| Thanks. This is a helpful link. If the majority of good/honest nodes and the Bitcoin developers decide to implement a change, presumably this change will occur. My understanding is this happened recently with Taproot for example so one must infer that this is possible. Obviously such changes only impact new blocks but naturally this can still have an impact on the general ecosystem. Here is a hypothetical situation for consideration (please shoot holes in it!). The year is 2105, Bitcoin is the defacto world currency. Everyone is paid in Bitcoin and all transactions are performed in Bitcoin. Democratically elected world governments control the majority hashrate since they have decided that it is too risky to allow private individuals to control the network. A major financial crisis emerges in which prices of goods relative to Bitcoin are on a severe downward trend. Individuals realize that if they simply delay purchases, their own purchasing power will increase - further reducing demand for goods and services thus further decreasing price. Since businesses cannot make a profit in this situation, workers need to be paid less continuing the deflationary cycle. Democratically elected world governments decide that inflation is necessary in Bitcoin in order to avoid an exceedingly long painful and unnecessary economic depression. World governments work with Bitcoin developers to start rewarding miners with 20 Bitcoin per block mined thus devaluing the currency. 99.9999% of citizens of the world agree with this move. After the financial crisis is abated, world governments determine that a 2% inflation rate should be built into the Bitcoin in order to avoid such problems in the future and virtually everyone is happy with this. Is such a scenario impossible? |
So unless all the world governments decide to make it illegal to mine the old chain, it wouldn't work.
