Mixing / Swapping bitcoin

[X-ray]

your tutorial is too complicated while mixing just using the same scheme as this,they'll receive your bitcoin and then send you an exact amount of bitcoin to your address so why make it more complicated?

there are mixers out there for a reason if it was that easy to just swap then no mixer could profit.

I see some people talk about mixing bitcoins...why dont people just swap bitcoin? EG, Say I have 10BTC and I'll swap one of mine, for one of yours. I give you a wallet address to pay, you pay it, and provide a new address for your coin, which I then pay with one of mine.
Is that not a good way to make your bitcoins a little harder to track?

Actually i think that btc mixing IS swapping of bitcoins.There`s no difference,i guess...

Why are you asking this question OP?

I`m not sure how the mixing process works.

the main purpose of mixing is to cut the "link" between the old coins and the new coins. if you have ever checked one of the bitcoin txs that a mixer like bitmixer sends you can see that it is not possible to find the source.
so a simple swap can never be the same way because it is only one address between the two with one single tx of same size which can be easily tracked.

the question is what you are a looking for to achieve by doing this?

- if it is a simple way to make it harder for other people to find out about your stash and how you use it then there are so may simpler ways. a simple dividing between multiple addresses of your own and using each address once makes it harder for regular users and it is enough privacy for most people. or for more you can send it to and exchange site and then withdraw especially for small amounts like 1BTC your coins will be mixed easily and cheap

- but if you are looking for a better privacy and it is more important for you then you should only use a trusted mixing service and mix your coins. but this is not usually the level of privacy that regular users are looking for.

Do not forget the change address problem. If you want bitcoin that can not be traced to you and do not just want to swap your bitcoin for someone else's trusting a mixer you can use Monero to anonymize your bitcoin. Even Peter Todd recommended this method.

yeah but it all comes down to trust aas well do you trust the person enough and sure eventally it  would be easy tracked if you used the same people.

[SAMKUSH]

Swapping may he difficult because you have to trust the person you swap with, they may run off with the bitcoins you send them, a mixer is this but on a huge scale with tiny amounts, so swapping is the same but it can very easily be tracked. It's best to use a mixer but swapping would work if you had several people.

each person creates a priv/pub keypair and only sends each other the public keys to generate a new multisig public key.
(keep the privkeys a secret, obviously)
they both put funds into the multisig

and then both create the transaction to "spend" the inputs.. and ofcourse both sign it..

obviously if they both dont sign it they both cant spend it.
if you dont see your getting the amount you want. then ofcourse you dont sign it. meaning the other person cant get what they want either.
by both signing it means they both agree to the transaction.

but with that said. its stupid to think swapping/mixing coins needs to be complex or that swapping/mixing coins makes you invisible/anonymous

Isn't the problem here, "they both put funds into the multisig"

Bob puts his 1BTC into the multisig.
Alice claims she is putting it in but doesn't.
Now Alice can hold the Bob's 1BTC ransom, she could demand 50% or she won't sign.

So, how can you guarantee the atomicity of the "they both put funds into the multisig"? or that Bob can remove his coins if Alice doesn't transfer.

same can be said for any escrow service
same can be said for any swap/mixer service
same can be said for any thing really.

this is why LN(a multisig tool) is meant to be the solution to the problems described, although its yet to be seen.
LN's solution is that if funds are not signed for and broadcast to the network within a certain period.. the funds can be send back to sender automatically because a setup transaction is presigned to allow that.

as i said yet to be seen to know if LN is as infallible as advertised. but if so LN will do the things people want in regards to mixing/swapping
