Is Bech32 transaction on size accurate?

I have made a transaction and paid like 120 sat/B, on blockchain it says that I’ve paid 78.995 sat/B and noticed that transaction size is 191 (bytes)

Transaction size supposed to be: 102 (input) + 32 (output) + 10 (headers) = 144 Byte

Is this a problem of and transaction fee is right or the wallet didn’t send the correct fees and Do miners take my transaction as I paid 120 sat/b or 78 sat/b?

I have some misunderstanding regarding how confirmation work on If we go to payment history we can see info about confirmation in two places. First in history of all transactions. Like this

enter image description here

And second place is on the transaction info page enter image description here

Could someone explain me please what’s the difference between this to fields? Why in one place they show Pending status and zero confirmations while in the other one they show 230K confirmations?

Making a service like webservice using Bitcoinj library

In my project I need three type of monitoring on Blockchain network:

  1. Monitor all the transactions
  2. Monitor all new blocks
  3. Calculate confirmations for each hash exactly does the same thing, but it’s not very stable sometimes and I need to apply my own to customization also.

1) Using Bitcoinj, monitoring transactions is easy:

NetworkParameters params = MainNetParams.get(); BlockStore blockStore = new MemoryBlockStore(params); BlockChain chain = new BlockChain(params, blockStore); PeerGroup peerGroup = new PeerGroup(params, chain); peerGroup.start(); peerGroup.addPeerDiscovery(new DnsDiscovery(params)); peerGroup.waitForPeers(5).get(); peerGroup.addOnTransactionBroadcastListener((peer, transaction) -> {     // Get all the transactions here (There is an issue here, this listener calls for each transaction two times) }); 

However this one has an issue, it is called two times for each transaction (I have no idea why).

2) I did not find anything to monitor all the blocks.

3) Also, I don’t hove how to calculate confirmations properly.

I would appreciate if anyone could help me. API response is coming with a big delay

I’m using API on my shop. Everything was fine until about 2 weeks ago. The whole procedure and the issue is: – When a customer place an order, a btc address is created and customer must send a certain amount of funds to this address. – When funds are received on this wallet, is sending a response to my site that funds are paid. – Automatic confirmation emails are sent to the customer when I receive this confirmation from

About 10 days ago, I noticed that the “paid” reply comes with a big delay from Log shows that there is a difference of about 4 hours between creating the invoice and paid responce. At the same time, I see that customer paid his order (3 confirmations) in 25 minutes (for example) after invoice was created.

As to mention, there were no such issue before. Something changed and I cant understand where.
