No, that's 99,9999999% certainly a burn address... It's a valid address, but nobody has it's private key.

If you look at this address in a block explorer, you'll see that the value of the funding transactions is equal to the unspent value (so nobody has ever spent any funds from any transaction funding this addres) => burn address

EDIT: you can create your own burn address using a tool like this one: https://github.com/adamkrellenstein/unspendable (if you don't want to learn the technical details on how to do it yourself). Do realise that it's a BURN address, everything you sent to is is considered BURNED... if you generate one, fund it, those funds are now gone forever...

Nope, no one can crack Bitcoin code.

That's address is called as vanity wallet address or a customized Bitcoin address where you can create a wallet with specific letter, word or number as long as it can be created. You can't expect you can get a long customized address since it's hard to create, you need a long time to spend.

The address OP is referring to isn't a vanity address. Vanity addresses are derived with testing a large number of private keys. So, the owner knows the private key.
No one knows the private key of the address mentioned in the OP and creating an address like that is very very easy. The only requirement is that the address must have the correct format of a bitcoin address and pass the checksum.
It may worth mentioning that creating an address like the one mentioned in the OP with a known private key is almost impossible.

Years ago, in 2015, someone created a list of such BTC burn addresses he was aware of in this post. This other end of 2017 external site includes a longer list, and indicates that 1111111111111111111114oLvT2 was identified as Blockstore’s burn address.

When I looked at this matter recently, I focused more on 1CounterpartyXXXXXXXXXXXXXXXUWLpVr, which is XCP cryptocurrency’s proof of burn address, and I believe is the largest holder of its nature. The story behind this case is interesting, and well worth a read to understand why they burned those BTCs.

In terms of how these addresses are created, I found the following two posts to be rather clarifying:
https://bitcointalk.org/index.php?topic=5123840.msg50282766#msg50282766
https://bitcointalk.org/index.php?topic=5278431.msg55270386#msg55270386

As depicted in the above posts, these type of addresses are created to fit the structure and rules of a public address without being originated from a private key. They is therefore nobody that can actually access the burnt BTCs.

I do have the doubt though of how one can distinguish a vanity address from a burn address, whereby the former will be in control of somebody as (theoretically) opposed to the latter (perhaps the length of the legible part of the public address is part of the answer, but it seems like a simple non-exhaustive criteria).

AFAIK, there is no 100% certain way of telling which is a burn address and which is a vanity address...
This being said, it would take gazillions of years to create a vanity adress depicted above, the odds of finding an address like that within a lifetime are so close to zero that you can safely say it IS zero.

If you see an address like my vanity address: 1MocACiWLM8bYn8pCrYjy6uHq4U3CkxLaa you can easily see the "vanity" part is only 6 characters... If you have a GPU farm and a lot of time, you could probably go to 10 or 11 (i guess, not calculated tough), but more than that doesn't seem feasible.

A second thing you can look for is a block explorer: if an address looking like a burn address was funded with hundreds of BTC over many years, and not a single unspent output was ever spent, odds are big it's a burn address...

Last but not least: any address can be a burn address. If you generate an address without a private key, or you immediately destroy the private key after generation, it's a burn address... But it's kind of hard to prove a "normal" looking address is a burn address... Anybody could generate an address and just say it's a burn address.

You are wrong. If a person could really "crack the code and do what he wants" (which is very, very unlikely), then they would have already spent at least some of the funds from the given address. Or better yet, why not crack some of the addresses that contain thousands of bitcoins, like Binance's cold wallet or some of the other Bitcoin Rich List addresses?

No, what you are looking at is a "burn address" or "black hole" address. It's a valid address, but nobody has their private key to use in order to spend the funds from that address.

[DaveF]

As others have said it is obviously a burn address. The large number of 1 in the beginning just makes it easy to spot. I could just as easily install a new copy of core, copy the 1st address it gave me and then shut it down and delete my wallet.dat file. But it's impossible to prove that.

8 or 9 is about the limit, not counting the 1 at the beginning, that you can do with a sane sized GPU farm. The new 4xxx Nvidia stuff might do better, but it's so power hungry and overpriced at the moment that it's not a real option. Also, some addresses of even the same length are going to be more difficult and take longer to find then others.

