7月24日，Solana 发布最新路线图，明确实现 The Internet Capital Markets 互联网资本市场目标，即成为链上与现实资产的流动性中心。
为了实现该目标，Solana 核心开发者实际进行明确分工，形成合力。其中，Jito、Anza 负责区块组装市场 BAM，本文主角 DoubleZero 和 Anza 负责 IBRL（Increase Bandwidth Reduce Latency，增加带宽减少延迟），还有新共识机制 Alpenglow。
如上文，DoubleZero 核心目标是增加 Solana 网络宽带，减少延迟，主要两种方式——部署专有宽带硬件或整合闲置宽带；优化公链交易数据流。
首先，Doublezero 可以整合企业、机构闲置宽带资源，供给 Solana，提高网络速度。
其次，负责实现流量过滤、签名验证和垃圾信息防护。将过滤和验证工作，从公链节点里分离出来，让节点专注交易打包、区块生产和执行，实现扩容。
为什么要这样做？这要从 Solana 节点验证者的工作说起。验证者的工作包含两个基本步骤：生产区块和就区块达成共识。
区块生产从海量未过滤的数据涌入验证者时开始。验证者需要先执行去重、过滤和签名验证等操作，缩减候选交易池，然后从中选择有效交易打包成区块，并广播给其他验证者达成共识。
其他验证者要么批准该区块并将其添加到链上，要么拒绝并等待下一个区块。
问题就出在这里。系统的性能瓶颈，越来越多地出现在验证者之间的通信上——主要是带宽限制和延迟波动，而不是验证者自身的计算能力。因此**，**要突破性能极限，关键在于优化数据流。
这正是 DoubleZero 要解决的核心问题，将各方贡献的光纤线路整合成一个同步网络，能够过滤垃圾信息、提升带宽、降低延迟，并消除通信中的抖动(jitter)。
从架构上看，DoubleZero 由两个关键组件构成：网络设备硬件，以及跨网络部署的带宽资源。它们共同构成了一个网状网络，即 DoubleZero 网络。
DoubleZero 网络上的设备承担两项核心功能：
1）将个人和组织贡献的数据链路整合；
2）负责流量过滤、签名验证和垃圾信息防护。
通过这种设计，过滤验证与交易打包、区块生产和执行实现了分离，创建出一个并行且受保护的交易流,让节点运营者能够优化网络运行效率。
如果用更直观的方式理解，DoubleZero 网络架构可以看作两个同心环：外层的入口/出口环和内层的数据流环。
外环与公共互联网相连，DoubleZero 在这里部署使用高性能硬件，用于抵御 DDoS 攻击、验证签名和过滤重复交易。
内环上的服务器则利用这些已过滤的流量，通过最优路由的专用带宽线路来达成共识。最终实现 Solana 网络速度扩容。
主网上线后，已有 30.69%的质押 $SOL 接入 DoubleZero。这个表现相当不错。
代币经济模型如下图，实际上 Foundation 基金会、Jump Crypto、Malbec Labs、Team、Contributor 贡献者、Builders 建设者部分都是团队自己，占代币总量 87%。只有机构 12%和 Validators 验证者是给到外部的筹码。
唯一问题是作为基础设施项目，FDV 必然不会很低。以 0.2315 价格计算，FDV 达到 23.15亿美元，市值 8.03亿美元。
