Bitcoin and chains · 11 / 86
Other chains
Other chains change the speed, the fee, the language, and who runs the validators. They do not change the check.
What changes
Some chains confirm faster. Some are cheaper to spam, which also makes some attacks cheaper. Some are run by a small, known set of validators. A small set is easier to pressure.
What stays
A copied name is still copied. A seed is still the wallet. An exchange balance is still not your keys.
Do not trust a chain because it is new, fast, or cheap. Cheap can mean the cost of cheating is low.
Check yourself
Does a faster chain mean a safer coin?
No. Speed is not the check.
After this you can compare two chains by who can stop them, not by the slogan on the homepage.
