> This is membership protocol powered by nft. People can buy a nft and then for authorization, service provider can check whether the wallet has the nft and is valid. This way, nobody controls your membership and you can move them around the web as you like.

Who is the boogey-man trying to control your site memberships? The site operator? I highly doubt this system is robust against site operators trying to "moderate" you, but supppse it was, why would they sign up for it?

For an ecosystem originally built on keen insights on how to mix tech with incentive structures, web3 seems to have thrown that all out the window and replaced it with wishful thinking.

People use centralized platforms like patreon for memberships. They can kick you off and you will lose all your subscribers. Your patrons will lose access as well. That is what unlock tries to solve.

The membership data is stored on the blockchain publicly which everyone has equal access to. You can prove you own a particular nft stored on the blockchain by signing using your private key. So even if all data is public, authorization is secure and reliable.

So its a really fancy way to make an immutable public back up?

I mean i guess, but you could also just back up your subscribers list.

[_3jh0]

Here's the thing though.

Let's say, I want to provide special benefit to people who own membership on hackernews.

In the model where this data is public, I can query the wallet of people to check for HN nft and provide special discount or perks.

If this membership data was privately backed up, I cannot do that.

It fits nicely into the blockchain model, imo.

Subscriber owns the membership and can prove to the service provider.

Service provider has access to the membership and can check the validity.

How will you provide your "perks" if either you or your members have been kicked off the platform where those perks made sense in the first place?

With this use-case you're describing - all you have is a list of wallets that were at some point relevant to you in some way. This is the equivalent of maintaining a mailing list. Why does any of this require a distributed ledger? What problem does this solve exactly?

> "Subscriber owns the membership and can prove to the service provider. Service provider has access to the membership and can check the validity."

How is this any different than signing up with an email-address as a username?

[_3jh0]

I think you are misunderstanding something above.

I'm not the one providing HN membership. That would be YC but I as a third party can verify whether someone has a valid HN membership and provide them perks based on their membership. That is the problem a distributed ledger solves. The data is public and usable by any service provider.

To verify you have a HN account (membership) today, a service provider need to build something like keybase. That is complicated and will be different for each service.

That is the problem unlock-protocol "solves". It defines the protocol for managing these memberships. To create, verify, deploy, etc.

You need some way to pay for membership without a middleman. This is solved by cryptocurrency part of the blockchain these nfts are stored on.

Memberships are also more complicated than a list of email addresses. They can be transferred, expired, and change depending on the action of the user. For example, some provider want their memberships to be reduced to half when transferred.

This is the part smart contracts solve.

What's wrong with plain old digital signatures in this contrived scenario. If for some reason this was desired, hn signs an assertion that so and so is a member. Person presents this assertion as neccesary. No blockchain required.

Memorizing hn's public key is no more hard than memorizing what their nft is.

I suppose you'll say transfering memberships. If hn is onboard with the transfer they could just issue a new signed assertion. So the only use case is if you want to transfer ownership against the service provider's will. But how does blockchain solve that? Unless i missed some great advance in zkp, all transfers are public on the blockchain, and service providers can trace the transfers and not recognize transfers they don't like.

> They can be transferred, expired, and change depending on the action of the user. For example, some provider want their memberships to be reduced to half when transferred.

What's a real world example of someone wanting something like this? I can't think of any.

No, they need at-best a small subset of what OAuth offers. OAuth is already distributed in that sense. It's a standard protocol which accounts for this exact scenario. This is a solved problem today.

It's not different than "login with Google"/"login with Apple".

> "You need some way to pay for membership without a middleman. This is solved by cryptocurrency part of the blockchain these nfts are stored on."

What does this sentence even mean? Your membership costs are on a per-service basis, and they are tied to each service you want to pay for. Different services have different costs.

This could make some sense if services wanted to get paid with Bitcoin, but ironically enough - the Bitcoin must be converted to USD at some point down the chain?

> "Memberships are also more complicated than a list of email addresses. They can be transferred, expired, and change depending on the action of the user."

Sure, but wtf does the blockchain have anything to do with this? You're free to have an account with any service and manage it as you wish on an individual per-service basis.

It's the problem delegated auth (OAuth, etc.) already solved.

But... it's not, because a system that relies on a distributed network of middlemen isn't “without a middleman”.

> Memberships are also more complicated than a list of email addresses. They can be transferred, expired, and change depending on the action of the user. For example, some provider want their memberships to be reduced to half when transferred.

Smart contracts just add complication; this is trivially solved internally in centralized membership systems.

[fragmede]

Well, you don't need to sign up for yet another service for one. People don't want to have yet another email and password to remember. That's what OAuth and all that machinery was invented to solve.

AuthN is one of the few use cases where having a public shared database/blockchain and users authenticate using their private keys works out better in some respects because the alternative is to depend on a centralized user database owned by a private company (eg Facebook). What happens on all of the sites you used Facebook login on, if your Facebook account gets suspended?

[sdenton4]

So we sacrifice member privacy for the sake of spam? Who would want this other than the spammer?

What is forcing Patreon or any other company to allow you to export your subscriber list? And do you have a right to export even if your account has (wrongly?) been banned. Unless there's some kind of regulation involved, this is the kind of thing that easily could cease to work as expected once a company has enough market share.
