Monitoring sequence of btc transactions

[pooya87]

If I understood your question correctly, you don't need to use an escrow at all.
You both want to send some coins to a destination, right? Lets say you want to send 1BTC and your partner wants to send 2BTC. So you can easily create a transaction that has an output with the total 3BTC, then include your own input(s) in it with the total being 1BTC and sign each input using the ANYONECANPAY sighash. Then the other party can also sign it using the same sighash while adding their own input(s) with the total being 2BTC.

Keep in mind that the transaction itself remains invalid until the sum of all inputs surpasses the total of 3BTC.

Other details may be needed like what the destination is (one or more addresses) or its type (like using 2-of-2 multisig) and stuff like that which depends on what it is you are trying to do.

This is funny. Since you trust your friend, why not send directly to his wallet and he also send directly to your wallet and after that you guys can send it back to one another.

Of course, I just don't understand what he wants. If he and his friend trust each other, they can make transactions between them, but the transactions he proposes to make are a bit strange. Using an intermediary, which would have to be a trusted escrow, otherwise there is a risk of losing the money, is usually when there is not enough trust between the two parties.

This has a history, but there's no trust. But we need these transactions to be made. The problem is my partner won't trust a person he doesn't know with $1800. Are the escrow wallets setup as multisig?

Sounds interesting, but I don't quite understand. We don't want to send our coin to the same address, but to each other's address

just use a multisig

both sides send a public address to each other
use those addresses to create a 2 of 2 multisig
(if you want 2 multisig addresses(escrows) both sides create 2 public addresses each and share them to create 2 multisigs)


fund the multisig and then when its funded you both have to decide on the destination(s) and amount of the fund(s) which you then both sign for

no middle man needed. just each other being co-signers to make sure it only leaves the multisig when both sides are happy with destination and amount and time to let it be spent

in short you both become your own escrow

That sounds interesting.
But unsure if I understand.
So you use multisig to release the escrow?
Can you use multisig to create two transactions at once?
, but I don't understand how you solve the problem that one deposit is released by one party, and the other is not

Welcome to bitcointalk platform. I will commend you for taking this bold steps coming here and also presenting or having such offer here. Be rest assured that you are on the right track. I believe you must have heard about this platform elsewhere to have come here with such a deal.

As you can see for yourself, members already proffered solutions and ideas to you and you can choose from them any that suits your requirement and I would also advise you clearly state your requirements or you check out for the requirements of the escrows if you can be able to meet up with their conditions.

Here's a link to some notable and reputable escrow services with track records as initially provided by members.

And adding a escrow also costs money, as he will charge for the service.

Maybe they aren't friends?

Maybe there is also more to the service that the OP has yet to explain. As it's stated on the last part, "an account they can send $900" into which they will get back after the completion of the transaction, could they be dealing in some kind of business that they don't want to share details about?
 
I don't get why someone can just decide to send transactions to one another for no reason, wasting the fees that it will cost them for each transaction.

yes we're not friends, and we have a history. and there will be processing between the two transactions. i just didn't mention it because I thought it was not relevant to the question.

This is something I'm always cautious about – in general, you don't want to send money to someone you don't fully trust. The same goes for Bitcoin transactions.

If using a trusted escrow service isn't an option for both of you, then maybe you can try a smaller, incremental approach.  For instance, you could send $50 worth of Bitcoin first, and then they could send $100 back.  It might mean a few more transaction fees, but at least in the worst-case scenario, neither of you would be risking a big amount.

Sometimes the issue is not about knowing bitcoin, but about having basic financial experience, but we want to do things when we don't even know the traditional.

In traditional banking there is what is known as joint signatures, let's say that three people open an account and of those three, two people authorize the payment with their signature, that is, 3 out of 2, then,  what you are mentioning is resolved.

Since 2 out of 2, there is that possibility, one does not agree and the transfer or check is not approved, the same happens with bitcoin, the big difference is that to solve that in bitcoin there is only trust.

They have given you several solutions, I just used common sense, or some life experience, street, this is not rocket science, don't get complicated with something so simple.

Trust is a priority in bitcoin for P2P, if it does not exist, channel common sense and use the tools mentioned.

   An input sequence or nSequence in Bitcoin has to do with a field of a Bitcoin transaction input , which was initially wanting to make payment channels almost the same as the Lightening network .

   As soon as a miner solves a cryptographic(mathematics) puzzle,a transaction is said to be verified , which the Bitcoin make use of a protocol known as the proof -of-work, which has a wide aim to prevent  Cyber attack from any one entity or group . Bitcoin uses the Secures Hash Algorithm 256 bit (SHA- 256).

The intermediary you have to look for also needs to be trustworthy. It should be someone that has a legal background preferably instead of just someone that both you and your partner knows like a friend because it would be very easy for one to bribe the other.

There are lots of escrows in the internet. It is preferably that it is a complete stranger to the both of you with credibility and expertise because of the reason I previously stated.

Me and my partner want to engage in a sequence of Bitcoin transactions. The first transaction involves me sending $400 in BTC, and the second transaction involves my partner sending me $900 in BTC. To establish trust, both of us are willing to deposit $900 in BTC into an account, which will be returned to us after the completion of the transactions.
How should we proceed? How do we find a trusted intermediary?

Edit: To clarify: "the partner" is just a person I met on the internet, there is no trust relationship between the two uf us. It is in both our interests that this sequence of transaction will take place as described.

Thanks a lot for your inputs!

If you want to do escrow then of course there are many trusted people in this forum through whom you can complete the transaction.  @yahoo62278, @icopress, @hugeblack etc person stream you can complete the transaction.  They always work faithfully and selflessly in the forum

There has to be a reason for these transactions IMO before any reputable person here is going to help. Going just by the scenario you described it would look just like trust farming, which will end up not looking so good for you or your "partner".

The intermediary you have to look for also needs to be trustworthy. It should be someone that has a legal background preferably instead of just someone that both you and your partner knows like a friend because it would be very easy for one to bribe the other.

You should probably not comment unless you have a clue of how a situation works. Plenty of people on this forum have held a lot more then $900. Whether they held it for an escrow deal, a signature campaign, or just because someone asked them to, they did it without any issues. If you want to spam, go spam gambling discussion.

You are right if two people have a good relationship and there is trust, their relationship will not be destroyed if they transact. Therefore, in terms of relationship, transactions must be done very carefully so that their relationship is not damaged due to this transaction. From that point of view, he can trade, but before trading, he needs to have enough knowledge about Bitcoin so that he does not trade in the wrong place, since the transaction will be done on borrowed money, so he has to make the right decision. If he invests in a wrong place, he may face losses, so he should invest carefully.
