The First Micropayments Marketplace

Neat. What exactly is the technical limitation requiring the 21c computer as opposed to, say, a raspberry pi with the 21c library. I know there is the mining chip but what else? What happens even you do a "21 flush"?

1) You can sign up for a free client at 21.co/free. When released, that'll give a lot of the functionality on most devices.

2) What a Bitcoin Computer provides is (a) a ready source of bitcoin, (b) a set of ports to plug in sensors and actuators, and (c) a small personal server with a reasonably large amount of disk space (128 GB). As you will see in subsequent blog posts, that combination of features allows you to have something on your desk that can buy and sell API calls into the marketplace, potentially making money for you in the background.

You can think of this as a generalization of bitcoin mining. Rather than sending hashes up to the network and getting bitcoin down, you can send other kinds of compute up to the network and get bitcoin down in return.

As a simple example, we'll be releasing code which will allow others to rent your device along with a fleet of others to do distributed uptime/latency checking (like Pingdom) or to do distributed performance testing (like Blazemeter). The "distributed" aspect here is important because you can only go so far in simulating real traffic from the confines of rented computers in a datacenter. The more realistic the test, the better.

So: basically, Bitcoin Computers are easy-to-rent grid computers that can buy and sell services to the grid in return for bitcoin. More here: https://21.co/learn/grid-computing-with-bitcoin-micropayments/#next-steps

You guys are pushing things forward. Please keep up the amazing momentum.

Very excited to see what you are doing here. Some suggestions for your web page:

a) On your web site when I click "buy" it takes me to a buy page but the headers all disappear so there are no links to click at the top any more. b) On your web site when I click "marketplace" there's a big search box at the top that masks all the headers. Doesn't look good. Would be better to have that in the body of the page so I can still see the header. The three navigation bars as a way to make the search disappear were not obvious to me. c) I think your company has a blog or news page but can't find how to get that. Would be nice to have a link for that at the top. d) How about a link to the URL that shows fees. Can't see how to get to that URL from your main site and can't remember the URL.

Looking forward to seeing the blog / news link so I can follow what's happening.

Some suggestions for your company:

Frequent news announcements are really good. Better to have smaller announcements more often than big ones :-)

As long as you don't own a metal desk and like paying a 5x margin on an sdcard and crap miner.

Do you run an alt-coin site? Well prepare as 21 sold so far miners DDoS you!

Hey, thanks for your great reply. I think the part I'm a bit confused if what exactly differentiates the free client from the one on the 21c computer. Is it just that the non free client is configured to use the mining chip?

"a ready source of Bitcoin"

What are the average numbers on that? $0.10 a day? Less?

To fund any economically significant activity the choice seems to be either buy a few dollars of Bitcoin, or leave this thing running at a loss for a third of a year or so.

Do you have any actual use cases where loss making in-device mining is the most efficient and elegant way to give an internet connected device access to Bitcoin transactional functionality?

There is no such limitation. In my view, the name ' "21" marketplace ' betrays an attempt to force the association.

Otherwise, I think it would have been named "Bitcoin Rent-a-Comp" or something.

Ho. Ly. Shit.

That's cool

[–]frankenmint [スコア非表示]  (0子コメント)

Some of the endpoints you can pull include things such as: Zip Code lookup data, social media ranking analysis, Sentence analysis....all for sale at a fixed rate per api request. These are definitely baby steps, but they show how we could build out more complex services over time it seems.

Wait but people said micropayments are impossible with Bitcoin /s

[–]dj50tonhamster 6ポイント7ポイント  (5子コメント)

I know that's sarcasm, but to be fair, 21 does default to its own form of off-chain transactions that make micropayments feasible. You have to explicitly ask the computer to do on-chain transactions if that's what you insist on.

Hi there - we do support payment channels now, actually! See here:

https://medium.com/@21/true-micropayments-with-bitcoin-e64fec23ffd8

And here is an example of using it with a marketplace URL:

Ahhh, I had forgotten about that. Thanks.

[–]Boltrosianredditor for 12 days 2ポイント3ポイント  (2子コメント)

So are those default micropayments on 21's own closed system Coinbase/ChangeTip style?

[–]brg444 4ポイント5ポイント  (0子コメント)

They have their own implementation of payment channels right now AFAIK.

[–]dj50tonhamster 2ポイント3ポイント  (0子コメント)

Yeah. They have their own little setup amongst 21 computers (and, once it's out, any program using the 21 API). It may switch over to Lightning or something else down the road. We'll see.

This is a marketplace allowing anyone to purchase computational services for Bitcoin micropayments. This is basically a marketplace for machine payable APIs. The APIs offered here will provide some computational service in return for Bitcoin. This incentivizes people to provide easily-accessible APIs that require no sign up or authentication.

[–]Kristkind 0ポイント1ポイント  (0子コメント)

Yes.
