I setup a BTC Nitro a while ago but only just got around to letting you all know about it here.
What Does it Do? It helps your transactions get confirmed when sending or receiving btc. To do this, it simply connects to 10 blockchain nodes and rebroadcasts your transaction.
There are some services like this already but I created BTC Nitro because I noticed that:
One of the very popular ones doesn't work properly (Chrome console window shows the errors...one node being used is even on the blockchain test net which is pointless!)
Some of them are a scam and ask for you to send bitcoin, then don't do anything. One of them even asks you to send your wallet recovery seed words (PLEASE NEVER DO THIS!)
Often the public nodes are down or too busy e.g viabtc. BTC Nitro has uses these too but also has access to 10 (geo dispersed) private nodes to rebroadcast through...so your transaction gets rebroadcast more reliably
It was a hobby project for me to work on!
How Do I Use it? All you need to do is paste in your transaction ID (TXID) to the box on the homepage at https://btcnitro.com and hit 'Accelerate'. The rest happens by itself. No need to register or click any ads etc.
What Does it Cost BTC Nitro is free to use. Please enjoy but don't abuse it - no warranties provided. I do have costs in running the service so BTC donations are always welcome but never expected: 3C8UqpkgM7jfBtUuwk4aqXbscap8vZg2JZ
Any Caveats? Yes. If you sent a transaction with zero network fees, then it's unlikely to get picked up by any miner, no matter how much we tell them about it.
What's Next? If people use the service and it becomes popular, I will consider adding features such as the ability to include your TXID in the next block mined by some mining pools where I have connections - increasing your chances of the transaction being confirmed even more. Please don't put your TXIDs here, I will create a separate service thread once I'm ready/willing to do this. For now, please feel free to use BTC Nitro as it is.
If you have any questions, please ask and I'll do my best to answer them. If you disagree with the service I'm providing - that's ok, I'm not forcing anyone to use it, nor am I asking for money!
