Mempool.space block explorer offer auto complete when you doesn't type whole address. You'll have look elsewhere for different coin though. And most importantly, those https://i.ibb.co/NtZ6y1x/f.png Title: Re: Short Adresses , how to check it? Post by: NeuroticFish on December 14, 2022, 02:16:40 PM Also walletexplorer.com, while I don't recommend it as a block explorer to use, it's good at finding addresses based on "firstbits".
For your bitcoin address it returns this: https://talkimg.com/images/2023/05/14/blob0155684a10ab4a78.png Title: Re: Short Adresses , how to check it?

Keep in mind with the shorter ones people with enough computing power can generate them with a little work and time 1EEoqxSat3 followed by the rest of an address can also be 1EEoqxSat3 followed by the rest of another address with less then a months worth of GPU computing power. And with all the GPU rigs not doing much after ETH went PoS there are a lot of them out there not doing much. Also I have noticed at times when using walletexplorer.com, it will give the 1st address of what it finds not all of them. There are a lot of 1nasty addresses but it does not show all of them. -Dave Title: Re: Short Adresses , how to check it? Post by: Charles-Tim on December 15, 2022, 01:37:18 PM Is there any good reason to be looking for complete character of an incomplete addresses? If you have your seed phrase or private key, they can generate your complete address anytime that you want it.
I have seen people on this forum looking for some missing characters of a private key, or how to decrypt a BIP38 encrypted paper wallet private key, or looking for some missing words of a seed phrase. Those are normal for obvious reasons, which is to be able to access the private key to spend the coins in connection with them. how can i check short crypto adresses? Is there any good reason you are looking for a way to make the incomplete characters of an address complete?Title: Re: Short Adresses , how to check it?

If you have your seed phrase or private key, they can generate your complete address anytime that you want it. In these cases the private key tends to stay hidden under a seal. That's because short addresses/firstbits are useful for collectible items, usually coins, where the space is very limited. And people still want to check whether the collectible they've bought is indeed funded. Title: Re: Short Adresses , how to check it?

The problems are as I said the fact that without 10+ characters of the address it is easy to generate another address with the same visible 1st bits. Even if you have the complete address do you know what is really under that hologram: https://bitcointalk.org/index.php?topic=5401502 And the ever popular you don't know if you can really trust the coin manufactures. When BTC was $400 if some maker made 100 BTC0.1 and ran off with 10 BTC it sucked we all got pissed and went on with our day. Now even at the $17000 price it starts to get into substantial amounts of money. Relying of 1stbits and holograms and so on is just no longer viable. -Dave Title: Re: Short Adresses , how to check it?

Now even at the $17000 price it starts to get into substantial amounts of money. Relying of 1stbits and holograms and so on is just no longer viable. That's true/correct. I've read already about manufacturers getting silent and having the coins redeeming logic based on their (now offline) website. I think that I've read about the possibility holograms could be taken down and put back again (in some cases). Clearly, addresses created with the same firstbits in order to mislead users is not a possibility to dismiss. Imho collectibles are very nice even if not funded (I tend to like more the DYI ones). Funded collectibles, especially with higher amounts, tend to pose unnecessary risks. So, again, I agree, you're fully right. However, the topic has started with a question, not a debate on how (un)safe holograms and fistbits are. If one indeed has such a collectible, he will still want a tool to see his funds without taking down the hologram. Yes, it may not be accurate, in some cases the wrong address may be returned/checked, but I don't know of better tools. Title: Re: Short Adresses , how to check it?

Not exactly tool, but you could download list of funded/used address and find address based on "firstbits" either using text editor or grep command.

Like: LbWKXCVe for LTC 1EEoqxSat3 for BTC 0xF22c60 for ETH All blockchain Explorers that ive tryed dont work anymore with this short addresses... This is an explorer website that will give you information what are your seeking. And I am using it from almost 2020 and it helped me a lot in many ways. You will also learn many things in your life cause more you seek more you learn. https://i.imgur.com/KjuTM9a.jpeg Title: Re: Short Adresses , how to check it? Post by: DaveF on December 17, 2022, 02:55:12 PM .... Yes, it may not be accurate, in some cases the wrong address may be returned/checked, but I don't know of better tools. Sorry I didn't put it clearly, it's not that there are no better tools, it's the fact that there are no tools or even a way to be sure. If you can't see the full address and the private key so you can verify that the private key is actually, for that address, while making sure nobody else has seen / still has the private key then you no longer have BTC. You have a lottery ticket that may or may not have BTC in it when you finally scratch it off.

To be more thorough, you shouldn't only check currently funded addresses, but all addresses: http://alladdresses.loyce.club/all_Bitcoin_addresses_ever_used_in_order_of_first_appearance.txt.gz (it's a slightly larger download (27 GB)).Code: $ wget http://addresses.loyce.club/Bitcoin_addresses_December_16_2022.txt.gz I've just checked for 1EEoqxSat3, and it only shows 1EEoqxSat3Tg6LkwEYxwHgQUtmHVn8uKwc. For Litecoin (https://gz.blockchair.com/litecoin/) and Ethereum (https://gz.blockchair.com/ethereum/) you can download the full data too (if you're patient enough).

Post by: LoyceV on December 18, 2022, 12:45:28 PM But what you said above is interesting, for you the acceptable limit of a shortened address should be 10 characters at least. I see no point in shortening anything. It requires trusting a third party, while I'm using Bitcoin so I don't have to.Quote Address strings shorter than that are such risky? I mean 7+ characters is not enough according to you? Are there some figure (stastistics) about that somewhere? I did a quick check of currently funded addresses. These are the most common "firstbits":Code: 533 13vs7FtkinfdQEr Update: I checked the same for all addresses ever used (including empty ones), and only 1h8BNZkhsPiu6EK has an empty address: 1h8BNZkhsPiu6EKazP19WkGxDw3jHf9aT (http://loycevu3e75xlfrdxqueln6mk2dl2ditaqohpxgc35k2jezww6sxs4qd.onion/address/1h8BNZkhsPiu6EKazP19WkGxDw3jHf9aT) If that was your "firstbit" address, there are 16 fakes out there: Code: 1h8BNZkhsPiu6EKazP19W8qdEN1T3b8Yb Title: Re: Short Adresses , how to check it?

You have to trust whoever is generating the keys that they are not keeping a copy of the private key. If you trust them, then past that then 10+ should be fairly safe from someone duplicating them. Some coin makers give a complete address list, those should be safe (eliminating the hologram peel / replace) others do not. https://bitcointalk.org/index.php?topic=2022902.0 For other things it really becomes a matter of trust vs amount. I am more likely to trust that someone did not bother to scam me for BTC0.01 then a BTC1.0 But for now I really can't think of a reason to use 1stbits anymore. -Dave |