This address - 1111111111111111111114oLvT2, created from RIPE160 hash with all zero bits "0000000000000000000000000000000000000000"
Because there is no known attacks on ripe160, it is nearly impossible that someone found such input, that will produce that hash, even if you do not take into account double hashing when generating an address.
To get this address, you have to find a such EC point, that will produce such SHA256 hash, which in turn will produce 160 zero-bits RIPEMD.
So, 1111111111111111111114oLvT2 is valid BTC address, but no one knows its key, and it may well be that such a key does not exist at all.

But it's kind of hard to prove a "normal" looking address is a burn address... Anybody could generate an address and just say it's a burn address.

Exactly this is the main point.
While nobody will believe you that you've thrown away the private key for 1MocACiWLM8bYn8pCrYjy6uHq4U3CkxLaa, it's pretty much unlikely (heh 99.9999999%) that you or anyone can have the the private key of
1111111111111111111114oLvT2, 1BitcoinEaterAddressDontSendf59kuE or, why not, 1JasonBrendonHasMuchToLearnwzf2iV, simply because they are far too long to be vanity addresses.

[BlackHatCoiner]

How the fuck do you create an address like this?

You take any 160-bit number you can think of (from 0x00, to 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF), add a version byte in front of it (0x00 for mainnet), double hash the result with SHA256, take the first 4 bytes of this hash (which is called the checksum), extend your version byte plus 160-bit number with the checksum, and pass this final result through Base58Check encoding.

It's highly likely that it's a burning address. However, any coin sent is not provably removed from supply. There are about 2^96 valid Bitcoin private keys that can unlock these outputs.

If you do that, you'll get an address with arbitrary characters not what you wanted to have like all ones similar to the one OP shared. In order to get that type of address with a large number of predefined characters you need to start backwards meaning from the address itself (the details were posted before).

Here's the thread for the tutorial [Guide] How to create your customized Bitcoin-Address (vanitygen) – step by step

You don't need to make a vanity address if you don't want the private key. Those characters on the right which are not 1, form the checksum - All that guy did is take the bytes that make the character sequence "11111.....", calculate its checksum and then stick it to the right of the address to make it valid. Anyone can do that, but of course those coins will be unspendable because nobody bothered to calculate the private key for it.

I don't understand. Isn't the OP asking how to make burning addresses, just like the address in title?

It is and the method you explained would create a burn address, however the example OP shared is like a subcategory of burn addresses with predefined characters/words like 1BitcoinEaterAddressDontSendf59kuE.

[seoincorporation]

To create an address like that you have to use a bitcoin address validator tool And by creating it you will not have access to the privatekeys, so, all the coins send to that address will be lost.

The tool i use is: https://awebanalysis.com/en/bitcoin-address-validate/

And here the is example of how to use it.

If you find a valid address this way you can use it as a burning address.

Yes but since Base58 does not perfectly fit inside Base2/16, there will be some leftover just like how a single Base10 digit requires 1-5 digits of base2. So you can't just modify a few bits in the hash160 and expect it to change only a single character, it will have a knock-on effect on many Base58 characters.

so you're saying that there are a bunch of idiots sending money to the pit knowing the money is gone forever? Then again, why the fuck do they want to burn money for nothing?

[Sarah Azhari]

Maybe because they think money can't buy happiness. Or, maybe they have lots of bitcoins, it's just like rich people who have a hobby to burn money at the party. So, as I know when someone sends bitcoin to op return that makes the bitcoin supply decrease, which makes the price to the moon if demand increases.

until yesterday, https://www.blockchain.com/btc/address/1111111111111111111114oLvT2
Someone still sends bitcoin to that address.

strange as this might sound, yes, that's what happening.

There are some reasons sometimes... For example there's counterparty: https://counterparty.io/news/why-proof-of-burn/

And you also have to realise 1 BTC wasn't always equal to $20.000. There were times a bitcoin was only worth a couple of cents. At this time people might have done stuff like this just because they felt like it.
