This is great that we have multiple implementations for the mastercoin protocol, but they should all agree with each other.
I think the sync action between the different implementations deserves its own thread.

Currently I compare:

• https://masterchain.info/mastercoin_verify/addresses/0
• http://mastercoin-explorer.com/mastercoin_verify/addresses

and generate a diff using:
https://github.com/grazcoin/mastercoin-tools/commit/0fe108a0e234441d533414efc6ef4e7e4d1ac90d

The diff is generated every round hour (since it seems like a heavy task on mastercoin-explorer.com):
https://masterchain.info/general/difference.json

Let's discuss the differences and try to get a sync.

That's how the diff looks now:

I'll just start with few:

on mastercoin-explorer a smaller amount was calculated (multiplication of amount times the price). rounding error.

Let's try to make this list shorter until it vanishes, and then keep it empty.

We have been having a discussion in the development thread about these payments. We want to accept them.


I'm currently reparsing all exchange messages because of the added rule that only tests are accepted for now. Will get back on that one :)

Here is the difference between mymastercoins mm and masterchain mc.  I'll look at each address trans and report back.

For transaction

725210a6bfea06e4aa9a582602d758db920eff9c720aca380d6e77c08a4108ac

The reference address is 18jArgoK7EPRaozSN6Eprtnjb1LMQQ3McF

The largest output is the change address which is also 18jArgoK7EPRaozSN6Eprtnjb1LMQQ3McF

1NK1rJSkMeDtg5SXfXaSbD14QxAqQbqAr6 - (Unspent) 0.00006 BTC

1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P - (Unspent) 0.00006 BTC

Is this transaction valid?

(For my implementation I disregarded output addresses that are the same as the Reference address. Then used "peek and decode". )
