If external access is required then those parties are given restricted access
So a human needs to get involved.
inappropriate actions were taken by them and need to be reviewed/reversed.
Lack of finality slows processes.
These are solved problems and blockchain adds nothing there.
Two improvements/use cases given above.
The only case that blockchain helps is in a system where you have a large number of random participants
I.e. Access without human authorisation
and you want transactions to be enforced
Finality.
This is why cryptocurrency has been the only practical use case for blockchain,
Supply chain tracking
Royalty payments
Renewable energy tracking
Ticketing
Etc.
A human only needs to get involved for manual database changes. The vast majority of database transactions are carried out by code. The same would be true for blockchain. Again, it’s not magical. I will ask you once again: how do you think a blockchain would be used to improve this? The blockchain as used by bitcoin allows everyone the same access, but uses compute power as a consensus mechanism in the hopes that statistically most participants would be running the same code to keep things legitimate.
How do you propose a bank does this internally? You’ve yet to answer this question I asked a few posts before and instead opted to list proposed use cases like a brochure advertising blockchain. This is what I usually see with blockchain evangelists, repeating talking points that they themselves don’t understand. Like seriously, what is “renewable energy tracking” supposed to mean?

So how would you on-board a new user?

Transactions yes. Access no.
how do you think a blockchain would be used to improve this?
Access is controlled by public key and security is self administered. No central authority chooses who can join.

Exactly. The power of public/private key cryptography.
uses compute power as a consensus mechanism
Compute power is not required for blockchain and has nothing to do with private keys.
How do you propose a bank does this internally?
Issue private key management software to all employees. Get them to generate public keys. Use a protocol that doesn’t require PoW.

“Security is self-administered” through magic, huh? No central authority chooses who can join, which is an aspect that I’m sure a bank would love for their private internal database (this is sarcasm by the way)… “the power of public-private key cryptography” is something you clearly don’t understand. Are you aware that you used “the power of public-private key cryptography” to visit this site over HTTPS and that it had nothing to do with blockchain? Public/private key cryptography is a tool used for many different purposes and by itself has nothing to do with access.
Compute power is what bitcoin still uses and how it regulates transactions. I didn’t say it’s required by blockchain, I gave it as an example of how consensus is reached. The other common method is proof of stake, but that still doesn’t make sense in the context of a completely internal database. Who is staking, what are they staking, and how does that prevent fraudulent transactions in a bank’s internal database?
I looked at the energyweb site and it’s marketing fluff. When it comes to tracking things on blockchain, once you cross the physical-digital barrier, you end up having to use trust. So you want to verify that the electricity you got is renewable? Well you have to trust the entity that gave you that electricity because the blockchain will only verify that you made a transaction with them and that they made transactions with others (e.g. suppliers), but it will not verify the good/service itself (in this case, electricity). I can send electricity your way which was generated by a gas generator, but how could you tell this from the blockchain? The answer is that you can’t, you can only tell that I have made a transaction with you. The smart contract will include a trusted entity which tracked the electricity being sent which the smart contract can look up that the value matches the agreed-upon value. Again, none of this verifies that the electricity is renewable, you are relying on plain old trust.
