Recently, we have seen Bitcoin forks, in the form of Bitcoin Cash (BCH) and Bitcoin Gold (BTG). They are a messy and chaotic way in which Bitcoin is trying to deal with its low transaction capacity, or low block size. It is unsettling and suggests Bitcoin possesses a certain instability.
Both Nu and B&C Exchange do not have the vulnerability to forks that Bitcoin has. Why? In the case of Nu, it has currency liabilities. Right now, these liabilities total about 25% of the NuShare market cap. Imagine a fork of the Nu blockchain along the lines of what Bitcoin Cash did with Bitcoin. The question emerges: will the new fork include Nu’s currency liabilities?
If the architects of the fork answer no, then they are nothing like Nu without Nu’s currencies. This is what Augeas chose to do, which has gone nowhere, and appears to have no market value. Furthermore, a fork of Nu that doesn’t duplicate Nu’s currency liabilities cannot have share buybacks fueled by currency sales as Nu does. It would be radically different from Nu, and we could expect it to be quite unlikely to overtake Nu, because it would not even be in the same line of business: stable currency.
Now imagine a Nu fork does decide to duplicate Nu’s currency liabilities. Bitcoin Cash started with about 10% of Bitcoin’s value, and is currently worth about 15% of Bitcoin. Where NuShares are backing for NuBits, a Nu fork with lower value would be ill equipped to back NuBits. Being ill equipped to back NuBits means they are especially likely to see a quick sale of a very large proportion of NuBits, perhaps even a majority. They would need to attempt to keep the peg with large and sudden sales of NuShares on their fork, which would reduce their market cap even more. This would reduce confidence in their peg, or break it, which would cause more NuBit sales on the fork, destroying their market cap and credibility. The architecture of Nu provides exceptional protection from forks like Bitcoin has seen with Bitcoin Cash and Bitcoin Gold. The economic realities of forking a blockchain with stable currency liabilities are very bad for the challenging fork.
Also, consider Nu’s tier 4 reserves, which currently consist of Bitcoin, Bitcoin Cash, Ether and BlockShares worth about 1.2 million USD, or about 130% of Nu’s currency liabilities. The fork can’t duplicate these reserves. The fork will have exactly $0 in tier 4 reserves to start.
Consider what this looks like for NuBit holders. You pay $1 for a NuBit on the main chain. When a fork occurs that duplicates NuBit liabilities, you now have a pegged currency on two chains: $2 if they keep the peg on the fork. A very good deal indeed. You will probably sell your NuBit on the fork because of the high probability the peg will be lost on the fork. Even if the peg breaks and you can only sell your forked NuBit for $0.50, you are still a very happy NuBit customer: you got a large profit from your stable currency purchase: an unexpected windfall profit. This makes buying NuBits more attractive to you, not less attractive. So you buy more NuBits, hoping for another fork.
Now let’s turn our attention to what a fork of B&C Exchange would look like once it is operational. Recall that the blockchain is associated with multisig deposits of other native blockchain assets: Bitcoin, Ethereum, Litecoin, Dash, etc. These multisig deposits cannot be included or duplicated in the fork. The B&C Exchange BlockShares can be forked and duplicated, but the exchange deposits of Bitcoin, Ethereum, Litecoin and so forth cannot be forked and duplicated with it. So, you have a decentralized exchange with zero deposits and zero volume. The value of B&C Exchange will lie in its deposits and trading volume, so you have no or little value in the fork. It is very unlikely to succeed or threaten B&C Exchange.
We can see that both Nu and B&C Exchange have exceptional resistance to being forked like Bitcoin has been forked in the form of Bitcoin Cash. In the case of Nu, the currency liabilities make it unprofitable to fork. In the case of B&C Exchange, a fork can’t duplicate the exchange deposits and trading volume.
