Chain.Food is the first non-profit Dapp in the Ethereum ecosystem (to solve the problem of food waste). Users can access free food information, publish lists and verify their identities through ERC addresses. Use FoodCoin tokens to incentivize users to receive or donate food. Layer2 tokens can be airdropped rewards through sbt obtained by users. 100% transparency of public welfare funds guaranteed on the chain. Chain Food 是以太坊生态系统中第一个非营利性 Dapp（解决食物浪费问题）。 用户可以通过ERC地址获取免费食品信息、发布列表并验证身份。 使用 FoodCoin 代币来激励用户接收或捐赠食物。 Layer2 代币可以通过用户获得的 SBT 进行空投奖励。 链上保障公益资金 100% 透明度。

We offer unparalleled support for heterogeneous chain arbitrary message cross-chain communication. Utilizing advanced zero-knowledge cryptography, IZAR ensures fully private cross-chain transactions while maintaining robust user privacy and security. Additionally, the protocol is designed to incorporate a novel governance model and zkSnark multisig verification to further enhance its capabilities and user trust. IZAR 是开创性的隐私保护互操作性协议，无缝连接以太坊和 Aleo 生态系统。我们为异构链任意消息的跨链通信提供了全面的支持，打通生态之间的流动性，利用行业领先的零知识密码学技术，实现完全私密的跨链交易。此外，该协议还将引入全新的治理模型（1000 个去中心化验证者）和 zkSnark 多签验证，来解决目前跨连桥的中心化问题，进一步提高跨连桥的安全性和用户信任度。
Lumi Finance serves as an investment platform focused on sustainable wealth preservation. By using LUA as collateral, Lumi Finance provides zero liquidation-risk loans with negative interest rates, allowing borrowers to earn yield on their debt. These loans carry no liquidation risk, as the total LUA debt never surpasses the token's floor value (guaranteed minimum value). Borrowers of LUA do not need to pay ongoing fees to liquidity providers, resulting in negative interest. Lumi Finance 是一个专注于持续财富保值的投资平台。 通过使用 LUA 作为抵押品，Lumi Finance 提供了零清算风险且具有负利率的贷款，使得借款人可以在其债务上获得收益。这些贷款没有清算风险，因为 LUA 总债务永远不会超过代币的底价（保证的最低价值）。LUA 的借款人不需要向流动性提供者支付持续的费用而产生负利息。
BitPoW is a Layer 1 blockchain that is the most innovative in the crypto industry after Bitcoin and Ethereum. The project's team has discovered the first useful PoW algorithm, named EcoPoW, which is the directly upgrade of existing PoW with minimal change. BitPoW allows for almost free gas fees, making it a more affordable and accessible option for users. BitPoW is resistant to mining pools, which is more decentralized than Bitcoin. BitPoW 基于第一个有用的工作量证明。在此革新驱动下，公链可以实现超越比特币的去中心化，移除矿池，并给链用户提供无与伦比的低 gas 成本。于此同时，丝毫不会影响区块链的安全性，也不会鼓励挖矿军备竞赛和贪婪的耗能。
Cellula is a fully on-chain artificial life simulation game. Players explore, cultivate, evolve, and collect unique Life forms in the game. In this game, the rules of Conway's Game of Life are considered the genetic code of the Life forms, determining their forms and vitality. Using the game's crafting table, players can freely create a variety of genetic sequences and give birth to their own on-chain Life forms. These Life forms have unique appearances and properties, and exhibit diverse life forms. Cellula 是一个完全基于区块链的人工生命模拟游戏。玩家在游戏中探索、培育、进化和收集独特的生命形态。在这个游戏中，康威的生命游戏的规则被视为生命形态的基因代码，决定了它们的形态和活力。玩家可以使用游戏的工作台自由地创造各种基因序列，产生他们自己的基于区块链的生命形态。这些生命形态有独特的外观和属性，并展示出多样的生命形态。（by translation software)
