It seems that bitInfoCharts got interested in analalyzing dust in Bitcoin too, they made this link about top100 dustiest addresseshttps://bitinfocharts.com/top-100-dustiest-bitcoin-addresses.htmlIn them u can see this first address, with 1,712,706 UTXOs (ins-outs) https://bitinfocharts.com/bitcoin/address/1HckjUpRGcrrRAtFaaCAUaGjsPx9oYmLaZif u had a fast glance at the address I'll find the real operations with real money are very rare compared to the dust. Is this normal??? Even considering 1 dust UTXO for each lightning TX doesn't explain it. I have been away from Bitcoin new things for a while, is it possible there is some bug that adversaries use through dust or the side chain for lighting networks? Or what? Or u find this normal?

Yes, according to WalletExplorer, it's an address connected with the Huobi.com exchange. The address also appears in Bitcoin's abuse database as being connected to ransomware attacks. It's been reported twice, in 2019 and 2020.

And you still have no way of stopping it till now today 13 Feb 2022? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Wait a minute, but people are not going to pay a few cents as ransome? It could be a hacking method, or just a notify that some real payment happened elsewhere

And you still have no way of stopping it till now today 13 Feb 2022? ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Stop the address from sending or receiving coins? Bitcoin can't be censored that way by anyone. That's a feature of it, not a bug. If I wanted to, I could send you dust inputs every day, how would you prevent that? Wait a minute, but people are not going to pay a few cents as ransome? Ransomware is mentioned in the reports by the people who submitted them. Those don't need to be true though.

I don't see where is "Omni" written in the original address? Just look at transactions. Blockchair can even decode that and show you details related to Omni Layer: https://blockchair.com/bitcoin/transaction/1be33473aa7fd41e75a1d7e3000a45b2ff8e394b486a9534e4a4600ff4146c6b{ "txid": "1be33473aa7fd41e75a1d7e3000a45b2ff8e394b486a9534e4a4600ff4146c6b", "hash": "1be33473aa7fd41e75a1d7e3000a45b2ff8e394b486a9534e4a4600ff4146c6b", "version": 1, "size": 257, "vsize": 257, "weight": 1028, "locktime": 0, "vin": [ { "txid": "ded898b25fa3e536cf4cb2a102488abecc2f3bc2bd0315a74f305fcc6dd5361a", "vout": 0, "scriptSig": { "asm": "3045022100d0808a9222507fc960e77b6ff074f41096e8d553455b938d74098bd87136e48a022020146378fdf43ed7dea3541fee0ea206fa036897c8bd41c77996ef5d269e5c46[ALL] 