<p>It is not too difficult to check the low-fee transactions in large blocks with block-explorer. Follow the link

Thanks, this is already helpful. I will not investigate further, it just intrigued me what the intention could be. Indeed, likely spam

<p>When looking at the last hours of bitcoin cash (BCH/BCC) transactions I saw a massive increase in low(or no)-fee transactions:</p>

<p><a href="https://i.sstatic.net/uRMT6.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/uRMT6.jpg" alt="BCH mempool"></a></p>

<p>Usually the graph looks similar to the BTC case (see below), just without the backlog of unconfirmed transactions.</p>

<p><a href="https://i.sstatic.net/ELR4u.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/ELR4u.jpg" alt="BTC mempool"></a></p>

<p>Is anything known who did this and why? Is it just to test out if BCH is able to support high transactions volume without problems (fortunately it seems so, with ~20k transactions per block) or does somebody have malicious intentions and is trying to stall the BCH network?</p>

<p>Have people done similar things with BTC in the past?</p>

Do you have any sense of what these transactions look like?  It could be that some large organization has just realized that the current low-fee environment is an ideal time to consolidate small txouts, rotate private keys, or other sorts of non-critical transactions.

@amaclin gave me good hints in his answer. But I know nothing more about the origin or the initiator(s)
