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.

sdk := NewDNASdk()

Next, create an rpc, rest or websocket client.

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

Then, call the rpc server through the sdk instance.

2.2 Wallet API
2.2.1 Create or Open Wallet
wa, err := OpenWallet(path string) (*Wallet, error)

If the path is for an existing wallet file, then open the wallet, otherwise return error.

2.2.2 Save Wallet
wa.Save() error

Note that any modifications of the wallet require calling Save() in order for the changes to persist.

2.2.3 New account
wa.NewAccount(keyType keypair.KeyType, curveCode byte, sigScheme s.SignatureScheme, passwd []byte) (*Account, error)

DNA blockchain supports three type of keys: ecdsa, sm2 and ed25519, and support 224, 256, 384, 521 bits length of key in ecdsa, but only support 256 bits length of key in sm2 and ed25519.

DNA blockchain supports 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.

2.2.4 New default setting account

2.2.9 Get account by index
wa.GetAccountByIndex(index int, passwd []byte) (*Account, error)

Note that indexes start from 1.

2.2.10 Get account count of wallet
wa.GetAccountCount() int
2.2.11 Get default account data
wa.GetDefaultAccountData() (*AccountData, error)
2.2.12 Get account data by address
wa.GetAccountDataByAddress(address string) (*AccountData, error)
2.2.13 Get account data by label

2.2.14 Get account data by index
wa.GetAccountDataByIndex(index int) (*AccountData, error)

Note that indexes start from 1.

2.2.15 Set account label
wa.SetLabel(address, newLabel string) error

Note that label cannot duplicate.

2.2.16 Set signature scheme of account

A multi transfer does more than one transfer of ONT in one transaction.

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.
