They can start with just the UTXOs, 2GB, and the last few blocks plus a checkpoint.

- gruez 9y agowhich has to be from a trusted source because you can't verify anything with just the UTXO + last few blocks.
- sillysaurus3 9y agoIndeed. My main concern is that core tech (e.g. the standard Bitcoin app) has never had a massive security breach. But the only way to use it is if consumers can realistically download the entire blockchain. I guess it was just a matter of time until this happened, though ideally it would've been many years rather than two years.
- MichaelGG 9y agoYou always need a trusted source! So making the trust the first block or the millionth... Not sure there's much difference.
- zaphar 9y agoExcept that the first block and the millionth are not of equal value so there is very definitely a difference in risk when trusting one over the other. The information that the millionth block is safeguarding is way more valuable than the information the first block is guarding. You can't really treat them equivalently.
