Whats the current state of testnet3 vs testnet4?

[BlackHatCoiner]

Easier to mine a block with real difficulty than with difficulty 1.

At least wipe out all CPU-blocks mined before your block if you do that.

Seems like SoloPool.com started applying this: https://mempool.space/testnet4/block/0000000000000001b36fc5289b8441e8d298d0a4bcb6892665c2a13a0a4b5bfa.

I can't really tell if they wiped out blocks from this data.
It looks like they're just mining CPU blocks by themselves, then their ASIC block secured their own CPU blocks. Look at block 160104 for example: there's a row of SoloPool blocks, but they're all CPU blocks.

Yes, that's what I meant. I have neither observed blocks being wiped out. In fact, in this block, the SoloPool miner clearly did not wipe out the three CPU burst-mined blocks after the latest ASIC block of the time, when it could have done it.

In other news, testnet5 is soon launching: https://stacker.news/items/1611539. The genesis block will commit to mainnet block 975,744, which will be mined roughly in the 13th of November, 18:00 UTC.
