Web3基金会自2018年以来“Grant 计划”的7波共152笔的资助项目，今天将带你一窥波卡的生态建设。
“Grant计划”是Web3基金会在2018年12月发起的，给从事波卡开发或研究的项目资助一笔钱，最高限额10万美元。
Web3基金会每季度公布一批名单，目前已经第7批了，据统计，共资助152笔。
而波卡生态的所有项目加起来，目前也还不到300个。
“Grant计划”是申请制，可能对于项目方而言，钱不钱的倒无所谓，被资助主要意味着被波卡官方所认可。
而这些被认可的项目，从基础设施开发到生态系统组件再到具体的应用，涉及范围相当之广泛(具体名录附文末)。
在所有资助项目中，占据数量最多的是基础模块了——跨链这种极富于想象力的故事当然需要足够多的积木才能玩得转。
所以资助了各种用以跨链的桥(如比特币桥、以太坊桥、Libra桥等)，还有各种钱包和浏览器等。
而有了初始的积木，玩家搭建得顺畅与否也很重要。所以也资助了大量的开发者工具，如测试工具、编译器、代码生成器等。
“Grant计划”资助的第一个项目就是ChainSafe——一个研发各种与区块链无关的工具来协助开发者开发区块链。
在152笔资助中，只有小半的资助匀给了在波卡生态开发的应用项目。但细数的话种类也很可观，从游戏到物联网、社交、存储、DeFi、隐私……
总之，“Grant计划”资助的项目可以说包括了波卡的技术栈的每一层，但我们也能从资助项目中底层技术占最大比例，就能很直观地感受到波卡官方的务实风格。
在“Grant计划”资助的应用类项目中，我们可以划分出很多种类。
比如在物联网领域资助了Nodle，这是一个现成的物联网，号称世界上最大的连接设备生态系统。
之所以资助Nodle，是因为它允许基于Substrate的区块链安全地识别、认证和验证物联网设备。可以说Nodle的出现，为波卡生态增加了一个非常成熟的物联网系统。
比如在游戏领域资助了Xaya和enfipy。Xaya是一个可以创建区块链游戏的平台，并且还是那种应用程序比较复杂的游戏。
比如在存储领域资助了Crust Network和Advanca。Crust是一个类似于Filecoin的分布式存储项目，但也提供云服务。
但“Grant计划”资助最多的是隐私类项目与DeFi项目。
严格来说划分出隐私类项目不够严谨的，因为囊括了很多不同层面的项目，但它们有一个共性，那就是以隐私为中心。
比如Sensio.Group专注于照片版权和隐私的基材模块+ UI，Advanca是一个保留隐私的通用计算和存储项目，ZeroChain则是做零知识交易的，即在一切都保密的前提下又确保了可信……
在最近大火的DeFi领域，“Grant计划”也资助了不少项目。
有去中心化交易所Polkadex、KILT - Polimec、Definex，稳定币Bandot、ACALA PTE，资产合成Laminar One，抵押借贷STAFI等。
尽管波卡主网才刚刚上线，但在生态建设上稳扎稳打，虽然应用类项目还不多，但在基础设施上很完善，目前已渐成羽翼。
相比较其它公链项目的资助计划的项目，波卡实在多了。
