can multiple transactions from the same wallet be tracked to said wallet?

[ThatDevAaron]

if I have a wallet with 100$ and I sent out about 90ish transactions from said wallet, could someone check the ledger and identify said transactions came from the same source?

Without proper care, of course. Have you used coin control? Have you re-used previous addresses or has one of your addresses been linked to a KYC exchange? There are lots of factors your identity depends on, but chances are your transactions are traceable unless you took maximum care of this issue. Consider using ChipMixer or CoinJoin in the future to camouflage your coins' traces, although you should know that usually CoinJoined coins aren't accepted on large exchanges and potentially third party services such as BitPay.

Okay, so if I sent transactions from an Electrum wallet (NO-KYC ON SENDER WALLET), to different addresses every transaction, as you should for anonymity, would the transactions be able to be linked together so they could be identified as all coming from the same electrum wallet to the receiving wallet?

so like, you have A addess (your electrum wallet), and then you send to B, C, D, etc? then it would be obvious that B to D got some tx from wallet A. as mentioned above, you need mixer or coinjoin to obfuscate your txs.

The traceability of the blockchain can publicly record every transaction.
Blockchain.com and BitcoinWhosWho.com are mainly used by two tool websites. The former can be used to browse blockchain records, and the latter can provide detailed information about Bitcoin wallet addresses, and can also be used as a public database to help visitors inquire about addresses related to fraud.

Yes you could track that it came from one wallet because most popular cryptocurrency use public ledger of some sort to list all the transactions happening at any given point in time, this is to help users to confirm that they're transaction went through. I don't really want to help you OP in regards to hiding that address though because I got this vibe in me that I feel like you are going to be using it for something really bad.

[Maus0728]

It can be tracked by looking at the transaction's input and output.

In essence, "inputs" tells you how much bitcoin is being sent to another address, while "outputs" tells you how much bitcoin is being received from that address. That alone should be enough for anyone to figure out where these bitcoins are coming from and where they are going especially if you are repeatedly using that one address.

This is the reason why Electrum has a default gap limit of  20 receiving address to somehow obfuscate their transactions.

[AverageGlabella]

There is something called a change address which when using the same wallet all of your addresses might take Bitcoin from that change address which can then link all of those addresses together. You can read about change addresses on the Bitcoin wiki https://en.bitcoin.it/wiki/Change

This will be the most popular way of tracing coins because people forget that change addresses exist. The best way to avoid getting traced is using a new wallet for every transaction or using a mixer if they are legal in your country of residence.

Maybe. Maybe not.

There is nothing at a blockchain level which can identify different addresses as belonging to the same wallet. If I create a new Electrum wallet today with 100 addresses in it, the only person who knows those 100 addresses are linked in the same wallet is me.

For these addresses to be linked in the publicly viewable blockchain, then you need to make transactions which link them together. For example, if you use Address A and Address B together in the same transaction, then those addresses can be linked. If you send coins from Address A to someone else and receive some change to Address B, then it might be possible to link those addresses as belonging to the same wallet.

There are other ways that transactions can link addresses together, and you can also leak information about your addresses in other ways, such as by querying them all through an Electrum server.

You mixed addresses and wallets in your reply. If you have coins in address A, as soon as you send from address A to Receiver B, the remaining balance from address A (if there is any) will go to change address X. They won's stay on your address A. Your address X doesn't necessarily have to be linked with address A and be identifiable to belong to the same wallet. It could be seen as a change address or a second receiver.

Wallet balance is a collection of all balances with all addresses (UTXO) that were listed in previous blocks, so if you do not control how to send your money and how to control your privacy, your transactions will be tracked.
One way to increase security is to use a well-programmed wallet that supports coin control.

If you sent coins partially and used the same change address than it's trivial to connect all those addresses and identify they are coming from same source.
Sending all coins from multiple addresses is doing the same thing and reducing your privacy.

Bitcoin is a public ledger so regular transaction can easily be linked together, but you can always use mixers like Chipmixer or coinjoin to break the connection for your coins.
You can generate and use many addresses in Electrum and you can keep them separately, and it's good to receive Bitcoin in new address each time.

Depends. For example, if you're using Electrum on public nodes rather than running your own, the node owners might know very easily that one particular IP (whether run through Tor or not, it doesn't matter) owns all these addresses since when you're running a lightweight wallet, the public servers have to look after your addresses balance upon request.

The first request is straight when you open up the wallet for the first time, so unless you've run it through your own node/server, the public node will know that you own the set of addresses it had to look up through the blockchain.

Also, make sure you do not link your addresses together in transactions.

[Kittygalore]

IIRC there's some sort of public ledger for many cryptocurrencies that acts as a way to make sure that everything is transparent and that we should be able to see and confirm our transactions, but if you're looking for something else then probably you should check on privacy coins, they're the extreme version of cryptocurrency, they actively try and prevent people from know who is behind the transaction and what's the movement of their money using the privacy coins.

To different addresses or from different addresses? For anonymity’s sake generate new sendable addresses for each transaction, and the receiver (ideally, all of them) should do the same. In that case, I believe, you can’t be tracked, and any of your previous and future transactions can’t be confirmed to be linked with each other or with the receiver.

[o_e_l_e_o]

You sound confused.

You cannot generate "new sendable addresses" for coins that are being sent in a transaction. Inputs to transactions in the form of UTXOs can only come from the address they were previously sent to. You should generate and use a new address for each time you receive bitcoin from someone else and each time you return bitcoin to yourself as change. But once you have received bitcoin, you can only spend it from the same address which received it. This is the reason you need to be careful about combining different inputs in to the same transaction, because it links those addresses together with common ownership.

Yes if you are not careful, I think it is much better to practice using different address for receiving coins and never use again previous addresses. I'm not really sure if they can be track even if you use different address, but I'm sure that's a good practice.

LOL if I was going to use it for something very bad I'd setup software to gen random wallets, move funds to said wallets then transmit the wallets so that it looks sp00ky, but im not using for anything bad lol <3
