The full archival nodes of Ethereum and Solana are much larger than that but Bitcoin needs the complete transaction history for it to work and those coins don't.
With a modest amount of coding one could make it so that nodes would just download a UTXO set committed to by miners... it would almost just be a weekend project coding wise... of course, this would just blindly trust them for the integrity of the history but that's what those other blockchains do. The distinction between them and bitcoin is that for Bitcoin the security and decentralization means something, for many other projects it's just a costume to hide asset issuance from regulatory authority. BSV obviously doesn't care but it doesn't seem like it has any substantial technical contributors or at least not any that aren't just undermining it through malicious compliance.
I honestly believed that and the last straw was after reading the sentence from the Hight Court of England and Wales, I was convinced I was wrong. I wanned all this year to come back and write that I was wrong but just forgot. Today, I sold all my BSV and decided to come along and write what I should have written last year.
It is important for me to remain honest, although it is not always possible.
I'd be interested in knowing more about your story with BSV and Wright-- how you fell for it, how your thinking changed, etc. While certainly some of us would never have fallen for Wright, there are different things we might fall for. No one is immune to being fooled and I think there are still lessons to be learned. Unfortunately, most people that become disenchanted just disappear completely which limits how much can be learned from them.
