I am not seeing anybody talking about this topic around these parts so let me start.
We have all seen the spam attacks, the huge backlog (100k txs), transactions being sent from one key to same destination with seconds apart and paying small to high fees just to fill the memory pool, transactions using multi-sig and lots of inputs to increase the size of tx (in bytes) to fill the blocks, ...
the problem is, you can't tell which transaction is legit and which is spam attack because how bitcoin works.
looking at this small group of examples:
https://bitcointalksearch.org/topic/mother-of-all-spam-attacks-on-bitcoin-network-proof-1776143also seeing the latest block that was mined:
https://blockchain.info/block/0000000000000000018d332fbb23692fe67dfb941607e870116e2c4edfae668e which contains lots of strange large value transactions (8 to 19
BTC) all having 600 satoshi/byte
was the the last straw leading me to start this discussion.
so what does everyone think?
are the blocks we see full of real transactions or are they full of spam?
how much of it do you think is real and how much spam?
do you have any ideas to finding these transactions and possibly finding the source and hopefully finding the one(s) responsible?
