【Issue 1】 if I want to dependency github.com/PlatONnetwork/PlatON-Go in my go project, it can not be compiled because of bls.git.

I can only compile PlatON-Go locally and then replace it in go.mod.

But for project go-ethereum, works fine to dependency.

【Issue 2】 According to this tutorial https://geth.ethereum.org/docs/dapp/native-bindings, use the tool abigen to generate native binding for .sol file. The output .go file can not be compiled, because abi.ConvertType it is not defined.

【Issue 3】 types.BlockNonce is defined as [81]byte, but in go-ethereum it is defined as [8]byte.

The difference makes some APIs can not be unmarshaled.

你是指通过go get PlatON的方式来作为项目的dependency 无法编译吗？由于PlatON中依赖bls库，需要根据操作系统预先生成bls静态库后方可运行。

PlatON下的abigen还没有同步更新到以太坊的最新版本，后续我们会加入支持。

The difference makes some APIs can not be unmarshaled. PlatON和以太坊的types.BlockNonce的用法不同，以太坊的BlockNonce是一个无意义的随机数，用于工作量证明，与挖矿的难度有关，PlatON的BlockNonce用作存储VRF的证明，因此两边的类型不一致，暂无兼容计划。对于该字段，除了go版本之外的sdk基本都能兼容。
