Seems that also somebody (may be maliciously) is building very long alternative blockchain. I don't understand why.
Pool at dero.tech, for example, shows constantly extending blockchain with different (lower) difficulties, now its length is 40240 (official blockchain has 40245), seems that it's forked at 40213. Please be aware of that.

If you want us to mine at pool.dero.live, please fix its network issues. They are quite annoying.
