When crunching blockchain data, my script tripped up on transactions without any outputs (vouts). Is this Monero's equivalent of OP_RETURN script, or am I missing something?

After looking at some examples in a blockchain viewer, it appears that the value of the outputs goes to the miner, I will leave the question open for good suggestions as to what is going on there:

Block 761388 Block 782656 Block 844741 Whole block 1006680

  • Can you tell us the txhash or block height of such a transaction?

  • This is a recent example - xmrchain.net/tx/…

  • Wow, I'm really surprised by that.

  • Note that, for all transactions, the sum of the inputs is equal to the fee. Thus, the output is going straight to the coinbase reward, which is a different transaction.

  • @dEBRUYNE What's odd is that after following the link to the transaction in block 761388, if the containing block is examined, the no-outputs transaction is not listed. Only a different miner reward transaction is listed. I assume this must be a bug in xmrchain?

Monero has no scripting language. Even though the Cryptonote paper describes a simple lightweight one, the code did not implement it at the time Monero forked.

  • You missed the point of the question - I'm not asking about Monero's scripting capabilities. If you are not familiar with BTC, OP_RETURN script means that the transaction is unspendable, provably so. Although this doesn't appear to happen here.

  • Transactions are neither spendable nor unspendable, that does not make sense. A transaction consumes inputs, and creates outputs. In Monero, it's the same. Inputs are consumed, and outputs (possibly none) are created.
