Re: Where do bitcoin states get stored?

This is not correct. Your coins aren't stored in your wallet but in the blockchain as unspent tx outputs. A wallet is just a tool to interact with the blockchain using your keypairs (public and private keys).

In fact, you don't even need a wallet to send/receive bitcoin, you can use a tool such as coinb.in to create the raw transaction, sign it then broadcast it to the network.

Thanks! this answer was very helpful : )

This is actually a great idea!
There is a need for this since the current one is not sufficient at all.

من زمانی که تو فورم ثبت نام کردم سعی کردم یه بورد ایجاد کنم و از مادریتورها پرسیدم اما کسی همکاری نکرد.
بعدتر سعی کردم دومین مشابه بگیرم و یه فورم راه‌اندازی کنم اما دیدم کارآمد نیست چون به اندازه‌ی این فورم به راحتی پیدا نخواهد شد.
امیدوارم شما بتونید یک بورد برای فارسی زبانان ایجاد کنید؛ نیازش قطعا وجود داره.

Your question is somehow complicated and understandable cause I have never read where Bitcoin has a state and it will be appreciated if you can be more specific with your question for better understanding. But if you're referring to where Bitcoin is stored, it is store on Keys and the keys come in 2 pairs.

I was reading ETH whitepaper & this caught my attention:
 
"The "state" in Bitcoin is the collection of all coins (technically, "unspent transaction outputs" or UTXO) that have been mined and not yet spent, with each UTXO having a denomination and an owner (defined by a 20-byte address which is essentially a cryptographic public keyfn. 1)."

Then, further in the whitepaper [about the ethereum] he talks about Patricia tree & adds:

"Additionally, because all of the state information is part of the last block, there is no need to store the entire blockchain history - a strategy which, if it could be applied to Bitcoin, can be calculated to provide 5-20x savings in space.

then i thought what is the mechanism of checking the states if they're not in the block? I've never thought of it before & I believe i need to read a bit more about chainstates.

Hello friends,

Where do bitcoin states get stored?

& what happens to the slate blocks [which calculated the hash after the found block by some other miner] in detailed look?

hello friends,


i have a 2 part question;
it's being said that the states are stored into the blocks in ethereum. Shouldn't they be stored anyway? where are bitcoin states get stored if not in the block?


& What does this sentence even mean? >
"A special kind of tree known as a "Patricia tree" is used to accomplish this, including a modification to the Merkle tree concept that allows for nodes to be inserted and deleted, and not just changed, efficiently. " insert and deletion of nodes? what does he mean by that?

"Additionally, because all of the state information is part of the last block, there is no need to store the entire blockchain history"
is the state the only thing needed for trxs to be verified? he means knowing state is enough for what?

Why are light nodes mean a partial trust?

light nodes are able to check the block header which contains the merkel root and if anything was manipulated, the root would have been changed.
with all that in mind, why do we still consider them not fully trusted?

Re: overflow incident

I think you have a slight misunderstanding regarding this issue.

The actual transaction with the overflow is actually this [1]. It is a valid transaction and for every valid transaction, the inputs has to be mapped to another TXID and in this case, 237fe8348fc77ace11049931058abb034c99698c7fe99b1cc022b1365a705d39:0. There is no extra 0.5BTC that was caused by the overflow incident. The transaction in question generated 2 outputs of 90 million Bitcoins each and it was "reversed" subsequently, excluding that transaction and continuing on the correct chain which doesn't contain any TXes affected by the overflow bug. The Wiki is stating that the 0.5BTC used as the input in that transaction has since been left dormant[2] after the overflow transaction was reversed.

how's that possible?
where did it go?

As written in the linked article, the chain was forked.
This means that the problem doesn't "exist" on this blockchain.
The problem existed on an alternate blockchain until block 74691, then the correct blockchain/fork took over and the other blockchain/fork was dropped.

While the transaction does not exist anymore, the 0.5 BTC that was consumed by it does. It appears to have come from a faucet and has not been used since.[7] "

about the overflow incident:

"The bad transaction no longer exists for people using the longest chain. Therefore, the bitcoins created by it do not exist either. While the transaction does not exist anymore, the 0.5 BTC that was consumed by it does. It appears to have come from a faucet and has not been used since.[7] "
https://en.bitcoin.it/wiki/Value_overflow_incident

does that mean we have 21m+0.5 bitcoin?

No. Look at the transaction in a block explorer. It has one 235,5 BTC input and two (0,5 BTC and 235,0 BTC) outputs. So, unless there were 21m+0,5 BTC before that transaction, this isn't the case afterwards, either.

how's that possible?
where did it go?

with all these huge bitcoin purchases by corporations, i was wondering how many bitcoin is left in ordinary ppl's hand and i made an assumption which ended up w/ this number:

is this method proper for a close guess?

From what OS did you get this error is it from IOS or Android?

It looks like a connection issue. Are you sure that you are not using a fake green wallet?

If you sure that you are using the legit wallet try to update the app and restart the device on IOS. For Android try to clear the cache of that app and reboot the device(Note green wallet from Android is buggy).


If you don't have any funds yet I suggest you switch to other wallets like BRD or Mycelium for IOS and Electrum or Mycelium for Android OS.

yes it's ios. Thanks.

And could u tell me the reason for not using the green?

bitcoin.org was never owned by Satoshi, IIRC.

it actually was.
Martti Malmi says that Bitcoin.org was "originally created by Satoshi." in this 2014 article:

Maybe you can look at the following thread and see if you could extracts some information:

The Bitcoin Origins - Explore Bitcoin History and Secrets

Yeah, that website is already old, been there since 2014, but haven't updated yet.

However, the link that I gave you is up to 2019, maybe you can do your own research and fill in the gaps. Best of luck!!!.

This has been discussed already.

Short summary is that it is (by far) not as severe as outlined by samourai.
The coinjoin itself is secure. No one is able to link inputs and outputs together.

For a more detailed response, read the first page of this thread.

What exactly is your concern?


my concern as a nontechnical person is to come to a acceptable conclusion; which seems to be achieved. I read the thread; thanks Smiley
