the bitcoin application directory seems to be also very big... now i'm confused, i was thinking the bitcoind saves all its volatile data in ~/.bitcoin [data] - not in ~/bitcoin [application]

Inside the VM, what do you get if you type `ls -l ~/.bitcoin`?

(Now the VM was completely fu**ed up, because 0.0gb left)

Seems easier to rename the file than to change its permissions?

I guess, but the point of this PR is that `change_cost` no longer needs to be set to 0 to indicate that no change is being created.

Yes that might make more sense, I've tried to do such in [f278ac9](https://github.com/bitcoin/bitcoin/pull/30195/commits/f278ac9f78b802e578ad35fd756ddbce229364d4)

Unfortunately, we don’t have the `change_fee` or `feerate` readily available in the BnB function. The following passes the tests, though:

```cpp
- result.RecalculateWaste(cost_of_change, cost_of_change, CAmount{0});
+ /* Calculate the fee for a P2WPKH change output */
+ if (utxo_pool.at(0).long_term_fee) {
+ const CFeeRate feerate = utxo_pool.at(0).m_long_term_feerate * (utxo_pool.at(0).fee / utxo_pool.at(0).long_term_fee);
+ const CAmount change_fee = feerate.GetF

> > I missed that before, but the improved text on the BIP made me realize. It looks like an attacker could jack up the difficulty by mining a few difficulty periods with an ASIC and then stop after the last block in a difficulty period. The network would then be on a difficulty some 4n higher than before, and stuck looking to mine a first block at full difficulty.

I have adopted these changes with minor edits and that addresses your previous comment about the genesis behavior as well.

📝 mzumsande opened a pull request: "validation: Improve, document and test logic for chains building on invalid blocks"
(https://github.com/bitcoin/bitcoin/pull/30207)
Some improvements with respect to invalid blocks and blocks building on them:

1.) The fields `m_best_header` (best header irrespective on whether we have the full block or not) and `BLOCK_FAILED_CHILD` (BlockStatus saying that a header descends from an invalid block) are populated on a best-effort basis and can sometimes be off. This is not too bad because critical consensus code doesn't rely on either of these, but it is kind of brittle, especially because this is not clearly documented. Do
