This is the twenty third question / topic of the 30 days writing challenge I announced a couple of days ago. The total amount in prizes is 90,000 SNAX and it's being distributed as 3 daily prices of 1,000 SNAX each. For all the details, please check this post.

Well, @chrisaiki proposed a day ago a p2p exchange on Steemit, here is his initial proposal: https://steemit.com/snax/@chrisaiki/proposal-for-a-p2p-steem-snax-exchange. The topic today wants to build on top of that and find ideas, approaches and techniques for actually making this happen.

Basically, the p2p exchange will work as follows:

• seller posts an offer for accepting SNAX for STEEM (or the other way around)
• buyer fills the offer by sending the first pair (SNAX or STEEM)
• seller close the order by sending back to the buyer the second pair (STEEM or SNAX)

I do think this can be implemented just using Steemit as an offer board, initially, but as we go along we will need more fine grained control over what happens. Here are my initial thoughts on this, feel free to contribute in your own articles.

• formalize the offer posting, using a stripped down "mark-up", ex: |||offer-type||| (sell/buy), |||offer-pair|||, |||offer-validity|||, |||offer-amount|||
• setting up a node just for parsing the offers would be costly (and centralized) so I would go with a browser extension that will scrap the blockchain for the last 2-4 days offers, any offer that is not there will be excluded, hence the seller would need to repost it, just to keep it fresh
• the exchange should come up with some sort of memo exchanged and verifiable (both STEEM and SNAX have this capability, so it will be relatively easy to implement)
• as offers are gathered, a depth chart could be created, adding some nice UI to the exchange - this UI could also include the latest filled offers, etc

Any other ideas? Maybe access to coding resources? Or putting up some hours into it if you already know how to code?

Also, an important part would be promotion of this p2p exchange, so the articles that would spread the word more about this approach will get a higher score from my part.

IMPORTANT: please state your SNAX username in the post, so I know to which account to send the prize, should you be amongst the lucky winners! Thank you!

Wanna know when you're getting paid?

	I know the feeling. That's why I created steem.supply, an easy to use and accurate tool for calculating your Steemit rewards

It's free to use, but if you think this is a useful addition, I'd appreciate your witness vote.

Thank you!
