I agree with this concept. We talk about an alt coin. It might be merge-mined with Bitcoin. From your perspective, what fundamental characteristics of Bitcoin shouldn't be changed? What could be sacrificed?
Here is a short list:
1. 21 min supply cap
2. Max block size
3. Average block rate
4. (your version)
Immutability, censorship-resistant.
Anything that we have in Bitcoin shouldn't be changed without a good reason or a necessity. Block size, for example are necessary to be changed because they cannot fulfill the objectives of Bitcoin and remain scalable. Stealing someone else's coins wouldn't be necessary at all, and is absolutely one of the core characteristics of Bitcoin.
I agree. Can we have a tps without corrupting immutability and censorship-resistance in its pure Bitcoin meaning?
Also people might have different perspective on what is "immutability" and "censorship-resistance". Sad but true.
