交互全指南：五分钟完成Linea「大航海计划」第六周任务

Linea 是一个新的 zk-rollup 网络，由 ConsenSys 公司研发设计并负责运营，与以太坊虚拟机（EVM）完整兼容。今年 5 月 2 日，Linea 联合 Galxe 正式启动忠诚度计划“Linea Voyage"以鼓励早期用户使用公共测试网，活动为期 9 周，用户可以探索 Linea 生态系统，参与每周挑战并收集积分以领取专属 Linea NFT。

Linea NFT 有什么用？Linea Voyage 最终目的是通过测试网活动为今年晚些时候主网上线做准备，为此官方共准备了四个「版本」的 NFT 作为激励，每个版本对应本次 Voyage 积累的分数阈值。此外，Linea 测试网如果在 Voyage 结束前超过 3000 万笔交易，官方还将额外为所有参与者提供一个纪念版 NFT——纪念版 NFT 并不意味着将来会有 Linea 代币（Odaily星球日报注：换言之，前四个版本的 NFT 大概率有代币空投）。

目前，活动已经进行了五周，第一周是跨链（总分 116 分），第二周是社区活动（15 分），第三周活动主题为 NFT（总分 109 分），第四周完成任务开盲盒（45 分），第五周技术和开发（65 分）。

第六周活动已经正式开启（点击跳转至 galxe 任务页面），从北京时间 6 月 6 日晚上 9 点开始，持续到 6 月 12 日上午 12 点结束；任务完成后，将有额外 24 小时领取积分。本周任务量较少，不涉及链上交互，共有五项。任务全部完成后，即时快照，可以在 galxe 上领取相应的积分；如果想要刷号，转发推文不做也可。

• 观看 Youyutbe 视频，视频全长 1 小时 27 分钟，但无需看完，点击「Watch」跳转至视频页面后等待 20 秒，返回点击「Verify」即可完成任务；（5 分）

• 转发推文，点击「Retweet Now」跳转至任务 Twitter 页面转发即可，而后点击「Verify」即可完成任务；（5 分）

• 回答「简易」模式问题，共有 11 道，答案分别是：AABAD ACBDC D；（10 分）

• 回答「中等」模式问题，共有 14 道，答案分别是：BACAC ACBAA ACDB；（15 分）

• 回答「难度」模式问题，共有 12 道，答案分别是：BBACA CBCBC CB；（20 分）

考虑到有的玩家可能刚刚接触「Linea Voyage」，错过了前期的分数，建议从第四周开始准备多个账户进行交互，通过数量弥补质量。如果已经完成了相关任务，建议早些为下周 Linea 链上做交互。在交互前，请确保你在 MetaMask 钱包中添加了 Lieaa 测试网（点击查询网络信息）以及获得测试币 Goerli ETH： 1 ）直接领取 Linea 链上 0.5 个 GETH（点击跳转），上周水龙头故障，目前已经修复；2 ）从 Goerli 跨链 GETH 进入 Linea，关于如何桥接资产至 Linea，推荐阅读《Linea（ConsenSys zkEVM）测试网交互指南》。

另外，根据社区反馈，官方曾调整过部分问题顺序。Odaily星球日报也将各个问题及答案整理如下，回答时候对照即可。
