We have a direct solution to the bitcoin block size dilemma

Define the BTC as a coin which can interchangeably be applied to a class of block chain formats. So, use the big block for large trades, break it up with short blocks, and let the ledger service queues be priced. We get the class BTC, usable in four or five tokenization schemes, switched via priced queuing. Should be legal under sandbox rules.  But the scheme  only makes everyone more efficient because the sandbox separates token and coin.  The new technology from bitcoiners becomes available to coiners.
