'The whole point of hashing to a blockchain is to benefit from its greater security, so we have to use the most secure one available. Bitcoins dominance might not last forever, though, due to scalability issues with the protocol. Its blockchain is too large, transaction speeds are too slow, and the fees are too high to be used for anything except currency.
The ultimate blockchain will be one designed entirely for this purpose, a relatively small file intended only to store hash values. Its low resource consumption will make it easy for any device to join the network, and conceivably, almost every device will. It will become the universal judge of truth, capable of resolving any disputethe blockchain of blockchains.'
Can Viacoin aim for this position, being the blockchain of Blockchains?
