somewhere I did read that better strategy is to offer paying some extra TIP in sats.

I am blocking only on DNS level. I am running unbound on my opnsense router and blocking based on adguard and steven black list. I am using that for all networks for home so not only for kids.

is there some mining pool running knots or has restrivtive mempool?

problem is that you filter out big dump jpeg from your mempool, but if it accepted and mined it will be in block THEN you will have to have it on your computer, it will be in blockchain.

trying to read second part again and again, trying read @DarthCoin comments and I am still confuse

my node serve these services bitcoin-cli getnetworkinfo

"localservicesnames": [
    "NETWORK",
    "WITNESS",
    "COMPACT_FILTERS",
    "NETWORK_LIMITED",
    "P2P_V2"
  ]

I think that NETWORK_LIMITED is there because I have maxuploadtarget=512M

NETWORK : This indicates your node is a full node participating in the Bitcoin P2P network. It serves and relays the full blockchain data and transactions to other peers. Other nodes connect to it to download blocks and transactions. This is the baseline service that makes a node a full validating node on the network.

bitcoin-cli -netinfo show this table

         ipv4   onion     npr   total   block
in          0       0      17      17
out         2       8       0      10       2
total       2       8      17      27

I dont know why but all 17 incoming connection over TOR are listed in column npr. But I want to show that I have incoming connection and believe those nodes can download from my node blocks (well max 512M for day), yes only TOR nodes can connect to my node. And you can see that my node connected to 2 clearnet nodes and believe those can also download blocks from my node.

I think that doesnt matter if connection is inbound or outbound, your node is relaying / sharing blocks.

reading https://bitnodes.io/what-is-a-bitcoin-node/#reachable-vs-unreachable-nodes

"... node is considered as a reachable node if it accepts incoming connections from its peers..." I think any incoming connection, whether via clearnet, tor, or i2p, counts.

also : While the Bitcoin peer-to-peer network requires reachable nodes to allow new nodes to bootstrap themselves, unreachable nodes do not negate their importance as they still form part of the Bitcoin peer-to-peer network and enforce the same consensus rules through their outgoing connections.

there is also listenonion=1 which I am using and when I check upload and download then I see more less same amount data

hard to say how interesting it will be for your daughter. saying in other words, dont know what is their method to teach kids. Those modules looks ok to me.

Scratch is very good, I did some projects with my kids and it was quite fun :-) and I find out they are different and you need to take different approach to teach them.

raspberrypi learn page is very good starting point too. You can find a lot of scratch projects. They have also 3 chapter :

Check it out with your daughter :-)

how many days you plan? those are big old city with a lot of "interesting" places.

you can find my post from all of them ;-)

it is a stork ;-)

Well, photos from are taken by phone trough window so there are not so nice. I did used fuji camera in cities ...

if you like hills then slovakia is better choice. you can check my post about biking trip #1015077 or post about visiting budapest #763855
