One vanity address among eleven plain ones

The split

Why one and not twelve

If a readable prefix were valuable, a market would grind one for every address it published. Nothing stops them. The work is per address and the cost is the same each time, so twelve vanity addresses would cost twelve times what one costs, which for a six character prefix is an affordable bill rather than an impossible one.

That they did not is the more informative fact. It suggests the prefix was treated as decoration on one address rather than as a property the set was supposed to have. Eleven strings were taken as they came.

It also means any reader using the readable prefix as a test would reject eleven twelfths of the published set. That is worth sitting with. The test people most commonly apply to an onion address, which is whether it looks like the name it claims to be, fails almost every address here, and the addresses it fails are not fakes.

What the vanity address does not establish

It does not establish that the address is official, current or safe. Grinding for six characters is a job anyone can run, and somebody producing a lookalike would grind for the same six, because those are the characters people check. Two addresses can both open with the market name and be entirely unrelated.

The reason this is worth stating flatly is that vanity prefixes are the single most effective way of borrowing credibility in this space. A string that spells the name reads as endorsed. Nothing endorsed it. A machine ran until the output looked right.

The detail of what those six characters cost, and why twelve chosen characters is not merely expensive but out of reach, is on the page about grinding cost. The record for the vanity string itself is at its own page.

How this site treats the split

As a fact about characters and nothing more. The vanity address appears in the list in its published position, with no marker, no badge and no note suggesting it is preferable. Its record page reports that it opens with the name in the same row that reports how many digits it carries, because both are the same kind of fact.

Questions

Is the address that spells the name the official one?

This site cannot establish that and does not claim it. A readable prefix is the output of grinding, which anybody can do. It carries no information about who published the address.

Why do eleven addresses not spell anything?

Because grinding is optional and costs separately for each address. Taking eleven keys as they came is the normal and cheaper choice.
