It seems like the similarity between Spaces and DNN ends at 'both use bitcoin' (more specifically, both use bitcoin txid, but even there it differs).

Based on my understanding, at least on a surface level, Spaces has scarce names, must go through a bidding process to get a new name, and that process results in burning bitcoin (at scale, this isn't healthy for bitcoin in my opinion), and said process might result in requiring the user to pay (burn) a high number to get a single desired name/id/domain.

##Spaces:

Pros:

-uses bitcoin

-name transfer

-decentralized website

-equal to dns human readability

Cons:

-burning bitcoin

-relies on 'op_return' (putting spam in bitcoin, and spam here means anything that is not transaction data)

-similar bad ux as dns in terms of acquiring a name (or worse? requires consensus permission? i might be wrong on that 'requires consensus permission' bit)

-potentially very expensive

-scarce names (might not be a pro depending on who you ask, but for the end average user, and for scalability, it's a con)

-(not technical con:) brand tied (.spaces, .bitcoin)

Neutral:

-Can be updated to do what DNN is doing to circumvent IANA/IPs

##On DNN's side:

Pros:

-uses bitcoin

-decentralized websites (infinite)

-cheap

-doesn't burn bitcoin (but circulates it in a neutral sense)

-doesn't put any data on bitcoin (zero / no spam) / no reliance on 'op_return' or anything else, just the txid self-transfer

-no permission

-easy UX (self transfer btc, one click publishing of nostr events (4 button clicks at the moment, but will make it a one-click process soon), and done. Two actions. Well, three assuming you don't have funds on your bitcoin derived nostr address)

-no name scarcity (have whatever name you want, the ID/TLD part is a 'you get what you get')

-Brand-agnostic ('nabceabsurd' is just a simple structure)

Neutral:

-human-readable and memorable, but not as equal to the level of dns.

Cons:

-no transfer (though in most cases, 99%, there isn't a need to do it)

Aside from that, I think I'd have a much easier time with adoption, and faster, from developer adoption on nostr and on bitcoin (it's infra is bitcoin+nostr, and bitcoin and nostr sides are merging more and more over time, as well as how easy it is/would-be to implement dnn support on existing nostr signers apps or extensions), to user adoption through short to long term strategies. There's also an assumption of Tollgate's future potential growth/success that utilizes nostr, so DNN's growth path is intertwined with Tollgate as well.

So far, I see Spaces as a market of names to have fun in (and with usefulness in terms of identification and/or rendering sites), but not as the non-hostile slow/invisible infrastructure takeover of ICANN-DNS&IANA which DNN is going for. Though that's my opinion so far from what I looked into, and of course you're asking me who is the person behind DNN in this 'DNN vs Spaces' comparison x3 but who knows, maybe Space will be the dominant network in the future (hopefully no though, not out of malice but out of those cons i mentioned) and DNN won't be, which is fine, but I'd want to continue developing and pushing DNN to be that 'new internet' (hopefully along with Tollgate, it's awesome =3) as I took decisions for it to be simple, easy, infinitely scalable within bounds, cheap, not worry about names, and bring in a host of secondary benefit solutions.