030651e1d15ae9a284ffd712885529d3344db3700be756e6c22c56a6c1b57d359d", "hex": "483045022100d0808a9222507fc960e77b6ff074f41096e8d553455b938d74098bd87136e48a022020146378fdf43ed7dea3541fee0ea206fa036897c8bd41c77996ef5d269e5c460121030651e1d15ae9a284ffd712885529d3344db3700be756e6c22c56a6c1b57d359d" }, "sequence": 4294967295 } ], "vout": [ { "value": 0.00427136, "n": 0, "scriptPubKey": { "asm": "OP_DUP OP_HASH160 b64513c1f1b889a556463243cca9c26ee626b9a0 OP_EQUALVERIFY OP_CHECKSIG", "hex": "76a914b64513c1f1b889a556463243cca9c26ee626b9a088ac", "address": "1HckjUpRGcrrRAtFaaCAUaGjsPx9oYmLaZ", "type": "pubkeyhash", "addresses": [ "1HckjUpRGcrrRAtFaaCAUaGjsPx9oYmLaZ" ], "reqSigs": 1 } }, { "value": 0.00000546, "n": 1, "scriptPubKey": { "asm": "OP_DUP OP_HASH160 69bb7659642f5217887351e6a9ccbc45ccd0938d OP_EQUALVERIFY OP_CHECKSIG", "hex": "76a91469bb7659642f5217887351e6a9ccbc45ccd0938d88ac", "address": "1Ae4XFaCWSVsxdyGBWArfAepWwa99Lmskx", "type": "pubkeyhash", "addresses": [ "1Ae4XFaCWSVsxdyGBWArfAepWwa99Lmskx" ], "reqSigs": 1 } }, { "value": 0, "n": 2, "scriptPubKey": { "asm": "OP_RETURN 6f6d6e69000000000000001f00000014f540a380", "hex": "6a146f6d6e69000000000000001f00000014f540a380", "type": "nulldata" } } ] } At the end you have "OP_RETURN 6f6d6e69000000000000001f00000014f540a380" and "6f6d6e69" is "omni". The rest are 16 bytes related to the Omni Layer. So you can type the same transaction ID in Omni Explorer and get some details: https://omniexplorer.info/search/1be33473aa7fd41e75a1d7e3000a45b2ff8e394b486a9534e4a4600ff4146c6bEdit: I guess they used 0.00000546 BTC, because it was the minimal amount then, when Omni was created. But if they could use zero satoshi here, then I think they would do that. The whole idea is to get some representation of a token directly on Bitcoin, that is spendable. If you can create zero satoshis on-chain and if it is standard, then you can create tokens and exchange directly between Bitcoin and Altcoin in a single transaction! For example imagine doing something like that: +------------------------------------+ | Alice 50.01 BTC -> Alice 0.00 BTC | | Bob 0.00 BTC Bob 50.00 BTC | +------------------------------------+ Then, "0.00 BTC" can represent for example "1000.00 ALT" and you can atomically trade on-chain. In this case, Alice sold 50 BTC to Bob for 1000 ALT. Your idea of destroying or moving small coins somewhere else can break such things. You would think you destroyed 0.00000546 BTC, when in reality you would destroy also some altcoins or other tokens you know nothing about. Also, your idea means using zero satoshis will be impossible or pointless, so that would break many future protocols (like fractional satoshis on-chain, NFT's on Bitcoin, atomic trades between tokens on Bitcoin, etc.).

