What about multiple blockchains? And i dont mean competing blockchains, i mean other bitcoin blockchains that use the same bitcoins we use now. These blockchains wouldn't add any coins to the economy and would work entirely on transaction fees. Coins would be added to these blockchains by sending coins from the original blockchain to an address on the new blockchain and coins could be sent back to the original blockchain at any time.
The reason i suggest this is because eventually if bitcoin became a global phenomena, even while pushing the upper bounds of blocksize that the network could handle it could still be the case that transaction fees could be in the range of hundreds or thousands of dollars to get 1 tx included in a block. I dont really know what the solution to this is and admittedly i am grasping at straws here but who knows maybe you guys can take the idea and run with it.
Unless there where reasons to fafour inner blockchain transactions more than others, this would on average increase the total size by ~50% for the same amount of transactions.
25% Chain A to Chain A transactions
25% Chain A to Chain B transactions
25% Chain B to Chain A transactions
25% Chain B to Chain B transactions
So 50% of all Transactions would have to be noted in two chains.
Unless I understand this proposal wrong.
hell i dont even really understand the proposal. its just process of elimination that leads me to this proposal (since everyone elses proposals have serious problems). But i imagine that blockchains would be regional. Since most trades would be with people in your area than most transactions would remain on the same blockchain. You are right though that if you wanted to send coins to someone on another blockchain you would need to pay 2 tx fees. Which would mean inorder to have the total fees cut in half we would need to ~ quad-ripple the total number of chains not double it.
this would also create a market for firms to store up large amounts of coins from each blockchain and make big transactions instead of a lot of little ones. This would really encourage people to use services like bitpay rather than sending the coins directly.
