I build a python script to talk to bitcoin test nodes. When I'm sending mempool messages, my connection is getting is reset. Also sometimes when connecting to Jimmy Song's testnet node (testnet.programmingbitcoin.com) I get and an inv message back, other times my connection is cut after sending a mempool message.

What's going on here? Is mempool mostly unsupported on testnet nodes?

  • I've got a hunch only nodes with services 1036/1036 allow mempool messages. Nov 4, 2021 at 18:14

    It’s just not supported on modern nodes, it serves little to no purpose for anything other than abuse.
