Can i check bitcoin balance by address with QBitNinja client without my own node?
public static void Main(string[] args)
{
var client = new QBitNinjaClient(Network.TestNet);
var address = new BitcoinPubKeyAddress("1May3uZes7Qh629mPG8WXZbMjhZQJ6QeRK");
var balance = client.GetBalance(address).Result;
}
No. The readme specifies BitCoin Core, synchronized (so a full node), as a pre-requisite. The Setup the indexer section also states that it listens to a full node.
