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 來構造 Template 對象參數, 單簽
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 來構造 Template 對象參數, 多簽
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 來構造 Template 對象參數, 多簽, 多輸入
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()

        .setAssetId(asset_id)
        .setAmount(300000000)
    )    // 2 input

使用Java SDK實現離線簽名

摘要：當使用構建完成一筆交易并簽名后，若沒有全節點的幫助，也需要自己實現網絡協議將交易廣播到其他節點。其中，第一個依賴是的封裝，可用于查詢可用的以及提交交易第二個依賴用于構建交易以及對交易進行離線簽名。嚴格來說，tx-signer并不屬于SDK，它是bytomd中構建交易、對交易簽名兩大模塊的java實現版。因此，若想用tx-signer對交易進行離線簽名，需要由你在本地保管好自己的私鑰。...
