Oh, to get the 6.11 kernel you also need to add the unstable repos to /etc/apt/sources.list

```

deb http://deb.debian.org/debian/ bookworm main contrib non-free non-free-firmware

deb-src http://deb.debian.org/debian/ bookworm main contrib non-free non-free-firmware

deb http://security.debian.org/ bookworm-security main contrib non-free non-free-firmware

deb-src http://security.debian.org/ bookworm-security main contrib non-free non-free-firmware

deb http://deb.debian.org/debian/ bookworm-updates main contrib non-free non-free-firmware

if you really want to update all packages, I went this route before (and broke my node), but figured out what works. Add this to /etc/apt/preferences.d/pins

then run 'apt update && apt upgrade'

note: do this in the chrooted environment

note2: this will also update the kernel to 6.11

```

nah, this is the result of BIP94 (activated on testnet4), we are in a difficulty adjustment and need to find a block with difficulty > 1. No miner has found one yet.

I have enough to play with for years :-). Thanks though!

haha! not much grafana/prometheus content out there yet for BitAxe yet I suppose. The dashboard I showed here is in my PR in that repo.

Final result:

I'm watching it closely, very curious how this evolves :D We also need more wallets and lightning implementations supporting testnet4 (looking at you LND!)

I think I read somewhere (no clue where), that 2 hour was chosen arbitrary. But it must be at least an hour (+ a little bit) to allow for node operator clock issues related to daylight saving time (+/- 1 hour).

Not sure if testnet could be indicative of what happens on mainnet (security budget wise). Because there is no financial incentive on testnet, miner game theory is quite different between those two.

Just thinking out loud:

Would a testnet without 20 minute rule work, now we have a lot of 'hobby' miners also? Maybe not, because difficulty stays too low, and an adversarial miner with enough hashpower can cause huge reorgs.

What if the difficulty adjustment would not take into account difficulty 1 blocks, and increases/decreases relative to the previous difficulty. I think this makes 'fair' mining using an asic easier, but blocks will flow in much faster than 10 minutes.

Thank you nostr:npub1s9cyrzaj9rwt7kever592np0aehyjxhl6am5ak3lhdwshny9mnyqmkp75j and Horologger for packaging, and to everyone who side loaded for testing.

Source code: https://github.com/Start9Labs/albyhub-startos/releases/tag/v1.10.1

Alby hub instantly the most popular app on StartOS. Great job nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm!

I don't think its a matter of attacking/defending testnet. The root cause is the '20 minute rule' active on testnet3/4. This can be abused (spoofing timestamp up to 2 hours), but it's there for a reason: to not stall the entire chain. Coins have no value, so normal miner game theory doesn't apply, because miners come and go while testing their software/hardware. If there was a better alternative to the '20 minute rule', we can just launch a testnet 5 with different (better?) rules.

yeah, lots of future timestamp fuckery going on. At least testnet4 requires one asic block per difficulty period, that at least prevents the blockstorms like on tn3.

I'm keeping an eye on haven development and might create a StartOS wrapper for it (when I have some time off). Might be after StartOS 0.3.6 release, so I don't have to do it twice :)
