(which means human readable and related to the actual information which makes them easier to remember)

These actually are the most important features.

Example: transaction references not related to the actual subject of the transaction (ie. what is being paid for) is enabler for MITM scam schemes.

> Short is convenient

Nah. Short is crucial for identifiers to be effective for computers to handle (memory and CPU efficiency). Otherwise we wouldn't need any identifiers and would just pass raw data around.

> * versioned - Versioning is only interesting because you’re trying to derive from real data.

Nah. Even UUID formats contain version information.

> * easy to index - Sure.

> * sortable - Nice to have at best.

These are directly related (and in the context of UUIDv4 vs UUIDv7 discussion sortable is not enough - we also want them to be "close" to each other when generating so that they can be indexed efficiently)

You keep saying that but you have provided virtually no evidence in support of this. This is why I called your claim philosophical. You are asserting this as fact and arguing from that standpoint rather than considering what is the best based on actual requirements and trade offs.

I don’t see how this is true. If anything transaction references based on the actual subject would make scamming slightly easier because a scammer can glean information from the reference.

I’m going to stop here, though. I don’t see that this is going to converge on any shared agreement.

Take care. And if you celebrate the holidays, happy holidays, too.

There is a Bitcoin seller B, a thieve T and a victim V.

T proposes to buy Bitcoin from B. T offers a new iPhone for a very low price to unsuspecting V. V agrees to buy it. B gives T account details and transaction reference so that T can transfer money to B's account. T gives these details to V. V transfers the money. B transfers Bitcoin to T. T disappears.

If only transaction reference contained information that the transfer is about buying Bitcoin, V would have never paid the money.

The scheme was quite common in UK because banks did not like Bitcoin so Bitcoin sellers and buyers avoided referencing it in bank transfers.
