with integrating multiple resolvers. Multi Resolver Snap aims to make the Web3 world simpler.
Snap-Sync Verkle Trees（VerkleIPFS）
Snap-Sync Verkle Trees attempts to use snapshots of recent blocks for POC and draft retrieval of Verkle Trees through IPFS for faster and sustainable retrieval.
Among them, VerkleIPFS is a proof-of-concept tool that allows the mainnet Verkle Tree to be generated and retrieved in significantly reduced time by using snapshots that are compressed and stored on the IPFS network.
Snap-Sync Verkle Trees aims to use IPFS to solve Ethereum's core development problem: the long Verkle Tree calculation time.
Lekker Finance
Lekker Finance is a decentralized perpetual futures trading tool based on Euler Finance. Lekker Finance allows users to enter leveraged positions on Euler Finance, and by using flash swaps, positions can be opened with only one transaction. Lekker Finance was launched to simplify the process of futures trading.
Zilly - ETH Lisbon
Zilly is an embedded widget that helps brands create a Web3 loyalty program. Through Zilly, brands can use certain activities to increase user engagement and brand loyalty.
Trust Score Snap
The Trust Score Snap helps non-technical users assess how safe it is to interact with smart contracts. It will display a 🟥 🟧 🟩 score, which consists of:
1) The popularity of the smart contract;
2) The interaction frequency between the user wallet and the smart contract;
3) The duration of deployment of the smart contract, etc.
It shows users in a simple way how risky it is to interact with a certain smart contract.
GlacierDAO
GlacierDAO is a decentralized autonomous organization with the goal of preserving open source code as a public good. They believe that code, like data, should be preserved in a way that is resistant to censorship.
