Why is this transaction won't be propagated to all nodes? #127

Describe the issue

I made a transaction with this payload:

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

The problem with it is that if I rely that transaction to a node, that node accept the transaction, but it will never be propagated across the network. For example I publish it with https://bitcoincash.blockexplorer.com/tx/send then it's available on blockexplorer indexer: https://bitcoincash.blockexplorer.com/tx/aaf36a5b17d6071a3d1e96f5cd26d83ccccde9c0e1a1e48bd465635281724b6f

But it won't be found on blockdozer.com.

Can you reliably reproduce the issue?

Yes

If so, please list the steps to reproduce below:

  1. Rely the transaction above on a node
  2. Wait for some time for it to propagate
  3. Check for that transaction in mempool of a second node

Expected behaviour

The transaction is available in the mempool of a second node

Actual behaviour

The transaction is unavailable in the mempool of a second node

What version of bitcoin-abc are you using?

Bitcoin ABC:0.16.1(EB8.0; bitcoin-abc)

Machine specs:

Not relevant because it happened with all the nodes I know off.

Your fee rate is just below 1000 sat / KB (*) , which is the default setting for minimum tx relay fee rate (mintxrelayfee) in ABC nodes. So most Bitcoin Cash nodes with default settings will not relay this.

But you must have had luck getting it into the mempool of a miner, since it is now in block 506403.

FYI, I tried to submit in https://pool.viabtc.com/tools/BCH/broadcast -> "Raw transaction send failed."

(*) 0.00000988 BCH / KB (rounded)

Thank you. I’ve just realized it recently as well. On Mon, Dec 4, 2017 at 6:38 AM freetrader notifications@github.com wrote:
