混合型智能合约助力再生农业发展,逆转全球气候变化

从天气指数到物联网传感器数据,越来越多数据不断涌入区块链网络,全世界各地的用户逐渐感受到区块链应用的功能已远远超出货币和金融范畴。如今,在环保领域出现了一种创新的解决方案,帮助全球各国社会共同激励环保举措并直接验证其效果。这种解决方案就是混合型智能合约,这是一种利用区块链基础架构以及链下数据和计算资源的智能合约。混合型智能合约目前已经开始应用于“再生农业”领域,不仅可以有效缓解还可以逆转气候变化所带来的影响,并赋能当地社区。 使用混合型智能合约激励环保举措和再生农业 大量环境科学研究指出,再生农业技术有利于保护自然生态系统。再生农业的宗旨是全面综合地利用土地,比如在本地蔬菜和超级食物植物旁边种植多功能树木,以打造农业生态系统。农业生态系统对社会有诸多好处,比如可以提高当地居民收入和营养摄入,并且将二氧化碳吸收进土壤中。再生农业不仅可以降低碳足迹并实现环境可持续性,还能突破传统的环保方案,直接扭转气候变化的影响。 为了有效应对气候变化,我们必须快速扩张再生农业规模,并在全球范围内推广。这不仅需要政府和大企业的参与,还需要当地企业、社区和个人的参与。除此之外,还要采用合理的机制,高效精准地调动大量资金资源。对小型组织来说,这些挑战难以应对;而大型组织则面临管理成本高企且行动缓慢的问题。因此,我们可以利用混合型智能合约缩小缺口。混合型智能合约拥有区块链自动化和信息透明的优势,可以在各个工作流程之间高效可靠地协调和配置资源,共同达成定义清晰的目标。 混合型智能合约本质上是在区块链网络中运行的软件程序(即:如果发生事件x则触发行动y),可以安全地接入链下数据和系统。混合型智能合约利用去中心化的计算网络以及区块链账本,执行预设定的代码逻辑,并以防篡改的方式记录交易。同时,合约还可以接入链下数据和计算,验证现实世界中的事件并触发支付和罚款。混合型智能合约结合链上和链下两个模块,可以有效提升涉及不同利益相关方的环保举措,比如基于数据激励可持续的能源消耗,以及通过公开验证排放水平建立更有效的问责制。这么做可以让用户获得更清晰的洞察,了解自己所支持的事业是否环保,并为参与者创建更可靠的奖励机制,最终提高所有人的环保意识。 Green World Campaign接入Chainlink,为再生管理奖项注入全球资金 我们非常高兴地宣布向Green World Campaign(绿色世界计划)提供Chainlink社区激励奖金。Green World Campaign项目拥有宏大的愿景,展示了如何利用混合型智能合约扭转气候变化的影响。这笔奖金将提供给Green World Campaign的再生农业项目AIRS,这是一个混合型智能合约应用,接入卫星数据自动分发奖金,以奖励在指定地区开展再生农业的人们,其中包括改善土壤环境、促进碳封存、提高植被覆盖率、改善水文等各种环境修复行为。这些奖励将作为“再生碳”资产以区块链通证形式发放,并且代表Green World信用。通证可以卖给机构以及全球公开众筹的计划,用于恢复自然生态平衡。 Green World Campaign的愿景是在全球范围内开展运动,通过植树造林和发展农业生态,恢复退化的土地,提高农村贫穷人口的生活和健康水平,改善土壤环境并恢复生物多样性,利用生态环境吸收碳排放,并缓解气候变化。他们的目标是在“再生社会”的总体愿景下,将获奖项目规模扩大一百或一千倍,种植几十亿棵树,发展再生农业,为儿童和农民提供环保教育,并为受气候变化影响最大的贫困群体提高收入和营养摄入。 Green World Campaign采用的混合型智能合约应用名为“再生管理自动化激励机制”(Automated Incentives for Regenerative Stewardship,简称AIRS),这个项目由康奈尔大学、加密货币和合约倡议(IC3)、Green World Campaign、Green World Ventures LLC、Green World-Kenya、ETH-Zurich以及ESRI共同发起。 AIRS将远程卫星数据接入混合型智能合约,精准奖励再生农业举措,史无前例地实现流程自动化和透明性,并降低运营成本。奖金支付直接由Chainlink预言机触发,Chainlink预言机负责收集土地实况和卫星数据,在可信执行环境中分析这些数据,得出量化指标,并将结果传输至区块链,触发自动付款。AIRS奖金以加密货币形式发放,这些加密货币可随时兑换成当地货币。另外,奖金也可以数字金融工具的形式发放,以满足当地社区不同的需求。 AIRS采用了卫星数据、Chainlink预言机和混合型智能合约,为再生农业发展提供激励。 AIRS是强大的创新工具,将再生农业发展成果转换成金融工具。目前计划在肯尼亚开展AIRS试点,当地的Green World Campaign团队推出了肯尼亚首个基于社区的补充货币,并且拥有丰富经验和资源,过去十年中一直在当地社区开展再生农业。 Green World Campaign的CEO Marc Barasch表示:“混合型智能合约拥有巨大潜力,可以协调全球资源建立资金激励机制,激励当地社区从事再生农业,并降低碳排放对土地的影响。我们利用区块链技术和Chainlink预言机,可以将奖金更高效地发放给优秀的管理者,所有利益相关方都可以轻松验证结果,而这将反过来鼓励更多人参与,因为他们知道自己投入的精力和资金可以产生可验证的结果。Green World Campaign拥有丰富的人脉和媒体资源,可以为企业、组织和公众伸出援手,共同度过这个机遇与危机并存的关键拐点,让全世界各国人民都可以在“联合国生态系统恢复十年”的发展初期贡献自己的力量,恢复地球环境和生态平衡。” 关于Chainlink社区激励计划 Chainlink社区激励计划为许多开发团队和研究者提供了资金扶持,帮助他们进一步提升Chainlink网络的功能、可用性以及社会影响力。我们欢迎社区中优秀的开发者和开发团队申请激励奖金。如果你是一名研究者,并希望与我们合作,欢迎与我们联系。Chainlink社区激励计划奖金将以现金和/或LINK通证的形式发放。 The post 混合型智能合约助力再生农业发展,逆转全球气候变化 appeared first on Chainlink Blog.
