http://galaxies.mygamesonline.org/digitalisassets.htmlNOTE that obtaining enough miners to secure the blockchain SECURELY is INSANELY EXPENSIVE!
IT USED TO BE A BLOCKCHAIN, but blockchains are NOT SECURE unless massive hashing power, which is insanely expensive, is used to secure them. number of such blockchains existed, some seven or eight or more, but even using merged mining so all of them could all share the same hashing power and thus share the cost, it simply was not feasible, not enough miners were obtainable, to get enough miners would have required totally insanely huge costs.
Until the sheer number of transactions paying fees is huge, it simply is not economically feasible to pay enough miners to secure the chain, EVEN USING MERGED MINING!
For this reason many chains are still waiting for off the shelf, ship when ordered ASICs, so they can all gang up to create a truly massive Massively Merged Mining setup so all the many chains can all be secured using the same hashing-power, hopefully bringing the cost of such huge amounts of hashing down far enough that it will become practical to secure blockchains.
Consider how much the bitcoin blockchain costs per day to secure it!
Once ASICs start being easy and quick to get, then even though bitcoin miners have shown themselves unwilling to secure more chains using their hashing power via merged mining, any chains willing to set themselves up with the merged mining capability will be able to be secured for only a fraction of the current cost of securing a chain. The more chains, the cheaper the cost of securing each one!
Until then though, it would be insane to let attackers screw up valuable currencies by putting them out there as insecure blockchains begging to be attacked.
