The only financially correct way to avoid value fragmentation and merchant shutdown and to allow permission less evolution of rules

First. This topic has nothing to do with ideology. A rule of a blockchain may be drastically attractive/unappealing to most/some people but it is impossible to forcedly forbid the rule due to the "permission less" nature.

Second. Suppose a coin is only valid in chain 1 and chain 2, the price of the coin is the price of the coin only valid in chain 1 plus the price of the coin only valid in chain 2. If your brain cannot function in abstract way, just imagine the bitcoin network as a corporate of forges and the game is like this: Let W1, W2, W3 be the energy power of forge 1, forge 2, forge 3. The amount of gold of a coin added by a specific forge i is the notional amount of the coin times Wi. The gold is always in recycle, moved from the input coins to the output coins with the help of all forges. Every coin is a plastic box containing some gold, and the steps to add the gold is as below.

When a transaction is broadcast, for example, a transaction being input 1 and input 2 to output 1 and output 2 and input 1 coin and input 2 coin are both valid in all chains. The corporate does the following:

prepare two empty plastic boxes for output

for i from 1 to 3

If

the transaction is valid in rule of forge i

then

remove gold amount of input 1 * Wi from input 1 coin and remove gold amount of input 2 * Wi from input 2 coin

add the amount of gold output 1 * Wi into output 1 box and add the amount of gold output 2 * Wi into output 2 box

Mark "void in forge i" on the two input boxes.

else

do nothing

end if

Therefore, for example, if the transaction is only valid in chain 1 and chain 2, the output 1 box will contain gold amount output 1 * (W1 + W2), the output 2 box will contain gold amount output 2 * (W1 + W2), the input 1 box and input 2 box will have "void in forge 1 and forge 2" mark, the input 1 box and input 2 box are still valid in forge 3 but contain less gold. The price of the two output coins is W1 + W2. The price of the two input is reduced from W1 + W2 + W3 to W3. The more forges rule that a coin is valid, the higher is the price of the coin and the more stable is the price of the coin thanks to energy being always positive and conserved. If a forge rule is so devastating that no coins can be valid in all chains due to its inclusion, that forge is simply another corporate to create another coin and not part of the corporate; a user would need to craft two transactions instead of one when he conducts a deal.

Knowing that the coins in the same chain do not necessarily have the same price, people will category coins by their validity and calculate their value by market data of the very category. When chain 2 and chain 3 are in fight for some nonsense therefore mining power jumping between chain 2 and chain 3. Prices of coins valid in chain 2 and chain 3 or of coins valid in all chains remain. If forge 1 moves part of its energy power W1 helping chain 2 for the fight, then prices of coins valid in chain 1 and chain 2 and chain 3 or of coins valid in all chains remain.

The last trivial choice to everyone is that, given that the coins valid in all chains have highest price and stability, which coins will Joe chooses as default setting of the wallet as a retail customer or currency name marketing as an exchange or item price on the tag as a merchant? Exchange market and merchants can be nonstop even during the chain 2 and chain 3 fight.

Much more than that. "permission less" is not only for software innovation but also for rules evolution.

Want a CPU mining algorithm? Split a chain and enjoy the same network players and go ahead without anyone's permission. Remember bitcoin is in fact a proof-of-energy-work system. If the chain does grow to significant energy power around the globe to do the mining work believed by people, the chain will be part of "all alive chain" and a smaller hash rate is meaningless.

Want a KYC chain? Split a chain and enjoy the same network players and go ahead without anyone's permission. If it cannot grow to viable energy power around the globe to do the work believed by people, the coins only valid in this chain will be near zero price and this chain will hardly be part of "all alive chain".

All solved by market with correct concepts, no geeks, no round table, no war, all peace.

Community To-Do list

1. Exchanges and people shall adopt the financially correct definition of a currency by the coin itself rather than by the chain it sits. Update your system accordingly and don't behave financially dishonestly. If market price signal is clear, no one will mix high price coins with low price coins carelessly.

2. Wallets shall have the capability to select coins of specific choice of validity and never mix the notional amount of coins of different category for reporting balance amount. All current implement of wallets wrongly adds an apple with a banana.

3. Wallets shall provide basic coins split capability so that users can enjoy the specific feature of a specific chain if they intend.

Before the 2018 Nov split, BCH is the category of coins valid in three chains: legacy chain, ABC chain, BSV chain where the three chains happen to be identical. After the split, legacy chain is dead and all energy power of legacy chain goes into ABC chain and BSV chain. Therefore, after the split, BCH shall be still the category of coins valid in ABC chain and BSV chain for the sake of all good properties of coins valid in all alive chain.

If you are not interested in features offered by a specific chain, you don’t need to pick a side, remember you can easily split your coins anytime but never possible the opposite direction. You may have already the coins valid in all chains. If not, you can also get one from the exchange after the exchanges accomplish the task in the above To-do list. BCH, as coins valid in all chains, cease to issue new coins with 17.4M volume after Nov 15 2018 and remains the volume only if no one splits the coins. ABC, as coins only valid in ABC chain, start issuing coins up to 3.6M volume plus the volume from users’ intentional BCH coins split since Nov 15 2018; similar for BSV. The coins of “valid in all chains” will evolve. For example, if BSV chain is dead and no new chains appear down the road, ABC coin is also the coins valid in all chains, therefore becomes BCH too and ABC coins volume is merged into BCH volume, totals 21M volume.

The same method should have been adopted in 2017 chain split if people are wise. Then the bitcoin of a user who is never interested in these split events is price at sum of BTC price and BCH price.