Autochessia is a auto chess game like Dota2 auto chess, but built fully on chain, which means not only all states of game are read from and stored in blockchain storage, but also all processes related to game playing are implemented by smart contracts. Believing fully on-chain game would brings the next generation UGC paradigm, we make this game and try to make it extensible. During hackathon, to make this game possible on-chain, we implemented JPS(jump point search) in solidity, designed the game tick, and introduced VRF as true random. Autochessia 是一款自走棋游戏，但完全运行在区块链上，这意味着不仅所有的游戏状态都是从区块链存储中读取和存储的，而且所有与游戏相关的过程都是通过智能合约实现的。 我们相信全链游戏将带来下一代UGC模式，所以我们制作了这款游戏并尝试着让它具有可扩展性。 为了使该游戏能够在链上运行，我们在solidity中实现了JPS(jump point search)，设计了游戏最小间隔，并引入了VRF作为真随机数。
This is a fully on-chain game that combines real-time strategy, looter, and dark forest survival elements. But we are not just play for fun, Emotions brought by AON are not just leisurely, but rather a range of emotions, such as fear, relief, and so on. For an individual player the game map Satosea is covered by the fog of war, and mimcHash is used to encrypt the coordinates. Various resources, artifacts and other players are hidden under the fog. Anyone is free to explore here. 游戏地图是一片被战争迷雾覆盖的 Satosea，使用 mimcHash 对坐标进行加密。迷雾下隐藏着各种资源、神器还有其他玩家。任何人都可以在Satosea 中自由探索。游戏使用 MUD 作为引擎，将 satosea 场景的信息存储在链上智能合约中。随着航行，玩家演算合约上对应参数，战争迷雾会被揭开。玩家使用 POW 算法挖掘地图上的资源，或捡取神器。资源将成为游戏内交易、质押的代币，而神器则可以强化各种游戏表现。所有人之间可以互相攻击，掠夺财产。玩家在执行动作，如挖掘资源或攻击时，会暂时向所有人暴露位置。因此需要隐匿自己的踪迹，获取别人的信息。这其中包含丰富的策略和玩法。
GasLockR uses a ZK coprocessor for historic gas prices, offering real-time, verified pricing models to hedge gas price volatility. As on-chain infra, it builds protocols and services for improved reliability and UX. Integrated with other wallets/services like Account Abstraction, it enables SLAs for users to rely on blockchain transactions. GasLockR's key services are gas insurance, offering a premium for future gas price protection, and gas fee subscription, enabling ERC20 token/fiat to subscribe to Dapps based on transaction count or period. GasLockR 使用 ZK 协处理器来获取历史 Gas 价格，提供实时和可验证的定价模型的衍生品来对冲 Gas 价格波动的风险。作为链上基础设施，它可以构建协议和服务，来提高区块链可靠性和用户体验等问题。我们提出 GasFi 一词，并把GasLockR 作为第一个免信任的 GasFi 衍生品协议。借助 GasLockR，其他钱包或服务如帐户抽象 (ERC-4337) 将能够为其用户提供 SLA，从而让用户和组织依赖区块链生态。基于 GasLockR，我们提供服务包括：可交易的 Gas保险，为未来 Gas 价格提供保费；以及 Gas Fee订阅，用户可以使用 ERC20 代币或法币，根据交易数量或时间周期订阅 Dapp 的交互操作。

EquitySwap provides a new market cap growth model that enables projects always have good liquidity on price rises. It also reduces impermanent loss and trading slippage. For new projects: there is better liquidity even without external adding liquidity. For mainstream coins: impermanent loss is reduced to about one-tenth of Uniswap, users and market makers can get rising profits and 30%-100% annualized returns. Combined with the precise incentive and rebate mechanism, it can gradually replace CEX to achieve the full decentralization of trading. EquitySwap 首创了新的市值增长模型，让项目在价格上涨的过程中始终有较好的流动性，同时能降低无常损失和交易滑点。 对于新上线的项目：在无外界添加流动性的情况下，当项目市值上涨到十万亿美元时，仍然具有较好的流动性。 对于主流币：无偿损失降到 Uniswap 的十分之一左右，用户和做市商质押流动池既可享受到价格上涨的红利，又能享受到 30% - 100% 的年化收益。 新功能搭配精确的激励机制，可以逐步取代 CEX，实现交易的全面去中心化。
