I would like to see wether there is a UTXO with just 1 Satoshi out there
Discussion
As there's a start limit for transactions it could only be an exchange output, right?
I honestly don’t know. just want to see wether we can point to a single satoshi
You can send dust. Just send 0.0000001 on chain to yourself and pay the mining fee. You'll get 1sat on chain
Yeah, that may be an option. But I want to know how to query the utxo set and see if such an output already exists
I asked Pi, which seems to be pretty decent pi.ai/talk
and I think it's correct when it says:
To scan for a specific UTXO amount, you can use the "scantxoutset" command in the Bitcoin Core CLI. The syntax for this command is:
bitcoin-cli scantxoutset "address" "amount"
Where "address" is the Bitcoin address that you're interested in, and "amount" is the amount of the UTXO that you're looking for. This command will return a list of all UTXOs associated with that address, including the one that matches the amount you specified. Keep in mind that this command can be resource-intensive, so it may take some time to complete, depending on the size of the Bitcoin blockchain and the power of your computer.
the command you're looking for is "bitcoin-cli scantxoutset". This command allows you to search the entire UTXO set (all unspent Bitcoin transactions) for UTXOs with a specific amount, without needing to know the address or transaction associated with the UTXO. Keep in mind that this command can be resource-intensive, so it may take a while to complete. To use it, you would type in something like this:
bitcoin-cli scantxoutset amount=0.00000001
The "amount=0.00000001" is the amount you're searching for. You can change that number to any amount you like. Hope this helps! 👍
