专家问答为SuiMay 29, 2025当 Move 结构有命名字段时，为什么 BCS 需要精确的字段顺序才能进行反序列化？
当 Move 结构有命名字段时，为什么 BCS 需要精确的字段顺序才能进行反序列化？ 我一直在深入研究 Move 中的 BCS 编码/解码，特别是跨链通信和链下数据处理. 在浏览 Sui Move 文档中的示例时，我遇到了一些似乎违反直觉的行为，我正在尝试理解底层的设计决策. 根据BCS规范，“BCS中没有结构（因为没有类型）；该结构只是定义了字段序列化的顺序. ”这意味着在反序列化时，我们必须按照与peel_*结构字段定义完全相同的顺序使用函数. 我的具体问题： 设计理由：当 Move 结构具有命名字段时，为什么 BCS 需要精确的字段顺序匹配？像 JSON 或其他自描述格式一样，将字段名称与值一起序列化不是更强大吗？ 泛型类型交互：文档提到 “包含泛型类型字段的类型最多可以解析到第一个泛型类型字段. ”考虑一下这个结构： struct ComplexObject has drop, copy { id: ID, owner: address, metadata: Metadata, generic_data: T, more_metadata: String, another_generic: U } 部分反序列化在这里到底是如何工作的？我可以反序列化到more_metadata并忽略两个泛型字段，还是第一个泛型字段（generic_data）完全阻止了进一步的反序列化？ 跨语言一致性：使用 @mysten /bcs JavaScript 库序列化将由 Move 合约使用的数据时，在以下情况下会发生什么： -我不小心重新排序了 JavaScript 对象中的字段？ -Move 结构定义会在合约升级中更改字段顺序？ -我有带有自己的泛型参数的嵌套结构吗？ 实际启示：在生产系统中，团队如何处理 BCS 架构演变？您是否对BCS架构进行了版本控制，还是期望结构字段顺序在部署后不可变？

专家问答为MoveMar 11, 2025Sui Move vs Aptos Move - What is the difference?
Sui Move and Aptos Move - two prominent implementations of the Move programming language. While both are rooted in the same foundational principles, they have diverged significantly in design, execution, and ecosystem development. To better understand their differences, we need to uncover some of their key aspects: How do their runtimes differ? Both Sui and Aptos implement their own custom Move virtual machines (VMs). How does this impact performance, scalability, and developer experience? For instance: Does Sui's runtime optimize for parallel execution differently than Aptos'? Are there notable differences in transaction lifecycle management or gas models? What are the differences between their standard libraries? The Move standard library is a critical component for building smart contracts. However, Sui and Aptos have forked their implementations, leading to divergence: Are there modules or functions unique to one implementation but absent in the other? How do these differences affect common use cases like token creation, NFTs, or decentralized finance (DeFi)? How does data storage differ between them? One of the most significant distinctions lies in how Sui and Aptos handle data storage: Sui uses an object-centric model, where each object has its own ownership and permissions. Aptos, on the other hand, retains a more traditional account-based model similar to Ethereum. How does this impact state management, composability, and gas efficiency? Is it fair to say that Aptos is closer to EVM while Sui is closer to SVM? Some developers argue that Aptos' account-based architecture resembles Ethereum's EVM, while Sui's object-centric approach aligns more closely with Solana's SVM. Do you agree with this analogy? Why or why not? How does this architectural choice influence developer ergonomics and application design? Are there universal packages working for both Sui Move and Aptos Move? Given their shared origins, it would be ideal if some libraries or tools were interoperable across both ecosystems. Are there any existing universal packages or frameworks that work seamlessly on both platforms? If not, what are the main barriers to achieving compatibility? Can one of them be transpiled into another? If a project is built on Sui Move, could it theoretically be transpiled to run on Aptos Move, or vice versa? What are the technical challenges involved in such a process? Are there tools or compilers currently available to facilitate this kind of migration?

专家问答为SuiMar 05, 2025Sui Move 模块出版物中的 “多源验证错误” ——自动错误解决
使用 Sui Move 的开发人员在尝试发布或升级模块时经常遇到与 “发现多源验证错误” 相关的问题. 这些错误是由于本地依赖项与其链上依赖项之间的不匹配而发生的，从而导致发布失败和部署挑战. 以下是开发人员面临的错误的综合示例： Failed to publish the Move module(s), reason: [warning] Multiple source verification errors found: Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::vec_set Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::vec_map Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000001::MoveStdlib::bit_vector Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000001::MoveStdlib::ascii Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::hex Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::zklogin_verified_id Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::prover Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::coin Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::dynamic_field Local dependency did not match its on-chain version at 0000000000000000000000000000000000000000000000000000000000000002::Sui::transfer On-chain version of dependency Sui::zklogin_verified_id was not found.
