fortelenYea it can be done. a chain can switch between UTXO and account model but it is a big job not just a do it quick thing. You would need a major protocol upgrade and migration logic. totally can be done just heavy engineering and pain lol
It is not even worth mentioning how stupid and generic this post is. He bumped a thread that had no replies since January 27, and when combined with the idiocy of his post it is clear that this was solely done in a desperate attempt to raise his post count. @ABCbits this time I expect strictness, it is after all in the appropriate section.

I was too lazy to make report, but you gave me reason to do it. On related note, i also notice some account have changed their tactic from blindly copy/pasting AI generated text to creating generic/rephrased post.
I wish that the forum had section-bans and that a new moderator could be assigned for the technical boards. With this spammy users who for whatever god forsaken reason of leniency don't deserve a permanent ban could be issued permanent section bans.
The forum doesn't have such feature. And IIRC it only happened once, see
Note: franky1 is banned from the this subforum.

can a Blockchain move from utxo to account model? or opposite ?

Unhelpful, because it's generic and other member already give more detailed answer.
Why are all the `genesis.hashMerkleRoot` values the same in the Bitcoin network, yet the `consensus.hashGenesisBlock` values printed are different? How is this implemented?
The Merkle root in the genesis block is just the hash of the single coinbase tx — that’s why it’s always the same.
The genesis block hash (hashGenesisBlock) is different per network (mainnet, testnet, regtest) because the header fields like nTime, nNonce, nBits are different.
So same Merkle root + different header → different block hash. Simple tweak in header fields makes each network unique in its own way.

1. Some points already mentioned by other member.
2. You can create Bitcoin TX safely using application other than official Ledger app.
3. If the device isn't genuine, it's likely all of the Bitcoin already hacked and OP would ask why his Bitcoin got hacked in first place.

hey,
can’t help with anything shady or ransom-type stuff. if you’ve got legit encrypted data, best move is proper recovery/legal routes, not btc deals.
stay safe.
1. The implication of "shady or ransom-type stuff" doesn't make much sense when the one who asked question give very few details.
2. Legal route wouldn't help with encrypted data, unless it somehow use backdoored encryption and government would expose the backdoor existence just to help one person.

Bitcoin node usually store whole or partial blockchain, so the claim "from the *Node's validation perspective*, the trace is gone" and "The node forgets, but the chain remembers." are wrong.

2. OS choice matters, especially with limited RAM. Some OS use less RAM, which means you can allocate more RAM for Bitcoin Core.
3. Without changing the hardware, you can't run unpruned node. Bitcoin blocksize is bigger than 500GB.

Why are all the `genesis.hashMerkleRoot` values the same in the Bitcoin network, yet the `consensus.hashGenesisBlock` values printed are different? How is this implemented?
They all contain same transaction, which is the coin base. That's a reason why they are same.
The difference in consensus.hashGenesisBlock values printed is attributed to the block header fields that are differently set for each block chain.
Why are all the `genesis.hashMerkleRoot` values the same in the Bitcoin network, yet the `consensus.hashGenesisBlock` values printed are different? How is this implemented?
The Merkle root is the same because the genesis block contains the same single coinbase transaction on all Bitcoin networks. Since the Merkle root is derived only from the transactions, it does not change.
What differs is the block header. Each network (mainnet, testnet, regtest, signet) uses different values for fields like nTime, nBits, and nNonce. These header differences produce different block hashes, which is why consensus.hashGenesisBlock is not the same.
In Bitcoin Core, this is handled by creating the same transaction and Merkle root, then varying the header parameters when constructing the genesis block for each network.
You're on point. The block header fields such as the nTime, nBits, etc. are what changes accross mainnet, testnet, regtest and signet. The effect of this is the genesis block hashes. Also, the difference in hashes are what enforce separation of networks.

Digging on Shor’s Algorithm, I have come to a conclusion that it remains a major threat theoretically. In solving curve discrete logarithm issue which it is capable of, it allows deriving keys privately from public keys that are exposed in vulnerable addresses like older P2PKH, P2PK that are reused, or Taproot spends. This put a high amount of BTC at risk from a harvest now, decrypt later attacks. The amount is estimated to be 6+ million BTC. You can see how huge that is when converted to dollar using the current price. The point is, Shor’s algorithm is a threat.
1. Another user already explain what's wrong with this thread on
https://bitcointalk.org/index.php?topic=5571797.msg66308078#msg66308078.
2. Bitcoin does not use encryption cryptography. So statement "harvest now, decrypt later attacks" doesn't make much sense.
