To get this integrated more officially into go-ipfs, we will need to first clean the code here up a little (make sure it complies with golint and vetting tools) and then make it confirm to the newer go-ipld-format plugin semantics (it needs a DecodeBlock method matching this: https://github.com/ipfs/go-ipld-format/blob/master/coding.go#L13) Then in an init function, it needs to register itself in the decoders map.

Then, any build of go-ipfs that imports this package will automatically be able to handle ethereum types.

There are also a few changes from https://github.com/ipfs/go-ipfs/compare/feat/zcash that we will need to get merged (primarily the changes to the ipfs dag put command that allows hex input).

And finally, this package doesnt implement handling for all the different ethereum object types. I only did block, transaction, and transaction trie parsing. Working on support for state trie processing will be nice.

It's probably a good idea to cache the CID (and, if possible the output of RawData) as these methods are often called repeatedly in fast-path code.

Hi,
I have met some problem when building go-ipld-eth as a plugin. Here are the errors:

cannot use d (type "gx/ipfs/QmVSase1JP7cq9QkPT46oNwdp9pT6kBkG3oqS14y3QcZjG/go-
datastore".Batching) as type "github.com/ipfs/go-datastore".Datastore in argument to namespace.Wrap

I thought it's something about gx tools. But, i do not know how to solve it.
So, anyone can help
ThankU

Hey, there

Thanks in advance and wish you a nice day ^^

We have a way to build plugins directly into the go-ipfs binary, this would allow users of windows and macOS to use this code natively, but would require they recompile. It also requires a little bit of changes in this package. Notably, we need to separate the 'package main' plugin code from the rest of the plugin scaffolding. And would end up with the main plugin file looking like:

package main

import (
     "ipldethpluginimportpath"
)

var Plugins = ipldeth.Plugins

See https://github.com/ipfs/go-ipfs/blob/master/plugin/loader/preload_list and other code in that directory.