Wait a minute, but people are not going to pay a few cents as ransome? Ransomware is mentioned in the reports by the people who submitted them. Those don't need to be true though. With only 2 report, where one of them say "I can help u", the report is far for reliable. Edit: I guess they used 0.00000546 BTC, because it was the minimal amount then, when Omni was created. But if they could use zero satoshi here, then I think they would do that. The whole idea is to get some representation of a token directly on Bitcoin, that is spendable.

For better or worse, UTXO is 0 satoshi isn't possible. There are few concern with 0 satoshi UTXO which mentioned here https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-December/019637.html.

There are 1.7m extra dust UTXOs, resulting from about 3.44m real transfer. 2-What you say means that your protocols/plans are more like non-standard transactions that just want to be attached to Bitcoin and that you people are planning to increase the dust memory overhead of UTXOs to higher ratios than now (~ 7%less than 1000 Sat, ~10% less than 1$, 17% less than 4$)

here there is no corresponding valuable UTXO for each dust one? It depends how you will define "valuable". Zero satoshi simply means "skip amount validation for old nodes". It can be treated as a valid, non-zero value on another chain. So, "valuable" depends entirely on the chain that is stored on Bitcoin. If it is valuable (on another chain), it will be spent. If not, then it will be left untouched. you people are planning to increase the dust memory overhead of UTXOs to higher ratios than now Sometimes you simply don't want to attach any value to some UTXO. Things are simpler and cheaper where you have zeros. It can be seen clearly on testnet, where you can just use zeros, use nonzero amounts to pay for fees, and assign any values in your software. Also, some UTXO's should have zeros, because for example if you have some NFT, then you want to assign zero, to show that no monetary value is attached into it and it is entirely separated, and there are no coins involved, you have just some token and some owner of that, determined by the Script. Also, I have some other questions: imagine that zero satoshis (or just dust amounts) will be invalid (or distributed automatically to miners). Then: 1) How to represent things that should not have any monetary value? For example NFT's? 2) How to create fractional satoshis when they will be needed? You would have 0.493 satoshis, how to store that on-chain if it would be $493? 3) What amount should be put to outputs, where that value will be known later? For example, in decentralized mining you don't know how many coins should be received by each miner, when UTXO's are created. You know that after collecting all of them and getting enough confirmations. Edit: 4) What if Bitcoin community will ever want to move to Monero-like system and hide coin amounts? Putting zero in that case seems to be a good choice. After your proposal, this change will be rejected. If you want to get rid of dust UTXO's, then I think you should put an incentive for those who will do that. So, something like fees based on UTXO consumption and creation could work better than taking UTXO's by force. In this way, you can still have such outputs, but they will be more expensive (for example if you could pay 0.5 satoshis per byte for consuming a lot of dust inputs, then some people may start doing that).

It's the USDT Omni wallet for an exchange. https://www.omniexplorer.info/address/1HckjUpRGcrrRAtFaaCAUaGjsPx9oYmLaZNot malicious and there are a bunch of non dust UXTOs in there too. Don't see what the big deal is, there are a lot of other wallets with similar inputs & outputs that are part of other exchanges. Personally I would be doing it a bit differently if I was running an exchange, but if the back end programming works and works well running it this way then it's not a big deal. Well, that and not using USDT or Omni in general, but that is not the point here. -Dave

For a start before the rest of points an NFT could be represented by its money worth value, that even make sense And what is worth? Prices in free market are constantly fluctuating. You state that an NFT is worth 10,000 sats and whoever takes it, takes the sats, right? 2) How to create fractional satoshis when they will be needed? You would have 0.493 satoshis, how to store that on-chain if it would be $493? That's a big if. Even if the whole world got into Bitcoin, taxes, stocks, real estate, bonds etc., if everything was calculated in BTC, it'd be unusually unhealthy economically for 1 sat to worth so much whether the dollar had been hyper inflated or not. In such crazy scenarios, here they come the hard forks.

The intention of these transactions is not to transfer bitcoin, but rather to transfer a token via a layer 2 protocol. I don't think the entity that owns the private key ever plans on (attempting) to spend any of the UTXO sent to this address.

No I don't think it's a burden. Neither do any of my RPi nodes nor does the 10+ year old 1st gen mobile core i5 laptop that I just setup following this guide: https://bitcointalk.org/index.php?topic=5366854.0If old and or slow hardware with limited RAM and old drives can handle it with no issue, then there is no reason to worry. Even if that number goes up by 3x or 4x by the time it does, 'scrap' hardware will be 4th gen i3 and 1TB SSD so I really don't see an issue. -Dave

I suppose the good news is that Bitcoin has a hard limit on the maximum number of dust UTXO that it will allow to be created. Therefore, this "dust UTXO" situation will eventually have to stop.
I think the limit is a bit below 2099999997690000 ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

I suppose the good news is that Bitcoin has a hard limit on the maximum number of dust UTXO that it will allow to be created. There is no such limit. If you are a typical user, you have to obey this dust limit. But if you are a miner, then you can create and move UTXO's with any amount (including zero satoshis). That means, you can burn all coins and create zero satoshis out of thin air, the number of UTXO's is not limited by consensus. You can try it out on regtest, there you can mine any test blocks with a CPU, because it has enormously low difficulty. Also note that in the past everything below 0.01 BTC was considered a dust (and that limit was lowered without any forks or consensus changes, it is executed on node level and each node can create its own rules or stick with default settings). If a single satoshi will be worth some significant amount, then I think that dust limit can be lowered to one satoshi per kilobyte, per megabyte, maybe per transaction or per "(created*2)-consumed" outputs, we will see.
