We’re trying to build on Bitcoin Testnet4, but ckpool is making it nearly unusable. They keep mining blocks with either no transactions or only their own, while ignoring all other incoming txs. This defeats the whole point of a testnet — to test real transactions.

Bitcoin development is already slow. Now we have a miner actively making it worse in the only place where devs can safely build and experiment.

You can see it for yourself — the same address has been collecting block rewards for 2 months:

Sure, earning rewards is fine — it’s part of the protocol. But actively censoring other transactions crosses the line. It’s manipulation, and it’s stalling development.

This is incredibly frustrating for the developer community. Either this gets fixed, or we seriously need a new testnet.
