hi xchrix! Thanks for the interest.
There is already a related feature implemented.
maybe it is good enough for you.

web interface:
https://masterchain.info/Currencies.html you get the overview of volume, last price (with links to last trades of that currency), etc.
https://masterchain.info/index.html?filter=accept&currency=GRZ - the last deals of GRZ coin.

json:
https://masterchain.info/general/GRZ_accept_0001.json - the last 10 deal accepts of GRZ coin.
https://masterchain.info/general/MSC_accept_0002.json - the previous last 10 deal accepts of MSC coin.
https://masterchain.info/general/GRZ_sell_0001.json - the previous last 10 sell orders of GRZ coin.
https://masterchain.info/general/extracted_currencies.json - the automatically extracted currencies list (with their names, their exodus address, the amount minted, their internal currency list, which is now real and test coin only, and more).
https://masterchain.info/currencies.json - currencies, last price, number of transaction history pages, number of sell transaction history pages, number of accept transaction history pages, exodus address.


obviously these API exist for each generated currency.

If you need some different data on the api - just ask, and I'll see what it takes to implement it.

Congrats Graz!

I've been using the masterchain.info wallet to do simple sends and I'm happy with the results.

I'm confused about these new currencies though.  Are they implemented as master protocol user-currencies or
something else?   I have no idea what a meta-chain or a nested chain is.

Also, do you have any plans to support trading of MaidSafe coins now that the crowdsale has finished?

Thanks!

The new currencies  are mastercoin protocol based, but the exodus address (and the control of the whole chain) is given to the user that issues the coin, and therefore they are not connected to MSC. These are not the user currencies from the Mastercoin spec.
On each such chain (MSC, GRZ, etc) internal user currencies (as mentioned in the mastercoin spec), as well as any other mastercoin spec feature could be added.

The original MSC is the first "mastercoin protocol based" coin, using the exodus 1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P
Any other coin on masterchain, e.g. GRZ uses the same protocol and the same parsing stack, but it has its own unique address - for GRZ it is 1GRazCon4gDqTh1pMNyh1xHVWnbQEVPfW8

As for MediaSafe coins - I don't plan to add them to masterchain.info in the near future, as I am too busy with the development of the multi-exodus feature. This does not influence the MSC balance which should be in consensus with other MSC implementations.

this data is good but its missing one info. the timestamp of the trade. are you able to provide this? otherwise i have to check the blockchain for each transaction and get the time. very complicated

Congratulations Graz. Well done.

All the best on your coin, as well. There's innovation in employment with GRZcoin!

The timestamp of each tx is is already provided inside the json in the field "tx_time".
E.g. for https://masterchain.info/general/GRZ_accept_0001.json the timestamp of the last tx:
"tx_time": "1398345496000" which is 24 Apr 15:18 (my time zone).

The consensus checker of MSC with the other implementations (masterchest and mymastercoins) is alive on:
https://masterchain.info/general/MSC-difference.txt

currently the differences are:

It seems that at on each consensus issue, there is at least one other implementation that agrees with masterchain.
As masterchain uses mastercoin-tools which is the official/reference implementation - the other implementations has to align accordingly.

update: consensus issues solved.
MSC foundation decided to modify history:

transaction got re-validated now:

I just came back from bitcoin2014 an Amsterdam and I have seen that a new coin got minted on the distributed exchange.
XXX coin/chain.
It is available under xxx.masterchain.info

The minting transaction was:
https://blockchain.info/tx/c4397e470c059dd9a2a87a63959a009338a1c59d8aea3b774df3ebf4251cefc9

The main chain address:
https://masterchain.info/Address.html?addr=1xxx1Wt8o8sv4JNdZXL8hTEZdXMTcDUa1&currency=XXX
contains 5002.24330009 XXX coins and 5002.24330009 Test XXX coins.

The details of the chain are available on the currencies page: https://masterchain.info/Currencies.html

No specific rules were published for this chain (at least google says nothing about 1xxx1Wt8o8sv4JNdZXL8hTEZdXMTcDUa1), and no sell offers are available, but the distributed exchange supports already the XXX coins.

@ XXX chain owner:
Congratulations !
I suggest that you send some portion of the coins to another address where you maintain sell orders.
The chain private key must be kept more secure than all other private keys
It would have been best if you keep the chain private key totally offline.
For this you could use the offline signing feature on:
https://masterchain.info/offlinesign.html

@ XXX chain owner:

I have seen few transaction created by you which didn't get confirmed on:
https://blockchain.info/address/1xxx1Wt8o8sv4JNdZXL8hTEZdXMTcDUa1

The reason is too small fee ( 0.000001 BTC)
https://blockchain.info/tx/1874eed879a2da857f7cfd9c3145f3673c3a497f2d7fabc9b176a6f7fe42b44d

You can either try to double spend the same outputs, or just wait and hope that this transaction will get confirmed.

Since all the following transaction which depend on that one have a reasonable fee (0.0001 BTC), there is a chance that they will all get included in one block, but this depends on the ordering algorithm that the miner uses.

I guess this damn thing didn't work at all?  Right Graz?  Are you still working on Mastercoin now?  Going out on your own doesn't seem to be producing much.
