This is history question, but one with clear answer.

I would like to know when(txid) was first transaction with fees ? From my understanding in beginning there was more space than transaction so there where no fees.

Additional, if anybody knows, block when at least 50% of transactions had fees ? Maybe this is better metric, because probably somebody has done some transaction with fee on main-net for fun/test.

The first block with transactions that paid fees was block 2817, the second was 12 983. To answer your question, I used blockchair.com’s block overview, sorted the blocks by ascending height and filtered for a fee of at least one satoshi.

The three transactions that paid fees in block 2817 were:

I don’t have an immediate way to answer the question about half the transactions paying fees.

    Incidentally, the first block with over 50% of transactions paying fees is also block 2817, because the three transactions are the only transactions in that block (except for coinbase). May 12 at 14:32
  • Touché, you’re right. I guess I just automatically extrapolated the question to mean the first full block that had 50% txs paying fees, but that was in fact never asked. :)

  • @Murch "block when at least 50% of transactions had fees ?", my idea was to know when at least 50% of transaction had to pay fees to be included in block and never went under 50%. But then I should also add that block need to be full and it is getting complicated. To get some idea when fees became "mandatory". But it is not so important.

    Maybe this will help: transactionfee.info/charts/fees-package-feerates/…, the chart seems to show that a 50th percentile for feerates appeared end of 2010.
