如何创建交易

在线上有多个参考资料,它们提供了一些材料来理解其中涉及的步骤.您可以检查此或那.其他问题中也提供了一些元素

基本上步骤是

1. 获取依赖
   • 分支哈希:/chains/main/blocks/head/hash
   • 计数器:/chains/main/blocks/head/context/contracts/<source_pkh>/counter
   • 协议哈希:/protocols
2. forge操作(/chains/main/blocks/head/helpers/forge/operations)请注意,虽然很容易从本地客户端复制此逻辑
3. 符号字节(tezos-client sign bytes)
4. 预先应用操作(/chains/main/blocks/head/helpers/preapply/operations/)
5. 将签名解码为十六进制格式
6. 注入操作(/inject/operation)

There are multiple references online which provide material to understand the steps involved in this. You can check this or that. Some elements are also provided in this other question

Basically the steps are

1. get dependencies
   • branch hash: /chains/main/blocks/head/hash
   • counter: /chains/main/blocks/head/context/contracts/<source_pkh>/counter
   • protocol hash: /protocols
2. forge operation (/chains/main/blocks/head/helpers/forge/operations) Note sure if it's easy to replicate this logic outside from the native client though
3. sign bytes (tezos-client sign bytes)
4. preapply operation (/chains/main/blocks/head/helpers/preapply/operations/)
5. decode signature to hexadecimal format
6. inject operation (/inject/operation)

helpers/scripts/run_operation对于模拟无需签名的操作非常有用(您可以使用零字节进行签名),以便估算天然气和储存要求.您将在此处看到tezos-client -l将gas_limit和storage_limit设置为最大值,然后使用结果将实际的gas_limit和storage_limit设置为(取决于用户的最大可接受的storage_limit,称为"-烧伤帽").

要了解二进制操作如何编码,您可以查看tezos-client describe unsigned operation.

helpers/scripts/run_operation is useful to simulate an operation without signing it (you may use zero bytes for the signature), in order to estimate the gas and storage requirements. You will see tezos-client -l setting gas_limit and storage_limit to the maximum values here, and then using the result to set the actual gas_limit and storage_limit (subject to the user's maximum acceptable storage_limit, called "--burn-cap").

To learn how the operation is encoded in binary, you can see tezos-client describe unsigned operation.

最简单的方法是查看如何eztz实现传输.

然后在这里.

最后如何在此处注入伪造的操作.

从外观上看,eztz的forge似乎是由/helpers/forge/operations远程完成的.

Easiest would be checking out how e.g. eztz implements transfers.

Then see how the transfer operations is forged here.

And finally how the forged operation is injected here.

By the looks of it, seems like eztz's forge is done remotely by /helpers/forge/operations.
