I dont quite follow/grok this offer mechanism
am I biding for nushare that then some how (my priv key of something) allows me control of my blockshares
Yes, your understanding is correct. Right now there is no B&C Exchange blockchain, and no BlockShares exist. NuShares do exist, however. You are bidding for NuShares. The proceeds from the auction will be used to create the protocol and user interface for B&C Exchange. When that is complete, the B&C Exchange blockchain will be created as a fork of the NuShare/NuBit blockchain. At the moment the B&C Exchange blockchain is created it will have the exact same shareholders as the NuShare/NuBit blockchain. The B&C Exchange client will allow you to select your NuShare wallet and convert it to a BlockShare wallet.
So, you bid for NuShares in the most immediate sense, but you will also receive an equivalent number of BlockShares if you keep your NuShares until the fork.
I realize most would prefer just receiving BlockShares, but doing this presents a number of problems. We could just sell the promise of receiving BlockShares months in the future when development is complete. This requires more trust than any other alternative and it makes your position completely illiquid until development is complete. We could create BlockShares on a brand new Peershare blockchain that doesn't yet have any of the features of B&C Exchange and immediately transfer those to successful auction bidders. This keeps your position liquid but it makes development more risky and expensive, because it would require updating a production blockchain protecting value with major protocol changes. Also, owning BlockShares will not be a passive investment. It requires that shareholders choosing to mint blocks constantly update their votes or subscribe to the data feed of someone they choose to trust to dynamically configure their vote. There is a risk that new shareholders who have never owned NuShares won't take care to configure their vote either manually or automatically. However, more than 90% of NuShare blocks have their vote actively configured. So, bringing in established NuShare holders ensures that the majority of minters will proactively configure their vote to adapt the network to changing conditions, which is absolutely essential for the success of B&C Exchange.
if I bid for a block share and I out bid some one we can still both get the blockshare if the person who I outbidded outbidded another person and there were blockshares left.....
so some people could massively pay more than others for blockshares....
is this right?
The price you pay is the price you bid.
