Bitcoin : An outsiders view: ABC vs SV
With the 15th being around the corner, and my reddit feed full of ABC vs SV I thought I’d give my perspective. I’m an Eth developer but generally interested in all sorts of chains and technology, and hold some BCH.
Part of what I think makes BCH (and to some extent BTC) unique in the current space is that they aim to do one thing very well. With a non-turing complete scripting language it’s possible to focus on just the characteristics of sound money, and do that without being distracted.
AFAICT, ignoring the individuals, on the tech side, the debate really falls to:
– ABC: OP_DSV – add opcode to allow more complex scripts, CTOR – transaction ordering .
– SV: 128Mb blocks, some future talk of more radical changes (i.e. reverting provably burned coins)
In my mind OP_DSV is not particularly necessary for sound money. It does add some additional capabilities but I’m not convinced that BCH needs them, or should be trying to extend in this way, rather than e.g. looking at privacy related functionality which is related to the fungibility of money. From what I can see CTOR seems less controversial, and probably makes sense as an optimisation which doesn’t really impact the fundamentals of the protocol I think.
As such, it seems to me that *technically* both forks are reasonable. I don’t think it’s true that just because CSW may be able to muster hash power & social media influence to “force” this fork, he would be able to do the same in the future for a different (possibly technically more contentious) change like re-issuing provably burnt coins. Not adding OP_DSV now doesn’t necessarily preclude doing it in the future, possibly when if / when it is less contentious.
In terms of decentralisation, hash power and bad actors, I think there are def. lessons to be learnt – blockchain governance remains a total work in progress and I guess hard lessons have been learnt (e.g. ETC vs ETH) and will continue to be learnt. The centralisation of mining power is def. a huge problem for the sector IMO across most chains and something we should all be looking to innovative solutions (I like Casper, but ProgPOW or other ASIC resistant options are all options).
I hope that, whatever happens tomorrow, the BCH community finds a way to continue to coalesce around the ideal of a decentralised cash protocol.
Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority.
