Go SDK For DNA

1. Overview

This is a comprehensive Go library for the DNA blockchain. Currently, it supports local wallet management, digital asset management, deployment/invoking of smart contracts and communication with the DNA Blockchain. In the future it will also support more rich functions and applications.

2. How to use?

First, create an DNASDK instance with the NewDNASdk method.

ontSdk := NewDNASdk()

Next, create an rpc, rest or websocket client.

ontSdk.NewRpcClient().SetAddress("http://localhost:20336")

Then, call the rpc server through the sdk instance.

DNA support multiple signature scheme.

For ECDSA support SHA224withECDSA, SHA256withECDSA, SHA384withECDSA, SHA512withEdDSA, SHA3-224withECDSA, SHA3-256withECDSA, SHA3-384withECDSA, SHA3-512withECDSA, RIPEMD160withECDSA;

For SM2 support SM3withSM2, and for SHA512withEdDSA.

Contributing

Can I contribute patches to the DNA project?

Yes! We appreciate your help!

Please open a pull request with signed-off commits. This means adding a line that says "Signed-off-by: Name " at the end of each commit, indicating that you wrote the code and have the right to pass it on as an open source patch. If you don't sign off your patches, we will not accept them.

You can also send your patches as emails to the developer mailing list. Please join the DNA mailing list or forum and talk to us about it.

Also, please write good git commit messages. A good commit message looks like this:

Header line: explain the commit in one line

The body of the commit message should be a few lines of text, explaining things in more detail, possibly giving some background about the issue being fixed, etc.

The body of the commit message can be several paragraphs long, and should use proper word-wrapping and keep the columns shorter than about 74 characters or so. That way "git log" will show things nicely even when it's indented.

Make sure you explain your solution and why you're doing what you're doing, and not just what you're doing. Reviewers (and your future self) can read the patch, but might not understand why a particular solution was implemented.
