<h2>Saturday July 9th </h2><h2>11:00 Brief introduction to Neon EVM</h2><h3>Konstantin Goldstein - COO - <a href="https://neon-labs.org/" target="_blank">Neon Labs</a></h3> - Why EVM on non-EVM? - How Neon built it. - What properties/features should it build for? - Roadmap and blockers. - What we've learned about user/developer experience. - The opportunities for the EVM and its community. - How Neon Labs can help you. <h2>11:30 Introducing Azuro’s Liquidity Tree: A New Liquidity Pool Design for Specialized Prediction Markets</h2><h3>Dan Kaizer - CTO, <a href="https://azuro.org/" target="_blank">Azuro DAO</a></h3> Imagine if each swap on Uniswap took say 10 blocks, and LPs can put money after the swap has started — it would mean some LPs could cheat and realize gains without any impermanent loss!These were tough problems to solve which required a proprietary solution. A new liquidity pool design, which we called the Liquidity Tree (or LT).Azuro aims to allow any LPs to provide liquidity to the pool and get exposed to all betting markets happening on the protocol, thus reducing the risk for LPs dramatically and leading to a consistent APY. All the while utilizing all that money efficiently for seeding initial liquidity behind thousands of betting markets. More details about Azuro’s Liquidity Tree <a href="https://azuroprotocol.medium.com/introducing-azuros-liquidity-tree-a-new-liquidity-pool-design-for-specialized-prediction-markets-625d68be4727" target="_blank">here</a>. <h2> </h2><h2>12:00 MachineFi </h2><h3>Simone Romano - Developers Community Growth - <a href="https://iotex.io/" target="_blank">IoTeX</a></h3> MachineFi is a new paradigm fueled by Web3 that underpins the new machine economy, wherebymachine resources and intelligence can be financialized to deliver value and ownership to the people.  This workshop will demonstrate how to design and deploy the fundamental  3 components of a MachineFi application, from verifiable real-world data to Web3 tokenomics:1. Smart Devices / Machines that generate data.2. An off-chain, Layer-2 compute network that verifies, stores and generates "Proofs" of real-world facts on top of the data.3. An on-chain, Layer-1 set of contracts that manages authorizations and the token economy based on real-world facts. MachineFi is revolutionary because it has the power to put users in control of the data generated by their devices. By extracting verifiable data from a machine you own, and then tokenizing that data, any user can benefit from the global machine economy. IoTeX is the leading decentralized network powering the future of web3 and machine economy (MachineFi). The platform is built for developers to connect billions of machines with web3 infrastructure, to create innovative products including DeFi, NFT, DAO, Metaverse, and MachineFi applications. Founded in 2017 with a team of alumni from Google, Facebook, Uber, Bosch, and Intel, IoTeX has launched a high-performance public blockchain with off-chain computing for devices and machines, cross-chain bridges, wallet, and the MachineFi marketplace. The IoTeX network has grown rapidly with &gt;$2B in assets on-chain, &gt;300K on-chain users, and &gt;10k devices connected across hundreds of dapps. <h2>12:30 Building successful projects on hackathons: how 1inch was created </h2><h3>Nick Kozlov, Backend Team Lead - <a href="https://1inch.io/" target="_blank">1inch Network</a> </h3> How to prepare to the hackathon, task planning, sharing experience, 1inch swap api and limit order api

<h2>1inch Challenges List </h2>For more info: <a href="https://app.1inch.io/" target="_blank">https://app.1inch.io/ </a> <h2>🏆 NFT Marketplace on the 1inch Limit Order Protocol</h2> Build a marketplace on which users could sell NFTs for any tokens, using the 1inch Limit Order Protocol. Alternatively, you can build an NFT auction based on the 1inch Limit Order Protocol.  <h2>🏆 NFT Aggregator</h2> Build your own Unicorn project from the scratch. Build it on top of the 1inch Aggregator or 1inch Limit Order Protocol for the most efficiency or feel free to create your own product.  <h2>🏆 Margin trading on the 1inch Limit Order Protocol</h2> Write a smart contract enabling the creation of limit orders for margin trading on the 1inch Limit Order Protocol.  <h2>🏆 Margin trading using the 1inch Aggregation API</h2> Build an interface and smart contracts for margin trading using the 1inch Aggregation API. The 1inch Aggregation API has been successfully used in a range of projects, including MetaMask, Coinbase Wallet, Gnosis and Ledger.  <h2>🏆  Automated market making strategy for stablecoins using the 1inch Limit Order Protocol</h2> Write a smart contract that creates buy/sell orders for stablecoins. The idea is to be able to buy stablecoins at lower rates and sell at higher rates, making a profit on rate differences. A smart contract would simultaneously create buy and sell orders.  <h2>🏆  Open Track</h2> Suggest your own solution, keeping in mind that the 1inch Limit Order Protocol has conditional execution and arbitrary price discovery.
