quote: The true difference between Zcash and Bitcoin is culture.
Bitcoin values stasis, Zcash values progress.
In an age of unprecedented technological discovery and growth, progress is needed. https://x.com/QwQiao/status/2097321622755500269 | the biggest diff between bitcoin and zcash imo is not privacy or quantum resistance, but the fact that the latter is capable of changes and the former is not.
and this is a tradeoff rather than strict superiority. ossification of bitcoin does offer stronger guarantee of immutability and fixed supply, whereas zcash can better adapt to the latest threats (eg quantum) and user needs (eg growing privacy concerns).
this is why if believe in the value of non-sovereign money u probably want to hold both (at a ratio that reflects their relatively level of maturity and risk).

reply @n1ckler @robin_linus > Our rationale for using SHA-256 is that Bitcoin's security already relies so much on it.
I agree this is a great point. It would be nice to have a complete analysis of "What happens is SHA-256 breaks but BLAKE3 doesn't or the other way around?". ⤵️

reply @n1ckler @robin_linus So I think as of today on current CPUs, BLAKE3 would cost about half as much (in time and energy) as SHA-256, and I think that over the coming years that gap might widen even more. ⤵️

reply @n1ckler @robin_linus But look at the column of blue checkmarks in that table: SIMD improvements. They keep coming. SIMD improvements benefit both SHA-256 and BLAKE3, but they benefit BLAKE3 *more*, potentially a lot more, like at least twice as much. ⤵️

reply @n1ckler @robin_linus So my point is, the most recent CPU improvements targeted at specific crypto algorithms have skipped over SHA-256 and improved other crypto algorithms. ⤵️
