There’s an ongoing attack on Monero network, for further details read the following article: https://sethsimmons.me/posts/moneros-ongoing-network-attack/
TL;DR Someone deployed ~130 monero nodes to try halt the network. However Monero has more than a thousand nodes so the attack has no success for now.
Now back to Zcash.
Based on blockchair explorer there are 140 nodes running the network: https://blockchair.com/zcash/nodes
Firstly, I wonder if this figure is correct?
If so, then a similar attack would halt zcash network.
Actually I’m surprised that zcash has so few nodes.
If all the above is correct and if I’m not missing something, then it’s crucial to start educate people to run zcash nodes. And deploy more trusted nodes from ZF, ECC and other trusted Zcash entities.
