比原项目仓库：

Github地址：https://github.com/Bytom/bytom

Gitee地址：https://gitee.com/BytomBlockc...

tx_signer

Java implementation of signing transaction offline to bytomd.

Pre Get the source code

$ git clone https://github.com/Bytom/bytom.git $GOPATH/src/github.com/bytom

git checkout

$ git checkout dev

Why need dev branch? Because you could call decode transaction api from dev branch and obtain tx_id and some inputs ids.

Build

$ cd $GOPATH/src/github.com/bytom
$ make bytomd    # build bytomd
$ make bytomcli  # build bytomcli

When successfully building the project, the bytom and bytomcli binary should be present in cmd/bytomd and cmd/bytomcli directory, respectively.

Initialize

First of all, initialize the node:

$ cd ./cmd/bytomd
$ ./bytomd init --chain_id solonet

launch

$ ./bytomd node --mining

Usage Build jar

first get source code

git clone https://github.com/successli/tx_signer.git

get jar package

$ mvn assembly:assembly -Dmaven.test.skip=true

You can get a jar with dependencies, and you can use it in your project.

Test cases

Need 3 Parameters:

Private Keys Array

Template Object

After call build transaction api return a Template json object. build transaction api

use bytom java sdk return a Template object.

Raw Transaction

call decode raw-transaction api from dev branch. decode raw-transaction api

Call method:

// return a Template object signed offline basically.
Template result = signatures.generateSignatures(privates, template, rawTransaction);
// use result"s raw_transaction call sign transaction api to build another data but not need password or private key.

Single-key Example:

@Test
// 使用 SDK 来构造 Template 对象参数, 单签
public void testSignSingleKey() throws BytomException {
    Client client = Client.generateClient();

    String asset_id = "ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff";
    String address = "sm1qvyus3s5d7jv782syuqe3qrh65fx23lgpzf33em";
    // build transaction obtain a Template object
    Template template = new Transaction.Builder()
        .addAction(
        new Transaction.Action.SpendFromAccount()
        .setAccountId("0G0NLBNU00A02")
        .setAssetId(asset_id)
        .setAmount(40000000)
    )
        .addAction(
        new Transaction.Action.SpendFromAccount()
        .setAccountId("0G0NLBNU00A02")
        .setAssetId(asset_id)
        .setAmount(300000000)
    )
        .addAction(
        new Transaction.Action.ControlWithAddress()
        .setAddress(address)
        .setAssetId(asset_id)
        .setAmount(30000000)
    ).build(client);
    logger.info("template: " + template.toJson());
    // use Template object"s raw_transaction id to decode raw_transaction obtain a RawTransaction object
    RawTransaction decodedTx = RawTransaction.decode(client, template.rawTransaction);
    logger.info("decodeTx: " + decodedTx.toJson());
    // need a private key array
    String[] privateKeys = new String[]{"10fdbc41a4d3b8e5a0f50dd3905c1660e7476d4db3dbd9454fa4347500a633531c487e8174ffc0cfa76c3be6833111a9b8cd94446e37a76ee18bb21a7d6ea66b"};
    logger.info("private key:" + privateKeys[0]);
    // call offline sign method to obtain a basic offline signed template
    Signatures signatures = new SignaturesImpl();
    Template basicSigned = signatures.generateSignatures(privateKeys, template, decodedTx);
    logger.info("basic signed raw: " + basicSigned.toJson());
    // call sign transaction api to calculate whole raw_transaction id
    // sign password is None or another random String
    Template result = new Transaction.SignerBuilder().sign(client,
                                                           basicSigned, "");
    logger.info("result raw_transaction: " + result.toJson());
    // success to submit transaction
}

Multi-keys Example:

Need an account has two or more keys.

@Test
// 使用 SDK 来构造 Template 对象参数, 多签
public void testSignMultiKeys() throws BytomException {
    Client client = Client.generateClient();

    String asset_id = "ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff";
    String address = "sm1qvyus3s5d7jv782syuqe3qrh65fx23lgpzf33em";
    // build transaction obtain a Template object
    // account 0G1RPP6OG0A06 has two keys
    Template template = new Transaction.Builder()
        .setTtl(10)
        .addAction(
        new Transaction.Action.SpendFromAccount()
        .setAccountId("0G1RPP6OG0A06")
        .setAssetId(asset_id)
        .setAmount(40000000)
    )
        .addAction(
        new Transaction.Action.SpendFromAccount()
        .setAccountId("0G1RPP6OG0A06")
        .setAssetId(asset_id)
        .setAmount(300000000)
    )
        .addAction(
        new Transaction.Action.ControlWithAddress()
        .setAddress(address)
        .setAssetId(asset_id)
        .setAmount(30000000)
    ).build(client);
    logger.info("template: " + template.toJson());
    // use Template object"s raw_transaction id to decode raw_transaction obtain a RawTransaction object
    RawTransaction decodedTx = RawTransaction.decode(client, template.rawTransaction);
    logger.info("decodeTx: " + decodedTx.toJson());
    // need a private key array
    String[] privateKeys = new String[]{"08bdbd6c22856c5747c930f64d0e5d58ded17c4473910c6c0c3f94e485833a436247976253c8e29e961041ad8dfad9309744255364323163837cbef2483b4f67",
                                        "40c821f736f60805ad59b1fea158762fa6355e258601dfb49dda6f672092ae5adf072d5cab2ceaaa0d68dd3fe7fa04869d95afed8c20069f446a338576901e1b"};
    logger.info("private key 1:" + privateKeys[0]);
    logger.info("private key 2:" + privateKeys[1]);
    // call offline sign method to obtain a basic offline signed template
    Signatures signatures = new SignaturesImpl();
    Template basicSigned = signatures.generateSignatures(privateKeys, template, decodedTx);
    logger.info("basic signed raw: " + basicSigned.toJson());
    // call sign transaction api to calculate whole raw_transaction id
    // sign password is None or another random String
    Template result = new Transaction.SignerBuilder().sign(client,
                                                           basicSigned, "");
    logger.info("result raw_transaction: " + result.toJson());
    // success to submit transaction
}

Multi-keys and Multi-inputs Example:

@Test
// 使用 SDK 来构造 Template 对象参数, 多签, 多输入
public void testSignMultiKeysMultiInputs() throws BytomException {
    Client client = Client.generateClient();

    String asset_id = "ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff";
    String address = "sm1qvyus3s5d7jv782syuqe3qrh65fx23lgpzf33em";
    // build transaction obtain a Template object
    Template template = new Transaction.Builder()
        .setTtl(10)
        // 1 input
        .addAction(
        new Transaction.Action.SpendFromAccount()
        .setAccountId("0G1RPP6OG0A06") // Multi-keys account
        .setAssetId(asset_id)
        .setAmount(40000000)
    )
        .addAction(
        new Transaction.Action.SpendFromAccount()

使用Java SDK实现离线签名

摘要：当使用构建完成一笔交易并签名后，若没有全节点的帮助，也需要自己实现网络协议将交易广播到其他节点。其中，第一个依赖是的封装，可用于查询可用的以及提交交易第二个依赖用于构建交易以及对交易进行离线签名。严格来说，tx-signer并不属于SDK，它是bytomd中构建交易、对交易签名两大模块的java实现版。因此，若想用tx-signer对交易进行离线签名，需要由你在本地保管好自己的私钥。...
