If it's\ntoo big, as Tamas showed, perhaps a hash of it, and for coins without a\nmagic number, a hash of their name (or some unique identifier).\n\nThat being said, I agree with Andreas that something that is 90%\ninter-operable seems very dangerous and will give people false expectations\nwhen they miss the corner cases.  If the structure isn't going to be shared\ncompletely and have all support shared, having it completely incompatible\nalong with a mechanism for converting part of it to another wallet seems\nsuperior.  The worst types of losses will occur when someone tests out\nsomething with a limited use case, sees that it appears to work, makes\ndangerous assumptions, then gets burned when it's too late.\n\n-Allen\n\n\nOn Thu, Mar 27, 2014 at 11:06 AM, Pavol Rusnak \u003cstick at gk2.sk\u003e wrote:\n\n\u003e On 03/27/2014 04:57 PM, Allen Piscitello wrote:\n\u003e \u003e Don't most of these coins have a magic number already assigned that is\n\u003e \u003e unique?
