I've finished writing part 1 of "OcapPub: Towards networks of consent", which is to say the "Conceptual Overview" section gitlab.com/spritely/ocappub/bl

There's a lot there already, and we haven't even gotten to Part 2, the "How to Build It" section yet. I'll begin work on that tomorrow.

What's here already is more or less an explanation of *why* OcapPub is taking the particular direction it is taking, and why other approaches run into serious problems.

@cwebber amazing work. "We will read it to our readers" I think you meant to say "leave" instead of "read".
What type of stamp do you imagine, hashcash or some type of coin ?


@cjd Oops! Nice catch, fixed.

Also I meant to say "postage" or "postage stamps". In retrospect it's fine to say "stamps" as long as you introduce them as "postage stamps" first to remove ambiguity.

As for what they are, there are a few options, and this system is compatible with a currency-like system or something like hashcash. But I have an idea for something that I think may be a weird hybrid... more on that soon. Maybe that's part three, or a second document ;)

@cjd Just as a preview:

- I don't like how hashcash implies constantly burning CPU. But we may be able to "reuse" that.
- I don't trust blockchain style cryptocurrencies. Digicash and other fiat-issued systems are more okay, but I'm not wildly enthusiastic of making this too money-like in the first place, though there's no reason someone couldn't use real money.

I've only run my idea by one person, I need to run it by a few more before I'm brave enough to publish it. Wanna volunteer?

@cwebber @cjd I'll read it, but I'm still fairly junior at developing distributed systems

@cwebber if you're interested in fielding ideas, I'll definitely give it a read.

FWIW I've been working on a proof of work for a project of mine which requires miners to collect as many hashcash'd messages as possible, thus creating a "bandwidth hardness" of the algorithm and also turning the mining pools into a decentralized pubsub system.

My intuition is that too get adoption in the fedeverse, whatever the system, stamps will need to be an optional extension.

@cwebber Problematically, with "stamps", if Bob has the ability to return the stamp to Alice because her message was not spam, then stamps can be exchanged so financial markets can emerge, and financial markets are at the heart of the crypto/blockchain FOMO esthetic.

However interesting this thinking is, my cynical side suspects that the fedeverse will stumble over a handful of bad ideas before converging on a system of gossiped whitelists, so like BGP, you need at least 1 node to sign for you.

@cwebber A really cool model (IMO) would be if everyone allowed a certain number of stamps for servers who they explicitly choose to federate with. When a message is viewed and not flagged, the stamp is returned to the author. A new server might get only 50 stamps plus 5 per day with an upper limit of 500. Getting old and controlling spam well leads to increased limits.

But alas, oceans don't boil easily...

@cwebber @cjd It'd be neat to use GNU Taler for this, though that requires banks to actually support it...

@jfred @cjd Does it? Or does it only require so if you're trying to link it to real money? What if we're not? :)

You can issue Taler like a fiat currency, yeah? Their demo even has something they issued that way, just for demonstration.

@jfred @cwebber
Any time one proposes a currency-like thing, people immediately (and rightly) ask "why did you say that? what's in it for you?" which makes it all but impossible to bolt it on to an existing project.

I suspect the most likely thing to work is a challenge/response hashcash where message recipients can decide what the work actually is... "here's a challenge, download this webassembly file, execute it with the challenge and give me the result".

@cjd @jfred The thing I'm proposing though isn't currency-like-enough, as hopefully people will see. For one thing, "postage" expires... not a desirable property in a currency.

@jfred @cwebber
Then some instances can make spammers fold proteans, others can make participate in SETI (is that still a thing?) others can make them mine monero...

@jfred @cwebber
Another advantage of just throwing people a challenge and a wasm file to compute the response is that you can make the response also contain the message you want to send, so then you have protocol-agile asymmetrical encryption capability builtin
