java - 如何使用 bitcoinj 库离线或在本地主机上发送比特币

Question

我正在开发一个 POC 应用程序，我将拥有多个不同用户的比特币钱包。我正在寻找任何方式将比特币从一个钱包发送到本地主机本身的另一个钱包，而不使用网络来避免网络费用。为了更好地理解；看起来好像我在本地系统上有 2 个或更多比特币钱包文件，其中包含访问它的钱包的所有详细信息。有没有办法将比特币从一个钱包转移到另一个离线（不使用在线网络）。我尝试使用创建 2 个钱包钱包

WalletAppKit kit = new WalletAppKit(params, new File("./wallet"), filePrefix);
kit.startAsync();
kit.awaitRunning();

当我习惯不同时，这个创建的钱包filePrefix或者我可以创建它

Wallet wallet = new Wallet(params);
wallet.autoSaveFile(true);

现在我的机器上有 2 个钱包。我试图创建PeerGroup并尝试connectToLocalhost()但每次它的节目（下面是日志的一部分）

这是我的主类文件代码：

BriefLogFormatter.init();
        NetworkParameters params = TestNet3Params.get();
        try {
            String walletFileName = "wallet/forwarding-service-testnet.wallet";
            final File walletFile = new File(walletFileName);
            Wallet wallet = Wallet.loadFromFile(walletFile, null);

            WalletAppKit kit = new WalletAppKit(params, new File("./wallet"), "filePrefix");
        kit.startAsync();
        kit.awaitRunning();
        LegacyAddress to = LegacyAddress.fromBase58(params, "n2sPiCfFwjDmakuUDEPiTR9WKQkdkFAcaF");
        SendRequest req = SendRequest.to(to, Coin.parseCoin("0.001"));
        req.feePerKb = Coin.valueOf(0);
        req.ensureMinRequiredFee = false;
        try {

            Wallet.SendResult result = kit.wallet().sendCoins(kit.peerGroup(), req);
            System.out.println("Coins sent >> Transaction fee: " + result.tx.getFee());
        } catch (InsufficientMoneyException e) {
            System.out.println("Not enough coins in your wallet. Missing " + e.missing.getValue()
                    + " satoshis are missing (including fees)");
            System.out.println("Send money to: " + kit.wallet().currentReceiveAddress().toString());
        }
            peerGroup.stopAsync();

        } catch (Exception e) {
            e.printStackTrace();
        }

我可以在我的 localhost peergroup 上的 2 个或更多钱包之间转移比特币吗？
