Polygon 是以太坊区块链上的 Web3 基础设施，宣布推出 Polygon zkEVM 或零知识以太坊虚拟机，这是一种旨在降低交易成本和提高可扩展性的第 2 层扩展解决方案。
新的零知识（ZK）扩展解决方案 Polygon zkEVM 与现有的以太坊完全兼容（以太币 ) 的智能合约、开发人员工具和钱包使用零知识加密协议，又名 zk 证明。 Polygon 使用 zk 证明将多个交易分组，然后将它们作为单个交易转发到以太坊区块链。
这种将多个交易作为单个交易传输的能力导致更少的汽油费，可以在交易中涉及的各个发件人之间分摊——因此与通过以太坊区块链单独发送它们相比降低了汽油费。
尽管由于链上交易的增加，投资者承受了过高的成本，以太坊的平均汽油费降至 1.57 美元 - 最后一次出现是在 2020 年 12 月。
因此，Polygon zkEVM 处于有利地位，可以进一步降低臭名昭著的天然气价格。 Polygon 承诺通过新推出的解决方案实现更快的结算和更高的资本效率，增加其将 EVM 兼容的去中心化应用程序 (dApp) 轻松迁移到 zkEVM 的能力。
此外，该公司透露，该解决方案还迎合了非同质化代币 (NFT) 和其他基于区块链的应用程序的无缝创建。与第 1 层解决方案相比，Polygon 估计使用 zk-rollup 方法可降低 90% 的成本。
虽然子生态系统继续推出解决方案，希望改进比特币等主要区块链（以太币 ) 和以太坊，内部开发人员通过实施基于共识的升级来支持该驱动器。
在最近的一次电话会议中，以太坊核心开发人员 Tim Beiko 提议将 9 月 19 日作为从工作量证明 (PoW) 挖矿共识到权益证明 (PoS) 关键过渡的暂定目标日期。
这个合并时间表不是最终的，但看到它走到一起是非常令人兴奋的。请以此为规划时间线，以官方公告为准！https://t.co/ttutBceZ21pic.twitter.com/MY8VFOv0SI
