February 27, Bitcoins can buy you a TAG Heuer watch, a cross-country flight or a meatball marinara sub. But really, how does it work? Purchases with bitcoin and other digital currencies remain rare relative to cash and credit cards. Many bitcoin holders value it more as an investment than a day-to-day currency. And the complex workings behind the notoriously volatile currency can be off-putting to neophytes.

Instead, we want mix transactions to be uniform in value so that linkability is minimized. All mixes should agree on a standard chunk size I’ve also seen mixing in Bitcoin described differently, for transactiob in the Bitcoin and Beyond paper:. The mixing service aggregates bitcoins received from all its users to re-distribute them.
Some services use randomness, i. The user can schedule the transactions and provide time constraints. Now I’m looking for examples of these types of mixing transactions in the blockchain, especially one where I can see a fixed chunk size being used. Is one of these schemes used more frequently nowadays? Is the second scheme really secure? If THIS is actually mixing like I assume, then isn’t it possible to match sets of inputs to sets of outputs that have the amount or slightly less BTC value and therefore bitciin to be connected?
I can imagine that this does also work over the course of multiple transaction in case the payout of a mixer is split into intervals. As I see it, the techniques you are referring to are two possible but different ways of doing mixing.
The first one, explained in Bitcoin and Cryptocurrency Technologies book is referring to a kind of mixing technique like CoinJoin. CoinJoin is a mixing technique in which several users create a transaction by joining their inputs. In order ued maintain their privacy, all inputs should share the same value, since in that way once the transaction is created there is no way of telling which anatomy of a bitcoin transaction buying a used subaru correspond to each output, whereas if the inputs hold different value it will be way more straight-forward.
There are to ways of implementing a CoinJoin scheme, the first and more simple one relays in a third party receiving all inputs, outputs and signatures, and building the transaction from the participants. The other one, more elaborated, does not need any third party, since every user acts as a blind-signing server.
On the other hand, the technique referred in the Bitcoin and Beyond paper uses a mixing server, which acts as a trusted third party, where users will send funds and eventually receive them back in a different address after applying a certain mixing fee. In order to avoid linkability between received and sent transactions, this kind of mixing technique uses randomized delays to redistribute transactions.
