use BitWasp\Bitcoin\Bitcoin;
use BitWasp\Bitcoin\Crypto\Random\RandomGenerator;
use BitWasp\Bitcoin\Key\Factory\ExtendedKeyFactory;
$generator = new RandomGenerator();
$extendedKeyFactory = new ExtendedKeyFactory($generator);
$extendedKey = $extendedKeyFactory->fromEntropy($generator->getBytes(32));
$privateKey = $extendedKey->getPrivateKey();
$publicKey = $privateKey->getPublicKey();
2. 生成地址
完成密钥对生成后,接下来是生成比特币地址:生成地址的过程包含了多次的哈希运算。
use BitWasp\Bitcoin\Address\AddressCreator;
$addressCreator = new AddressCreator();
$address = $addressCreator->fromPublicKey($publicKey);
3. 签署交易
创建交易并使用私钥进行签名,确保交易的有效性。
use BitWasp\Bitcoin\Transaction\TransactionFactory;
$tx = TransactionFactory::build()
->spendOutput($outputIndex, $outputTxId)
->payTo($address, $amount)
->sign($privateKey);
4. 广播交易
最后,广播交易到比特币网络。这可以通过API或运行完整节点进行。
$network = Bitcoin::getNetwork();
$client = new \BitWasp\Bitcoin\JsonRpc\Client($network);
$response = $client->sendRawTransaction($tx->getHex());
