Questions about bitcoin architecture and Ripple?

Question

bitcoin

Interested in some specific questions on the architecture of bitcoin, the answers to which I could not find an answer, or the answer was not entirely clear to me, a more detailed explanation is needed. So, point by point:
1. If such sites as blockchain.com/.info and bitcoin.org are suspended, how will this affect the network?
2. Are such domain names hardwired into the architecture, without which the operation of the system is impossible?
3. Is it possible to get a list of all hashes that will be calculated? By what principle does it work, is it impossible to form a new hash until the previous one is calculated, or is there a certain list of hashes that was originally built into the architecture?
4. If the work of the 10 largest exchangers is suspended, how much can the exchange rate drop to? Will it recover over time to its previous value? And to recover at all?
There is such a cryptocurrency as Ripple. I did not find a default wallet for it, which is acceptable for bitcoin, as far as I remember Bitcoin Core, it was the very first wallet from the original author, and in order to use it, you need to download the entire transaction database. Is there something like that for Ripple, not intermediaries? Suppose there was a Rippex intermediary wallet for this crypt, it closed and it turns out that everyone who did not have time to exchange flew by.

Answer 1

1) Technically, this will not affect the operation of the network, because there are many other participants in the network.
2) Domain names are most likely protected, but even without them the system will still work.
3) You are most likely talking about the TX hash that is formed as a result of sending a transaction, you can get a list of all the hashes in the block, as far as I read, the hashes are formed for each block in a separate list and do not depend on other hashes (because the hash itself is still obtained before the validation operations take place). Is that the uniqueness within the block should be.
4) there is generally a theory, it’s unlikely that someone will answer exactly

Answer 2

Domains != miners
