Quote from: Hitch on August 14, 2013, 08:06 am There's a lot of differing opinions, it seems. From what I've read I've been thinking bitcoins aren't individually identifiable, it's just the transactions in the blockchain that are permanent and easily tracked/monitored. Tumblers, therefore, aren't there to give you random coins, but to obfuscate the progress of your coins from destination A to destination B. Can anyone clarify, please?You've got the idea: all transactions are public knowledge, but we don't have any really identifiable information associated with them except our BTC addresses. It's kind of like a credit card I guess, except nobody knows who owns which number (without some further information, such as what Coinbase or other companies can provide about their users). Bear in mind that the blockchain isn't so much a record of transactions, it's literally the transaction ledger that the world goes by.In fact, there aren't actually any bitcoins in your wallet -- or anybody's for that matter. They don't even exist in the way we all think about them. It's basically nothing more than a record of coins having been sent to that address, and not having been sent anywhere else yet, so when you broadcast a transaction the network accepts it. :) It may seem like a pointless bit of trivia, but what I'm getting at is that the blockchain pretty much *is* the transaction, not just a record of it.
